Abstract

The present study was undertaken to know the effectiveness of tapioca starch films for storing of five different food materials (four different spices and tea granules). The net change in weight for non-hygroscopic items was recorded from gain of 0.38 % to loss of 3.74 %, after 168 days of storage at room condition. The starch films were stored at room temperature and refrigerated condition for six months and the total microbial count was calculated. The biodegradability of the films was determined by CO2 emission test. Starch film having starch 3 %, chitosan 1 % and glycerol 20 % was found to be the most susceptible to microbial contamination, which produced net 0.019 g carbon dioxide evolution per g film during 105 days of soil burial.
