| 摘 要： | 本文以不同加工程度鲜糙米为原料制备米粉,对不同等级鲜糙米米粉的基础营养品质、维生素、微量元素、直链淀粉、热特性、流变特性和感官品质进行比较。研究得到,除碳水化合物和微量元素Cr之外,随着加工程度的提高,胚芽保留率的降低,糙米基础营养价值损失严重。糙米制备的米粉脂肪含量和灰分含量是精白米粉的近3倍,胚芽米粉的蛋白质含量可达8.13 g/100 DM,且维生素B1和B3含量分别为133.74μg/100 DM和3.39 mg/100 DM,是精白米粉7.5倍和10.6倍。而加工程度较高的精白米粉和白米粉由于高直链淀粉含量(分别为24.35%和23.50%),在热特性和感官评价方面表现较好。综合比较得出,5分白米粉在食用特性和营养特性均品质突出,且Zn的含量最高,为18.65 mg/kg(DM);流变特性和溶解特性测定中,5分白米粉的表观粘度与精米系有相近的表现,米糊状态较好,适合开发辅食米粉产品。
