RESUMO

The effect of the substitution of emulsifying salt by the young bamboo flour (BF) (0, 25, 50, 75, 100 % w/w) on requeijão cremoso processed cheese [REQ, REQ 25, REQ 75 REQ 100]) processing was investigated. Gross composition, calcium and sodium values, functional properties (melting rate), color parameters (L, a*, b*, C*, and Whiteness Index, WI), texture profile, fatty acid profile, volatile organic compounds (VOCs), and sensory profiling were evaluated. No effect was observed on the gross composition; however, sodium and melting rate values were decreased, and calcium values presented the opposite behavior. BF could modify the optical parameters, observing an increase in WI values. Higher BF addition increased hardness and lowered elasticity, and regarding the fatty acid profile, there is no significant difference. Different volatile compounds were noted in a proportional form with the BF addition, which was reflected in similar sensory acceptance for REQ 25 and control samples. Although some aspects require further in-depth studies, using BF as a substitute for emulsifying salt in requeijão cremoso processed cheese appears to be a viable option, especially when considering partial replacements.

RESUMO

In this initial study, the impact of thermosonication as an alternative to the traditional fusion in Brazilian cheese spread (Requeijão Cremoso) manufacture was investigated. The effect of ultrasound (US) power was evaluated considering various aspects such as gross composition, microstructure, texture, rheology, color, fatty acid composition, and volatile compounds. A 13 mm US probe operating at 20 kHz was used. The experiment involved different US power levels (200, 400, and 600 W) at 85 °C for 1 min, and results were compared to the conventional process in the same conditions (85 °C for 1 min, control treatment). The texture became softer as ultrasound power increased from 200 to 600 W, which was attributed to structural changes within the protein and lipid matrix. The color of the cheese spread also underwent noticeable changes for all US treatments, and treatment at 600 W resulted in increased lightness but reduced color intensity. Moreover, the fatty acid composition of the cheese spread showed variations with different US power, with samples treated at 600 W showing lower concentrations of saturated and unsaturated fatty acids, as well as lower atherogenicity and thrombogenicity indexes, indicating a potentially healthier product. Volatile compounds were also influenced by US, with less compounds being identified at higher powers, especially at 600 W. This could indicate possible degradation, which should be evaluated in further studies regarding US treatment effects on consumer perception. Hence, this initial work demonstrated that thermosonication might be interesting in the manufacture of Brazilian cheese spread, since it can be used to manipulate the texture, color and aroma of the product in order to improve its quality parameters.

RESUMO

Boursin is a versatile semisoft cheese that can be made with different types of milk. While widely distributed in the European and North American markets, Boursin is produced to a limited extent in Brazil despite its commercial potential. This scenario encourages consumer-oriented product development studies by facilitating data collection with less bias and fewer product preconceptions, thus favoring the investigation of technological aspects of commercial interest. This study evaluates Brazilians' perceptions regarding different versions of Boursin cheese, with the aim of gaining a better understanding of the factors related to choosing cheese. Four attributes related to cheese production were evaluated at three different levels using two discrete choice experiments: one with eye tracking (n = 20) and another without (n = 312). These attributes included "type of processing" (evaluating pasteurization, ohmic heating, and preparation with raw milk), "animal origin of milk" (cow, goat, or buffalo milk), "type of product" (traditional, light, and lactose-free versions), and "price" (10.99, 13.99, and 16.99 BRL). Information regarding processing with ohmic heating did not affect the probability of Boursin being chosen, suggesting that consumers are open to using this emerging technology in Boursin cheese. However, information on being made with goat, buffalo, and raw milk negatively impacted the probability of choice, along with the price of 16.99 BRL. The frequency of cheese consumption and the level of health concerns also affected the probability of choosing the product. PRACTICAL APPLICATION: Identifying the relationship between extrinsic attributes presented on the Boursin cheese label and the consumer's choice process can aid the communication process with the target audience and reveal how some technological issues of interest to manufacturers are perceived. This study indicates how information regarding the animal origin of the milk (cow, goat, and buffalo), the type of processing (pasteurization, ohmic heating, and raw milk), the version of the product (traditional, light, and lactose-free), and the price affect the consumer choice process. The results provide insights that can be applied to product processing and designing labels.

RESUMO

Dairy products stand out as a food matrix susceptible to the contamination of heavy metals via cattle feed and environmental or processing conditions. Specifically, in the case of cheese, the concentrations can be further increased depending on the production process. The artisanal cheese market has been standing out, especially in Brazil, due to cultural and gastronomic reasons. Eight types of Brazilian artisanal cheese were analyzed for metal concentrations (chromium, copper, cadmium, lead, arsenic, and mercury, n = 80, 10 samples of each cheese) using inductively coupled plasma mass spectrometry. Based on the results, a health risk assessment was carried out, based on the determination of estimated daily intake, target hazard quotient (THQ), and hazard index (HI). Variable concentrations were observed between the types of cheese, but in all cases the THQ and HI values were less than 1, indicating an absence of potential risk in the consumption of artisanal cheeses in relation to the intake of heavy metals.

RESUMO

The relationship between the consumption of hyper-palatable ultra-processed foods and the process of addiction gains notoriety due to its relationship with obesity. Food addiction is a complex phenomenon intrinsically related to the individual's behavioral, emotional, and subjective aspects. Therefore, using classical approaches to sensory science may be insufficient to understand better the individual's sensory experience with hyper-palatable foods. In this context, sensory and consumer science techniques with holistic approaches have been aimed at accessing more subjective consumer perceptions. This study used the Yale Food Addiction Scale (YFAS 2.0) to investigate the prevalence of food addiction and the Structured Projective Mapping (S-MP) and Sorting techniques to verify how individuals with and without food addiction perceive and understand different types of food. The prevalence of food addiction was 21.77% (n = 59 out of 271) and was associated with a higher BMI but not with sociodemographic aspects. Projective Mapping (RV = 0.937) and Sorting (RV = 0.934) indicated that perception in relation to attributes such as health and pleasure was similar for all investigated foods in individuals with or without food addiction. The presence of addictive eating behavior does not seem to be related to the way individuals perceive foods from different categories, for example, minimally or highly processed and hyper-palatable foods.

RESUMO

This study investigated the microstructure, rheological properties, and sensory characteristics of butters produced with free and encapsulated xylooligosaccharides (XOS). Four formulations of butter were processed: BCONT: 0 % w/w XOS (control); BXOS: 20% w/w free XOS; BXOS-ALG: 20% w/w XOS microencapsulated with alginate (XOS-alginate ratio of 3:1 w/w); and BXOS-GEL: 20% w/w XOS microencapsulated with alginate-gelatin (XOS-alginate-gelatin ratio of 3:1:1.5 w/w). The microparticles showed a bimodal distribution, low size and low span values, demonstrating physical stability to be included in emulsions. The XOS-ALG presented surface weighted mean diameter (D3.2) of 90.24 µm, volume-weighted mean diameter (D4.3) of 131.8 µm, and Span of 2.14. In contrast, the XOS-GEL presented D3.2 of 82.80 µm, D4.3 of 141.0 µm, and a Span of 2.46. Products with XOS were characterized by higher creaminess, sweet taste, and lower salty taste than the control. However, the addition form significantly impacted the other evaluated parameters. The utilization of XOS in a free form (BXOS) resulted in smaller droplet sizes (1.26 µm) than encapsulated XOS and control (XOS-ALG = 1.32 µm / XOS-GEL = 1.58 µm, / BCONT = 1.59 µm), and changes in the rheological parameters (higher values of shear stress, viscosity, consistency index, rigidity (J0), and Newtonian viscosity (ηN) and lower elasticity (τ)). Furthermore, it changed the color parameters (more yellow and dark color, lower L* and higher b* values). On the other hand, the utilization of micropaticles of XOS (BXOS-ALG and BXOS-GEL) kept shear stress, viscosity, consistency index, rigidity (J0), and elasticity (τ) more similar to control. The products had a less intense yellow color (lower b* values) and was perceived with more consistency and butter taste. However, the presence of particles was perceived by consumers. The results suggest that consumers were more attentive to reporting flavor-related attributes than texture. In conclusion, adding microparticles of XOS could improve butter's rheological and sensory properties. In conclusion, adding microparticles of XOS could improve butter's rheological and sensory properties.

RESUMO

Thermal processes can be very damaging to the nutritional and sensory quality of foods. Non-thermal technologies have been applied to reduce the impact of heat on food, reducing processing time and increasing its efficiency. Among many non-thermal technologies, cold plasma is an emerging technology with several potential applications in food processing. This technique can be used to preserve and sanitize food products, and act as a pre-treatment for drying, extraction, cooking, curing, and hydrogenation of foods. Furthermore, the reacting plasma species formed during the plasma application can change positively the sensory and nutritional aspects of foods. The aim of this review is to analyze the main findings on the application of cold plasma as a pre-treatment technology to improve food processing. In its current maturity stage, the cold plasma technology is suitable for reducing drying time, increasing extraction efficiency, as well as curing meats. This technology can convert unsaturated into saturated fats, without forming trans isomers, which can be an alternative to healthier foods. Although many advantages come from cold plasma applications, this technology still has several challenges, such as the scaling up, especially in increasing productivity and treating foods with large formats. Optimization and control of the effects of plasma on nutritional and sensory quality are still under investigation. Further improvement of the technology will come with a higher knowledge of the effects of plasma on the different chemical groups present in foods, and with the development of bigger or more powerful plasma systems.

RESUMO

Due to the intense competition in the sector, the dairy market maintains a constant search for innovations. Thus, new technologies are incorporated, and new products are constantly launched, increasing the range of consumer options. In this way, the understanding of consumers' motivations, attitudes, and behaviors in the moments of choice, purchase, and consumption are important for the academic public and food industries. This study used the Text Highlighting methodology to assess Brazilian consumers' explicit attitudes towards using high-intensity ultrasound technology in Minas Frescal cheese processing. In the task, consumers were asked to highlight in a text the terms they "liked" or "disliked" about using high-intensity ultrasound in the Minas Frescal cheese processing. A seven-point Likert scale was also used to assess consumers' attitudinal statements. A high engagement of consumers with the Text Highlighting methodology could be observed (43.8-92.3% of text highlighting), which suggests good intuitiveness of the technique. Including information about the benefits of the emerging technology in the product, mainly on sensory and nutritional properties, may increase positive consumer perception, as it promotes the consumers to express their value judgment in the form of "liked". At the same time, the harms of the traditional processing technique prompted consumers to express their value judgment in the "disliked" highlights. It was observed that information should be in a simple and direct language, as technical terminology in the text did not have a positive effect. The categorizing of consumers according to the sentimental score showed that consumers are still reticent to use emerging technologies in Minas Frescal cheese processing. Consumers' attitudinal statements demonstrated that consumers perceive high-intensity ultrasound as a positive idea and safety technology for Minas Frescal cheese processing. Still, they are not willing to pay premium prices. In conclusion, Text Highlighting produced valuable insights that can be used in communication strategies with Minas Frescal cheese consumers.

RESUMO

Flavored milk drink is a popular dairy product traditionally processed by pasteurization, which is a safe and robust process. Still, it can imply a greater energy expenditure and a more significant sensorial alteration. Ohmic heating (OH) has been proposed as an alternative to dairy processing, including flavored milk drink. However, its impact on sensory characteristics needs to be evidenced. This study used Free Comment, an underexplored methodology in sensory studies, to characterize five samples of high-protein vanilla-flavored milk drink: PAST (conventional pasteurization 72 °C/15 s); OH6 (ohmic heating at 5.22 V/cm); OH8 (ohmic heating at 6.96 V/cm); OH10 (ohmic heating at 8.70 V/cm), and OH12 (ohmic heating at 10.43 V/cm). Free Comment raised similar descriptors to those found in studies that used more consolidated descriptive methods. The employed statistical approach allowed observation that pasteurization and OH treatment have different effects on the sensory profile of products, and the electrical field strength of OH also has a significant impact. PAST was slightly to moderately negatively associated with "acid taste," "fresh milk taste," "smoothness," "sweet taste," "vanilla flavor," "vanilla aroma," "viscous," and "white color." On the other hand, OH processing with more intense electric fields (OH10 and OH12) produced flavored milk drinks strongly associated with the "in natura" milk descriptors ("fresh milk aroma" and "fresh milk taste"). Furthermore, the products were characterized by the descriptors "homogeneous," "sweet aroma," "sweet taste," "vanilla aroma," "white color," "vanilla taste," and "smoothness." In parallel, less intense electric fields (OH6 and OH8) produced samples more associated with a bitter taste, viscosity, and lumps presence. Sweet taste and fresh milk taste were the drivers of liking. In conclusion, OH with more intense electric fields (OH10 and OH12) was promising in flavored milk drink processing. Furthermore, the free comment was a valuable approach to characterize and identify the drivers of liking of high-protein flavored milk drink submitted to OH.

RESUMO

The effect of probiotic strains (Lactobacillus acidophilus La-03 (La-03); Lactobacillus acidophilus La-05 (La-05); Bifidobacterium Bb-12 (Bb-12) or Lacticaseibacillus casei-01 (L. casei-01)) on the characteristics of fermented whey-milk beverages during storage (4 °C, 30 days) was evaluated. The products were assessed for biological and antioxidant activities, physicochemical characteristics, and bioactive peptides. Probiotic addition increased α-amylase and α-glucosidase inhibition and antioxidant activities, mainly at 15 days of storage. L. casei-01 showed higher metabolic activity (higher titratable acidity and lower pH values) and the presence of anti-hypertensive peptides, while La-5 and Bb-12 showed higher α-glucosidase inhibition, improvements in the high saturated hypercholesterolemic index, and peptides with ACE-inhibitory, antimicrobial, immunomodulatory, and antioxidant activities. Our findings suggest that probiotic fermented whey-milk beverages may exert antidiabetic and antioxidant properties, being suggested La-5 or Bb-12 as probiotics and 15 days of storage.

RESUMO

Minas frescal cheese is extremely popular in Brazil, with high perishability and acceptability. Among emerging technologies, ultrasound stands out for its satisfactory results regarding microbiological safety and technological and sensory aspects. The combined mild temperature application, called thermosonication, can generate even more promising results. In this study, a high-intensity ultrasound system combined with thermal heating (TS, thermosonication) was applied for the treatment of raw milk to produce Minas Frescal cheese. US energy was delivered to raw milk samples using a probe operating at a 20 kHz of frequency and nominal power of 160, 400, and 640 W. The TS system was compared with conventional pasteurization (HTST, high-temperature short-time pasteurization) at 72 to 75 °C and 15 s. Soft cheeses were prepared with different samples: (a) raw milk (control), b)conventionally pasteurized milk (HTST), and c) TS treat milk in different nominal power (TS160, TS400, and TS640). The produced cheeses were evaluated for microbiological behavior, rheology, color parameters, and bioactive compounds. TS treatment in milk resulted in higher microbial inactivation and stability during storage, improved color parameters (higher lightness (L*), and whiteness index (WI). TS treatment also showed a higher generation of bioactive compounds (higher antioxidant, and inhibitory activities of α-amylase, α-glucosidase, and angiotensin-converting enzymes) than HTST. The impact of TS on rheological properties was similar to HTST, resulting in more brittle and less firm products than the cheese produced with raw milk. The positive effects were more prominent using a nominal power of 400 W (TS400). Therefore, TS proved to be a promising process for processing milk for Minas Frescal cheese production.

RESUMO

The processing of high-protein vanilla-flavored milk was performed under different electric field strengths of ohmic heating (5.22 V/cm, OH6; 6.96 V/cm, OH8; 8.70 V/cm, OH10; 10.43 V/cm, OH12) to evaluate the energy consumption, processing parameters, and microbiological, rheological, and biological aspects, compared with the sample submitted to conventional pasteurization (PAST, 72 °C/15 s). All samples showed higher than 12 g/100 mL of protein, consisting of high-protein content products. In addition, Ohmic Heating (OH) generated lower energy expenditure and more significant microbial inactivation of lactic acid bacteria, molds and yeasts, total mesophiles, and psychotropics. Furthermore, OH at lower electric field strengths, mainly OH8, improved anti-diabetic, anti-oxidant, and anti-hypertensive activities and rheological properties, and resulted in lower hydroxymethylfurfural contents, and higher whey protein nitrogen index. The results suggest that OH is a technology that can be used in flavored milk with high-protein content, being recommended an electric field strength of 6.96 V/cm. However, more studies are necessary to evaluate the effect of OH on high-protein dairy products, mainly by studying other OH processing parameters.

RESUMO

Milk and dairy products present considerable socioeconomic importance but are also a regular pesticide residue contamination source, which is considered a worldwide public health concern and a major international trade issue. Thus, a literature review was conducted to assess pesticide residue levels in milk and dairy products, as well as the residue degradation capacity during its processing. Organochlorine, organophosphate, synthetic pyrethroid and/or triazine were found in fluid milk, powder products, yogurts, cheese, butter, and sour cream. Thermal processing reduced most residue levels, although some treatments increased total hexachlorocyclohexane and its isomers (α-, γ-, δ-, and ß-). Emerging non-thermal treatments presented promising results, but some by-products had higher toxicity than their precursors. Biodegradation by lactic acid bacteria were effective during yogurt and cheese fermentation. However, ß-hexachlorocyclohexane level seems to increase in yogurts containing Lactobacillus acidophilus and Bifidobacterium animalis subsp. lactis, while increase or maintenance of pesticide residue concentration was observed during coagulation and cheese maturation. Deep research is needed to understand the isomerization and degradation mechanisms after thermal, non-thermal, and fermentation processing. Emerging heat technology can be an excellent topic to be investigated for pesticide residues degradation in the future. These mitigation approaches can be a feasible future alternative to milk and dairy production.

RESUMO

The oral environment is an essential part of the human microbiome. The consumption of probiotic products may improve the oral microbiota and reduce the risk of diseases. This paper presents a bibliometric and critical review of randomized clinical trials (RCTs) that used probiotics to analyze oral parameters in humans. RCTs carried out with no age, gender, and ethnicity restrictions and published in the pre-COVID-19 period were included. Furthermore, the utilization of probiotic dairy products to improve oral health is discussed. The bibliometric review demonstrated that 'Microbiology,' 'Dental caries,' and 'Streptococcus mutants' were the most highlighted keywords. Furthermore, Sweden and India have the highest number of publications. The most prevalent outcomes were 'salivary parameters,' 'periodontal disease,' and 'dental caries.' The most used vehicles for probiotic administration were pharmaceutical formulas and dairy products. The administration of probiotic dairy products could modify the oral microbiota (reductions in S. mutans counts), influence the caries development and periodontal disease in children, adolescents, adults, and the elderly, and improve gingival health. The main probiotic dairy products investigated were milk, fermented milk, yogurt, kefir, curd, and cheese. Lacticaseibacillus paracasei SD1 was the most used probiotic culture. The studies demonstrated that the probiotic effect lasted 2-4 weeks after discontinuing consumption. However, the results depended on the subject type, study design, probiotic strain and concentration, and dairy product type. In conclusion, probiotic dairy products are promising alternatives to improve oral health.

RESUMO

The trends related to ohmic heating technology in food processing were evaluated using bibliometric analysis based on the scientific literature published in the last decade. Publications from Turkey, Brazil, and Iran represent 32% of all publications. Most studies have targeted the definition of the best combinations of operational parameters for application in different food matrices and their possible effects on the food properties. In addition, a tendency to use ohmic heating as an alternative technology for pasteurization was observed. Future studies should develop mathematical models that evaluate process parameters and food characteristics in the inactivation of microorganisms and enzymes and maintenance of bioactive compounds, the study of the non-thermal effect of electromagnetic waves on the food quality, the evaluation of the processing conditions and food physicochemical properties in the electrode corrosion and migration of metal ions to the treated food, and improvements of homogeneity during processing. This study was the first to perform a bibliometric analysis based on scientific literature concerning ohmic heating in food processing and presented the challenges, future trends, and evolution of scientific research.

RESUMO

The effects of thermosonication processing (TS, 90 °C, ultrasound powers of 200, 400, and 600 W) on the quality parameters of Jamun fruit dairy dessert compared to conventional heating processing (high-temperature short time, (HTST), 90 °C/20 s) were evaluated. Microbiological inactivation and stability, rheological parameters, physical properties, volatile and fatty acid profiles, and bioactive compounds were assessed. TS provided more significant microbial inactivation (1 log CFU mL-1) and higher microbial stability during storage (21 days) than HTST, with 3, 2, and 2.8 log CFU mL-1 lower counts for yeasts and molds, aerobic mesophilic bacteria, and lactic acid bacteria, respectively. In addition, TS-treated samples showed higher anti-hypertensive (>39%), antioxidant (>33%), and anti-diabetic (>27%) activities, a higher concentration of phenolic compounds (>22%), preservation of anthocyanins, and better digestibility due to the smaller fat droplet size (observed by confocal laser scanning microscopy). Furthermore, lower TS powers (200 W) improved the fatty acid (higher monounsaturated and polyunsaturated fatty acid contents, 52.78 and 132.24%) and volatile (higher number of terpenes, n = 5) profiles and decreased the atherogenic index. On the other hand, higher TS powers (600 W) maintained the rheological parameters of the control product and contributed more significantly to the functional properties of the products (antioxidant, anti-hypertensive, and anti-diabetic). In conclusion, TS proved to be efficient in treating Jamun fruit dairy dessert, opening space for new studies to define process parameters and expand TS application in other food matrices.

RESUMO

In recent years, many studies have been conducted to develop functional meat products, focusing on strategies to maximize health-promoting compounds and reduce the presence of those that may cause negative impacts on the consumer's health. As such, the use of prebiotic, probiotic, and synbiotic agents in meat products has grown considerably. In addition, the use of new generation probiotics in meat products is a novel field that can be explored. With the most recent paraprobiotics/postbiotics update, several components could be tested in meat products. Some interventional studies using meat products added with biotic agents have shown great potential as functional foods by reducing the formation of nitrous compounds in the gut and improving the functionality of the gut microbiota. Although there are few studies focusing on synbiotic meat products, the results are also very promising in this field. As such, this review seeks to describe how probiotics, prebiotics, paraprobiotics and postbiotics can be employed in meat products to give them functional properties, as well as some of the major issues that may arise when using these agents.

RESUMO

Reducing the fat content of processed meat products has become necessary due to consumer-driven demand for healthier foods. In this sense, this study aimed to characterize chicken mortadella with total and partial replacement of chicken skin by green banana biomass (GBB). Five treatments (with two repetitions each and weighing 400 g) were prepared: F0 (control treatment formulated with 100% chicken skin), F1, F2, F3, and F4 (25, 50, 75, and 100% of chicken skin replacement by GBB, respectively). Samples were characterized according to physicochemical composition - approximate composition, energy value, pH, water activity (Aw), emulsion stability (ES), water-holding capacity (WHC), instrumental color (L*, a* and b*), instrumental texture, fatty acid profile, and microstructure) - nutritional quality and sensory properties (dynamic profiling by Temporal Check-all-that-apply and acceptance). The replacement of 100% chicken skin by GBB increased the WHC of mortadella and did not affect the ES in all formulations. The addition of GBB did not affect the typical mortadella flavor of the samples, and the dominance of the flavor was directed towards the fibrous and fat flavor attributes. In addition, all formulations had acceptance scores above 6.5. Based on the results, replacement up to 100% of chicken skin with GBB is possible and obtains a healthier emulsified meat product with good sensory acceptance.

RESUMO

Freeze concentration technology is applied to concentrate liquid foods at low temperatures, thus separating pure ice crystals from the final concentrate solution. This method is an interesting alternative to concentrate food with high water levels and significant nutritional value such as dairy products, since several bioactive compounds are reduced when exposed to elevated temperatures. Considered that, this technique may be a great alternative to concentrating and maintaining both nutritional and sensory characteristics of liquid foods. The present review aims to introduce freeze concentration procedures as an eligible choice for conserving dairy products', also addressing its effects on the dairy matrix. PRACTICAL APPLICATION: This study reports the main techniques of freeze concentration applications in dairy products, to be used both on an industrial and laboratory scale, aiming to improve the nutritional quality of the products obtained.

RESUMO

This study aimed to construct and validate a scale to evaluate the honey consumer perception. Furthermore, the impact of packaging design on honey's perceived quality and purchase intention was evaluated. Brazilian consumers (n = 343) answered the 21 self-descriptive statements of the scale using 7-point Likert scales. Furthermore, six different packages were presented, and the consumer perception (health, origin, safety, and taste) and purchase intention were evaluated using 5-point and 7-point Likert scales, respectively. Exploratory and confirmatory factor analyses and PLS path modeling were employed. The validated scale had 13 self-descriptive statements (indicators with factor loading higher than 0.4) and showed discriminant (heterotrait-monotrait ratio values < 0.85) and convergent validity (average variance extracted > 0.4) and adequate reliability (composite reliability > 0.70). The consumers associated honey with health properties and a safe product. Furthermore, they preferred honey purchased directly from producers due to its perceived quality (natural and pure). Honey packaged in glass jars with or without dipper was perceived as healthier, tastier, higher quality, and from trusted origin. Furthermore, glass jars were considered more practical and sustainable packages.
