Abstract:The optimal formula and procession parameter of a new cool beverage containing Poria, Coix and other additives (the root of kudzu vine, liquorice, red dates, xanthan gum and sirup) were studied by one factor and orthogonal test. The results showed that the optimal formula of cool beverage contained 6% of the mixture of poria and the root of kudzu vine (1:0.6), 0.75% of Coix, 0.65% of liquorice, 1.25% red dates, 0.18% xanthan gum and 5.50% sirup. The best cooking time was determined as 30 min. Analysis of 100 mL product showed that the product contained 59.80 mg tuckahoe polysaccharide and, 45.00 mg flavone of the root of kudzu vine.
