摘　　要：报道了甲壳胺（ｃｈｉｔｏｓａｎ）及Ｎ－亚甲基甲壳胺（Ｎ－ｍｅｔｈｙｌｅｎｅｃｈｉｔｏｓａｎ）对贻贝酶解液中各种氨基酸吸附情况。在一定ｐＨ（６．０）及浓度（９４５ｍｇ／ｋｇ）下：（１）甲壳胺对贻贝酶解液中各种氨基酸均有吸附，其中，对Ｔｙｒ，Ｐｈｅ，Ｈｉｓ，Ａｒｇ，Ａｓｐ及Ｇｉｕ的吸附率较高；（２）Ｎ－亚甲基甲壳胺对贻贝酶解液中Ｈｉｓ，Ａｒｇ，Ｔｙｒ，Ｉｌｅｕ，Ｍｅｔ及Ｌｙｓ吸附率较高：（３）甲壳胺和Ｎ－亚甲基甲壳胺对贻贝酶解液中总氨基酸的吸附率分别为１２．９４％和１１．７０％。The absorption of chitosan(CHS)and N-methylenechitosan(NMCHS)to every kind of amino acids in the hydrolysis mussel liquor with protease was reported.At pH6.0 and the concentration of 945mg/kg of chitosan(1)Chitosan can adsorb everykind of amino acids,and the absorption rates of chitosan to Tryosine,Phenylatanine,Histidine,Arginine,Aspartic acids and Glutamic acid were high;(2)N-meth-ylenechitosan adsorb every kind of amino acids too,and the absorption rates toHistidine,Arginine,Tryosine,and Isoleusine Methionine and Lysine were high;(3)Thetotal absorption rates of chitosan and N-methylenechitosan to every kind of amino acidsin the hydrolysis mussel liquor with protease were 12.94% and 11.70%,respectively.
