Potato peel (PP) is a major agricultural food by-product derived from potato processing. However, up to now, its green value-added is a biological resource as antioxidant polyphenols. The research is limited to the extraction process of water / ethanol based solvent, and other ecological and friendly methods are lacking. Hydroxypropyl beta cyclodextrin (HP - β - CD) is a hydroxyl alkyl derivative of β - cyclodextrin. The extract made from Hydroxypropyl Betadex is particularly advantageous in food and / or cosmetics without additional energy and time consumption. It simplifies the downstream steps of the purification of the extract, and can be effectively applied to food antioxidants / antimicrobial agents and / or cosmetic ingredients. This method provides a broad prospect for large-scale application of polypropylene as a rich and low-cost biological resource for a variety of phenolic phytochemicals.

After the initial determination to determine the optimal concentration of Hydroxypropyl Betadex, this concentration will provide higher polyphenol extraction rate. The optimization based on response surface methodology can maximize the extraction performance. At 30 ° C, the total polyphenol yield is 17.27 ± 0.93 mg. Testing at temperatures higher than 30 ° C to a maximum of 80 ° C is not conducive to increasing production. The extracts obtained from HP - β - CD had slightly higher polyphenol content than those prepared with conventional solvents (such as ethanol and methanol aqueous solution), and showed similar antioxidant properties. The main polyphenols identified in the extract were neochlorogenic acid, chlorogenic acid, caffeic acid and ferulic acid. The results of this study showed that Hydroxypropyl Betadex could be used as an efficient and green method to recover PP polyphenols at near ambient temperature. The aim of this study was to develop a simple and green extraction method for the efficient recovery of PP polyphenols using hydroxypropyl β - cyclodextrin (Hydroxypropyl Betadex).
