Internally Developed Method
Testing reports values for alpha, cis-beta, and trans-beta Carotene. Following enzymatic digestion designed for foods, the sample is homogenized with tetrahydrofuran in order to extract the carotenoids. The extract is filtered and quantitated using reverse phase HPLC with UV/Vis detection.
α and ß-carotenes are plant pigments. This method measures the quantity of fortified and natural-occurring α and ß-carotenes in food products. Carotenes and retinol can be added together (as IUs) for the NLEA nutrition label.
High salt content may interfere with the analysis.
