摘  要：
以红富士苹果为试材,研究7.5 k J/m2剂量短波紫外线(ultraviolet-C,UV-C)处理对苹果常温和低温条件下贮藏性和品质的影响。供试苹果经7.5 k J/m2 UV-C照射后,分别贮藏在20℃和0℃条件下,定期测定果实质量损失率、呼吸强度、硬度、可溶性固形物含量(soluble solids content,SSC)、可滴定酸含量、超氧化物歧化酶(superoxide dismutase,SOD)活性及丙二醛(malondialdehyde,MDA)含量。结果表明,不论是常温还是低温条件下,整个贮藏过程中,UV-C处理组果实质量损失率、呼吸强度均较对照低;果实硬度、可滴定酸含量呈下降趋势,但处理组高于对照组;SSC整体呈先上升后下降趋势,但处理组较对照组下降缓慢;SOD活性总体呈先上升后下降趋势,但UV-C处理组活性始终高于对照组;果实MDA含量均呈上升趋势,但处理组上升缓慢。可见,采后苹果经适宜剂量UV-C照射能减轻质量损失,降低呼吸强度,减缓果实硬度、SSC及可滴定酸含量下降,保护膜完整性,延缓衰老,对保障品质,延长贮藏保鲜期有良好效果。

摘  要：
In the present work, we examined the effects of treatment with 7.5 k J/m2 UV-C on the storability and quality of Fuji apple fruits at room temperature and low temperature. Test apples were stored at 20 or 0 ℃ after being treated with 7.5 k J/m2 UV-C. Weight loss rate, respiration rate, soluble solids content(SSC), titratable acid content(TAC), superoxide dismutase(SOD) activity and malondialdehyde(MDA) content were measured regularly during storage. The results showed that weight loss rate and respiration rate of UV-C treated fruits were lower than those of controls; fruit firmness and titratable acid content decreased but their levels in the treatment group were higher than those of control; SSC increased first and then declined, but compared with the control fruits, SSC of the treated fruits decreased more slowly; SOD activity rose first and then decreased, but was always higher in the fruited treated with UV-C than in the control ones; and MDA content in both control and treated fruits showed an upward trend, but increased more slowly in the treated ones. Therefore, treatment with the appropriate dose of UV-C can exert good effects on maintaining the quality and extending the storage period of harvested apple.
