The consumption of jabuticaba (Plinia cauliflora), a native Brazilian fruit, has shown promising results concerning some metabolic disorders. Therefore, studying it may aid in the development of products capable of preventing or delaying pathological conditions. The objective of the present study was to formulate a functional sourdough bread with the inclusion of jabuticaba peel flour (JPF) and to evaluate the effect on the postprandial response. The proximate composition of the JPF and bread, the stability of the antioxidant compounds after baking, and the functional activity in a clinical trial were carried out to develop the product and guarantee its quality. JPF increased the fiber content of the bread in comparison to the control from 1.0 g/100 g to 2.3–2.9 g/100 g. Also, the antioxidant capacity increased 1.35 to 3.53 times by adding JPF to the bread, as well as the total reducing capacity (1.56 to 2.67 times). The bread's shelf life was guaranteed for seven days. In the clinical trial, the consumption of control bread resulted in a glycemia peak at 30 min, remaining high until 45 min; for the JPF bread, we noticed a less prominent peak at 45 min and a decrease with less inflection until 180 min. The serum antioxidant capacity of the individuals increased after the 3 h. Although no statistical difference was observed between the groups in the satiety profile, JPF bread presented higher scores after 60 min. Furthermore, a lessened desire to eat other foods and hunger was observed after consuming JPF bread. The inclusion of JPF in the bread manufacturing process promoted a longer shelf life and increased nutritional quality. [ABSTRACT FROM AUTHOR]

Hygiene programs which comprise the cleaning and sanitization steps are part of the Good Hygiene Practices (GHP) and are considered essential to ensure food safety and quality. Inadequate hygiene practices may contribute to the occurrence of foodborne diseases, development of microbial resistance to sanitizers, and economic losses. In general, the sanitizer resistance is classified as intrinsic or acquired. The former is an inherent characteristic, naturally present in some microorganisms, whereas the latter is linked to genetic modifications that can occur at random or after continuous exposure to a nonnormal condition. The resistance mechanisms can involve changes in membrane permeability or in the efflux pump, and enzymatic activity. The efflux pump mechanism is the most elucidated in relation to the resistance caused by the use of different types of sanitizers. In addition, microbial resistance to sanitizers can also be favored in the presence of biofilms due to the protection given by the glycocalyx matrix and genetic changes. Therefore, this review aimed to show the main microbial resistance mechanisms to sanitizers, including genetic modifications, biofilm formation, and permeability barrier. [ABSTRACT FROM AUTHOR]

Orientador: Anderson de Souza Sant'Ana Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia de Alimentos Resumo: Diferentes micro-organismos podem estar relacionados à contaminação ou deterioração de alimentos, sendo Salmonella responsável por grande parte de surtos ocorridos. Surtos relacionados a diversos alimentos já foram relatados, mas sua ocorrência em alimentos de baixa atividade de água vem surpreendendo, uma vez que a redução deste fator é uma das medidas de controle utilizada pela indústria para evitar o desenvolvimento microbiano. O binômio tempo/temperatura também é um parâmetro importante para se evitar a multiplicação ou sobrevivência de micro-organismos, mas mudanças ocorridas na sua fisiologia e no comportamento genético, devido à sua adaptação ao ambiente, podem torna-los mais tolerantes a alguns tratamentos empregados na indústria de alimentos. Os testes desafio são adotados pela indústria como forma de avaliar o comportamento microbiano durante as etapas de processamento, bem como as formulações e condições de armazenamento e embalagem aplicadas ao produto. O desenvolvimento de um protocolo padrão para ser aplicado em alimentos com baixa atividade de água faz-se necessário, diante da possibilidade de sobrevivência de micro-organismos nestes produtos, incluindo cepas de Salmonella envolvidas em diversos surtos. Sendo assim, este trabalho avaliou a estabilidade de diferentes inóculos secos, armazenados em diferentes temperaturas ao longo do tempo, bem como a resistência de diferentes cepas de Salmonella sp. a dessecação, ao calor e sua capacidade de recuperação e crescimento após estresse. Para avaliar a estabilidade do inóculo seco, cinco cepas de diferentes sorotipos foram selecionadas de acordo com a sua associação a produtos de baixa aw e inoculadas em quatro veículos diferentes a fim de verificar a estabilidade em tempo e temperaturas pré-determinados. Já para os testes de resistência a dessecação, a aplicação de calor e a capacidade de recuperação e de crescimento após a reidratação de cepas estressadas foram utilizadas diferentes sorotipos isolados da cadeia produtiva de soja, um produto de baixa aw e com alto poder econômico. Para a estabilidade do inóculo seco, os resultados obtidos dos inóculos armazenados a 4 °C se mostraram mais estáveis, sendo a areia fina e a areia comum os melhores veículos dispersores, uma vez que o tempo para redução de 1 log ('delta') foi de 118 e 124 dias, respectivamente. A 25 °C somente o carbonato de cálcio foi estável em 150 dias, mas a partir do 30° dia a amostra apresentou crescimento fúngico o que inviabilizaria seu uso. Pela análise de variância observou-se que a sobrevivência no inóculo seco difere em relação ao veículo utilizado e ao tempo de armazenamento e que apesar de ocorrer uma variação na aw, esta não influencia na estabilidade do inóculo. Para as análises de resistência, os resultados demonstram que ela está relacionada ao sorotipo estudado e ao tempo de dessecação. A redução das células tende a aumentar, quando expostas por mais tempo. Em relação à capacidade de recuperação das células dessecadas após reidratação, células expostas por maior tempo ao estresse tiveram menor redução da população microbiana quantificada. Isso provavelmente esta relacionado com o tempo de adaptação da célula e consequentemente, a ativação dos mecanismos de resposta ao estresse. Na avaliação do crescimento das cepas após reidratação, o aumento da temperatura e do tempo de dessecação influencia diretamente na sobrevivência de Salmonella; quanto maior o tempo de exposição e a temperatura de dessecação avaliados, maior a sobrevivência. Por fim, na aplicação de calor, quanto maior a temperatura, maior a redução microbiana, mas nenhum dos binômios utilizados foi capaz de inativar completamente as células Abstract: Different microorganisms may be related to food contamination or deterioration, with Salmonella being responsible for most of the outbreaks. Outbreaks related to several foods have been reported, but their occurrence in foods with low water activity is surprising, since the reduction of this factor is one of the control measures used by the industry to avoid microbial development. The time / temperature binomial is also an important parameter to avoid the multiplication or survival of microorganisms, but changes in their physiology and genetic behavior due to their adaptation to the environment may make them more tolerant to some treatments employed In the food industry. The challenge tests are adopted by the industry as a way to evaluate the microbial behavior during the processing steps as well as the formulations and conditions of storage and packaging applied to the product. The development of a standard protocol to be applied in foods with low water activity is necessary in view of the possibility of microorganism survival in these products, including strains of Salmonella involved in several outbreaks. Thus, this work evaluated the stability of different dry inoculums, stored at different temperatures over time, as well as the resistance of different strains of Salmonella sp. Desiccation, heat and its capacity for recovery and growth after stress. To evaluate the stability of dry inoculum, five strains of different serotypes were selected according to their association to low aw products and inoculated into four different vehicles in order to verify stability at predetermined time and temperatures. In the tests of resistance to desiccation, the application of heat and the capacity of recovery and growth after the rehydration of stressed strains, different serotypes isolated from the soybean production chain, a product of low aw and with high economic power, were used. For the stability of the dry inoculum, the results obtained from the inoculums stored at 4 ° C were more stable, with fine sand and common sand being the best dispersing vehicles, since the time to reduce 1 log ('delta') was 118 and 124 days, respectively. At 25 ° C only calcium carbonate was stable in 150 days, but from the 30th day the sample showed fungal growth, which would make its use unfeasible. By the analysis of variance it was observed that the survival in the dry inoculum differs in relation to the vehicle used and the time of storage and that despite a variation in aw, it does not influence the stability of the inoculum. For resistance analyzes, the results demonstrate that it is related to the serotype studied and the time of desiccation. The reduction of the cells tends to increase when exposed for longer. Regarding the recovery capacity of desiccated cells after rehydration, cells exposed to stress for a longer time had a smaller reduction in the quantified microbial population. This is probably related to the adaptation time of the cell and, consequently, the activation of the mechanisms of response to stress. In the evaluation of the growth of the strains after rehydration, the increase in temperature and the time of desiccation directly influence the survival of Salmonella; The longer the exposure time and the desiccation temperature evaluated, the greater the survival. Finally, in the application of heat, the higher the temperature, the greater the microbial reduction, but none of the binomials used was able to completely inactivate the cells Mestrado Ciência de Alimentos Mestra em Ciência de Alimentos CNPQ 134472/2015-2

Different concentrations of water and ethanol (0:100, 25:75, 50:50, 75:25, and 100:0 v/v) were used in the extraction process and results showed that the hydroalcoholic extract (50:50 v/v) presented the highest total phenolics, ortho-diphenolics, Folin-Ciocalteu reducing capacity, FRAP, and Fe2+ chelating ability values. Flaxleaf fleabane leaves (FFL) contained 19.6 g/100 g of fibers and 26 g/100 g of proteins. Ellagic acid, procyanidin A2, caffeic, rosmarinic, gallic, and 2,5-dihydroxybenzoic acids were the main phenolics. This phenolic-rich extract inhibited the lipid oxidation of Wistar rat brain (IC50 = 863.0 mg GAE/L), inhibited a-glucosidase activity (IC50 = 435.4 µg/mL), protected human erythrocytes against mechanical hemolysis at different osmolarity conditions, and showed cytotoxic/antiproliferative effects against human ileocecal adenocarcinoma cells (HCT8; IC50 = 552.6 µg/mL) but no cytotoxicity toward noncancerous human lung fibroblast (IMR90). Overall, FFL showed potential to be explored by food companies to be a source of proteins, natural color substances, and phenolic compounds COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPES CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQ Fechado

Current scientific evidences on the relationship among food-health-disease have aroused worldwide interest in eating habits and healthy lifestyles. In this context, food with claims of functional and, or healthy properties, are conquering the market with releases of technological innovations. However, the industry faces challenges and difficulties to register this category of products. This work aimed to study the legislation and to build a simple model for the registration of dairy products claiming functional and or healthy properties. All steps to register an yogurt claiming functional and or healthy properties were explained through a practical example, employing fictitious company, product and labels. Were found 3 laws, 2 decrees, 4 administrative rules, 14 resolutions, 4 regulatory Instructions, 1 technical information, 1 guide and 1 circular letter, through a qualitative research documentary, that regulates the documents necessary to product register. From the legislation analysis, it was possible to show how the regulatory system is fragmented and the legislation sprayed due to the lack of specific information material and the need of qualified team of qualified professionals in the area of food, lawyers and marketing. As evidências científicas atuais sobre a relação existente entre alimentação-saúde-doença vêm despertando, em todo o mundo, o interesse por hábitos alimentares e estilos de vida saudáveis. Neste contexto, os alimentos com alegações de propriedade funcional e/ou de saúde estão conquistando o mercado com lançamentos de inovações tecnológicas. Existem, por parte das indústrias, desafios e dificuldades para registrar produtos desta categoria. Este trabalho aspirou a objetivos como pesquisar a legislação vigente e construir um “guia simplificado” para efetuar o registro de produto lácteo com alegação de propriedade funcional e/ou de saúde. Todas as etapas referentes ao registro de um iogurte com alegação de propriedade funcional e/ou de saúde foram explicitadas por meio de um exemplo prático, com criação da empresa, desenvolvimento de produto e rótulos fictícios. Por meio da pesquisa qualitativa documental foram encontrados: três leis, dois decretos, quatro portarias, quatorze resoluções, quatro instruções normativas, um informe técnico, um guia e um ofício circular. Através de análise da legislação vigente, evidenciou-se o quanto o sistema regulamentar atual é fragmentado. Concluiu-se que a legislação é “pulverizada”, que existe uma carência de material informativo específico e que, devido à complexidade na elaboração do processo para registrar um produto desta categoria, há a necessidade de uma equipe qualificada com profissionais habitados na área de alimentos, advogados e marketing.
