Research background
In a country where millions of people have nutritional needs, innovative ways of producing food from commonly wasted agro-industrial by-products, can be an important alternative for the production of fermented beverages. In light of this, the aim of this study is to evaluate the potential of fruit by-products from acerola, guava...
A kombucha é uma bebida fermentada que tem como base o chá preto, verde ou oolong e para que o processo de fermentação ocorra é necessário a presença de uma cultura simbiótica de bactérias e leveduras, conhecida como SCOBY. Agregado a isto, o Brasil é considerado um dos maiores produtores de frutas do mundo, entretanto, cerca de 30 a 40% de toda a...
Abstract The elaboration of fruit blends added of functional components results in nutritionally enriched products. The purpose of this work was to evaluate the physicochemical, sensorial and rheological properties of cashew-apple and araça-boi beverages added with encapsulated omega-3 and stability during 120 days of storage. Juice formulations we...
This work aimed to study beverages' storage stability based on cashew apple pulp and honey during 120 days. Three formulations were prepared: F1 (75% of cashew apple pulp and 25% of honey; F2 (60% of cashew apple pulp and 40% of honey) and F3 (50% of cashew apple pulp and 50% of honey). The formulation F1 showed the highest content of ascorbic acid...
Foods rich in antioxidants play an essential role in the prevention of diseases. The present study compared contents of phenolics, vitamin C, anthocyanin and antioxidant activity of 11 fresh exotic fruits, cultivated in the northeastern part of Brazil. The antioxidant activities were evaluated using two antioxidant systems 2,2-diphenyl-1-picrylhydr...
The objective of this work was to study the stability of a beverage formulated with acerola fruit juice and green coconut water with added caffeine. The beverage was prepared with 25% acerola pulp, 75% green coconut water and sugar up to 12°Brix, and caffeine (125 mg L−1), heat processed at 90 °C for 30 s and packed in 250-mL glass bottles. Chemica...
Os sucos de frutas são importantes fontes de vitaminas, sais minerais, ácidos orgânicos e fibras, e incluídos na dieta da população ajudam a manter a saúde. Durante as etapas de processamento dos sucos, podem ocorrer modificações nos componentes dos frutos, afetando suas propriedades sensoriais e nutritivas. Estudos sobre os efeitos do processament...
The purpose of this work was to analyze commercial açaí pulp and to correlate the contribution of vitamin C, total carotenoids and phenolic compounds with the antioxidant activity of there products besides the examination of the standard related to the quality of the obtained products. Analysis were made with regard to pH, acidity total, soluble so...
Acerola is a fruit which is much appreciated due to its high vitamin C content. It also has a good source of carotenoids and anthocyanins and is industrialised as frozen pulp and processed as juice. Research on the effects of processing on the nutritional constituent of tropical juices is scarce. Often, only the loss of vitamin C is evaluated. The...
Quinze amostras de sucos de frutas, cinco de abacaxi, cinco de caju e cinco de maracujá, de cinco marcas diferentes, foram analisadas através dos parâmetros químicos, físico-químicos e microbiológicos. Todas as amostras estavam dentro dos limites estabelecidos pelas legislações brasileiras em vigor para os parâmetros químicos, físico-químicos e mic...

Sucos de acerola, goiaba e manga, de cinco marcas diferentes, foram avaliados por meio de análises químicas, físico-químicas e microbiológicas. Das amostras avaliadas, apenas três de goiaba estavam em desconformidade com os parâmetros químicos e físico-químicos de identidade e qualidade dos sucos integrais em pelo menos um item. Em relação às deter...
