Studys on the Preparation of Powered Lycopehe Using Porous Starch and its Stability
Lycopene has superior physiological function and poor stability. The Research aimed to improve its stability in order to extend its application. In this research the lycopene was absorbed by porous starch and cross-linking porous starch, and factors that influence the stability of lycopene including temperature, optical fiber were studied. The results showed that rafter 120h in the conditions of different light resource (natural light, fluorescent lamp and darkroom) , the residual rates of crosslinking porous powder lycopene, porous starch powder lycopene and lycopene decreased by 44.69％, 27.89％, 13.49％;76.68％, 47.15％, 22.07％ and 81.31％, 65.15％, 31.74％. After 4h in the conditions of thermal (30℃, 60℃ and 90℃) , the residual rates of them decreased by 0, 7.36％, 63.28％;0, 5.58％, 74.37％ and 0, 19.04％, 81.55％. Compared with the original lycopene powder, the light stability and thermal stability had been improved. This research provided the reference to the application and storage of lycopene.
