ABSTRACT
Bebidas de origem vegetal vêm sendo estudadas como carreadoras de bactérias probióticas. Neste estudo objetivou-se elaborar duas bebidas mistas probióticas sabor goiaba e beterraba: BMAP (bebida mista à base de extrato de amendoim) e BMSP (à base de extrato de soja), que foram adicionadas de Lactobacillus rhamnosus GG. Avaliaram-se características sensoriais e microbiológicas das bebidas elaboradas e de uma bebida comercial a base de soja disponível no mercado (BSC). Verificou-se que, após o processamento, as bebidas BMAP, BMSP e a BSC apresentaram escores equivalentes a "gostei ligeiramente" e "gostei muito" para os atributos acidez, cor, sabor, aroma, textura e impressão global, e escores equivalentes a "talvez comprasse, talvez não comprasse" e "provavelmente compraria" na avaliação de intenção de compra, não havendo diferença das bebidas elaboradas para a comercial. Verificaram-se contagens de LGG superiores a 6,8 Log UFC. mL-1 nas bebidas. Todas as amostras estavam de acordo com os padrões microbiológicos exigidos pela legislação brasileira. As bebidas apresentam potencial de mercado e são consideradas um excelente veículo de LGG, além de uma nova opção de bebida funcional, não láctea, acessível à população.(AU)
Vegetable beverages have been studied as carriers of probiotic bacteria. The objective of this study was to elaborate two probiotic mixed beverages from guava and beet: BMAP (mixed beverage based on peanut extract) and BMSP (based on soy extract), which were added of Lactobacillus rhamnosus GG. Beverages from both matrices, without addition of probiotic, were denominated control (BMAC and BMSC). Sensory and microbiological characteristics of the elaborated beverages and a commercially available commercial soybean drink (BSC) were evaluated. It was verified that, after the processing, the BMAP, BMSP and BSC beverages presented "slightly liked" and "liked" scores for the attributes of acidity, color, flavor, aroma, texture and overall impression, and " maybe buy, maybe not buy "and" would probably buy "in the evaluation of the intention to buy, there being no difference of the beverages from to the commercial. LGG counts were above 6.8 Log UFC.mL-1 in the beverages. All samples were in accordance with the microbiological standards required by Brazilian legislation. The beverages present market potential and are considered a excellent vehicle of LGG and a new functional beverage option, not dairy, accessible to the population.
