Corn, a common crop, can be mistaken for a wheat field by an unfamiliar person. However, the sweet taste of corn and the variety of ways it is cooked make it a star ingredient in the kitchen. For example, we can make corn into delicious corn burners, tortillas, etc. In addition, corn is one of the whole grains, and eating more corn is beneficial to the body.
In addition to being our daily food, corn can also be deeply processed into other forms of products such as corn oil, starch, etc. Today, let's take a closer look at the charm of corn deep processing.
The cornstarch industry originated in the early 18th century and developed rapidly in the 19th century. In developed countries such as Europe and the United States, the development of starch industry is more rapid. As a large agricultural country, China's abundant resources provide favorable conditions for the development of starch industry.
Starch has become the basic raw material of pharmaceutical, chemical, health, food and other industries. With the continuous progress of science and technology and the adjustment of industrial structure, the application field of starch is also expanding. The light chemical products produced by reprocessing corn starch as raw materials are increasingly welcomed by the market, and the demand is increasing year by year, and occupies an important position in the national economy.
So, what is the significance of corn deep processing?
As a high-yielding crop, corn contains a lot of nutrients such as starch, protein powder, fat, inorganic salts, and vitamins. These substances are deeply processed to produce many products. First of all, cornstarch can be obtained by processing. Starch is the main raw material that many industrial production are inseparable from, and it is widely used in medicine, food, textile, printing and dyeing, chemical industry, papermaking, packaging and other fields. The amount of starch used in the production of degradable plastics is also increasing. At the same time, through further deep processing of corn, many high value-added products can also be produced, such as xanthan gum, maltodextrin, pharmaceutical starch, industrial starch, protein powder, corn oil, etc.
In addition, corn husk residue and corn germ meal feed are also products of corn deep processing. Corn husk residue is a by-product of corn starch processing plants, mainly corn seed coat. Its nutrient composition is slightly different, the crude protein content is 7 14, and the crude fiber content is 6 16, which is similar to the nutrient energy value of wheat bran. It can be used as feed instead of wheat bran. The germ produced during the processing of starch or wet grinding corn can be refined to make embryo powder, which can be used as protein feed or as an additive to lysine and methionine.
After reading these contents, I believe that readers have a deeper understanding of the benefits of corn deep processing. After processing, corn can not only be used for our consumption, but also for use such as feed, which truly achieves multiple benefits with one stone.
