Abstract: Effects of different storage temperatures on the quality of mulberry were studied at -18, -24 and -40℃. The results indicated that at -18℃ drip loss, vitamin C loss, anthocyanin and flavonoid loss, the degree of browning were higher than those at -24℃ and -40℃. Soluble polyphenol oxidase (PPO) activity increased at the early stage and significantly went down late while soluble peroxidase (POD) activity dramatically decreased after one-month storage and almost inactivated after three-month storage.

Key words: mulberry, frozen storage, quality change
