Baked grain refers to products made by baking, which are usually used as raw materials for baked goods such as bread, biscuits and cakes. In the process of making, flour, sugar, fat and other ingredients react chemically at high temperature, which makes food swell, become soft and give it a specific taste and fragrance.

Puffed cereal refers to cereal products processed by puffing technology, and common examples are popcorn, puffed cereal, corn flakes and so on. In the process of puffing, grain particles expand when heated to form a crisp structure, which is usually used as snacks or breakfast food.

Generally speaking, the difference between baked grain and puffed grain lies in their processing technology and the use of the final product.
