Item Equiparação de atividade de Programa de Iniciação Científica (PIBIC): relatório final sobre avaliação da Tecnologia do ultrassom sobre aspectos físicos, químicos e nutricionais de filés de tilápias do Nilo (Oreochromis niloticus)(2024-06-06) Silva, Eloá Dandara Carvalho da; Oliveira Filho, Paulo Roberto Campagnoli de; http://lattes.cnpq.br/8043850276929205; http://lattes.cnpq.br/2682308411839274Item Qualidade do queijo e leite de vacas recebendo dietas com substituição do concentrado convencional por farelo de glúten de milho(2023-09-15) Wanderley, Rebeca Rubeana Magalhães; Soares, Luciana Felizardo Pereira; Rocha, Laura Leandro da; http://lattes.cnpq.br/7226123934022759; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/9156969560979809The Northeastern dairy farming is characterized by the constant pursuit of technological improvements in order to optimize resources and achieve profitable results, especially when considering the adverse conditions of the semi-arid region of Pernambuco, such as the seasonality of food supply, high temperatures, and the distance from major grain distribution centers for animal production. In this perspective, the objective was to evaluate the effects of substituting soybean feed, wheat, and corn feed with corn gluten feed in diets containing Mexican Elephant Ear cactus forage on the physicochemical, microbiological, and sensory characteristics of pasteurized whole milk and cheese curd. Eight Holstein cows with a lactation period of 70 to 90 days, an average body weight of 500 kg, and a milk production of 20 kg per day were used and distributed in a double Latin square design (4x4), according to the following treatments: 100% conventional concentrate (CC); 66% CC + 33% corn gluten feed (CGF); 33% CC + 66% CGF; 100% CGF. Milk samples were collected at 6:00 AM and 3:30 PM during data collection days for subsequent pasteurization, physicochemical evaluation, cheese production for each treatment, microbiological analysis, and sensory evaluation. For physicochemical analysis, Dunnett's test was conducted at a 5% significance level, and for sensory analysis, the Friedman test was used. No effect (P>0.05) of CGF on the physicochemical variables of pasteurized milk was observed, despite the positive quadratic behavior for crude protein and decreasing linearity for acidity. The moisture content of the cheese curd was the only variable that differed (P<0.05), showing a negative quadratic effect, 60.09% and 58.38% for the treatments with 33% and 66% substitution with CGF, respectively. The cheese curd produced met the microbiological standards in current legislation. The sensory attributes that differed (P<0.05) were moisture and strange flavor. The highest purchase intention corresponded to the treatment with 33% substitution (P<0.0001). It is concluded that substituting conventional concentrate with corn gluten feed in the diets of lactating cows, despite not differing in the fat content of pasteurized milk and the yield of cheese curd, promotes higher profitability at substitution levels of 33% and 66% with CGF.Item Análise da percepção de qualidade do pão francês pelo consumidor da Região Metropolitana do Recife/PE(2023-09-21) Ponte, Felipe Barbosa; Siqueira, Leonardo Pereira de; http://lattes.cnpq.br/9772792357816313; http://lattes.cnpq.br/1451676076411667Item Aspectos do processamento e comércio de pescados em pontos da Região Metropolitana do Recife(2023-04-27) Oliveira, Rebeca Vicente; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/9947932091712775The fish commercialization has great relevance in the local economic scenario, including in the metropolitan area of Recife, as it is a coastal city surrounded by large rivers and the sea, which makes it possible to obtain \ generation of fish, also having a wide range of breeding and producers of this means of production in the surroundings areas. Such products are usually sold in supermarkets, fairs and public markets and may present different hygienic\sanitary conditions that directly interfere with the health of the consumer. In order to evaluate these conditions in the hygienic and sanitary scope, as well as the quality of the products made available to society as a whole, a bibliographic review was carried out using research and academic publications carried out in recent years as a theoretical basis, as a subsidy and framework for this production. The criteria taken into account were the handling, hygiene care of the product, storage location, treatment and organization of establishments that sell these fish.Item Análise das condições de comercialização de crustáceos e moluscos de mercados públicos e supermercados da cidade do Recife(2022-10-06) Cavalcanti Neto, José Bezerra; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/1168297384174902At the Metropolitan Region of Recife the commercialization of molluscs and crustaceans is quite frequent and it is concentrated at supermarkets, smal markets and public fairs. This work intends to acssess the hygienic-sanitary conditions and price progression of those establishments. Unscheduled visits were made in ten different locations during the months of July and September in order to collect informations. Among those visited, seven of them were within the requirements established by the legislation, but three made several mistakes regarding sanitary conditions, being two of them being totally careless in relation to the involved high hygiene practices, presenting food without refrigeration, with foreign matter inside the packaging, product deformed colours, and presence of odors that denoted the deterioration of the food sold. At the establishments that were in accordance with what the standards recommend, there has a greater volume of products offered and a greater security of finding the necessary quality to guarantee health and people's well-being. Regarding prices, most products did not change during the survey period, except for one that had an increase of 14%.Item Análise das condições de comercialização de peixes de mercados públicos e supermercados na Região Metropolitana do Recife(2022-10-06) Andrade, Bárbara Poliana Ramos de; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/9881569348491890The growth of the human population has led to the search for productive maximization in several food production chains. Among the proteins of animal origin fish have excellent biological value and are easily digested by the human body. On the other hand fish have biochemical characteristics that facilitate their colonization by microorganisms with pathogenic potential, thus making it necessary to adopt measures to combat the spread of Foodborne Diseases (DTA's). Seeking to verify the conditions of commercialization of fish in establishments at Metropolitan Region of Recife unscheduled visits were made between the months of July and September 2022, at 11 different market places. There, were carried out observing the practices related to the handling, storage and progression of fish. fish prices as well as the sanitary conditions of the environment where they were marketed. The places that were classified as fairs or public markets had the worst sanitary conditions, having several products with clear signs of deterioration, in addition to inappropriate environments for food handling. The establishments that were supermarkets met the legal requirements for the commercialization of fish, except in specific situations.Item Relatório de Estágio Supervisionado Obrigatório(2019-12-05) Pinto, Maysa Queiroz; Lima, Tayara Soares de; http://lattes.cnpq.br/3100045021780173; http://lattes.cnpq.br/8500329329793563
