中文摘要: 研究热烫和干燥温度(55℃~75℃)对淮山粉物理特性的影响。研究结果表明:热烫处理对淮山粉的色泽、持水性、冻融稳定性、表观形貌和黏度都有显著影响,对堆积密度、持油性和碘蓝值影响不显著。经过热烫后,淮山粉持水性、冻融稳定性均优于未热烫处理的淮山粉,而未热烫的淮山粉在色泽和表观形貌等方面优于经热烫的淮山粉,热烫处理的淮山粉则淮山细胞出现了明显的糊化破损。温度对色泽、溶解度、表观形貌和黏度影响较大。淮山粉溶解度随干燥温度的升高而增大,当温度为70℃时达到最大溶解度,随后淮山粉的溶解度降低。

Abstract:The effects of blanching and drying temperature(55℃-75℃)on the physical properties of Chineseyam flour were investigated.While blanching showed significant effects on color,water holding capacity,freeze-thaw stability,microstructure and viscosity of yam flours,It had no marked effects on other physical properties of yam flours.Flours with blanching had better water holding capacity and freeze-thaw stability than flours without blanching.However,flours without blanching had better color and microstructure than flours with blanching.Color attributes,solubility,microstructure and viscosity were all affected by drying temperature to different extents.
