摘要

通过 Maillard 反应，β-红霉素与羧甲基葡聚糖（CMD）共轭，以改善其功能。β-红霉素-CMD 共轭物经透析纯化。通过 SDS-PAGE 与 CBB 和 PAS 染色确认了共轭作用。经 BCA 法和苯酚硫酸法确认，β-共赖氨酸-CMD 的组成为 β-共赖氨酸：CMD = 1:2.7（摩尔比）。与 CMD 共轭后，β-红景天素在 pH 2.0-7.0 范围内的溶解度大大提高。在 pH 值为 7 且有盐存在的情况下，与 CMD 共轭可改善 β-丛赖霉素的乳化性能。与 CMD 共轭可降低 β-共赖氨酸的免疫原性。本研究中采用的共轭方法可用于食品加工，因此具有重要价值。

Functional improvements in β-conglycinin by edible bioconjugation with carboxymethyl dextran.

β-Conglycinin was conjugated with carboxymethyl dextran (CMD) by the Maillard reaction to improve its function. The β-conglycinin-CMD conjugate was purified by dialysis. Conjugation was confirmed by SDS-PAGE with CBB and PAS staining. Composition of the β-conglycinin-CMD was β-conglycinin:CMD = 1:2.7 (molar ratio) which was confirmed by BCA method and phenol sulfuric acid method. Solubility of β-conglycinin in the range of pH 2.0-7.0 was much improved by conjugation with CMD. Emulsifying property of β-conglycinin at pH 7 and in presence of salt was improved by conjugation with CMD. Immunogenicity of β-conglycinin was reduced by conjugation with CMD. Conjugation method performed in this study was considered to be valuable in that it can be used in food processing.
