Until recently, the unusable okara was a significant waste problem for many soy milk production plants. Okara, the insoluble fiber that is removed from the raw soy Now, soy milk producers send the okara to a drying machine which takes the moisture out of the okara, transforming it into a high-fiber, high-protein animal feed. The dried okara is now sold to farmers for feed, thus eliminating a storage and waste problem at most soy milk plants. It has proven to be invaluable to farmers who raise organically fed animals because many soy milk producers only take in organically grown soybeans. Thus, the dried okara feed produced from these beans is considered organic and acceptable for feed.
