Role of Ascorbic Acid in the Extraction and Quantification of Potato Polyphenol Oxidase Activity
Foods, 2021 The ability to accurately measure the activity of polyphenol oxidase (PPO) in complex matrices is essential. A problem encountered when using spectrophotometric methods is interference due to ascorbic acid (AA), often used as an enzyme “protecting agent”
