Effects of different particle size on physical and functional properties of Auricularia heimuer powder
摘要
Abstract
Auricularia heimuer powder with different particle size was prepared by crushing and sieving treatment,and its physical and functional properties were studied.The results showed that with the decrease of particle size,the dissolution of polysaccharides of A.heimuer powder increased from 4.29％to 22.62％.The angle of repose,the angle of slip,the water-holding capacity,the water solubility index,the expansion force and the chromaticity all showed an increasing trend,indicating that the fluidity of the powder was reduced and the hydration capacity was enhanced.The bulk density and tap density first increased and then decreased,reaching the highest levels of 0.68 g/mL and 0.88 g/mL respectively at 100 mesh.The reduction of particle size significantly improved the brightness of the powder surface.In addition,with the decrease of particle size,the adsorption capacity of A.heimuer powder was significantly enhanced,and the gastric environment was more conducive to the adsorption of nitrite,and the adsorption capacity increased from 565.12 μg/g to 703.19 μg/g.The intestinal environment was more conducive to the adsorption of cholesterol,and the adsorption capacity increased from 1.12 mg/g to 4.51 mg/g.The glucose adsorption capacity increased from 6.27 mg/g to 14.04 mg/g.The infrared spectroscopy showed that the internal structure of the powder was not damaged by the crushing process.This study provides reference material for the development of related products of A.heimuer powder.关键词
