1. the content of linoleic acid is higher. The content of linoleic acid in maize reaches 2%. It is the highest content in grain feed. If corn's ration is more than 50%, only corn can meet the requirement of linoleic acid in pig and chicken (1%).
2. Low protein content and poor quality. Maize protein content is about 8.6%, and amino acid imbalance, lysine, tryptophan and methionine content is insufficient.
3. About 80% of minerals and minerals exist in embryo, with little calcium content (0.02%) and 0.25% phosphorus, but about 63% of them are phytate phosphorus. The utilization rate of monogastric animals is very low. The content of other mineral elements is also low.
4. There are more vitamin E in fat-soluble vitamins, about 20 mg/kg. There are more carotene in yellow maize, and almost no vitamin D and K. Water-soluble vitamins contain more thiamine, less riboflavin and nicotinic acid, and nicotinic acid exists as a binding type.
5. The average lutein content in yellow maize is 22 mg/kg, which is one of the characteristics of yellow maize. It has important significance for the coloration of egg yolk, tibia and claws.
After continuous production and practice, the equipment of Corn Flake production has been improved continuously, the automation degree has been higher and higher, and the production process has changed greatly. The raw materials have been changed from corn kernels at the beginning to corn flour, the cooking method has been changed to the continuous use of twin screw extruder, and the granulation process has been completed once in the extruder. The product is more uniform and tastes better after pre-drying and pressing. Better. Higher baking temperature makes the flavor of the product more prominent. Advanced industrial equipment and production line formed the following production process of Jinan Dingrun breakfast cereal cornflakes production line:
Corn flour, sugar, salt and other nutrients mixed ingredients twin screw extrusion ripening cutting moulding pre-drying pressing high temperature baking cornflakes
