The nutraceutical industry has experienced strong growth in recent years, and FDA regulations have added more stringent requirements. Near-infrared Spectroscopy (NIRS) can differentiate between fish oil blends of similar composition and determine if each blend meets specifications. This technology is a faster alternative to conventional lab methods and therefore accelerates raw material inspection, process monitoring and final product control.
Method description
Introduction Near-infrared (NIR) spectroscopy has been successfully used for identification of several closely related fish oil blends, with measurements taking 30 seconds per sample. Some samples varied only in triglyceride concentration, while other blends contained different components. By developing a library of NIR spectral variation for each unique product and running samples against the database of libraries, identification of fish oil blends was effective by NIR to a high degree.
