Monitor Antioxidant Additives in Foods, using HPLC (AOAC Method 983.15) or Capillary GC and a Supelco Reference Standards Kit
12 Aug 2015Antioxidants are added to foods and other products to prevent rancidity. Supelco offers an antioxidant standards kit containing all 9 antioxidants listed in Association of Official Analytical Chemists (AOAC) Official Method 983.15: Phenolic Antioxidants in Oils, Fats, and Butter Oil, plus ethoxyquin, an additional commonly used antioxidant. This application note explores the effectiveness and efficiency of Supelcosil LC-18 HPLC columns, under the conditions described in the AOAC method, of separating these compounds in a short time period.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Food AdditivesAntioxidant
