DOI: https://doi.org/10.3390/app10238546 Interpretive Summary: Bioactive compounds are present in many plant parts. Peanut skins have large amounts of these compounds. The past decade has produced a number of publications that discuss the discovery, amounts and reports of how these compounds display activity such as antioxidants, anti cancer and protection against other chronic diseases. This publication is a review of the literature which concentrates on the methods that are used to extract the bioactive compounds from peanut skins. Peanut skins are an agricultural and food processing waste product that contain these compounds which could have commercial value if they could be economically recovered. Technical Abstract: Peanut skins are a waste product of the peanut processing industry with little commercial value. They are also significant sources of the polyphenolic compounds that are noted for their bioactivity. The extraction procedures for these compounds range from simple single solvent extracts to sophisticated separation schemes to isolate and identify the large range of compounds present. To take advantage of the bioactivities attributed to the polyphenols present, a range of products both edible and nonedible containing peanut skin extracts have been developed. This review presents the range of studies to date that are dedicated to extracting these compounds from peanut skins and their various applications. |
