Biotransformation of Tropical Fruit By-Products for the Development of Kombucha Analogues with Antioxidant Potential.

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 and tamarind for the production of fermented beverages.

Experimental Approach: Physicochemical and microbiological parameters, total antioxidant capacity and fermentation kinetics were investigated during the first (at 0, 48, 72, 96 and 168 h) and second fermentation (at 0 and 24 h).
