It is being used as an animal feed or discarded to the environment, which could cause an environmental problem. A new integrated process of maceration and freeze concentration was studied to recover the antioxidants from the pomegranate peel. The low temperature used in the freeze concentration assists in concentrating a high quality of antioxidants. The concentrated peel solution was tested for an antioxidant activity via 2, 2 diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method. It was found that methanol gave the best extraction of antioxidants from pomegranate peel. The highest antioxidant recovery with DPPH radical scavenging of 96.14 was obtained at -16 °C of coolant temperature and 30 min of freezing time (p < 0.05). The integrated process has proven to be an effective method to recover the antioxidants from pomegranate peel and can be applied to recover other bioactive compounds. © 2020 Walter de Gruyter GmbH, Berlin/Boston. date: 2020 publisher: De Gruyter Open Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85080965832&doi=10.1515%2fijfe-2019-0232&partnerID=40&md5=210cecbdcf12f467db63cfca4419ed5c id_number: 10.1515/ijfe-2019-0232 full_text_status: none publication: International Journal of Food Engineering volume: 16 number: 10 refereed: TRUE issn: 21945764 citation: Samsuri, S. and Li, T.H. and Ruslan, M.S.H. and Amran, N.A.
