Cream is added to coffee, tea and other drinks to make them smoother and thicker. It can be milk-containing or milk-free, so-called animals and plants. From beginning to end, its function has nothing to do with nutrition. It is inappropriate for some scholars to find fault with the milk word of cream and check its nutritional value. Cream is not a natural agricultural product, but a kind of artificially blended product, so the formula of each product may be similar, but no two products are exactly the same. The preparation method comprises adding oil, sugar and protein, emulsifying with water, and spray drying to obtain powder. It is an additive that makes drinks taste better, not a nutrient.
