ABSTRACT

The effect of green house type solar dryer and cabinet type dryer used for tomato drying with pretreatment of preservatives. We can see that the microbial growth not detected in the starting 30 days but the highest microbial count is 4.67×105 of untreated samples (6mm) in aluminum foil package under green house type solar dryer and microbial growth 4.55×105 of untreated samples (6mm) in LDPE packaging under cabinet tray dryer (65 0C). These are samples packed in LDPE and aluminum foil packaging materials and stored at room temperature. All microorganisms have a defined temperature range in which they grow, with a minimum, maximum, and optimum. An understanding of the interplay between time, temperature, and other intrinsic and extrinsic factors is crucial to selecting the proper storage conditions for a food product.
