【 摘 要 】

Fucoxanthin is a carotenoid which occurs in marine brown algae and exerts multiple beneficial effects on human health, including the anti-diabetic, anti-obesity, anti-cancer, and antioxidant. The aim of this study was to maximise the extraction yield of fucoxanthin from laminaria japonica. By using microwave synergistic enzyme method, the extraction condition, namely the enzyme amount, complex enzyme ratio and microwave temperature were investigated and optimized with Response surface methodology (RSM) combined with Box- Behnken design (BBD). Microwave temperature was found to have the most significant effect on fucoxanthin extraction yield. With the optimized process parameter of extraction in this work, extraction yield of 0.443mgfucoxantun/gdry aigaewas obtained by 0.14g enzyme, complex enzyme ratio (pectinase : cellulase) of 1.12 and microwave temperature at 42.6°C . Therefore, with higher efficiency and low energy consumption system this method can be realized simpler.
