How to save the best strawberries 1
The best way to keep strawberries fresh is to freeze them in a low-temperature freezer storage and low-temperature refrigeration.
This is the most effective method of preservation of all strawberry preservation techniques, low-temperature cold, including low-temperature storage and frozen preservation. Low-temperature storage can reduce the infestation of pathogens to reduce respiration, delay aging, thereby extending the storage period of strawberries. Quick-freeze storage cooling fast, intercellular generation of small ice crystals, so that the cells from damage, in order to better maintain the original appearance of strawberries and freshness.
Reason: strawberries are suitable for storage in a cool place below 10 degrees and above 0 degrees, and too high a temperature will make strawberries easy to rot and spoil. Strawberry harvested in -3 ℃ storage 4 days can occur frost, and the temperature & gt; 5C when the rot is serious, close to the freezing point -1.0 ℃, can be stored for about 1 month. Therefore, strawberries, like most other fruits, in the absence of frost damage, the lower the storage temperature, the better. Humidity is very important for strawberry storage, high humidity or water is extremely unfavorable to strawberry storage. Its tissue is young, very easy to produce mechanical injury, high humidity is very easy to rot, and produce odor.
Detailed operating methods:
1, select the fruit shape integrity, maturity of about 80% of the strawberry fruit, in addition to the stalk and the number of slices: and then put into the pool of rinsing well, the surface of the water dry first into the 25 ℃ of the quick-freezing freezer for quick-freezing, directly to the strawberry fruit to the center of the temperature reaches 15 ℃ after packaging.
2, packaged into a low-temperature cold storage. Strawberry quick-frozen freshness temperature of about 18 ℃ is appropriate, in this environment strawberries can be stored for 12 to 18 months. And the fast east after the low-temperature freezer storage of strawberries out of the library at 5 ℃ -10 ℃ under the false slow thawing 80-90 minutes, the quality of strawberries is the best, and can maintain a very good taste.
Note:
Before storing strawberries, wipe the strawberries clean, and don't touch the strawberries, or the strawberries will be broken faster. Store the strawberries in an airtight container, line the container with paper towels to absorb excess moisture from the strawberries, you can line them up to make sure they are not touching each other, and finally label the container with the date of storage.
Fresh strawberries, if not after the freezing cold storage frozen, at 1 ℃ low-temperature preservation of cold storage can also be stored for about 30 days, the quality of the stored strawberries is also very good. Strawberry low-temperature cold storage temperature should not be lower than 3 ℃, or storage 3 ~ 4 days or so there is the phenomenon of frost damage.
Strawberries how to save the best 21, first of all, strawberries try to save in the refrigerator. Don't put them in the sun or room temperature for too long, and avoid exposure to the sun.
2. Second, sprinkle some sugar on the washed strawberries to keep them fresh too.
3. Next, don't always pinch the surface of the strawberries, and when carrying and picking strawberries, hold them gently and be careful not to damage the strawberry tissues to minimize the chances of spoilage.
4. Then, put them in a ventilated place, and they can usually be kept for 1--2 days. Do not smother the strawberries in the bag, open the mouth of the bag, or tie some holes.
5, and, frozen strawberries are also a good choice of way. Many people consume frozen strawberries and the flavor is great.
6, finally, buy back the strawberries do not wash off all, eat as much as wash as much as you can eat, eat not finish put back in the refrigerator to save.
Nutritional value of strawberries:
Strawberries are rich in nutritional value, known as the "Queen of Fruits", rich in vitamin C, vitamin A, vitamin E, vitamin PP, vitamin B1, vitamin B2, carotene, ellagic acid, Aspartic acid, copper, strawberry amine, pectin, cellulose, folic acid, iron, calcium, ellagic acid and anthocyanins and other nutrients.
In particular, the content of . Vitamin C, its content than apples, grapes are 7-10 times higher. And the content of malic acid, citric acid, vitamin B1, vitamin B2, as well as carotene, calcium, phosphorus, iron content is also higher than apples, pears, grapes 3 to 4 times.
Strawberries how to save the best 3
1, buy strawberries, do not buy too much, eat strawberries must be clean, but not all clean, washed strawberries should be eaten at one time can not be left, the rest of the strawberries did not wash the strawberries can be placed in the refrigerator inside the refrigerator, but can only be saved for about 1-2 days.
2, pick strawberries when you must choose not damaged strawberries, strawberry skin is very thin, very easy to be squeezed collision damage, the bag should be gently held and put.
3, the preservation of strawberries should not be placed in high temperature places, strawberries are suitable for storage in a cool place below 10 degrees, the temperature is too high will make strawberries easy to rot and spoil.
4, strawberries contain high water, strawberries will dry up after losing water. We can find a sealed bag to put the strawberries into the inside, and then seal the bag mouth, and then placed in the refrigerator inside the cold so that you can save some longer.
5, if you want to save strawberries longer you can wash the strawberries, and then drain off the water in the plastic box and then put it in the refrigerator inside the freezer, so that the strawberries can be put a longer time.
