Influence of freezing process and frozen storage on the quality of fruits and fruit products

The effects of freezing and frozen storage on bioactive compounds in fruit products have not been completely elucidated, and the outcomes are often contradictory. Given the wide range of results, the aim of this review is to explore the effects of freezing, thawing, and storage conditions on the physicochemical quality of fruit products, including the phytochemical content. We also discuss how growing and environmental conditions can affect the freezing process and product quality. Studies show that cultivar selection, preharvest factors, and ripening stage are important factors that contribute to the freezing performance and the quality of fruit products.
