Corn is different from other crops. Other crops, such as potatoes, have simpler compositions and mainly produce commercial starch. Corn, however, has a complex composition and is rich in nutrients. Therefore, various by-products are often generated during the production of corn starch.

The main by-products of the corn starch production process are:

Germ: The germ can be used to make corn germ oil.
Fiber: Corn fiber can be used to manufacture feed and can also be used as biofuel.
Protein: Protein can be added to feed to make high-protein feed, and corn protein can also be extracted for use in food packaging films, adhesives, etc.
In addition, the corn starch production process produces by-products such as amino acids, vitamins, minerals, and lactic acid. These can be added to animal feed along with corn protein to improve feed nutrition, or used as organic fertilizers, microbial culture media, etc.

Our company (Beijing Liretec Technology Development Co., LTD.) has decades of corn starch production technology and can provide complete commercial corn starch production and by-product extraction lines. We welcome inquiries and visits for contact.
