摘　　要：为了更好地了解鲜茧经不同冷冻条件保存后茧质性能变化,以同一庄口的蚕茧为研究对象,设置不同的冷冻条件进行保存。对干茧、鲜茧、不同温度冷冻不同时间后鲜茧的茧质以及茧层渗透性能进行测试和分析。结果表明:在其他工艺条件相同的条件下,鲜茧经冷冻保存后蛹体含水率略有减少,茧层含水率增大;好蛹率测试结果显示,如需较长时间保持蛹体新鲜,储藏温度至少要低于-20℃;鲜茧经冷冻保存后茧层初期丝胶溶失率变大,茧层渗透性能增强,内层落绪次数减少,有利于缫丝过程中茧丝的顺利离解。In order to better understand the changes of cocoon properties after cryopreservation of fresh cocoon under different freezing conditions,the cocoons from the same place were chosen as the study subjects and were preserved under different freezing conditions.Cocoon quality and cocoon layer permeability of dried cocoon,fresh cocoon and fresh cocoon with different freezing time at different temperatures were tested and analyzed.The results show that in the same process conditions,the moisture content of pupa decreases slightly after cryopreservation,and the moisture content of cocoon layer increases.The test results of good pupa rate show that if the pupa remains fresh for a long time,the storage temperature should be below-20 ℃.After cryopreservation of fresh cocoon,the early sericin dissolution-loss ratio of cocoon layer becomes larger,the permeability of cocoon layer increases,the times of inner dropping end decreases,which is conducive to the smooth dissociation of bave in silk reeling process.
