Abstract
Tomato is a major vegetable crop that achieved popularity over the last few decades. The fruits are richest source of lycopene with antioxidant activity and anti-carcinogenic properties and require extensive study on this molecule. Tomato has recorded highest postharvest losses of 12.4 per cent among all the major vegetables. Hence, utilization of this waste for the extraction of lycopene and its further use in drug preparations and fortification of beverages is of immense use in processing industries and also in reduction of environment pollution. Keeping in view of the above facts the present study was undertaken at College of Horticulture, Kolar.
The waste tomatoes were collected from Agriculture Produce Marketing Committee yard, Kolar. The least damaged fruits were selected from the lot and used for disinfection process. Out of those different disinfection methods used chlorine dioxide has recorded highest per cent of disinfection by controlling microbial population (i.e., 6.66 CFU count). The highest lycopene (44.46 mg 100g-1) was extracted with fruit treated cellulase enzyme at two per cent and incubated for 60 minutes at 45 °C. Bulk extracted lycopene was concentrated using rotary evaporator. The concentrated lycopene was used for encapsulation with carrier material viz. banana fruit powder and jack seed powder. The definite concentration of concentrated lycopene was encapsulated with carrier material with different ratio. At the end of storage study, maximum retention of lycopene (156.30 mg 100g-1) and antioxidant activity (115.53 mg 100g-1) was recorded in lycopene encapsulated with jack seed powder and there were no microbial growth during storage period.
