[Objectives] The research aimed to optimize extraction process of fucoidan from Sargassum fusiforme( FSF) and study its moisturizing performance. [Methods]Extracting condition of FSF by cellulase hydrolysis-ultrasonic assisted extraction method was optimized. The influences of solvent p H,enzyme dosage,extraction temperature,cellulose hydrolysis time,ultrasonication time,and the ratio of material to liquid on FSF were investigated by single factor and orthogonal experiments. [Results] The optimum extraction conditions were as followings:p H,4. 5; enzyme dosage,1%; extraction temperature,40℃; cellulose hydrolysis time,2 h; ultrasonic time,15 min; and the ratio of material to liquid,1∶ 10( g∶ m L). Under the optimal condition,the extraction yield of FSF was 8. 50%,RSD = 2. 74%. The short-time hygroscopicity( within 8 h) of crude extract of fucoidan from S. fusiforme( CEFSF) was better than glycerin,butanediol,and sodium alginate,and the moisture retention capacity of 1% CEFSF aqueous solution was better than 1% butanediol or 1% sodium alginate,and was equal to 5% glycerin under relative humidity of 43% and 81%. The determination results of skin moisture content and transepidermal water loss rate( TEWL)showed that: 5% CEFSF solution had good moisturizing effect. [Conclusions]The research could provide certain reference for deep development of S. fusiforme. 展开更多
