How to preserve spinach without putting it in the refrigerator? Can spinach be frozen without blanching
Wrap it with paper towel and put it in the fresh-keeping box. When choosing spinach, you should choose fresh spinach, and avoid putting it in a wet plastic bag. Too much water will cause the spinach to rot. When storing spinach, you should first wrap it with a paper towel, and then put it in a fresh-keeping box or bag, and then put it in the refrigerator. Refrigeration can last up to ten days. Also, don't put spinach together with fruit that can produce ethylene, or it will cause spinach to rot faster.
Growth environment
Spinach is a typical long sunshine plant, and the temperature range of flower bud differentiation under long sunshine conditions is very wide. Its growth and development requires high temperature. The optimum temperature for seed germination is 15-20 ℃. If the temperature is too low or too high, the germination rate will be reduced. The spinach leaves grow fastest when the daily average temperature is 20-25 ℃. Spinach has strong cold resistance and will not freeze to death even at - 10 ℃.
Spinach grows most vigorously under the environmental conditions of 80% - 90% air humidity and 70% - 80% soil humidity, showing thick leaves, good quality and high yield. When spinach is short of water during the growth period, its growth slows down, its mesophyll ages, its fiber increases, and it is prone to diseases. Spinach is suitable for growing in rich organic matter, fertile loam or sandy loam. The suitable soil pH value is 5.5-7. When the soil pH value is below 5.5 or above 8, the growth is poor.
How to keep fresh spinach for a long time
The methods for long-term preservation of fresh spinach are as follows:
1. Refrigerate spinach
If you can't eat all the spinach you just bought from the market, you can put it in the refrigerator for storage. Of course, it is not necessary to buy the spinach directly and put it in the refrigerator, but it needs some treatment. You can first put the spinach at room temperature, leave it for a day, air dry the water on the leaves, and then wrap it with a kitchen towel.
Put the spinach root down in the refrigerator for refrigeration. It is generally OK to keep it for about a week in this way. The spinach will not rot.
2. Frozen storage of spinach
It is also possible to preserve spinach by freezing, but there are certain precautions when using freezing to preserve spinach. First, clean the spinach, cut it into sections, and then scald it slightly with salt water. Finally, wrap it in plastic bags for food and divide it into packages, and put it in the freezer for freezing.
In this way, it can be stored for a long time, and there is no problem to put it out for several months before eating.
Important points:
If the spinach is not rotten, it must be properly stored. The refrigeration method and freezing method described above can be used for reference. However, no matter which preservation method is used, the preliminary work should be done well. It is not directly used for refrigeration or freezing. If it is done in this way, spinach cannot be eaten.
Also, the spinach you bought must be fresh and high-quality. If the spinach you bought is not fresh, it is meaningless to preserve it. It is suggested here that fresh spinach is the most suitable food for everyone. If you can't finish eating it, you should use these methods to preserve it.
Storage and preservation methods of spinach
First, the spinach just bought should be left at room temperature for a day. This method is not only to make the leaves as dry as possible, but also to help distribute the medicine in the vegetables. Then directly wrap it with clean paper towel and put it into a sealed bag. It should be noted that spinach should be placed with the root facing down, and then refrigerated. In this way, spinach can be stored for about four to seven days.
Second, if you buy spinach whose roots have been removed, it is very easy to age, and the storage time is very short. So we should eat as soon as possible.
The third kind: wash the spinach you bought, cut it into sections, put it in salt water, scald it, and then divide it into bags for sealing. Store in the freezer after sealing. Frozen spinach is very convenient to use. You can cook soup and stir fry vegetables without unfreezing them in advance.
Fourth: wrap it with clean paper. Wrap the spinach in clean paper and put it into a plastic bag. The bag should not be too sealed. Then put it in the lower layer of the refrigerator for about five days. Soak withered spinach in water to restore its original appearance.
Fifth: Boil spinach and freeze it. We can put them into containers that can hold spinach according to the amount of food we eat each time, and then put them into the refrigerator to freeze.
The sixth method: buried in the soil. The best storage temperature for spinach is about 21 ℃. Dig a not too deep ditch in an unventilated place, bundle fresh spinach without rotten leaves and insect pests, and put the root down into the ditch. Sprinkle some soil on it, and it can be kept for more than a month in this way.
Seventh: How to preserve spinach after blanching? We must pay attention not to freeze it. Because the spinach will rot when it freezes and melts again. It can be directly put in the cold room like this, and the temperature is set at about 12 degrees Celsius.
Don't wash it with water, keep it dry, and then use plastic wrap. Don't lose moisture. It can be stored for about ten days in this way.
The eighth kind: spinach is very perishable, as long as it is above freezing point, it is close to zero degrees Celsius. The lower the temperature, the longer the storage time of spinach, which is close to zero ℃, can be stored for about three weeks. With the increase of storage temperature, the storage time shortens rapidly.
