Características físico-químicas e aceitação sensorial de salame tipo Italiano com adição de óleo de canola

The aim of this study was to evaluate the effects of partial pork fat replacement with emulsified canola oil in Italian-type salami. Three treatments were done: Control (100% pork fat, without fat replacement), T1 (15% pork fat was replaced by emulsified canola oil) and T2 (30% pork fat was replaced by emulsified oil canola). There were evaluated the salamis’ physicochemical characteristics (pH, water activity, weight loss, color and lipid oxidation) during the manufacture and storage period, and sensory evaluation after the manufacture process. The emulsified canola oil addition at different levels did not change the pH and color during the manufacture process, even though significant differences were found in these parameters during the storage period. The water activity did not differ significantly among the treatments. However, the treatments with emulsified canola oil added have a lower weight loss than the control. It was possible to observe an elevation on lipid oxidation values in the T2 during manufacture and storage periods, while in the T1, the values did not differ from the control at the end of manufactures and remained lower than the control during the storage period. Even more, the partial replacement of pork fat by emulsified canola oil did not affect the acceptance of the product for aroma, flavor, color, texture and visual appearance. Thus, the 15% pork fat replacement by emulsified canola oil in Italian-type salami is a viable alternative for the product diversification.O objetivo deste trabalho foi avaliar os efeitos da substituição parcial da gordura suína por emulsão contendo óleo de canola em salame tipo Italiano. Foram elaborados três tratamentos, entre eles: Controle (100% de gordura suína, sem substituição de gordura), T1 (15% da gordura suína foi substituída pela emulsão contendo óleo de canola) e T2 (30% da gordura suína foi substituída pela emulsão com óleo de canola). Foram avaliados as características físico-químicas dos salames (pH, atividade de água, perda de peso, cor e oxidação lipídica) durante o período de fabricação e armazenamento, além da avaliação sensorial após o término do processamento. A adição do óleo de canola emulsionado em diferentes concentrações não afetou os valores de pH e cor durante o período de processamento, apesar de diferenças significativas encontradas nesses parâmetros durante o tempo de estocagem. A atividade de água não diferiu significativamente entre os tratamentos. No entanto, os tratamentos com adição de óleo de canola tiveram menor perda de peso do que o controle. Foi possível observar a elevação nos valores de oxidação lipídica no T2 durante o processamento e armazenamento dos embutidos, enquanto que no T1 os valores não diferiram do Controle ao final do processamento e mantiveram-se mais baixos que o controle durante o tempo de estocagem. Ainda, a substituição parcial da gordura suína por óleo de canola emulsionado não afetou a aceitação do produto quanto ao aroma, sabor, cor, textura e aparência visual. Dessa forma, a substituição de 15% de gordura suína por emulsão contendo óleo de canola em salames é uma alternativa viável para a diversificação de produtos

Emprego de soro de leite líquido na elaboração de mortadela Employment of fluid whey in the elaboration of mortadela

No presente experimento, o objetivo foi verificar a possibilidade de incorporar soro de leite líquido em mortadela. A água empregada na elaboração da mortadela foi substituída nas proporções de 50, 75 e 100% por soro de leite líquido. Foram avaliadas as características sensoriais (cor, odor, sabor e textura), pH, coloração, estabilidade da emulsão da mortadela, assim como a percentagem de gordura e líquido, liberados após o tratamento térmico da emulsão da mortadela. A adição de soro de leite líquido não exerceu influência significativa nas características sensoriais, pH, coloração, estabilidade da emulsão e líquido liberado após o tratamento térmico das mortadelas. A substituição de 75 e 100% da água por soro de leite líquido, na elaboração da mortadela proporcionou menor percentual de gordura liberada após o tratamento térmico. Com base nos resultados obtidos, pode-se dizer que o soro líquido pode ser usado para substituir 100% do gelo usado na elaboração da mortadela, evitando que o soro excedente seja liberado no meio ambiente.<br>The objective of this paper was to verify the possibility of incorporating fluid whey in mortadela. The water employed in the elaboration of mortadela was replaced in the proportions of 50, 75 and 100% by fluid whey. Sensorial characteristics (color, odor, flavor and texture), pH, color, emulsion stability of mortadela were evaluated, as well as the percentage of fat and liquid released after thermal treatment of mortadela emulsion. The addition of fluid whey did not exert significant influence on the sensorial characteristics, pH, color, emulsion stability and liquid released after the thermal treatments in mortadela. Water substitutions of 75 and 100% by fluid whey in the elaboration of mortadela promoted a lower percentage of fat released after thermal treatment. Based on the obtained results it is clear that fluid whey can be used to substitute 100% of ice used in the elaboration of mortadela, thus avoiding that exceeding fluid whey be released in the environment

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P <.01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P =.15). Secondary end points did not differ between groups after follow-up. Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death. © 2019 The Author
