Effect of irradiation on shelf life of health mix

An experiment was conducted to study the effect of irradiation on Shelf life of health mix. Initially the health mixes were formulated by using ragi, foxtail and green gram in the different ratios. Among them, Health mix of ragi, foxtail and green gram in the ratio of 40:40:20 (T3) was selected because of its superiority over other formulations. Irradiation treatment up to 0.5 kGy was taken to increase the shelf life of selected formulation (T3), then mix was evaluated for the microbial analysis like total bacterial count (TBC), total mould count (TMC) and sensory analysis like mouth feel, taste, texture, aroma, appearance and overall acceptability etc was carried out of both irradiated as well as non-irradiated sample on 0th day, 30th day, and 60th day respectively. The results shows that TBC of irradiated formulation at 0th , 30th and 60th day was recorded less count( 3x10-3 ,5x10-3 , 8x 10-3 cfu) over non-irradiated formulation (0, 1x 10-2, 2x 10-2 cfu). TMC of non-irradiated sample shows 0, 2x 10-1, 3x 10-1 cfu where as irradiated formulation shows zero TMC at 0th, 30th and 60th days.
