Cashew apple is a rich source of sugars and vitamins that is discarded as a waste during cashew nut processing. Cashew apples starts fermenting soon after the harvest and due to the presence of wide spectrum of polyphenols and tannins, change of colour of cashew apples lead to an unappealing marketability and storage stability. The present study is aimed to rapid identification of different spoilage yeasts and to identify them using MALDI-TOF Mass Spectroscopy. Spoilage yeasts like Candida krusei, C. tropicalis, Pichia norvegensis, Brettanomyces bruxellensis were the spoilage yeasts found to high confidence score values of 2.00 - 3.00 with high consistency
