| 目的 探讨壳聚糖基抗菌保鲜膜(Chitosan-based Antibacterial Preservative Film，CAPF)对采后油豆角的保鲜效果。方法 分别以质量损失率、腐烂率、色差、呼吸强度、Vc含量、还原糖含量、超氧化物歧化酶(SOD)活性和丙二醛(MDA)含量为指标，考察CAPF对油豆角的贮藏效果。结果 CAPF对油豆角的保鲜效果良好，在贮藏18 d时，CAPF处理组的质量损失率为15.27%，是对照组的62.71%;腐烂率为6.3%，仅是对照组的31.3%。相较于其他组，CAPF组有效地降低了贮藏期间油豆角的黄化速率，抑制呼吸强度的上升，更好地延缓了油豆角中维生素C和还原糖的降低，使油豆角维持了较好的SOD活性，有效抑制了MDA的积累。结论 CAPF能有效提高油豆角的贮藏质量，可用于其保鲜。 |
| 英文摘要: |
| The work aims to discuss the preservation influence of chitosan-based antibacterial preservative film (CAPF) on the storage of postharvest snap bean. Weight loss rate, decay rate, color difference, respiration intensity, Vc content, reducing sugar content, superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were used as indexes to study CAPF on snap bean preservation. It turned out that CAPF had a good preservation effect. When stored for 18 days, the weight loss rate of CAPF treatment group was 15.27%, which was 62.71% of the control group; the decay rate of CAPF treatment group was 6.3%, which was only 31.3% of the control group. Compared with other treatment groups, CAPF treatment group can effectively reduce the etiolation rate, inhibit the rise of respiratory intensity, delay the decline of Vc and reducing sugar content, maintain SOD activity, and effectively inhibit the accumulation of MDA. CAPF can effectively improve the storage quality and can be used for snap bean preservation. |
