Abstract: This study was implemented to investigate the effect of near freezing temperature (NFT) storage on the postharvest quality and antioxidant activity of ‘Golden Delicious’ apple fruit. NFT was set to be (-1.7 ± 0.2) ℃. Compared with storage at 0 ℃, NFT storage suppressed ethylene production and respiration rate, delayed the appearance of respiration peak, and maintained fruit color, higher soluble solids and titratable acid contents. In addition, NFT storage maintained higher levels of total phenols, and total flavonoids as well as higher antioxidant capacity. NFT storage retarded the increase of membrane permeability and malondialdehyde (MDA) content. Based on the results above, NFT storage should be recommended for improving the storage quality and antioxidant capacity of ‘Golden Delicious’ apple. This research provided a reference for the application of NFT storage in apple fruit storage.

Key words: near freezing temperature storage, ‘Golden Delicious’ apple, storage quality
