Abstract:

Abstract： To understand effects of different packaging on lipid peroxidation and antioxidant ability of Torreya grandis nuts during storage at room temperature, we used T. grandis nuts and measured acid value, peroxide value, total phenols, DPPH scavenging activity and inhibition of linoleic acid oxidation by TBA of nuts during storage. Results showed that content of total phenols decreased, and acid value and peroxide value increased in both raw and processed nuts of T. grandis, which demonstrated that lipid oxidation occurred. Packaging of LDPE film with vacuumed reduced the increase in acid value and peroxide value, kept high level of total phenol contents, alleviated the decrease in DPPH scavenging activity, inhibited linoleic acid oxidation by TBA, and relatively enhanced antioxidant ability.

Key words: Key words： Torreya grandis nuts, LDPE film with vacuumed, lipid oxidation, antioxidant
