强化米生产中营养液制备及其吸附特性研究

Formulation Optimization of a Liquid Nutritional Supplement for the Production of Nutrition-fortified Rice and Its Adsorption Characteristics onto Rice

通过正交试验确定复合型营养强化液最佳配方,并对其附着效果进行研究,当添加量为海藻酸钠0.3g/100g米、阿拉伯胶0.1g/100g米、明胶0.15g/100g米、蔗糖脂肪酸酯0.1g/100g米、水30g/100g米时,强化米表面有光泽,营养素吸附率59.63%。

A liquid nutritional supplement was developed and used to spray rice,and nutritional-fortified rice was obtained after tempering and drying.The orthogonal array optimization demonstrated that the optimum formula for the nutritional supplement was composed of a mixture of sodium alginate 0.3 g,arabic gum 0.1 g,gelatin 0.15 g and sucrose ester 0.1 g dissolved in 30 g of water for spraying 100 g of rice.The nutritional-fortified rice produced using such a nutritional supplement exhibited a rich lustrous surface,with 59.63% nutrient adsorption ratio.
