| 摘 要： | 以‘巴西’香蕉(Musa nana‘Baxi’) 为材料, 研究了冷激处理对果实常温下后熟软化的影响。结果表明, - 20 ℃冷空气处理2.5 h明显延迟了后熟软化; 同时也延缓了多聚半乳糖醛酸酶(PG)和淀粉酶活性上升, 进而抑制了果胶和淀粉的降解, 对维持香蕉硬度起重要作用。

| Abstract: | The effect of cold shock treatment on softening of postharvcest‘Baxi’bananas was investigated. The results showed that the treatment of - 2-0 ℃ cold air for 2. 5 h significantly delayed fruit softening. Cold shock treatment inhibited the activities of polygalacturonase and amylase , and delayed the degradations of pectin and starch which resulted in a delay in fruit softening and a maintainance of fruit firmness. However , cold shock treatment did not affect the pectinesterase activity which decreased gradually during fruiting softening. |

| Keywords: | Banana Cold shock treatment Softening Polygalacturonase Amylase |
