真空干燥条件对稻米食味品质的影响(Effect of Vacuum Drying Conditions on Brown Rice Taste Quality)
稻谷 真空干燥 食味品质
2009/11/24
通过食味仪测量糙米理化指标数据,借鉴精米模型,利用系数重估法得出糙米主要成分含量与食味值的关系式。采用二次正交旋转组合设计方案,在控制干燥时间直至稻谷含水率达15%左右的基础上,建立了糙米食味值的数学模型。研究表明, 干燥温度、初始含水率和真空度是影响稻米真空干燥食味品质的3个重要因素,对食味值的影响从大到小依次顺序为干燥温度、初始含水率、真空度,且前二者与食味值呈负相关,后者与之呈正相关。
