Now 21 patents cover manufacturing and identity testing of ENI's GreenGrown® material in the U.S., China, Germany, France, UK, Netherlands, Japan, Mexico, Australia, Brazil, Canada and Korea. In addition to covering manufacturing by fermentation, ENI has developed a method to discern shellfish-based from vegetable-based glucosamine.
