[0246] Table 1: Ingredients of Examples 1 to 4

[0247] Ingredients / g Example 1 Example 2 Example 3 Example 4 Maltodextrin dry process 0 270 450 570 Maltodextrin wet process 570 300 120 0 Whey Protein Concentrate 50 60 68 70 Microcrystalline Cellulose 7.67 7 8 8 Galactomannan 35 40 40 45 Inulin 25 27 30 30 Choline chloride 2 2 3 3 Potassium Citrate 5 10 12 15 Sodium Citrate 5 10 12 15 Salt 5 7 7 8 Complex trace minerals 6.8 6.8 6.8 6.8 Hydrogen Phosphate 2 2 3 3

[0248] Comparative Example 1: The compounded trace minerals in Example 4 were deleted, and other ingredients and production process remained unchanged to obtain nutritional powder.

[0249] Comparative Example 2: The oil in Example 4 was deleted, and an emulsifier (lecithin / monoglyceride / diglyceride) was used, while other ingredients and production process remained unchanged to obtain a nutritional powder.

[0250] Comparative Example 3: When mixing the powder with the remaining maltodextrin, wet mixing is adopted, and other production processes remain unchanged to obtain nutritional powder.

[0251] Table 2: Differences between Example 4 and Comparative Examples:

[0252] Nutritional Information Absorption efficiency Oil embedding rate Example 4 99.7％ 99.4％ 97.2％ Comparative Example 1 65.5％ 76.4％ 96.7％ Comparative Example 2 76.7％ 97.5％ 96.4％ Comparative Example 3 71.5％ 70.5％ 96.2％

[0253] It can be seen from Table 2 that in the absence of compound trace minerals, necessary trace elements will be lacking. Secondly, compound trace minerals can help vasodilation, thereby increasing absorption efficiency. Secondly, when emulsifiers are used instead of oils, they are mainly used to stabilize the emulsified system, but reduce nutritional costs. Secondly, the use of oils can also increase taste and satiety, and the use of emulsifiers, although they can help disperse fat-soluble vitamins, cannot effectively protect them and can easily cause vitamin damage. The use of comparative example 3 will increase production costs. Secondly, it will cause damage to some vitamins. In addition, Example 4 can also achieve a similar oil encapsulation rate by using less raw materials than comparative examples 1-3.

[0254] In summary, the purpose of the wet process of this product is mainly to make vegetable oil into fat powder through processes such as embedding and spray drying. In the wet process, the remaining nutrients except maltodextrin are added in the wet process part, among which protein can help to increase the embedding rate of fat. Vitamins and minerals are low in weight, and the added cost of adding them to the wet process is very small. Micronutrients such as vitamins and minerals are added to the wet part, and after dissolution, emulsification, homogenization, spray drying, etc., the content in the finished product is more uniform than that added by the dry method, and fat-soluble vitamins and water-soluble vitamins are added under nitrogen protection after emulsification. During the whole process, the content of each vitamin is relatively stable, and the loss rate is small. The process loss of vitamin A and vitamin D is about 10%, and there is no loss of other vitamins.

[0255] By combining the dry process with the wet process, certain nutrients are pre-mixed in a wet state and then combined with the dry-mixed nutrients, which significantly improves the mixing uniformity and avoids the problem of uneven mixing in the dry process. When adding water to dissolve, the dissolution speed is faster due to more uniform mixing, and the liquid stability after dissolution is better, which solves the problems of poor solubility and insufficient stability in the dry process. Secondly, compared with the traditional wet process, the dry-wet composite process may reduce the dependence on high-cost equipment, such as spray drying, thereby reducing the overall production cost.

[0256] By adding complex trace minerals and using magnesium sulfate, it helps vasodilation, and magnesium sulfate works together with calcium sulfate to help maintain bone strength and density. Secondly, the use of oils and fats provides the human body with essential fatty acids, and when used in combination with fat-soluble vitamins and water-soluble vitamins, it can help the human body absorb fat-soluble vitamins and water-soluble vitamins.
