Corn starch by-product corn syrup:
Corn syrup is a by-product of corn starch production. The manufacture of corn starch must be corn kernels first soaked in sulfite, soaking liquid concentration is made into a yellow-brown liquid, called corn syrup. Corn syrup is rich in soluble proteins, growth factors and some precursor substances, containing about 40% to 50% solid material. In the corn soaking process if there are lactic acid bacteria and yeast, it will improve the quality of corn syrup; if there are spoilage bacteria will reduce the quality of corn syrup. Corn syrup is a very common application of microbial growth of organic nitrogen sources, it can also promote the biosynthesis of antibiotics such as penicillin.
Corn starch by-product germ:
Corn embryo can be used to make corn oil. So it is said that corn embryo is a good source of oil. The highest content of corn embryo is fat, the whole corn kernel fat more than 80% contained in the corn embryo. Corn embryo contains about 40% of oil, 13% of protein and 12% of starch. The rest of the corn kernel contains very little fat. Corn germ oil can not only be refined into salad oil, margarine and other nutritious edible fats and oils, but also pigments, paints and soap industry of high-grade raw materials. The de-oiled cake meal is rich in protein and other nutrients, and can be used to make a variety of food nutritional supplements.
Corn starch by-products of corn fiber:
Corn fiber is an important by-product of corn starch, dried corn fiber is generally used as feed, can also be used for fermentation. The dried corn fiber is generally not reprocessed, and some corn starch factories just use a pulverizer to pulverize it for sale.
Corn starch by-products of protein:
Protein is an important by-product of corn starch, the protein content of up to 50% -70%, mainly as a raw material for the production of high-protein feeds, but also can be used for the production of alcohol-soluble proteins other industrial products.
