Desenvolvimento de bebida fermentada análoga a kombucha, à base de inflorescências de jambu (acmella oleracea), e monitoramento de compostos bioativos

Abstract

Kombucha is a fermented product that is increasingly expanding in relation to its consumption and the advancement of its research due to claims of its correlated health benefits, arising from its compounds generated in fermentation. Therefore, the following research aimed to corroborate these advances by developing an analogue to the fermented one using jambu (Acmella oleracea) as substrate, three formulations of the drink were developed in which in the first stage the pH values, total acidity were monitored for 7 days, total soluble solids, total and reducing sugars, antioxidant capacity, in addition to total phenolic compounds and flavonoids. After the product was ready, the same parameters, as in the first fermentation, were observed with the addition of volatile and fixed acidity, density, profile of phenolic compounds, microbiological and sensory analyses. The final products agreed with the regulated standard for kombuchas (IN 41 MAPA, Brazil), being microbiologically safe, and the formulation with 75% of jambu addition was the one with the highest sensorial preference as well as purchasing potential. In general, during the first fermentation, the formulation with 50% of jambu addition showed the best performance for phenolic compounds, flavonoids, and antioxidant capacity, requiring new future stability studies of these compounds to be available in ready-made products.
