【摘要】 作为魔芋葡甘聚糖超微粉碎机械力化学效应研究的一部分,研究了超微粉碎处理对魔芋粉比表面积、表观密度、流动性、色度、溶胀速度及溶胶黏度等一系列物理性质的影响。结果发现超微粉碎处理后随魔芋粉粒度的不断下降,粉的比表面积总体呈不断增大的趋势;表观密度总体呈下降趋势;粉的流动性逐渐下降;粉的色度不断改善;粉充分溶胀所需时间呈显著缩短趋势;溶胶表观黏度呈显著下降趋势。更多还原

【Abstract】 As one part of the study on ultrafine comminution and mechanochemical effects of konjac glucomannan,the effect of ultrafine comminution on a series of physical property of konjac glucomannan are reported in this paper.These physical properties include specific surface area,apparent density,fluidity,chroma,swelling speed and sol viscosity.Along with the micromation of particle size after the ultrafine comminution,the physical properties of the konjac flour exhibit the following change trend: specific surface area enlarged,apparent density diminished,fluidity weakened,chroma improved,swelling speed enhanced and sol apparent viscosity descended.更多还原
