Abstract:
Star fruit (Averrhoa carambola) is a nutritious tropical fruit. The aim of this study was to evaluate the production of a star fruit alcoholic fermented beverage utilizing a lyophilized commercial yeast (Saccharomyces cerevisiae). The study was conducted utilizing a 23 central composite design and the best conditions for the production were: initial soluble solids between 23.8 and 25 °Brix (g 100 g-1), initial pH between 4.8 and 5.0 and initial concentration of yeast between 1.6 and 2.5 g L-1. These conditions yielded a fermented drink with an alcohol content of 11.15 °GL (L 100 L-1), pH of 4.13-4.22, final yeast concentration of 89 g L-1 and fermented yield from 82 to 94 %. The fermented drink also presented low levels of total and volatile acidities.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
