Comparison among Different Green Extraction Methods of Polyphenolic Compounds from Exhausted Olive Oil Pomace and the Bioactivity of the Extracts.

The use of by-products as a source of bioactive compounds with economic added value is one of the objectives of a circular economy. The olive oil industry is a source of olive pomace as a by-product. The olive pomace used in the present study was the exhausted olive pomace, which is the by-product generated from the air drying and subsequent hexane extraction of residual oil from the olive pomace. The objective was to extract bioactive compounds remaining in this by-product. Various types of green extraction were used in the present study: solvent extraction (water and hydroalcoholic); ultrasound-assisted extraction; Ultra-Turrax-assisted extraction; and enzyme-assisted extraction (cellulase; viscoenzyme). The phenolic profile of each extract was determined using HPLC-DAD and the total phenolic content (TPC) and antioxidant activity (ABTS, DPPH, and ORAC) were determined as well. The results showed significant differences in the yield of extraction among the different methods used, with the enzyme-assisted, with or without ultrasound, extraction presenting the highest values. The ultrasound-assisted hydroethanolic extraction (USAHE) was the method that resulted in the highest content of the identified phenolic compounds: 2.021 ± 0.29 mg hydroxytyrosol/100 mg extract, 0.987 ± 0.09 mg tyrosol/100 mg extract, and 0.121 ± 0.005 mg catechol/100 mg extract. The conventional extraction with water at 50 °C produced the best results for TPC and antioxidant activity of the extracts. The extracts from the USAHE were able to inhibit Gram-positive bacteria, especially Bacillus cereus, showing 67.2% inhibition at 3% extract concentration.

Recent Highlights in Sustainable Bio-Based Edible Films and Coatings for Fruit and Vegetable Applications.

The present review paper focuses on recent developments in edible films and coatings made of base compounds from biological sources, namely plants, animals, algae, and microorganisms. These sources include by-products, residues, and wastes from agro-food industries and sea products that contribute to sustainability concerns. Chitosan, derived from animal biological sources, such as crustacean exoskeletons, has been the most studied base compound over the past three years. Polysaccharides typically constitute no more than 3-5% of the film/coating base solution, with some exceptions, like Arabic gum. Proteins and lipids may be present in higher concentrations, such as zein and beeswax. This review also discusses the enrichment of these bio-based films and coatings with various functional and/or bioactive compounds to confer or enhance their functionalities, such as antimicrobial, antioxidant, and anti-enzymatic properties, as well as physical properties. Whenever possible, a comparative analysis among different formulations was performed. The results of the applications of these edible films and coatings to fruit and vegetable products are also described, including shelf life extension, inhibition of microbial growth, and prevention of oxidation. This review also explores novel types of packaging, such as active and intelligent packaging. The potential health benefits of edible films and coatings, as well as the biodegradability of films, are also discussed. Finally, this review addresses recent innovations in the edible films and coatings industry, including the use of nanotechnologies, aerogels, and probiotics, and provides future perspectives and the challenges that the sector is facing.

Valorisation of Micro/Nanoencapsulated Bioactive Compounds from Plant Sources for Food Applications Towards Sustainability.

The micro- and nanoencapsulation of bioactive compounds has resulted in a large improvement in the food, nutraceutical, pharmaceutical, and agriculture industries. These technologies serve, on one side, to protect, among others, vitamins, minerals, essential fatty acids, polyphenols, flavours, antimicrobials, colorants, and antioxidants, and, on the other hand, to control the release and assure the delivery of the bioactive compounds, targeting them to specific cells, tissues, or organs in the human body by improving their absorption/penetration through the gastrointestinal tract. The food industry has been applying nanotechnology in several ways to improve food texture, flavour, taste, nutrient bioavailability, and shelf life using nanostructures. The use of micro- and nanocapsules in food is an actual trend used mainly in the cereal, bakery, dairy, and beverage industries, as well as packaging and coating. The elaboration of bio capsules with high-value compounds from agro-industrial by-products is sustainable for the natural ecosystem and economically interesting from a circular economy perspective. This critical review presents the principal methodologies for performing micro- and nanoencapsulation, classifies them (top-down and/or bottom-up), and discusses the differences and advantages among them; the principal types of encapsulation systems; the natural plant sources, including agro-industrial by-products, of bioactive compounds with interest for the food industry to be encapsulated; the bioavailability of encapsulates; and the main techniques used to analyse micro- and nanocapsules. Research work on the use of encapsulated bioactive compounds, such as lycopene, hydroxytyrosol, and resveratrol, from agro-industrial by-products must be further reinforced, and it plays an important role, as it presents a high potential for the use of their antioxidant and/or antimicrobial activities in food applications and, therefore, in the food industry. The incorporation of these bioactive compounds in food is a challenge and must be evaluated, not only for their nutritional aspect, but also for the chemical safety of the ingredients. The potential use of these products is an available economical alternative towards a circular economy and, as a consequence, sustainability.

Rootstock Affects the Fruit Quality of 'Early Bigi' Sweet Cherries.

The cherry rootstock influences the performance of the scion cultivar. It has an effect on cherry fruit quality, tree growth, yield and yield efficiency and floral and foliar nutrition. In this work, the influence of Saint Lucie 64 and Maxma 60 rootstocks on the fruit quality traits of cv. Early Bigi was evaluated. For this, several parameters, namely fruit weight (FW) and size (FS), soluble solids content (SSC), pH, titratable acidity (TA), flesh firmness (FF), epidermis rupture force (ERF), color and sensory profile, were assessed. Results showed that the fruits from trees on Saint Lucie 64 presented higher FF and ERF values and, consequently, better texture. On the other hand, fruits from trees on Maxma 60 showed sweeter cherries (higher SSC). Moreover, these trees presented the darkest cherries (lower values of L*, a*, b*, C* and hue°) and the highest SSC. Therefore, although the trees on Saint Lucie 64 produced firmer cherries, it was those with the Maxma 60 rootstock that produced sweeter and darker fruits. In conclusion, both scion-rootstock combinations proved to be good options for the region of Resende.

Applying an Innovative Model of Disaster Resilience at the Neighborhood Level : The COPEWELL New York City Experience.

Community resilience is a community's ability to maintain functioning (ie, delivery of services) during and after a disaster event. The Composite of Post-Event Well-Being (COPEWELL) is a system dynamics model of community resilience that predicts a community's disaster-specific functioning over time. We explored COPEWELL's usefulness as a practice-based tool for understanding community resilience and to engage partners in identifying resilience-strengthening strategies. In 2014, along with academic partners, the New York City Department of Health and Mental Hygiene organized an interdisciplinary work group that used COPEWELL to advance cross-sector engagement, design approaches to understand and strengthen community resilience, and identify local data to explore COPEWELL implementation at neighborhood levels. The authors conducted participant interviews and collected shared experiences to capture information on lessons learned. The COPEWELL model led to an improved understanding of community resilience among agency members and community partners. Integration and enhanced alignment of efforts among preparedness, disaster resilience, and community development emerged. The work group identified strategies to strengthen resilience. Searches of neighborhood-level data sets and mapping helped prioritize communities that are vulnerable to disasters (eg, medically vulnerable, socially isolated, low income). These actions increased understanding of available data, identified data gaps, and generated ideas for future data collection. The COPEWELL model can be used to drive an understanding of resilience, identify key geographic areas at risk during and after a disaster, spur efforts to build on local metrics, and result in innovative interventions that integrate and align efforts among emergency preparedness, community development, and broader public health initiatives.

Phenolic composition and antioxidant properties of ex-situ conserved tomato (Solanum lycopersicum L.) germplasm.

Tomato (Solanum lycopersicum L.) local varieties represent a reservoir of genetic diversity for desirable quality traits. In this study, a representative collection of table tomato germplasm conserved ex-situ in the Portuguese Gene Bank was characterized for its polyphenols composition and antioxidant capacity. Phenolic acids, such as caffeic and p-coumaric acids bounded to a hexose and 5-O-caffeoylquinic acid, corresponded to 71-98% of the identified phenolic compounds; while the remaining fraction consisted of quercetin and kaempferol glycoside derivatives. Among the studied tomato accessions, it was possible to identify those that stand out for the analysed bioactive traits. These findings highlighted the interest of using Portuguese tomato germplasm in breeding programs or of reintroducing into cultivation these local varieties used for fresh consumption.

[City-laboratory: Campinas and yellow fever at the dawn of the Republican era]. / Cidade-laboratório: Campinas e a febre amarela na aurora republicana.

In the late nineteenth century, there were yellow fever epidemics in Campinas. Considered a seaside disease, the fever startled lay people and physicians. The scientific debate about the etiology of the disease left the domain of magazines and medical correspondence to orient political and sanitary actions. In order to combat the disease, the city began to resemble a laboratory and experienced its "era of sanitation and demolition," with victories over the ailment and inconvenience to the public. The State Sanitary Commission led by Emilio Ribas, aware of Finlay's Culicidae theory, rehearsed in Campinas what would happen with Oswaldo Cruz and Pereira Passos in Rio de Janeiro. The novelty of combating mosquitoes coexisted with age-old practices dear to miasmatic theory, such as disinfection.

No final do século XIX ocorreram epidemias de febre amarela em Campinas. Considerada doença litorânea, a febre assustou leigos e médicos. O debate científico sobre a etiologia da doença deixou revistas e correspondências médicas para orientar ações políticas e sanitárias. Visando combater a enfermidade, a cidade ganhou contornos de laboratório e vivenciou sua "era do saneamento e das demolições", com vitórias sobre o achaque e transtornos à população. A Comissão Sanitária Estadual comandada por Emílio Ribas, ciente da teoria culicidiana de Finlay, ensaiou em Campinas o que ocorreria no Rio de Janeiro de Oswaldo Cruz e Pereira Passos. A novidade do combate aos mosquitos conviveu com antigas práticas caras à teoria miasmática, como as desinfecções.

Policiais e populares: educadores, educandos e a higiene social / Police involvement in the moral education of the lower classes in 19th century at Campinas

O insalubre Largo do Jurumbeval, em Campinas, constituiu durante a segunda metade do século XIX importante espaço de trabalho, diversäo e moradia popular. A promíscua aglomeraçäo de pessoas: escravos, libertos, imigrantes e nacionais pobres, inquietava as autoridades que, por meio da açäo da polícia, procuravam limitar, controlar e ordenar os movimentos de pessoas vistas como perigosas à sociedade, por seu comportamento considerado imoral e escandaloso. Nessa tentativa de realizar uma higiene social, por vezes, a própria polícia acabava representando um papel ambíguo, ao praticar os mesmos atos que devia reprimir. Resgatar alguns momentos dessa "didática" policial na vida das classes populares constitui o objetivo deste artigo. (AU)
