| 中文摘要: |
| 为掌握番木瓜烫漂的最佳工艺，在单因素试验结果的基础上，采用响应面法优化能保持木瓜较高Vc
保留率和较低过氧化物酶（POD）相对活性的烫漂条件，得到漂烫温度、时间、切块大小的最佳工艺组合。结果表
明，番木瓜速冻前漂烫的最佳工艺为漂烫温度100℃、漂烫时间1.26…min、番木瓜切块2.7…cm，此时番木瓜的Vc
损失率为12.64%，POD相对活性为6.68%。经过漂烫处理的速冻番木瓜在贮藏期具有较好的Vc保留水平。 |

| In order to obtain the optimum bleaching process for papaya，on the base of single factor experimentsabout blanching temperature，blanching time and cutting size，the response surface regression with Design-expert 8.0was used to optimize the blanching conditions，to obtain the fruit with higher Vc retention rate and lower peroxidase（POD）activity. The results showed that the optimum blanching process before quick freezing of papaya was as follows：blanching temperature of 100℃ for 1.26 min，cutting size of 2.7 cm. Under the conditions，the papaya Vc loss rate was12.64%，relative activity of POD was 6.68%. After blanching treatment，the quick-frozen papaya had a good Vc retentionlevel in storage period. |
