一. First, what is corn spray husk?
Corn spout bark is a corn by-product produced in the process of processing alcohol, starch, feed, etc., and is a form of corn spout. It is mainly corn husk and seed coat, containing cellulose, lignin, protein, amino acids, fats, minerals and other nutrients.
二, the characteristics and nutritional value of corn spray skin
Step 1: Characteristics
Corn spray husk is yellow or brown in appearance and has a high proportion of crushed materials. It has a strong taste and is rich in crude fiber, which is not easy to swallow and digest. Because it contains a certain amount of lignin, at the same time, it may also be affected by factors such as corn type, water and cleaning treatment during processing, resulting in odor, mildew and other problems.
三. Nutritional value
Although the taste of corn spray husk is poor, it has high nutritional value, especially it is rich in protein and amino acids. In addition, corn spray husks also contain rich trace elements and minerals, such as iron, manganese, zinc, etc., which play an important role in human health.
Third, the application of corn spray skin
At present, corn spray bark is mainly used as raw material for poultry, livestock and other feed. Because of the high content of cellulose and lignin, it needs special treatment to improve its feeding value and utilization efficiency. For example, corn spray husks can be used by mixing feed and silage to improve feed quality and production efficiency of poultry, livestock and other animals.
At the same time, corn spray husk can also be applied to biomass energy, environmental protection and other fields, becoming a new resource. By using biomass energy technology, corn spray husks can be transformed into high value-added products such as gas and liquid fuel. In the field of environmental protection, corn spray husks can be converted into organic fertilizers, biochar and other products through fermentation, anaerobic treatment, etc., to achieve the purpose of waste resources and sustainable utilization.
Fourth, the difference and connection with other corn by-products
Different from corn by-products such as corn starch and corn malt, corn spout bark mainly exists in the form of fragments, which has a great impact on equipment and processing production. In addition, corn spout bark has a poor taste and is not suitable for processing for human consumption. Byproducts such as corn starch and corn malt contain more nutrients such as carbohydrates and proteins and can be used as raw materials for human food processing.
However, there is also a connection between corn spray husks and other corn by-products, which are produced in corn processing and can be converted and utilized as feedstocks for each other. Therefore, how to rationally utilize and treat corn by-products is of great significance to improve the efficiency, resource utilization and environmental protection level of corn processing industry.
