How is northeast black frozen pear made?

The production method of northeast black frozen pear is as follows:

1. If you choose late-maturing pear varieties, such as Nanguo pear, Jianba pear and Gai Hua pear, you will be more likely to succeed. After selecting pears, put them in cartons or plastic baskets, number them on cartons or plastic sheets, and store them in a cool, dry and well-ventilated room or freeze them.

When the temperature drops in winter, pears will naturally freeze. In this process, the cell structure of pear was destroyed during freezing, and the polyphenol oxidase in the cells combined with oxygen to produce enzymatic browning, which led to the blackening of the peel.

3. After thawing the pears that have been cooled in winter or frozen at room temperature for five hours, continue to put them in the freezer for freezing.

4. Pour the black pear into cold water. It is best to soak most pears in cold water. This step can thaw the pears. After thawing, the northeast black frozen pear is ready.
