Can raw chestnuts be frozen?
1. Storage characteristics of raw chestnut
Raw chestnut has a short storage period, is easy to rot and mold at room temperature, and cannot be stored for a long time. In addition, raw chestnuts will lose water and taste bad during storage, so appropriate storage measures are needed.
2. Frozen storage of raw chestnut
Raw chestnuts can be frozen. Freezing can effectively prolong the storage period of raw chestnut, while maintaining its nutritional components and taste.
During the frozen storage of raw chestnuts, the following points should be noted:
1, choose fresh raw chestnut.
Selecting fresh and intact raw chestnuts for frozen storage can ensure that the frozen raw chestnuts have good quality and taste.
2. Boil first.
In order to peel off the skin of raw chestnut more easily and remove pectin, vitamins, enzymes and other ingredients that have been solidified by juice, we need to cook raw chestnut first.
Step 3 peel off the peel
Before freezing raw chestnuts, it is necessary to peel off the skin and cut the raw chestnuts into appropriate sizes. This helps to maintain the uniformity and convenience of eating when frozen.
4. Choose the appropriate refrigeration method
The cold storage temperature of raw chestnut is generally around-18℃, so you can choose refrigerators, cold storage and other equipment for storage. At the same time, you need to pay attention to moisture-proof, antifreeze and thorough sealing to maintain air circulation.
Third, the influence of frozen storage.
Although frozen storage can prolong the storage period of raw chestnut, it may also bring the following effects:
1, extremely low temperature causes frostbite to the pulp and affects the taste;
2. Frozen raw chestnut is easy to produce ice crystals, and it is easy to cause water loss when thawing;
3. After freezing treatment, the content of vitamin C in raw chestnut decreased, so it was not suitable for long-term storage.
Four. Matters needing attention in frozen storage
The following items should be paid attention to when raw chestnut is frozen:
1. Before freezing, fresh raw chestnuts should be washed and dried;
2. In the freezing process, it is not advisable to put too many raw chestnuts into the refrigerator or cold storage to prevent the cold air from fully circulating;
3, the freezing time should not be too long, it is best to eat within one month.
Conclusion:
Raw chestnut can be preserved by freezing, but special attention should be paid to peeling off the peel and choosing the appropriate refrigeration method, and the freezing time should not be too long. Although frozen storage will have some effects on the taste and nutritional components of raw chestnut, compared with the benefits of long-term storage, these effects are acceptable.
