BioActives, LLC, Worcester, MA, has been issued patent No. 7,297,803, “Process for the preparation of lutein ester concentrate.” The patent describes a more cost-effective method for making lutein esters, which can lead to as much as a 50% cost savings for customers. The process allows the user to take advantage of a broader range of marigold oleoresins as a raw material, further lowering costs and making backward integration less difficult.
