Abstract
The contents of the main nutrients and the juice yield of raspberry with two different maturity(maturity of 60% to 70% and 80% to 90%)were compared.The results showed that except for the water and pectin contents,the contents of total sugar,total acid,protein,vitamin C,total phenol,anthocyanins,ellagic acid,raspberry ketone and juice yield of 80% to 90% mature raspberry were higher than raspberry with maturity of 60% to 70%.The enzymolysis conditions were optimized by single factor and orthogonal experiment.The optimum conditions were determined as follows:pectase 0.05% (w/w),enzymolysis temperature 45 ℃,enzymolysis time 1.75 h.Under these conditions,the juice yield of raspberry was 80.63%.The conditions were reasonable and feasible,and it could be applied in raspberry juice making.关键词
