Resumo O doce de leite está entre os mais importantes doces consumidos na região do Mercosul, o que estimula o estudo de sua produção. Estudos recentes têm mostrado o interesse dos consumidores por alimentos mais saudáveis, demandando o presente estudo, que teve como objetivo desenvolver um doce de leite mais nutritivo, menos calórico e com maior rendimento, por meio da adição da biomassa de banana verde. Foram elaboradas cinco formulações de doce de leite, sendo quatro delas com adição de 5%, 10%, 15% e 20% de biomassa de banana verde e uma formulação padrão adicionada de 0,5% de amido comercial. As amostras foram avaliadas quanto à qualidade microbiológica e aos parâmetros físico-químico e sensorial. As diferentes formulações de doce de leite atenderam aos padrões microbiológicos e apresentaram aumento no rendimento com a adição da biomassa. Os resultados indicaram que o aumento da concentração de biomassa de banana verde aumentou o teor de umidade e diminuiu o teor de proteínas, lipídeos e calorias. Em relação à aceitabilidade, todas as amostras avaliadas apresentaram notas entre 7,23 e 8,72, ou seja, acima do mínimo aceitável, que é 6, para todos os atributos avaliados, indicando aceitação por parte dos julgadores. Todas as amostras apresentaram alto índice de intenção de compra, o que comprova os resultados encontrados de aceitabilidade. Observou-se que a utilização da biomassa de banana verde agregou características positivas ao produto, não influenciando na qualidade sensorial dos doces, e ainda melhorou seu rendimento, sendo uma boa opção para o desenvolvimento de produtos mais saudáveis.

Abstract The production and consumption of dulce de leche is one of the most important sweets in the Mercosul Region. However, recent studies have shown consumers’ interest for healthier food and no lactose products, hence creating a demand for this study aims to develop a more nutritional lactose-free dulce de leche with less calories and higher yielding by adding green banana biomass. Five lactose-free dulce de leche formulas have been elaborated in which four were added 5%, 10%, 15% and 20% of green banana biomass and one of them received a standard 0.5% of commercial starch addition. The samples were evaluated regarding its microbiological, physicochemical and sensorial quality. The different lactose-free dulce de leche formulas attended the microbiological standards and demonstrated an increased yield of the green banana biomass concentration. The results indicated that the rise of the green banana biomass concentration has increased moisture and decreased protein, lipids and calories levels. In regards of acceptance, all samples evaluated received grades between 7.23 to 8.72, that is, above 6 which is the minimum value accepted to all the evaluated attributes hence demonstrating the acceptance on behalf of evaluators. All samples presented high ratios of intent to purchase therefore confirming the acceptance results found. It has been observed that the use of green banana biomass aggregated positive characteristics to the product and did not influence the sensorial quality of the sweets, seeing that all of them could improve their yield and thus demonstrating to be a good option to the development of healthier products.

Resumo O consumo e, consequentemente, a produção de manteiga têm aumentado consideravelmente nos últimos anos. Para conhecer as manteigas comercializadas no Brasil, o estudo teve como objetivo analisar manteigas de origem brasileira, francesa, italiana e argentina. As amostras foram analisadas quanto ao teor de gordura, à umidade, ao extrato seco desengordurado e à acidez total, para comparação com a legislação brasileira. Também foram determinados os teores de cloretos, proteínas, cinzas, extrato seco total, atividade de água, cor e perfil lipídico. Em todas as análises, houve diferença significativa entre as amostras. Algumas amostras apresentaram desacordo com os requisitos de qualidade recomendados pela legislação brasileira para comercialização. Dez amostras não apresentaram o teor mínimo de gordura exigido, variando de 68,53% a 77,31% nas manteigas com sal e de 71,64% a 81,72% nas manteigas sem sal. Oito amostras estavam acima do permitido para umidade, variando de 17,05% a 20,28%, e todas estavam de acordo em relação à acidez. Os ácidos graxos predominantes em todas as amostras foram ácido mirístico (C14:0), ácido palmítico (C16:0), ácido esteárico (C18:0) e ácido oleico (C18:1n9). A influência regional, a raça do animal, o manejo dos animais e a época do ano em que o leite foi obtido para a produção das manteigas são considerados os principais motivos das diferenças físico-químicas encontradas entre as amostras.

Abstract The consumption and consequent production of butter has increased considerably in recent years. In order to know the butters sold in Brazil, the study aimed to analyze butters of Brazilian, French, Italian and Argentine origin. The samples were analyzed for fat content, moisture, Defatted Dry Extract (DDE), and total acidity for comparison with Brazilian legislation. The levels of chlorides, protein, ash, total dry extract, water activity, color and determination of the lipid profile were also determined. In all analyses, there was a statistically significant difference between the samples. Some samples showed disagreement with the quality requirements recommended in Brazilian legislation for commercialization. Indeed, 10 samples did not present the minimum fat content required, varying from 68.53% to 77.31% in butters with salt and from 71.64% to 81.72% in those without salt. Eight samples presented humidity levels above the legal recommendations, varying from 17.05% to 20.28%. All products were in agreement with acidity levels. The predominant fatty acids in all samples were myristic acid (C14: 0), palmitic acid (C16: 0), stearic acid (C18: 0) and oleic acid (C18: 1n9). The regional influence, breed and handling of the animals and season of the year in which the milk was obtained for butter production, were suggested to be the main reason for the physical-chemical difference found between the samples.

Abstract This study evaluated the effects of the addition of encapsulated Lactobacillus acidophilus and green banana biomass on the characteristics of requeijão cremoso processed cheese during the storage period of 45 days under refrigeration. The elaborated requeijões cremosos processed cheeses included addition of encapsulated Lactobacillus acidophilus as probiotic source, and green banana biomass as partial fat substitute, in a total of five treatments. Analyses were performed to evaluate probiotic viability, microbiological conditions, centesimal composition (moisture, fat, fat in dry extract, protein, ashes, carbohydrates), water activity, resistant starch, colour, texture, lipid profile and sensory acceptability. The addition of green banana biomass and fat reduction resulted in changes in the centesimal composition of the cheeses, with their moisture indexes increased and protein decreased, the F1 formulation was the only one that can be considered as low fat content and was also the one that presented higher moisture. The yellowish white coloration of the formulations was altered as a function of the composition as well as the texture parameters, F1 and F3 treatments presented the greatest changes. Probiotic viability did not differ between formulations, it only changed over time.
