Abstract
Most of fruits and vegetables are available in some specific season and not in others. So techniques have been developed to preserve such seasonal foods intact for later use. Blending extracts of medicinal plants with Candelilla wax as edible coating has been experimented by different researchers. So in present study two medicinal plants were explored because of their reported antifungal activity. Aloe vera (A. vera) is one of the liliaceous plants that has been a commonly used in skin care and pharmaceutical products. A. vera can be a good choice in protecting and prolonging the shelf life of food products. Toona ciliata (T. ciliata) is a large deciduous tree. It has vast application for treatment of chronic dysentery, ulcer, fever and headache. In present work two protecting films are formulated by mixing the extracts of A. vera separately T. ciliata with naturally occurring edible candelilla wax obtained from E.antisyphilitica. This wax was applied on fresh fruits including Golden apples, banana and lemon to estimate the effect of wax for promoting the shelf life of fruits under room temperature at 25o C for about 10 days and analyzed after every 30 hours. To calculate the performance of edible coating different parameters were observed including skin appearance, pH and weight loss. Weight loss in apples coated with ECC ranged from 0.3%-1.9%, ECAV 0- 2.6% and ECTC 0.3-1.9%. In case of Banana weight loss reached to 22.7% in ECC, 19.5% in ECAV and 28% in ECTC. In lemon 18.3% in ECC, 28.9% in ECAV and 44.42% in ECTC. pH values were also determined in apples reached to 6.0 in ECC, 5.5 in ECAV and 5.0 in ECTC. In banana pH values of all films were reached to 6.3 and in lemon all films showed slight difference in pH value i-e 3.0, 2.8 and 2.9 respectively. Fruits were stored at room temperature only banana showed the fungal attack. This application is industrially as well as economically beneficial in terms of maintaining the nutritional quality and browning of skin.
