Using a Infinity Supercritical 10L system, a 3.5 hour run on Annatto (Bixa orellana) seed was performed, to determine availability to extract orange red condiment/food coloring. The extract is used typically in food industry for coloring, and has a nutty, sweet, peppery flavor terpenes. The color from Annatto is derived from carotenoid pigments (bixin and norbixin) from reddish waxy coating on the seeds. Typical acquisition of this condiment/coloring is from grinding, or extraction using hot water, oil, or fat (lard), which is then added to the food. This extraction can be done by supercritical CO2, and by the spinning disc reactor (for large industrial continuous extraction). Annatto is considered to be exempt of certification by the United States Food and Drug Administration because it is considered a natural food dye (also consider spirolina as green/blue coloring).
The resulting liquid can be sold as an extract, or dehydrated for powder, or further refined with Fast Filter to remove wax, and sold as concentrated extract, or further post processed with a distillation system for isolate (medicinal or vapes).
