The technology of corn syrup is as follows: soak corn in 0. 1-0.2% sulfurous acid solution (0. 13% sulfurous acid solution is mostly used in China), and put it in a soaking tank at 45-50℃ for about 50 hours. In the process of soaking, the nutrients in corn penetrate into the water, most of which are the most abundant nutrients in corn. Some strains in corn decompose and utilize various nutrients in corn to hydrolyze protein into peptides and amino acids. Sugar water is hydrolyzed and fermented into a large amount of lactic acid, and the content of L- lactic acid is as high as 30% (calculated by dry powder), so the pH value of corn syrup is very low (3.5-4.5). The dry matter content of corn syrup is generally 45-55%. In the process of corn impregnation, corn syrup produced by manufacturers with good production technology will produce a large amount of lactic acid, which will increase the acidity of the impregnation solution, inhibit the growth of other miscellaneous bacteria, and transform protein in corn kernels into amino acid aqueous solution and dissolve it in the impregnation solution. The increase of impregnation acidity makes the inorganic salts contained in corn soluble. So as to improve that quality of corn steep liquor. This is why the content of lactic acid and inorganic salts in corn syrup is high. Never use corn syrup directly like molasses. Corn syrup goes bad easily and smells bad. The cause of diarrhea that people say is not toxins and sulfite. Our company has done a comprehensive test. Mycotoxin and sulfite are not the factors that cause diarrhea. The key is usage and dosage! Corn syrup was dehydrated by low-temperature spray to form corn syrup protein powder, which has the unique smell of baked cookies, golden color and shelf life of 18 months. After comprehensive testing, the amino acid content is about 30, among which 38 kinds of organic protein can be used, and 43 kinds of protein contain non-protein nitrogen. But the good thing in it is L- lactic acid, up to 30%. The total amount of inorganic salts also reached 10%- 15%. There are lactose, many unknown growth-promoting factors, water-soluble vitamins and lutein. The content of salt and lactic acid is very high, and improper use will definitely lead to diarrhea. It is recommended that you use corn syrup protein powder, and the amount of full-price pig feed should not exceed 3%. It is equivalent to adding 9 kilograms of lactic acid and 4 kilograms of salt.
