Healthcare services must be guided by biosafety practices and microbial control. This control is highly influenced by humidity, which directly impacts the maintenance of sterility of the materials used in the appointments. High concentration of moisture, in the form of aerosol, splashes and spills, is caused during dental care. During the COVID-19 times the contamination by aerosol and droplets worries greatly. Considering that it could cause harm to the sterility of an autoclaved material, especially in dental environments, the objective was to evaluate the behavior of SMS sterilization packages (Spunbonded / Meltblown / Spunbonded) against microbial penetration in an aqueous vehicle. SMS of three brands were challenged, equally divided into two groups: virgin and processed (subjected to a single autoclaving cycle). Each specimen was aseptically deposited on Macconkey agar. Subsequently, 5 µL of Escherichia coliATCC 25922 saline solution [108CFU mL-1] was deposited in center of the SMS specimen and the dish incubated at36°C/ 48h. Reading was performed by the presence or absence of bacterial growth typical of the species under the SMS, observed on the back of Petri dish. The lowest penetration rate observed was 60% for one of the brands in the virgin condition, and 75% for two brands in the processed condition. Statistical analysis showed an association between bacterial penetration and the evaluated group, this association being valid only in the virgin condition. The different SMS behave similarly in terms of resistance to bacterial penetration after being processed. The data show that moisture can assist in bacterial transport through sterilized SMS. Therefore, SMS packages are not able to prevent bacterial penetration, and possibly other microorganisms, when in aqueous vehicles, offering a potential risk of breaking the aseptic chain. Thus, care must be taken in routines for handling and storage sterile packaging.

Abstract Suitability of developing Spirulina incorporated cereal based low cost nutritious extrudates was analysed against extrusion processing parameters. Most significant extrusion processing parameters considered for present study were feed moisture (20-25%), die temperature (100-120 °C) and screw speed (50-100 rpm). Different extrusion conditions were used to obtain most acceptable rice: Spirulina blend extrudates. In present study before extrusion processing different additives (citric acid and sodium bicarbonate) were added in rice: Spirulina blend and checked its effect on colour degradation kinetics at varied packaging and storage conditions. Higher screw speed (100 rpm) indicating less residence time of feed material inside the barrel resulted in higher colour retention of rice: Spirulina (97:03) blend extrudates. Kinetics for rice: Spirulina (97:03) blend extrudates indicates faster rate of colour degradation in terms of lightness (half-life of 4 days) when packed in metalized polyethylene at 50°C with 65% relative humidity. Increased concentration of Spirulina (1-3%) in raw formulations resulted in increase in concentration of all amino acids. Impact of extrusion processing has shown non-significant (p ≤ 0.05) effect on amino acid concentrations of rice: Spirulina blend extrudates. Also, all the spirulina added samples showed good consumer acceptability with the score of 6.7

O mel de abelha é um produto de consumo relevante pela população devido aos seus fatores nutricionais e terapêuticos. A adulteração é um exemplo de como as características do mel podem ser afetadas, prejudicando os consumidores que desejam comprar produtos puros e de alta qualidade. Este trabalho teve como objetivo avaliar a qualidade físico-química do mel de abelha comercializado em Brasília, Distrito Federal. Foram obtidas 13 amostras de mel de abelhas: uma de um apicultor da região com certificação de produção (usada como controle negativo), seis de lojas de produtos naturais e hipermercados no centro de Brasília e seis de feira livre e pequenos estabelecimentos de uma região administrativa do Distrito Federal, das quais cinco não tinham o selo do Serviço de Inspeção Federal (SIF) na embalagem. Também foi usada uma amostra comercial de xarope de glicose como controle positivo. Para verificar a adulteração, foram adotados os testes de Lund, Fiehe e Lugol, bem como as análises de pH, acidez titulável e umidade, para serem comparados com os parâmetros de qualidade do mel estabelecidos pela legislação vigente. As análises verificaram a qualidade dos méis comercializados com o selo SIF, com algumas ressalvas para a possível alteração de temperatura. Já as que não possuíam selo, apenas uma foi aprovada nos testes de qualidade, porém sua venda não é regularizada. A maioria das amostras analisadas apresentaram resultados consistentes com os padrões exigidos pela legislação vigente, com maiores irregularidades na comercialização de méis em feira livre, mostrando a necessidade de maior controle de qualidade e inspeção de produtos não certificados.(AU)

Bee honey is a product of relevant consumption by the population due to its nutritional and therapeutic factors. Tampering is an example of how honey characteristics can be affected and harming consumers who want to buy a high quality and pure product. This work aimed to evaluate the physicochemical quality of bee honey commercialized in Brasília, Federal District. Thirteen samples of bee honey were obtained: one from a certified local beekeeper (used as a negative control), six from natural products and hypermarkets in central Brasília and six from street fair and small establishments in one of the administrative region of the Federal District, of which five did not have the seal of the Federal Inspection Service (SIF) on the packaging. Also, a sample of commercial glucose syrup was used as positive control. To verify tampering, the Lund, Fiehe and Lugol tests were adopted, as well as the pH, titratable acidity and humidity analysis, to be compared honey quality parameters established by the current legislation. The analyzes verified the quality of the honeys sold with SIF seal, with some restraints for the possible temperature changes. As for those that did not have a seal, only one passed the quality tests, but its sale is not regularized. Most of the samples analyzed showed results consistent with the standards requirements of the current legislation, with greater irregularities in the marketing of honey in street fair, showing the need for greater quality control and inspection of non-certified products.(AU)

Bisphenol A (BPA), an endocrine disrupter, can migrate from packaging material into food stuff. This research was designed to measure BPA levels in makdous, a traditional Syrian food. Forty three samples of makdous stored in different plastic containers (polyethylene (PE), polypropylene (PP), and unspecified plastic containers) were analyzed every 3 months for one year beginning July 2017. Quantification of BPA was carried out by an RP-HPLC system equipped with fluorescence detector after solid phase extraction. Migration was found in PE and PP plastic containers with slight differences. Statistically significant differences in BPA levels were observed between samples assayed after two weeks of preparation and samples assayed after 12 months (mean 16.32 vs. 38.26 µg/kg, p value=0.003). According to these amounts, BPA levels were all under the specific migration limit of 0.05 mg/kg as newly referred in Regulation (EU) No 2018/213. These levels of exposure would only contribute to 2.15% and 2.75% of the EFSA t-TDI in both men and women respectively based on mean dietary exposure estimates derived from a 24-h dietary information study from 875 participants. Hence there are no concerns about potential health risks from makdous consumption

A crescente rejeição às gorduras saturadas e trans em decorrência de sua associação com doenças cardiovasculares, entre outras desordens metabólicas de diversas naturezas, tem impulsionado o desenvolvimento de alternativas às gorduras tradicionalmente utilizadas nos processamentos de alimentos. Contudo, o grande desafio reside em conferir funcionalidade tecnológica a lipídios ricos em ácidos graxos insaturados, sendo os oleogéis uma abordagem viável e promissora. Os oleogéis são sistemas constituídos por uma base lipídica composta por óleo no estado líquido estruturada por uma rede tridimensional de moléculas com solubilidade limitada em óleos, chamadas de agentes estruturantes. Estudos recentes relataram a influência do tipo de óleo no processo de formação da rede tridimensional de agentes estruturantes e concluíram que o tamanho da cadeia, a polaridade e a viscosidade do óleo podem afetar grandemente a estrutura do oleogel. Diante disto, o objetivo deste estudo é investigar a influência do tipo de óleo em sua estruturação por cera de candelilla, relacionando as propriedades físicas dos oleogéis formados com diversas características físico-químicas dos óleos que os compõem. Para avaliar esta influência, foram selecionadas bases lipídicas de diferentes composições, como triacilgliceróis de cadeia média (MCT), óleo de girassol alto oleico (HOSO), óleo de girassol (SFO), óleo de linhaça (LSO) e os óleos unicelulares ARASCO e DHASCO, para serem estruturados com cera de candelilla nas concentrações de 1,5, 3,0 e 6,0%. De acordo com as correlações de Pearson estabelecidas, houve uma correlação muito forte (r2 =0,948) entre a firmeza e o conteúdo de ácidos graxos saturados dos óleos, o que pode estar relacionado a uma co-cristalização entre a cera e os ácidos graxos saturados, formando uma estrutura mais firme. Uma correlação forte também foi estabelecida entre o tamanho médio das cadeias de ácidos graxos dos óleos, definido pelo índice de saponificação, e a firmeza dos oleogéis (r2 =0,864). A densidade dos óleos também apresentou correlação forte com a firmeza dos oleogéis (r2 =0,858), assim como a viscosidade apresentou uma forte correlação negativa (r2 = -0,818), o que indica que os óleos mais densos e menos viscosos produzem oleogéis mais firmes. Tanto a cera de candelilla pura quanto os oleogéis apresentaram forma polimórfica ß', que equivale à subcélula ortorrômbica, que demonstra que os diferentes óleos não modificaram a microestrutura da rede de cera de candelilla. Os diferentes tipos de óleo exerceram influência sobre o comportamento de fusão dos oleogéis, fator que permitiu associá-lo a um maior conteúdo de gordura sólida a 20 °C e a um maior teor de triacilgliceróis trissaturados, como nos óleos DHASCO e ARASCO. O grau de insaturação dos óleos influenciou o empacotamento da rede estrutural dos oleogéis, o que foi revelado pela menor perda de óleo nos oleogéis com cadeias mais longas, se comparados ao MCT. Por fim, este trabalho contribuiu com a expansão do conhecimento dos sistemas chamados oleogéis, sugerindo que trabalhos futuros pautem as escolhas de matéria-prima para formulação dos oleogéis nas propriedades de seus componentes. Desta forma, maiores avanços poderão ser alcançados nas pesquisas de sistemas coloidais e consequentemente no desenvolvimento de sistemas de alta qualidade nutricional e, ao mesmo tempo, funcionalidade tecnológica adequada

The growing rejection of saturated and trans fats as a result of their association with cardiovascular diseases, among other metabolic disorders of various kinds, has driven the development of alternative systems to substitute fats traditionally used in food processing. However, the big challenge lies in providing technological functionality to lipids rich in unsaturated fatty acids, with oleogels being a viable and promising approach. Oleogels are systems made up of a lipid base composed of oil in a liquid state structured by a threedimensional network of molecules with limited solubility in oils, called oleogelators. Recent studies have reported the influence of the oil type in the formation process of the threedimensional network of oleogelators and concluded that the fatty acid chain length, the polarity and the viscosity of the oil can greatly affect the structure of the oleogel. In view of this, the objective of this study is to investigate the influence of the oil type in its structuring by candelilla wax, relating the physical properties of the formed oleogels with several physicochemical characteristics of the oils that compose them. To evaluate this influence, lipid bases of different compositions were selected, such as medium chain triglycerides (MCT), high oleic sunflower oil (HOSO), sunflower oil (SFO), linseed oil (LSO) and ARASCO and DHASCO single-cell oils, to be structured with candelilla wax in concentrations of 1.5, 3.0 and 6.0% (w/w). According to the Pearson correlations established, there was a very strong correlation (r2 = 0.948) between the firmness and the saturated fatty acid content of the oils, which may be related to a co-crystallization between the wax and the saturated fatty acids, forming a firmer structure. A strong correlation was also established between the average size of the fatty acid chains of the oils, defined by the saponification value, and the oleogel firmness (r2 = 0.864). The density of the oils also showed a strong correlation with the firmness of the oleogels (r2 = 0.858), as well as the viscosity, which showed a strong negative correlation (r2 = -0.818), indicating that oils with higher density and lower viscosity produce firmer oleogels. Both pure candelilla wax and oleogels presented the ß' polymorphic form, which is equivalent to the orthorhombic subcell, demonstrating that the different oils did not modify the microstructure of the candelilla wax network. The different types of oil influenced the melting behavior of oleogels, a factor that allowed it to be associated with a higher solid fat content at 20 °C and a higher content of trisaturated triacylglycerols, as in DHASCO and ARASCO oils. The degree of unsaturation of the oils influenced the packaging of the structural network of oleogels, which was revealed by the higher oil binding capacity in oleogels with longer chains, compared to MCT. Finally, this work contributed to the expansion of knowledge of oleogel systems, suggesting that future work will guide the choices of raw material for formulating oleogels in the properties of their components. Thus, greater advances can be achieved in the research of colloidal systems and, consequently, in the development of high nutritional quality systems allied to adequate technological functionality

Food prepared with products derived from animals are involved in most cases of staphylococcal poisoning; therefore, the research of Staphylococcus spp. in Emmental cheese is more applicable. The objective of this study was to identify coagulase-negative Staphylococcus spp. (CNS) in cheese using biochemical and molecular techniques to detect the presence of nine genes responsible for the production of enterotoxins. From 180 samples analyzed, 204 CNS strains were obtained and identified as being 46 (22.6%) S. saprophyticus strains, 27 (13.2%) S. hominis spp. hominis strains, 22 (10.8%) S. sciuri strains, 21 (10.3%) S. xylosus strains, 19 (9.3%) S. epidermidis strains, 19 (9.3%) S. haemolyticus strains, 17 (8.3%) S. lentus strains, 17 (8.3%) S. warneri strains, 11 (5.4%) S. equorum strains and 5 (2.5%) S. cohnni . Using the PCRm protocol, 14 (6.9%) strains with the presence of the genes on the enterotoxin E (SEE)11 (78.6%), J (SEJ) 1 (7%), C (SEC) 1 (7%) and I (SEI) 1 (7%) were detected. Based on the results, the type of package is not interfered of growth and isolated that Staphylococcus spp. in cheese. It was observed that bacteria capacity to produce coagulase cannot be understood as an indicative of enterotoxigenicity; therefore, the CNS should be considered as a target of importance in the epidemiology of staphylococcal intoxications. It can be concluded that CNS need to be included in bacterial foodborne disease research, since the genes responsible for the production of toxins were detected and none of the studied samples presented Staphylococcus spp. counting above the limits allowed by legislation.(AU)

Os alimentos preparados com produtos de origem animal são os mais envolvidos em casos de intoxicação alimentar estafilocócica; portanto a pesquisa do Staphylococcus spp. em queijos tipo Emmental é relevante. O objetivo foi isolar e identificar espécies de Staphylococcus coagulase negativas (CNS)de queijo Emmental acondicionado em vários tipos de embalagem, por meio de técnicas bacteriológicas e bioquímicas e detectar, por PCR, a presença de nove genes responsáveis pela produção de enterotoxinas. Das 180 amostras, foram isoladas 204 cepas de CNS, que foram identificadas por provas bioquímicas como: 46 (22,6%) S. saprophyticus, 27 (13,2%) S. hominis spp. hominis, 22 (10,8%) S. sciuri, 21 (10,3%) S. xylosus, 19 (9,3%) S. epidermidis , 19 (9,3%) S. haemolyticus , 17 (8,3%) S. lentus , 17 (8,3%) S. warneri , 11(5,4%) S. equorum e 5 (2,5%) S. cohnii . Na PCR multiplex, em 14 (6,9%) isolados foi detectada a presença dos genes para enterotoxina E (SEE), em 11 (78,6%) J (SEJ), em 1 (7%) C (SEC) e em 1 (7%) I (SEI). Com base nos resultados, o tipo de embalagem não interferiu na multiplicação dos Staphylococcus spp. isolados dos queijos. Neste estudo, verificou-se que a capacidade para a produção de coagulase pela bactéria não pode ser concebida como indicativa de enterotoxigenicidade, portanto devem-se considerar os CNS como objeto de importância na epidemiologia das intoxicações estafilocócicas, fazendo-se necessária a atenção com relação à pesquisa dos CNS nos alimentos, uma vez que foram detectados genes responsáveis pela produção de toxinas, e nenhuma das amostras apresentou contagem para Staphylococcus spp. acima do limite permitido pela legislação.(AU)

The objective of the present study was to assess the influence of the packaging material (cotton cloth bag, multifolium paper and glass container) and storage environment (laboratory and cold chamber conditions) on fennel seedling growth. Seeds were placed in different packaging materials and exposed to the two environments for twelve months. Assessments were made before storage and at every two months and the following were determined: total emergence, emergence speed index, seedling fresh and dry matter. A completely randomized experimental design was used, with four replications in a 2 x 3 x 6+1 factorial design in split split plots, where the plot was the storage environment (laboratory and cold chamber conditions); the split plot was the storage (cotton cloth bag, multifolium paper and glass container) and the split plot was the storage periods (2, 4, 6, 8, 10 and 12 months) and plus an additional treatment (before storage). The results showed that the fennel seedlings had superior growth when their seeds were placed in the glass packaging material, regardless of the storage environment.

Tobacco use is the most important preventable cause of mortality in South Korea and worldwide. This study aimed to evaluate the tobacco control policies of the Moon Jae-in government, which was established in May 10, 2017. Before the Moon Jae-in government, the tobacco tax was raised by the Park Geun-hye government from 2,500 won to 4,500 won (80% increase), but the price of cigarettes was still much lower in Korea than in other high-income countries. Cigarette smoking has been prohibited in all restaurants and bars since 2015; however, smoking rooms are allowed. Only large buildings are smoke-free. Pictorial warnings on cigarette packages were introduced in December 2016; however, they cover only 30% of the main packaging. Smoking cessation services provided by health care facilities have been subsidized by public health insurance since 2015. However, the advertisement, promotion, and sponsorship of tobacco are not further regulated. Since the beginning of the Moon Jae-in government, there has been no further strengthening of major tobacco control policies except for limited expansion of smoke-free public places and introduction of a lung cancer screening program. The first government-level tobacco control policies by the Moon Jae-in government, announced in May 2019, included increasing the size of the pictorial warnings and introducing standardized packaging by 2025, along with incremental expansion of smoke-free public places with prohibition of smoking rooms. These moves are positive; however, they do not include increasing tobacco taxes and regulating advertisement, promotion, and sponsorship of tobacco, which together are the backbone of tobacco control policies. The Moon Jae-in government should strengthen comprehensive tobacco control policies, ncluding tobacco taxes and banning tobacco advertisement, promotion, and sponsorship, to protect public health.

BACKGROUND: In implant-based breast reconstruction, acellular dermal matrix (ADM) is essential for supporting the inferolateral pole. Recent studies have compared non-sterilized freeze-dried ADM and sterilized pre-hydrated ADM, but have not assessed whether differences were attributable to factors related to sterile processing or packaging. This study was conducted to compare the clinical outcomes of breast reconstruction using two types of sterile-processed ADMs. METHODS: Through a retrospective chart review, we analyzed 77 consecutive patients (85 breasts) who underwent tissue expander/implant breast reconstruction with either freeze-dried ADM (35 breasts) or pre-hydrated ADM (50 breasts) from March 2016 to February 2018. Demographic variables, postoperative outcomes, and operative parameters were compared between freeze-dried and pre-hydrated ADM. Biopsy specimens were obtained for histologic analysis. RESULTS: We obtained results after adjusting for variables found to be significant in univariate analyses. The total complication rate for freeze-dried and pre-hydrated ADMs was 25.7% and 22.0%, respectively. Skin necrosis was significantly more frequent in the freeze-dried group than in the pre-hydrated group (8.6% vs. 4.0%, P=0.038). All other complications and operative parameters showed no significant differences. In the histologic analysis, collagen density, inflammation, and vascularity were higher in the pre-hydrated ADM group (P=0.042, P=0.006, P=0.005, respectively). CONCLUSIONS: There are limited data comparing the outcomes of tissue expander/implant breast reconstruction using two types of sterile-processed ADMs. In this study, we found that using pre-hydrated ADM resulted in less skin necrosis and better integration into host tissue. Pre-hydrated ADM may therefore be preferable to freeze-dried ADM in terms of convenience and safety.

This study provides basic data on how stress impacts the processed convenience foods purchase attitudes and the selection attributes of housewives. The stress consists of 3 factors, which were housework stress, family relation stress and economic stress. The processed convenience food purchase attitude consisted of 2 factors, which were peripheral influence purchase and conviction purchase. The processed convenience food selection attribute consisted of 4 factors, which were quality, convenience, packaging and price. Factor loading confirmation and reliability test were conducted, and the reliability was confirmed with Cronbach's alpha coefficients for all the factors exceeding 0.5. The high stress levels showed significantly high stress factors of housework, family relations and economic stress (P<0.001). The high stress group was shown to make purchases by recognizing peripheral influences (P<0.01). When the selection properties of processed convenience foods depending on different stress levels were examined, it was revealed that among the three groups, the low stress group least considered the price aspect (P<0.01). After deducting the factors, AMOS (Analysis of Moment Structure) was used to conduct the confirmatory factor analysis for verifying validity. The structural equation model was used to determine the path coefficient. From the processed convenience foods purchase attitude, the peripheral influence purchase had significantly positive (+) effects on convenience (P<0.05). Also, conviction purchase was shown to have significantly positive (+) effects on quality (P<0.05). Housework and family relation stress were shown to have negative (−) effects on processed convenience foods selection attribute, and economic stress was shown to have positive (+) effects, although no significant relationships were revealed.

Although intravesical instillation of Mycobacterium bovis bacillus Calmette-Guérin (BCG) is the most successful cancer immunotherapy for superficial bladder cancer, the serious side effects are frequently arisen by using live mycobacteria. To allow less toxic and more potent immunotherapeutic agents following intravesical BCG treatment for superficial bladder cancer, noninfectious immunotherapeutic drug instead of live BCG would be highly desirable. Recently, immune-enhancing adjuvants are considered an effective vaccine immunotherapy for cancer, providing enhanced antitumor effects and boosted immunity. The BCG-cell wall skeleton (BCG-CWS), the main immune active center of BCG, is a potent candidate as a noninfectious immunotherapeutic drug instead of live BCG against bladder cancer. However, the most limited application for anticancer therapy, it is difficult to formulate a water-soluble BCG-CWS due to the aggregation of BCG-CWS in both aqueous and nonaqueous solvents. To overcome the insolubility and improve the internalization of BCG-CWS into bladder cancer cells, it should be developed the lipid nanoparticulation of BCG-CWS, resulting in improved dispensability, stability, and small size. In addition, powerful technology of delivery systems should be applied to enhance the internalization of BCG-CWS, such as encapsulated into lipid nanoparticles using novel packaging methods. Here, we describe the progress in research on effects of BCG-CWS for cancer immunotherapy, development of lipid-based solvent, and packaging method using nanoparticles with drug delivery system.

O objetivo deste estudo foi desenvolver e caracterizar filme indicador de qualidade de alimentos utilizando amido de banana verde incorporado com extrato de repolho roxo. Os filmes foram desenvolvidos a partir de duas formulações: i) amido de banana sem extrato; ii) amido de banana com extrato. Os filmes foram caracterizados através de análise térmica (TG/DT), ensaio mecânico, espectroscopia por infravermelho (FT-IR), índice de intumescimento e ativação em diferentes pH. Os filmes apresentaram um perfil similar de perda de massa, indicando pouco efeito da incorporação do extrato à sua estabilidade térmica. A incorporação do extrato vegetal promoveu maior resistência mecânica e menor taxa de intumescimento. FT-IR mostrou que não houve interação do extrato com o biopolímero. O filme de amido apresentou sensibilidade à variação do pH. O uso do amido de banana verde combinado com gelatina e extrato de repolho roxo apresenta potencial aplicação como indicador visual de qualidade de alimentos duranteo armazenamento.

The aim of the study was to develop and characterize food quality indicator film using green banana starch incorporated with purple cabbage extract. The films were developed from two formulations: i) banana starch without extract; ii) banana starch with extract. The films were characterized by thermal analysis (TG/DTA), mechanical assay, infrared spectroscopy (FT-IR), swelling index and activation at different pH. The films presented a similar profile of mass loss, indicating that extract did not affect thermal stability. The incorporation of the vegetal extract promoted greater mechanical resistance and a lower rate of swelling. FT-IR showed that there was no interaction of the extract with the biopolymer. The starch film showed sensitivity to pH variation. The use of green banana starch combined with gelatin and purple cabbage extract has potential application as a visual indicator of food quality during storage.

O acondicionamento de bebidas carbonatadas em embalagens de alumínio e o aumento do consumo, intensifica a preocupação com relação à contaminação da superfície a ter contato com a boca e à necessidade da higienização das embalagens. O objetivo deste trabalho foi avaliar a contaminação microbiológica, por meio da pesquisa de coliformes totais, coliformes termotolerante, Escherichia coli, contagem total de bactérias aeróbias mesófilas e contagem total de bolores e leveduras, na superfície superior externa de latas de cervejas e de refrigerantes, refrigerados comercializadas em bares, restaurantes, ambulantes e quiosques; bem como avaliar a influência do selo de alumínio na proteção contra a contaminação em latas de cerveja. Foram avaliadas 90 latas de alumínio, sendo 30 seladas e 30 não seladas contendo cerveja e 30 latas não seladas contendo refrigerante. Os resultados mostraram que 34% das amostras estavam contaminadas por coliformes totais, sendo observado valor igual ou superior a 2400 NMP/cm² em uma amostra de cerveja selada e cerveja não selada, adquiridas de ambulante, e uma amostra não selada adquirida de bar. Quanto a coliformes termotolerante 2,2% das embalagens estavam contaminadas, sendo este detectado em duas amostras de cerveja não selada (4 e 7 NMP/cm²) proveniente de bar. Não foi detectada Escherichia coli nas amostras analisadas. Bactérias aeróbias mesófilas foram detectadas em 84 (93,3%) amostras, sendo a maior contagem observada em uma amostra de refrigerante adquirida de quiosque, com o valor de 2,8x10³ UFC/cm². A contaminação por bolores e leveduras foi observada em 59 (65,5%) amostras, sendo a maior contagem com o valor de 2,7x10³ UFC/cm², observada em uma embalagem de cerveja não selada. Concluiu-se que latas seladas ou sem selo apresentaram níveis de contaminação semelhante, indicando que o selo não promove proteção contra contaminação e as amostras que apresentaram maior contaminação foram aquelas refrigeradas em caixas de isopor com água e gelo.

The packaging of carbonated beverages in aluminum packaging and the increase in consumption increases the concern with regard to contamination of the surface to have contact with the mouth and the need for hygiene of the packages. The objective of this study was to evaluate the microbiological contamination of the external surface of beers and refrigerated cans, commercialized in bars, restaurants, street vendors and kiosks; as well as to evaluate the influence of the aluminum seal in the protection against contamination in beer cans. the following analyzes were performed: total coliforms, thermotolerant coliforms, Escherichia coli, count of mesophilic aerobic bacteria and counts of molds and yeasts. Ninety aluminum cans were evaluated, of which 30 were sealed and 30 unsealed containing beer and 30 unsealed cans containing refrigerant. The results showed that 34% of samples were contaminated by total coliforms, with a value of 2400 NMP / cm² being observed in a sample of sealed beer and unsealed beer, purchased on the street, and an unsealed sample purchased from the bar. Regarding thermotolerant coliforms, 2.2% of the packages were contaminated, being detected in two samples of unsealed beer (4 and 7 NMP / cm²) from the bar. No Escherichia coli was detected in the analyzed samples. Mesophilic aerobic bacteria were detected in 84 (93.3%) samples, the highest observed in a sample of kiosk purchased refrigerant, with a value of 2.8x10³ CFU / cm². Contamination by molds and yeasts was observed in 59 (65.5%) samples, the highest count being 2.7x10³ CFU / cm², observed in an unsealed beer package. It was concluded that sealed or unsealed cans had levels of similar contamination, indicating that the seal does not promote protection against contamination and the samples that presented the highest contamination were those refrigerated in styrofoam boxes with water and ice.

Diante do grande consumo de bebidas alcoólicas no Brasil e no mundo, muitas empresas têm investido na confecção de embalagens cada vez mais promissoras. Com o objetivo de conhecer o perfil de consumo de cervejas e vinhos relacionado às suas respectivas embalagens, foi desenvolvida uma pesquisa na cidade de Salvador-BA, sendo entrevistadas 221 pessoas cujo consumo das bebidas estava intrinsecamente ligado ao ambiente social. A prevalência de consumo é das cervejas com cerca de 26,7%, sendo que os principais locais de dispêndio com a mesma são festas e bares. Vale salientar que a embalagem escolhida por 93,3% dos participantes é a de vidro. Observa-se então um crescimento favorável das indústrias cervejeiras no Brasil com a comercialização deste produto popular em detrimento do vinho, possuinte de um estilo mais elitizado e restrito de consumo.

Due to the large consumption of alcoholic beverages in Brazil and in the world, many companies have made investments to increase the design of its packaging. In order to discover the relation in between the consumption of beers, wine and its packages, a research has been developed in Salvador (BA). Therefore, 221 people were interviewed, concluding that the beverage choice was intrinsically related to the social environment. Furthermore, this study highlights the predominance of beers in front of wines consumption. This scientific enquire points the development of beers industries in Brazil, but also spotlight the decrease of wine consumption due to its elitist stigma.
