Abstract

Rural India has a wide variety of traditional foods with area and region-wise specialities. These can be classified broadly into four groups: i) Cereal based products such as papads, vermicelli, rice flakes are predominantly moisture sensitive, having lower and upper critical moisture contents. ii) Legume and nut based foods such as fried and spiced moongdhal, boondi and groundnut items like chikki, spice coated kernels are sensitive to oxygen and small changes in moisture contents. iii) Spices and spice-based products such as ground spices, spice blends, sauces and pickles are susceptible to loss of volatile and colour ingredients and have critical moisture level of 10 - 12 percent. iv) Sweets and savouries are based on jaggery and sugar, such as monda sweets like pinni, rewri, mysore pak. These are relished for good taste and texture and deteriorate rapidly above 86% relative humidity. Based on the above kinds of product deteriorative characteristics and also considering the moisture adsorption/desorption characteristics and shelf-life requirements, functional and economical packages for traditional foods have been designed and evaluated. While polyethylene and polypropylene films are adequate for specific products with short shelf-life requirements, better functional composite structures based on plain and metallised polyester, aluminium foil and polyamide based co-extruded films are suggested for their extended storage life. These aspects have been discussed.
