Analysis for lipid antioxidant activity of polysaccharides from Pyracantha fortuneana
摘要
Abstract
The polysaccharides were extracted from Pyracantha fortuneana with ultrasonic-assisted.The product were precipitated with ethanol,then PS1 、PS2、PS3 were obtained,respectively.The content of extracts were determined using glucose as index.The polysaccharides were analyzed with spectrum.The inhibitory effect to oxidation rancidity of oils and fats were investigated,and compared with VE.The results showed that the yield rate of PS1,PS2,PS3 were 0.68％,0.82％,1.25％,respectively.Spectrum analysis showed that these polysaccharides were pyranose chain configuration.When the polysaccharides concentration was 0.3g/L,the antioxidant activity of PS3 was prominent than others.The protection rates of PS3 for rapeseed oil,olive oil,goose grease,chicken grease,beef tallow,lard fat were 69.38％,59.19％,56.55％,66.52％,53.72％ and 66.42％,respectively.The acid value reduction for rapeseed oil,olive oil,goose grease,chicken grease,beef tallow,lard fat were 0.96,0.89,0.84,0.95,0.81 and 0.91,respectively.The results showed that these polysaccharides exhibited excellent ability to protect oils and fats.Furthermore,the antioxidant activity increased with the increasing of the concentration of polysaccharides.关键词
