| 中文摘要: |
| 为比较不同蔬菜在冻结过程中的冻结特性，用SATO SK-L210T 温度计测定了6 种蔬菜的冻结曲线，分别对冻结点、冻结速率和最大冰晶生成带通过时间3 个冻结特征值进行对比分析。结果表明，6 种蔬菜的冻结曲线存在明显的冻结3 阶段，含水量和含脂量不同影响了各蔬菜的冻结特性，在-20℃，蔬菜达不到速冻要求。 |
| 英文摘要: |
| In order to compare the freezing characteristics of different vegetables during frozen process. Using the SATO SK-L210T to determine the freezing curves of six kinds of vegetables, freezing point, freezing rate and the zone of maximum crystallization time were compared. The results showed that the freezing curve of six vegetables had obvious freezing three-stage. The difference of water and fat content influenced the freezing characteristics of every vegetable. At the same time, the temperature at -20℃ could not satisfy quick-freezing. |
