EXPERIMENTAL MODELING AND SIMULATION OF ORGANIC COATING OVER BANANA PEEL TO INCREASE SHELF LIFE BANANA

Abstract

Banana is highly perishable material and nearly 30-40% of banana grown in India get spoiled and causes growth of microorganism. Reason behind this decomposition is diffusion of various gases / organic liquids through the banana skin protecting the inner carnal. Once transport of molecules through banana skin is slowed down more resistive it will increase life of banana. Mostly different types of hygienic chemicals are treated on top of the skin and it stops diffusion of molecules. We come out with three different chemical solutions and treat ripe banana to estimate how life can be extended. Atmospheric oxygen is mainly responsible for banana ripening which comes in through banana thin porous reactive peel and reduce it's shelf life. Diffusion of this compound through flat virgin banana skin and treated (edible contained protective solutions) banana skins were tested. It is noted that (Aleo Vera based) selection as coating material can minimize the microbe growth. Concentration and flux distribution of oxygen through banana peel is studied with the help of simulation software which help in increasing shelf life of banana. The model showed wonderful prediction oxygen diffusion in porous banana peel.
