| 目的 探究自然冷源和机械制冷双向自动切换库对红薯在贮藏期间中生理指标的影响，研讨贮藏的可行性。方法 以普通地窖库为对照组进行实验，测试库内温湿度变化以及红薯的含水量、硬度、淀粉含量、MDA含量和可溶性固形物含量等生理指标(含水量和含量均以质量分数计)的变化情况。结果 在贮藏100 d时，双向库内红薯的含水量为72.18%，硬度为677.263 N/cm2，可溶性固形物含量为15.32%，MDA含量为4.25 μmol/g ，淀粉含量为16.05%，均优于普通地窖库内红薯的指标。结论 自然冷源和机械制冷双向自动切换库与普通窖藏库相比，能较好地维持红薯在贮藏期间所需的温湿度，保持了红薯硬度、含水量、淀粉含量和可溶性固形物含量等，减少了红薯在贮藏期间的损耗，对红薯的贮藏起着显著作用。 |
| 英文摘要: |
| The work aims to study the effects of natural cold source and mechanical refrigeration on physiological indexes of sweet potato storage and the feasibility of storage. Taking the ordinary cellar as the control group, the experiment tested the changes of temperature and humidity as well as the physiological indexes such as water content, hardness, starch content, MDA content and soluble solids content of sweet potato (content in mass fraction). When stored for 100 days, sweet potatoes in the bidirectional storage were superior to those in the common cellar, with water content of 72.18%, hardness of 677.263 N/cm2, soluble solid content of 15.32%, MDA content of 4.25 μmol/g and starch content of 16.05%.Compared with common cellar storage, natural cold source and mechanical refrigeration can maintain the required temperature and humidity of sweet potato storage, maintain the hardness, and content of water, starch and soluble solids of sweet potato, reduce the loss of sweet potato storage, and play a significant role in the storage of sweet potato. |
