摘  要:
采用搅拌球磨机对木薯淀粉进行机械活化,以活化60min的木薯淀粉为原料,NaOH为催化剂,ClCH2COOH为醚化剂干法制备羧甲基淀粉,对羧甲基淀粉的溶解度,糊的透明度、冻融稳定性、抗老化能力、抗生物降解能力及表观黏度等性质进行研究。结果表明:机械活化木薯淀粉羧甲基化产物的溶解度大、糊的透明度好、抗生物降解能力强、黏度高,有较好的冻融稳定性及抗老化能力。

摘  要:
Carboxymethyl starch was prepared by dry method from cassava starch that was mechanically activated for 60 min using a stirring-type ball mill as the starting material,NaOH as the catalyst and ClCH2COOH as the etherification agent.The solubility,transparency,frozen-thaw stability,anti-aging capability,anti-biodegradation capability and apparent viscosity of prepared carboxymethyl starch were investigated.Results indicated that carboxymethyl starch products from activated cassava starch exhibited high solubility,better transparency,strong anti-biodegradation capability,high apparent viscosity,excellent frozen-thaw stability and anti-aging capability.
