摘要: 本文主要研究应用复合纤维素酶处理沙菜(属于红藻纲Rhodophyta)藻体对卡拉胶产率和品质的影响。研究结果表明,酶处理能大幅度地提高沙菜卡拉胶的产率,但卡拉胶的凝胶强度略有下降,而对凝胶质的两个最主要指标———硬度和脆性影响不大,其最佳的酶处理条件为:酶用量为100μ/g、处理时间为80min、处理温度为46℃、加热提胶时间为60min。

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.
