Abstract
In this research, two kinds of wines were produced from mixture of pineapple and orange. The first type coded sample A was mixture of pineapple and orange fortified with sugar and honey syrup and the second, sample B was mixture of pineapple and orange fortified with sugar syrup. Both were sterilized using sodium meta-bisulphite before the addition of sugar and honey syrup and then inoculated with Saccharomyces cerevisiae strain collected from Nigerian Breweries Plc. Sample A was fermented for 9 days while sample B was fermented for 7 days. Organoleptic evaluation was carried out by 15 tasters to determine the quality of the wine. Before analysis, samples were filtered using a finning substance called Kielseguhr to remove the yeast and sediments after which they were allowed to age for 90days. The pH was monitored with pH meter while brix content, alcohol, colour, density, temperature, gravity were monitored with alcolyser machine. The pH of the must before pitching was 3.84, alcohol was 0.0%, brix was 11.050P while the specific gravity was 1.043. It was observed that there was fluctuation in the pH of both samples. Twenty four hours after fermentation, pH was reduced and later increased after 48hrs of fermentation and reduced again and on the 7th day increased, so at the end of fermentation for both samples, the pH value was more than the reading taken before inoculation. There was a gradual decrease and increase in reducing sugar and alcohol respectively for both samples. The sugar level of sample B was 0.070 P as against 11.050 P before the onset of fermentation and the alcoholic content after completion of the experiment was 5.12%. Sample A had brix of 5.050P as against 20.680P before the fermentation and alcohol of 7.35% after the 7th day. On the 9th day, the sugar has further decreased to 1.230 P and the alcohol content has increased to 9.82%.
