S4CO2‘s Bio-Extraction ProcessTM (BEP) extracts and fractionates high value co-products from cold water shrimp by-products. Cold water shrimp by-products (shells, heads and tails) contain Omega-3 (DHA and EPA) and Astaxanthin which are high value ingredients in the nutraceutical and pharmaceutical industries.
Unlike conventional methods of Omega-3 polyunsaturated fatty acids (PUFA) extraction that utilize solvents, enzymes, urea complexation and molecular distillation, the BEP utilizes Supercritical CO2 Fluid Extraction (SFE) using carbon dioxide to produce cleaner, residue free, higher quality PUFA and Astaxanthin extracts.
Additional advantages of SFE include its tasteless, odorless, non-toxic, non-flammable and generally regarded as safe (GRAS) properties. These additional advantages are crucial as other suppliers of Omega-3 have had challenges in removing the fishy taste and smell from these oils, often accomplished through deodorization or encapsulation technologies. Furthermore, the oils used to provide Omega-3 fortification in foods and beverages must be fresher and with less oxidative waste because oxidation affects the smell and taste of the food, thus the advantages of SFE address these key food market demands.
