Abstract

This study aimed to (1) determine the effect of ethanol addition and the fermentation period of pulp liquid by product of cocoa beans fermentation to the characteristics of the cocoa vinegar, and (2) determine the addition of ethanol and fermentation period to produce the characteristic cocoa vinegar of pulp liquid by product of fermentation best cocoa beans. The experiments in this study using a Split Plots design by treatment with the addition of ethanol into the main plot consisted of three plots namely 0%, 2,5% and 5% (v / v). Treatment of fermentation period is a sub plot that consists of 6 levels namely 0, 2, 4, 6, 8, 10 days. Pulp liquid fermentation period which by product of cocoa beansfermentation affect the levels of acetic acid, pH, and total dissolved solids of cocoa vinegar, meanwhile the interaction, period of fermentation and the addition of alcohol in pulp liquid byproduct of fermentation of cocoa beans affect the degree of acidity (pH) of cocoa vinegar. Characteristics of the best cocoa vinegar determined by treatment them with the addition of etanol by 5% and fermentation period for 10 days with high levels of acetic acid, pH, total dissolved solids, alcohol consistency, and total reducing sugar in a row was 2,86 (% w/w) , 3,67%, 5,25% brix, 0%, and 2,47%. Keywords: cocoa vinegar, cocoa, fermentation period, the addition of ethanol
