چکیده
|
This paper deals with the preparation and antioxidation of polysaccharide from porphyra haitanensis. the ratio of water to raw material,extraction temperature and extraction time were taken in sequence as independent variables in single factor test,and polysaccharide yield as response value. using box-benhnken central combination experimental design principles and response surface methodology,interactions of variables and their influence on polysaccharide yield of p. haitanensis were studied and the prediction model of quadratic polynomial regression equation was inferred by simulation,in which the optimum parameters for preparing polysaccharide from p. haitanensis were 88.4°c of extraction temperature,1.97 h of extraction time and 40:1 (ml/g) of ratio of water to raw material,and polysaccharide of 15.19 % in yield from p. haitanensis was verified after two parallel test. furthermore,the polysaccharide of p. haitanensis showed good antioxidant capacity which could be used as potential natural antioxidant products in food additives industries. © 2017,pakistan botanical society. all rights reserved.
