Kemin Agri-Foods North America, located in Des Moines, Iowa has recently commenced production from a new plant designed to process and pack OroGLO natural pigmenter extracted from marigold petals and KemGLO red pigment from peppers. The plant materials are derived from approved and monitored farms in Southeast Asia including India and China where there is a well established history of marigold and pepper production.
Raw material is processed by extraction and purification and the oleoresins are stabilized before export. Each batch is subject to stringent quality control to insure potency and freedom from contaminants before shipment and after arrival at the Kemin plant. There are two manufacturing streams for dry and liquid product respectively. The new plant incorporates years of Kemin technology to produce a highly stable and bioavailable product. Product is stabilized to the correct pH and is then split into either the dry or liquid steams.
Product which is added to mixers in liquid form is titrated to correct concentration and is packaged in totes or made available for bulk truckload distribution. The dry product stream is processed and blended by mixing with a carrier to the correct consistency and xanthophyll content. Products are labeled as to composition and batch and are embargoed until quality control assays have been completed.
OroGLO dry has a xanthophyll concentration of 20g/kg and KemGLO dry assays at 5g/kg. Nutritionists use these values in their ingredient matrices to formulate diets to contain a predetermined level of dietary xanthophyll consistent with the desired level of yolk pigment.
