Permeability of Aloe vera composite coatings and their effect on quality of peeled carrots

In this study, three different composite coatings having Aloe vera gel, viz. 5%, 10% and 15%, carboxymethyl cellulose, peanut oil and glycerol monostearate were prepared. The 15% composite coating had reduced O-2 and CO2 permeability as well as water vapour transmission rate and higher viscosity. A. vera composite coating was applied on uniform healthy peeled carrots and they were packed in polyethylene bags. Storage was done at room and refrigerated temperature. During storage, surface microflora increased while total soluble solids, total sugars and total carotenoids decreased. The peeled carrots coated with 15% composite coating were best in quality at both room and refrigerated temperatures respectively.
