Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a production line for a cereal nutrition pack and its preparation process. Background Technology

[0002] "Nutritional packs" are nutritional supplements made from soybeans, dairy products, and other food bases, with added micronutrients and other ingredients. Nutritional packs can provide the body with some of the high-quality protein needed in a diet, and are specifically developed and formulated according to the nutritional needs of different groups. As the products continue to improve, nutritional packs designed for the elderly will be further promoted and applied.

[0003] In the current technology, the production process of nutritional supplements mostly uses soybeans, dairy products and other similar ingredients as the main ingredients. The raw material composition is simple and the nutrients are limited, which cannot meet people's needs for a variety of nutrients. Furthermore, since nutritional supplements are added to the nutritional supplements, improper handling during processing or packaging can lead to excessive oxidation of the nutrients, which will affect the flavor and quality of the nutritional supplements and thus affect the consumer's experience.

[0004] Therefore, it is necessary to effectively control the oxidation of nutrients in nutritional packs during production, storage, and sales, and the resulting deterioration in flavor, in order to ensure that the nutritional packs are favored by customers. Summary of the Invention
