Soursop (Annona muricata) vinegar production and its chemical compositions

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Vinegar is a liquid product that undergoes double fermentations, which are alcoholic and acetous fermentation. Sugar source was converted to ethanol in alcoholic fermentation, meanwhile ethanol was oxidised to acetic acid during acetous fermentation. Soursop (Annona muricata) was the starting material in this study, as it is easily available in Malaysia. Its highly aromatic, juicy and distinctive flavours enables the production of high quality vinegar. The objective of this research is to produce good quality soursop vinegar as an innovative method to preserve and utilise the soursop fruit in Malaysia and to determine its chemical compositions. It was found that the sugar content reduces over time, and it is inversely proportional to the ethanol concentration, due to the production of ethanol from sugar. Acetic acid was also found to increase with increasing fermentation time. pH showed no significant difference (p>0.05) in the reduction of sugar and the production of ethanol. However, significantly higher (p<0.05) production of acetic acid was observed at pH 5.0 and 5.5, compared to that at pH 4.5. There were no significant differences (p > 0.05) in Vitamin C contents in all soursop vinegar samples produced using different treatments.
