Non-fermented and fermented jabuticaba (Myrciaria cauliflora Mart.) pomaces as valuable sources of functional ingredients.

Jabuticaba (Myrciaria cauliflora. Mart) is a highly perishable fruit native to Brazil, which is consumed both fresh and industrially processed in the form of juices, jams, wines and distilled liqueurs. This processing generates a large amount of waste by-products, which represent approximately 50% of the fruit weight. The by-products are of interest for obtaining valuable bioactive compounds that could be used as nutraceuticals or functional ingredients. In this study, fermented and non-fermented jabuticaba pomaces were studied regarding their hydrophilic and lipophilic compounds, as well as their antioxidant properties, including: soluble sugars, organic acids and tocopherols (using high performance liquid chromatography coupled to refraction index, diode array and fluorescence detector, respectively); phenolics and anthocyanins, (using liquid chromatography coupled to diode array detection, and mass spectrometry with electrospray ionization); and fatty acids (using gas-liquid chromatography with flame ionization detection). The analytical data demonstrated that jabuticaba pomaces are a rich source of bioactive compounds such as tocopherols, polyunsaturated fatty acids and phenolic compounds (namely hydrolyzable tannins and anthocyanins) with antioxidant potential. Therefore, jabuticaba pomace may have good potential as a functional ingredient in the fabrication of human foods and animal feed.

Caracterização e análise sensorial de biscoitos de polvilho elaborados com diferentes níveis de farelo de mandioca

This study evaluated the chemically composition, color, specific volume and acceptability of biscuits made with cassava bagasse dehydrated. Held prior to the dehydration of cassava bagasse, then prepared themselves for producing biscuits with concentrations of cassava bagasse from 0% (BP), 2% (BF2), 4% (BF4) 6% (BF6) and 8% (BF8), instead of cassava starch. Data were analyzed by analysis of variance, Tukey at 5% level of significance. The dietary fiber content and attributes of color (L*, a* b*) the biscuits increased with the addition of cassava bagasse dehydrated, the dietary fiber content ranged from 5.47g 100g-1 to 11.40g 100g-1 and the protein ranged from 6.66g 100g-1 to 7.26g 100g-1. In 100 g of biscuit with 8% of cassava bagasse dehydrated are met 20%, 32%, 26%, 38%, 79%, 16% and 20% of dietary reference intakes for calcium, copper, phosphorus, magnesium, manganese, potassium and zinc, respectively. The specific volume of biscuits decreased with the increase of cassava bagasse. The biscuits were good acceptance for appearance, flavor and texture. It is concluded that cassava biscuits made with cassava meal dehydrated form a product with good nutritional potential and good acceptability.

Objetivou-se com este trabalho avaliar as características químicas, cor, volume específico e aceitabilidade, de biscoitos elaborados com diferentes níveis de farelo de mandioca desidratado. Realizou-se previamente a desidratação do farelo de mandioca e, em seguida, elaboraram-se formulações de biscoitos com concentrações de farelo de mandioca de 0% (BP), 2% (BF2), 4% (BF4), 6% (BF6) e 8% (BF8), em substituição à fécula de mandioca. Os dados foram analisados por meio da análise de variância, teste de Tukey, em nível de 5% de significância. O teor de fibra alimentar e os atributos de cor (L*, a* e b*) dos biscoitos aumentaram significativamente com a adição do farelo de mandioca desidratado, o teor de fibra alimentar total variou de 5,47g 100g-1 a 11,40g 100g-1, o de proteínas variou de 6,66g 100g-1 a 7,26g 100g-1. Em 100g de biscoito de polvilho com 8% de farelo de mandioca, encontram-se atendidas 20%, 32%, 26%, 38%, 79%, 16% e 20% da ingestão dietética de referência para o cálcio, cobre, fósforo, magnésio, manganês, potássio e zinco, respectivamente. O volume específico dos biscoitos diminuiu com o aumento de farelo de mandioca. Os biscoitos apresentaram boa aceitabilidade para aparência, sabor e textura. Conclui-se que biscoitos de polvilho elaborados com farelo de mandioca desidratado constituem um produto com bom potencial nutricional e de boa aceitabilidade.
