摘要:

采用水提醇沉结合Sevag法脱蛋白,制备得到大粒车前子多糖(PLCP),然后考察多糖质量浓度及NaCl和CaCl2的添加对PLCP成胶性能的影响。结果表明:PLCP具有一定的成胶性能,增加多糖质量浓度能显著提高PLCP成胶性能;CaCl2在低浓度下便能提高PLCP的成胶性能,提高胶的热稳定性,而NaCl需要在较高浓度下才能促进PLCP的成胶性。

Abstract:

This study aimed at investigating gelling properties of crude polysaccharide from the seeds of Plantago asiatica L.
(PLCP), extracted with water and deproteinated by the Sevag method, as a function of polysaccharide concentration, NaCl
and CaCl2. PLCP could form gels and the ability of gel formation was remarkably enhanced at higher concentrations of
PLCP. The gel-forming ability and thermal stability of PLCP were increased at lowers concentrations of CaCl2. In contrast,
the gel-forming ability of PLCP was improved by NaCl only at higher concentrations.

Key words: Plantago asiatica L., polysaccharide, gelling properties
