Cellulase Treatment Studies on Effe cts on Extraction Yield and Quality of Carrageenan

Abstract

Abstract: This paper mainly investigatedthe e ffect onextractionyieldandquality of carrageenanafterhypnea being treatedby multiple cellulase.The r esultshowedthatthe extractionyie ldofhypnea carrageenanwas promotedata great extent after being treatedby cellul ase;but the gel strength of carragee nan decreased slightly,and the effe cts on the two mainindexes of gel texturehardness andbrittleness were little.Andthe optimumconditions of treatmentwere as follows the dosage of cellulase was 100U /g,t he treated time by cellulase 80minut es,the treated temperature 46℃and t he extractedtime 60minutes.

Key words: Multiple cellulase , Hypnea , Carrageenan , Extracted ratio , Quality
