How to freeze vegetables at home

The temperature used for commercial quick freezing will reach below minus 30 degrees Celsius, but the temperature of ordinary refrigerators at home is often not so low, and the food will take longer to freeze. However, freezing can also slow nutrient loss from vegetables. In addition to buying quick-frozen vegetables, it is also a good choice to try to freeze vegetables at home, not only do you no longer have to worry about the vegetables that you buy will rot quickly, but also facilitate subsequent cooking.
