Abstract:
The use of malted flour was done for the formulation of the RTC Upma premix. The treatment T2 was packed in two packaging material i.e aluminum bag and plastic bag to access the shelf life at different interval of time. The microbial load, peroxide value, titrable acidity and moisture were estimated at 0, 15, 30, 45, 60, 75 and 90 days after storage and were compared for the best packaging material with the acceptable limit given by BIS. On the basis of the result it was observed that the premix was not found safe to consume after 60 days hence, the shelf life of Upma mix was 60 days at ambient condition and the Al(Aluminum) packaging was found best and safe for packaging in comparison to PL(Plastic). The yeast and mold increased significantly with increase in time interval in both AL and PL packaging material. The coliform bacteria count also increased significantly with increase in time interval in both AL and PL packaging material, whereas, for peroxide value, titrable acidity and moisture content the product was found safe in AL packaging.
