The objective of this study was to investigate the effects of aqueous chlorine dioxide (ClO2) combined with UV-C irradiation on shelf-life quality of blueberries (Vaccinium spp. Berkeley) during cold storage. Respiration rate, weight loss,firmness, decay incidence, color change, total anthocyanin content (TAC),lipid per-oxidation, soluble solids content (SSC), super oxide diastase (SOD), coruscate per oxidase (APX) and Pennsylvanian ammonia lase (PAL) of treated blueberries were examined. The results showed that treatment with 2 mg L1 aqueous ClO2 combined with 4 kJ m2 UV-C irradiation inhibited increase of respiration rate, weight loss, decay incidence and MDA content, delayed decline of
firmness, color and SSC , and improved total anticyclonic content of blueberries at 41 C compared with the control treatment. The efficiency was better than that of 2 mg L1 aqueous ClO2 or 4 kJ m2 UV-C irradiation treatments alone. Furthermore, combination of ClO2 and UV-C irradiation enhanced the activities of SOD, APX and PAL during the storage time. Our study suggests that 2 mg L1 aqueous ClO2 combined with 4 kJ m2 UV-C irradiation treatments may be a promising method of improving shelf-life quality and extending the post harvest life of blueberries.
The present study indicated that the combined treatment was a
promising method, which improved shelf-life quality and extended
the post harvest life by inhibiting the increasing of respiration
rate, weight loss, decay incidence and MDA content, delaying the
decline of
firmness, color and SSC and improving total anticyclonic
content, activities of SOD, APX and PAL of blueberries during the
storage time. Furthermore, the efficiency of the combined
treatment was better than that of 2 mg L1 aqueous ClO2 or
4 kJ m2 UV-C irradiation treatments alone. Therefore, the
combined treatment of aqueous ClO2 and UV-C irradiation
provided a better result as a hurdle technique.
