摘要：
Objective: To investigate the effect of dielectric barrier discharge cold plasma (DBD) treatment on the cell wall metabolism and softening characteristics of Xiaobai apricot during storage. Methods: Xinjiang-grown Xiaobai apricot fruits were treated with DBD for 40 s (voltage of 90 kV), and stored at 4 ℃ and 95% relative humidity for up to 42 days. The contents of cell wall components, cell wall metabolic enzyme activities, and quality indicators of apricot fruits were measured every seven days. Results: DBD treatment improved the quality of apricot, reduced the contents of malondialdehyde (MDA) and hydrogen peroxide, and significantly inhibited cell wall-degrading enzymes. It also delayed the dissolution of pectin and the degradation of cellulose, and inhibited the migration and loss of water in apricot fruits. Transmission electron microscopy (TEM) showed that DBD treatment helped to maintain the cell wall structure, thus making it more uniform and complete. Conclusion: DBD treatment can effectively inhibit the activities of cell wall-degrading enzymes of apricot fruits during storage, thereby enhancing the cell wall structure and delaying fruit softening. © 2024 Chinese Chamber of Commerce.
