Abstract
A set of two experiments ware conducted in the laboratory of Post Harvest Technology, Department of Horticulture. Post Graduate Research Center and Department of Agriculture Microbiology, College of Agriculture, Rajendranagar, Hyderabad to study the preparation of vinegar from mango processing waste. Mango is one of the most important fruit crops of India and is processed in to various products. Peel and stones, which accounts for nearly 20-30 percent of the fruit, are the major waste materials available during mango processing. The fermentable sugars adhering to the fruit processing waste materials are ideal subtracts for fermentation. The mango peel wash and stone wash and peel + stone wash homogenized separately for the preparation of treatments. Initially, wine was prepared by inoculating mango peel wash, stone wash and peel + stone washings with the yeast. After adjusting the washes T.S.S to 18o Brix for Neelam and 20o Brix for Totapuri. when fermentation was completed wine was filtered after clarification. The wine prepared form these washings contain only three to four percent alcohol, which was fortified with alcohol to get five percent alcohol percent. The acetifying bacterial in the form of mother vinegar was added for vinegar production to the vinegar. After vinegar production with five percent acidity, spices like ginger, cinnamon and artificial mango flavour were added to vinegar in order to reduce non-enzymatic browning and flavour loss during storage. Utilization of reducing sugars and alcohol production increased as the fermentation progressed. Among all the washings peel wash was found to be effective in sugar utilization and alcohol production in Neelam. In Totapuri sugar utilization is more peel + stone wash and alcohol production is more in stone wash. The acidity increased and inversely pH decreased with advancement in fermentation and acidification. In case of Neelam, peel wash is having highest acidity and peel wash + artificial mango flavour is having lowest acidity. Where as in case of Totapuri stone wash is having highest acidity and stone wash + peel wash + artificial mango flavour has lowest Acidity. Initially the colour was same. After addition of spices cinnamon is having highest among all the treatments in both the verities. The overall acceptability was more in peel wash + stone wash + ginger in case of Totapuri, where as in Neelum the overall acceptability was more in peel wash + Cinnamon The product will add value to the waste of mango. The flavored vinegar was found to be qualitatively good and economically feasible.
