Abstract
Wine is an alcoholic beverage produced from juices of a variety of fruits by the fermentative action of microorganisms. There is a quest for alternative sources of must for wine fermentation, however, the proximate composition should be known to ascertain how nutritious it is. The study was thus aimed at determining the proximate composition of the wines fermented by Meyerozyma guilliermondii and Pichia guilliermondii. Two isolates identified as Meyerozyma guilliermondii strain 1621 and Pichia guilliermondii strain PAX-PAT 18S were used for the fermentation of the substrates obtained from a mixture of pineapple and banana pulp. The fermentation process was for 28 days, followed by a series of racking, clarification, and aging process which was for 2 months. The fermentation process comprised two setups: one was fermented by Meyerozyma guilliermondii strain 1621 and the other by Pichia guilliermondii strain PAX-PAT 18S. The process was monitored and the proximate analysis of the wines was ascertained. The wine produced by Meyerozyma guilliermondii strain 1621 had a moisture content of 82.56 %, ash content of 1.41 %, fat content of 0.08 %, protein content of 1.43%, and carbohydrate content of 9.77%. The wine produced by Pichia guilliermondii strain PAX-PAT 18S had a moisture content of 79.51%, ash content of 1.19%, fat content of 0.15%, protein content of 0.49%, and carbohydrate content of 10.49%. Although this study is not exhaustive, it shows that wines with good nutritional composition can be successfully produced using Meyerozyma guilliermondii strain 1621 and Pichia guilliermondii strain PAX-PAT 18S.
