Abstract: The present study was undertaken to see the effect of different packaging material on physico-chemical quality parameters of maize germ during storage.Maize germ is an enriched by product of starch processing industry and a copious source of oil of good quality. In the pursuance of the study, the germ was extracted at optimum parameter using laboratory size maize degermer machine (at PAU, Ludhiana). The germ was dried to the desired moisture content using mechanical drier and packed in LDPE, HDPE and plastic jar for 60 days under ambient conditions. Different quality parameters viz., color, moisture, fat, protein, fiber, free fatty acid (FFA) and titrable acidity (TA) were determined at regular interval of 15 days for 60 days of storage. Results showed that the maximum germ retained was on sieve size of 1.4 mm with 82.29% retention, average particle size of 1.85+.01 mm with uniformity index of 1.465: 8.514: 0.017. Statistical analysis showed that all the quality parameters increased significantly (P<0.05) with the increase in the storage period. Further, the moisture, fat, ash, FFA, Fiber increased significantly (P<0.05) whereas protein, fat, TA showed no significant difference (P<0.05) storage period for the combined effect of packaging material and storage period. It was observed that the maize germ stored in HDPE package was found best in quality followed by LDPE and Plastic jar.
