Abstract:
Carotenoids are groups of important bioactive compounds，which possess important physiological functions as antioxidant, anti-aging, and preventing cancer or cardiovascular disease. With the growing demand of natural Carotenoids, people focus on the pomace or some processing wastes, gradually. In consideration of comprehensive utilization of the waste from apricot wine fermentation- residues, the effect of organic solvents on carotenoids from apricot residues was researched in this paper. The experimental results showed that the best solvent was the mixture of absolute ethyl alcohol-acetone (3:7) and the optimal parameters were as follows: the Carotenoids were extracted at 55 ℃ for 120minutes, at the ratio between material and solvent of 1:15, operated twice totally. Under the conditions, the yield of Carotenoids from apricot skin residue could reach up to228.62 μg/g.
