| 摘 要： | 银条是洛阳地区的特色蔬菜，其肉质嫩脆，营养价值高，但保存期短，易腐败变质。本实验目的就是通过真空冷冻干燥技术来延长其保存时间。工艺参数为：加热板温度为40℃，升华干燥时真空度20Pa、3．5h后开始解吸干燥，解吸干燥开始时真空度150Pa、解吸后期为20Pa，总共冻干6h。 |
| 关 键 词： | 银条 真空冷冻 干燥 调压法 |

| Abstract: | Stachys Floridana Schuttl.ex Benth is a kind of vegetable only growing in Luoyang, which is so delicate and has abundance nutrition. But it is very difficult to storage. The vacuum freeze-drying technology was introduced to delay the storage of Stachys Floridana Schuttl.ex Benth. The best technology of Stachys Floridana Schuttl.ex Benth is the temperature of heating board being 20℃, the pressure of sublimation being 20Pa, after 3.5h beginning desorption drying, it＇s prophase pressure being 150pa, the anapbase being 20Pa through doing orthogonal experiments. |
