Study of contaminants in lassi during storage

The trend of contaminants was studied in thermized Lassi during storage at different temperature. At 37±2°C, the count of SPC; yeast and mold in control increased from 230x10³: 10 to 400x10³: 14x10³ on 8^th day. On the same day, L₆₅ and L₇₀ (SPC; yeast and mold count) was only 27x10³: 500 and 10x10³: 40, respectively. At the day of termination, the count was found to be 40x10³: 3000 at 12^th day in case of Les and 48x10³: 5000 in L₇₀ on 16^th day. At refrigeration temperature (7±1°C), the count in control of SPC and yeast and mold were 310x10³: 5000 at the termination 15^thday, in L₆₅ it was 61x10³: 3000 on 30^th day; in L₇₀ the count was 45x10³: 2500 at the day termination (35^th day). Shelf life of product is directly effected by the undesirable organism present in lassi.
