This method detects and quantitates the common phenolic antioxidants: propyl gallate (PG), 2,4,5-trihydroxybutyrophenone (THBP), tert-butylhydroquinone (TBHQ), nordihydroguaiaraetic acid (NDGA), 2-and 3-tert-butyl-4-hydroxyanisole (BHA), 2,6-di-tert-butyl-4-hydroxymethylphenol (Ionox-100), and 2,6-di-tert-butyl-4-hydroxytoluene (BHT). Applicable to animal and vegetable fats, oils, lards, shortenings, as well as antioxidant concentrate dissolved in other solvents. Samples are first dissolved in hexane or 1:1 mixture of acetonitrile: 2-propanol. If the sample is soluble in hexane, the antioxidants are partitioned into acetonitrile, which in turn is concentrated and diluted with 2-propanol (isopropanol). If the sample is soluble in a 1:1 mixture of acetonitrile:2-propanol, the sample is diluted. Antioxidants are then separated and quantitated using reverse-phase gradient elution HPLC using ultraviolet detection at 280 nm.
Information Required by Submitter:
If available, please provide an estimate for the amount of each antioxidant in your sample.
If present in your sample, the final report will include ppm values for propyl gallate (PG), THBP, TBHQ, NDGA, BHA, and BHT.
