The effects of preservative (potassium sorbate or sodium pyrosulfite) on storage quality such as total colony number, colour L* value, polyphenol content, DPPH radical scavenging activity and pH of Choerospondias axillaris peel pulp at 4, 25 and 35 ℃ were first studied. The results showed that 0.050% potassium sorbate and 0.015%~0.050% sodium pyrosulfite could effectively inhibit the growth of microorganism. 0.015% sodium pyrosulfite had a good color protection effect during the pulping process and early storage stage of the pulp, but there was no significant difference between 0.015% sodium pyrosulfite and 0.050% potassium sorbate was found, when the storage time was prolonged (P>0.05). There was no significant difference in the polyphenols content and the free radicals scavenging rate of DPPH for the two groups during the pulping and storage process of pulp (P>0.05). Low temperature (4 ℃) was beneficial to the storage of pulp and the changes of L^* value and polyphenol content were in accordance with the first-order and zero-order degradation kinetics models, respectively.
