ABSTRACT
Wine can be produced from paw-paw carioca papaya. Ripe paw-paw were peeled, sliced and homogenized using a weaving blender to obtain 2.5 litres of paw-paw ‘MUST’ the fresh ‘must’ be added 0.49 litres of sodium metabisulphate to sterilize it, and get it ready for fermentation.
Fermentation was started by inoculating the ‘must’ with 15-25 hours grown yeast + culture (starter culture and primary fermentation), which will last for days and racked before secondary fermentation which lasted for 14 days. The young wine was racked OH from ‘less’ filtered and pasteurized. Maturation was allowed for 4 weeks only because of time constraints. Physicochemical of wine were carried out and determined to be PH-4 .0 specific gravity 1.0406, titrable acidity and alcoholic content " 80% (v/u).
Microbiological assay of the wine was carried out and the microbial load was total plate court 23 x 105 coliforms court 10 x 105 and yeast court 5 x 105. This shows that the wine was contaminated during processing and is not recommended for consumption. It is possible to produce accepted table wine from ripe paw-paw when the microbiology is under control.
