摘要:

以“大乌嘴”黄花菜为试材,采用壳聚糖处理结合纳米包装对黄花菜进行保鲜,研究其对黄花菜贮藏期间品质和生理变化的影响。结果表明:壳聚糖处理、纳米包装及二者结合处理都能延缓黄花菜的衰老。壳聚糖处理结合纳米包装对黄花菜的保鲜效果最佳,能够降低质量损失率,有效地抑制VC、还原糖含量的降低,保持较高的超氧化物歧化酶及过氧化氢酶活性。二者结合处理过的黄花菜在(4±0.5)℃、相对湿度75%~80%的环境中贮藏18 d后,好花率仍然保持在90%以上。

Abstract:

The daylily cultivar ‘Dawuzui’ was used to explore the effects of chitosan treatment combined with nanopackaging
on the quality and physiological changes of daylily during storage. Results indicated that chitosan treatment,
nano-packaging and their combination delayed the senescence of daylily. The quality of daylily was best preserved when
chitosan treatment was combined with nano-packaging. This combinatorial treatment decreased the rate of weight losses,
effectively inhibited the reduction of VC and sugar contents, and maintained higher activities of superoxide dismutase and
catalase. As a result, the marketable flower rate of daylily remained more than 90% after storage for 18 days at (4 ± 0.5) ℃
and a relative humidity of 75%–80%.

Key words: daylily, chitosan, nano-packaging, storage quality, physiology
