Abstract:

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.

Key words: nutritional-fortified rice, liquid nutritional supplement, adsorption characteristics
