The studies on chitosan and Aloe vera gel coatings on biochemical changes and shelf life bell pepper (Capsicum annuum L.) were carried out with different combinations. Chitosan 1 per cent showed better shelf life with bio chemical parameters such as, titratable acidity and total antioxidant activity. It had highest titratable acidity content 0.22 per cent, antioxidant activity of 204.94 mg100g -1 at 9 days of storage, it was much higher than other treatments. Chitosan @ 1 and 2 per cent also showed best result on microbial inhibition. The TSS and ascorbic acid contents were found to be decreasing over storage period. The gel extract from leaves of Aloe vera @ 20% indicated its inhibitory action on bacterial and mycelial growth of during ambient storage.
