Resumo: 	ABSTRACT The aim of this study was to optimize the encapsulation of lycopene using response surface methodology and to determine its stability. The lycopene was extracted from tomato processing industry waste. The extracted pigment was purified by crystallization method. The effect of different process parameters, viz, core to wall ratio, sucrose to gelatin and inlet temperature on encapsulation efficiency (EE) and encapsulation yield (EY) were studied. Structural study of encapsulated material was carried by using scanning electron microscope (SEM). The samples with and without encapsulation were stored under different conditions such as the presence and absence of air, sunlight, at room temperature and under refrigeration. Highest EE (92.6 ± 0.86) and EY (82.2 ± 0.95) were observed when the core to wall ratio was 1:4, sucrose to gelatin ratio was 7:3 and inlet temperature was 1800C. The SEM analysis showed the encapsulated lycopene was of "bee-net" shaped, whereas lycopene without encapsulation was like "saw dust". More than 90% retention was recorded in microencapsulated sample stored in all storage conditions, whereas sample without encapsulation showed less than 5% retention with sample storage conditions after 42 days of storage. The optimization and storage study would be helpful to the lycopene producer to improve storage stability.
