摘要：
In order to explore the effect of exogenous glucose (Glc) treatment on the postharvest storage quality and antioxidant metabolism of apricot fruit, ‘Saimaiti' apricot fruit from Xinjiang were stored for up to 49 days at (0 ± 1) ℃ and a relative humidity of 90%-95% after vacuum osmosis treatment (holding for 2 min at 0.05 MPa followed by soaking for 5 min at atmospheric pressure) with different concentrations (100, 200 and 400 mmol/L) of Glc or distilled water as a control. Fruit quality and antioxidant metabolism-related indexes were determined during the storage period. The results showed that exogenous Glc treatment could effectively maintain the firmness, soluble solids content (SSC) and titratable acid (TA) levels, and significantly reduce the respiration intensity of apricot fruit, with the most pronounced effect being observed at 200 mmol/L Glc. In addition, exogenous Glc treatment increased the activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) in apricot fruit compared with the control group, and effectively maintained the contents of ascorbic acid (ASA) and glutathione (GSH), thus delaying the accumulation of superoxide anion radical, hydrogen peroxide, malondialdehyde (MDA) and the increase of cell membrane permeability. These findings indicate that exogenous Glc treatment could maintain the storage quality of apricot fruit by regulating its antioxidant metabolism during storage, which will provide a theoretical basis and technical reference for the application of Glc in postharvest storage and preservation of fruits and vegetables. © 2023 Chinese Chamber of Commerce.
