Abstract: The products of physiological metabolism and relative enzymes activities of Dianjiang pummelo (Citrus maxima) with ice treatment were tested during storage. The results showed that ice treatment decreased the rate of respiration and the accumulation of alcohol and malondialdehyde, malondialdehyde (MDA) were significantly slowed down. Ice treatment also increased the activity of peroxidase (POD) in peel, and thus reduced the incidence of pulp granulation.

Key words: ice treatment, products of physiology metabolism, enzyme activity, granulation control
