Is a product that has more nutritional value for health accepting after the trial of eating Rae-rai. The appropriate amount is 15 grams / 4 pieces. The appropriate price is 30 baht per 1 unit of packaging. Interested when the product is sold by the nutritional value of the basic recipe and the replacement recipe found that the composition in the inulin recipe, the substitution amount is 12.26 grams. Basic recipe moisture content is higher than the replacement recipe. Carbohydrate substitution recipe is higher than the basic recipe for the replacement recipe protein, which is higher than the basic recipe for the replacement recipe fat, which is higher than the basic recipe.
