Corn can be eaten directly, corn is one of the most important food grains in the world. Corn as well as corn by-products stalks can be used as feed. Corn kernels are important industrial raw materials, can produce corn starch, corn germ oil, compared with other oils, corn oil has a higher nutritional value. The use of corn can also produce more than 99.5% purity of anhydrous ethanol, reducing CO and SO2 emissions, thereby improving the atmospheric environment.
I. What are the uses of corn
1, direct consumption
? At present, about one-third of the world's population to corn as the main food, corn is one of the world's most important food, of which 50% of the Asian food composition of corn, Africa accounted for 25%, Latin America accounted for 40%.
2, feed use
Corn is the king of feed. Corn by-product stalks can be made into silage; corn as the main component of the feed, every 2-3 kg can be exchanged for 1 kg of meat? About 65-70% of the world's corn is used as feed, and the use of corn in developed countries up to 80%, corn is an important basis for the development of animal husbandry.
3, processed products
Corn kernels are important industrial raw materials. Can produce corn starch, most of the world's starch is produced from corn, in developed countries, corn starch processing has developed into an important industrial production industry. Corn germ oil, compared with other oils, corn oil has a higher nutritional value, containing extremely rich in protein, minerals, lecithin, vitamin A, vitamin E, etc., oleic acid up to 30%, linoleic acid up to 57%.
4, applied to petrochemical
The use of corn can produce more than 99.5% purity of anhydrous ethanol, it will be mixed with gasoline in the right proportion, can make the gasoline more fully combustible, reduce the emission of pollutants CO and SO2, so as to improve the atmospheric environment.
Second, corn can be processed which products
1, corn can be processed into corn oil, corn pasta, corn protein drinks, corn rice cakes, corn peanut pancakes, corn syrup drinks, starch, ham and sausage products.
2, corn oil is one of the products of corn deep processing, China's corn oil content is generally in the 3.5% to 4% or so, foreign cultivated high oil content of corn oil content of up to 7.2% to 7.5%, China's cultivated high oil corn up to 8% to 10%. Corn oil produced during the deep processing of corn can be further processed into corn salad oil, which can add value to corn. Corn oil is a kind of edible health care vegetable oil worth promoting, its unsaturated fatty acid content of up to 85% or more, mainly oleic acid and linoleic acid, absorption of aluminum up to 97% or more, is a good functional health food.
