The influence of different washings, temperatures, and packagings on anthocyanins of minimally processed pomegranate seeds was evaluated. No differences were found in anthocyanin composition after washing with different solutions, although a slight decrease in pigments occurred. Storage in perforated polypropylene bags preserved pigments and a slight increase in most anthocyanins occurred. During storage in modified atmospheres, anthocyanins increased at 1°C, but decreased at 8 and 4°C. The delphinidin derivatives were the most sensitive while cyanidin and pelargonidin derivatives were stable and increased slightly. The 3,5‐diglucosides were more stable than 3‐glucosides. Compared with storage at 1°C for 7 days in perforated OPP bags, unperforated OPP bags maintained the pigments better. However, stored an additional 4 days at 4°C to simulate domestic storage, they were better preserved in perforated films.
