摘要:

探讨阳离子Na+和Ca2+对大豆果胶类多糖(SPP)黏度的影响,结果表明:SPP在Na+和Ca2+存在情况下,特性黏度降低,在稀释区时,SPP受离子影响,分子链柔性提高,并且大豆果胶在研究范围内不同环境条件下均为刚性杆状构象。

关键词: 大豆果胶类多糖, 黏度, 临界线团交叠值, 半稀释区斜率, 构象

Abstract:

This study investigated the effects of sodium and calcium cations on the viscosity of soy pectic polysaccharide
(SPP). The inherent viscosity of SPP was decreased in the presence of Na+ or Ca2+. Both cations increased the molecular
flexibility of SPP chains in the dilution zone. Moreover, SPP had a rigid rod-like conformation under the conditions adopted
in the present study.

Key words: soy pectic polysaccharide, viscosity, critical coil overlap, slope of semi-dilute domain, conformation
