canna edulis ker and the Chinese yam, which are rich in
starch, are mixed and processed into composite
starch; the extraction rate of the starch is increased by adopting the process of
grinding after freeze-
drying; the product starch is pure in viscidity, strong in hygroscopic property, fine and smooth in texture, abundant in
nutrient, high in purity, and abundant in glossiness, and contains delicate fragrances of sweet-scented
osmanthus and mint, the nutrients are regularly and quantitatively absorbed by adding the product when the food is cooked, and the purple potatoes, the canna edulis ker and the Chinese yam starch can be used for warming the middle warmer and harmonizing the
