Kemin Patents Polyphenol Retention Technology

By , in PR PR Health on .

DES MOINES, Iowa, Dec. 21, 2017 — Kemin Industries was recently granted an additional patent that supports the technology behind its patented lines of spearmint, KI110 and KI42. The patented spearmint lines are used to develop the company's cognition-enhancing ingredient, Neumentix™ Phenolic Complex K110-42. The newest patent covers the unique drying process used to retain health-benefiting polyphenols from the harvested spearmint.

Naturally occurring polyphenols in KI110 and KI42 spearmint lines include rosmarinic, salvianolic and caftaric acids. Research shows these polyphenols may act as antioxidants to reduce oxidative stress, promote new neuron growth and protect nerve cells in the brain.1

Spearmint is a seasonal herb that retains high levels of moisture. To preserve perishable polyphenols in spearmint, post-harvest drying is required. However, aromatic herbs are especially sensitive to post-harvest processing, resulting in discoloration and decreased nutritional value. The patented drying process successfully minimizes moisture while preserving the nutritional value of the spearmint.

“Removing most of the water from the plant material without destroying the rosmarinic acid allows us to extract dried material when there's demand, so that customers receive product at the height of its nutritional value,” said Dr. John Greaves, Vice President of Specialty Crops at Kemin Industries. 

Once dried, polyphenols from the KI110 and KI42 spearmint lines are water extracted to produce Neumentix, which can be formulated into a variety of supplement or food applications.

Brad grew up in a small town in northern Iowa. He studied chemistry in college, graduated, and married his wife one month later. They were then blessed with two baby boys within the first four years of marriage. Having babies gave their family a desire to return to the old paths – to nourish their family with traditional, homegrown foods; rid their home of toxic chemicals and petroleum products; and give their boys a chance to know a simple, sustainable way of life. They are currently building a homestead from scratch on two little acres in central Texas. There’s a lot to be done to become somewhat self-sufficient, but they are debt-free and get to spend their days living this simple, good life together with their five young children.
