Cherry ripens early and has the reputation of 'the first fruit in early spring'. Cherry belongs to juicy fruit, delicious but not easy to preserve. Many people who love to eat cherries may not know how to preserve cherries. So, how to preserve cherries fresh? Let's learn some preservation methods of cherries.
Keep the cherries in the refrigerator
At most, a few catties of cherries can be purchased at home, not too much. It can be stored in the refrigerator, and the temperature is about 2 ℃. This method can extend the shelf life of cherries to about seven days.
Methods: cherry was selected to distinguish the pedicled cherry from the non pedicled one, and the fresh cherry from the non fresh one. Wipe the cherry with paper to keep its surface dry and put it in the basket. Wash the cherry and drain it in the basket. Take a clean paper box, put a layer of napkin on the bottom layer, and then put cherry, put a layer of cherry and then put a layer of napkin, and so on until the cherry is loaded, and finally put a layer of napkin on the cherry. Put the cherry covered with paper towel into the refrigerator and keep it at about 2 ℃.
Note: the storage of cherry needs to be dry and low temperature. Therefore, how much to eat and how much to wash, do not refrigerate after soaking in water, and do not use plastic bags, which will produce water vapor and affect the storage. What's more, I want to remind you that you can't use plastic boxes, let alone remove fruit stems, otherwise cherries will soon deteriorate.
If the cherry is stored in a dark, dark and ventilated place without a refrigerator, the cherry can be packed in a mesh plastic bag and hung in a ventilated, dark and dry place, which can appropriately slow down the deterioration of cherry. However, this method can only be preserved for 2 ~ 4 days, or it will rot or lose moisture, too much drying.
The cherry is soaked in lemon juice for preservation. After the purchased cherry is washed with clean water, the water is dried, and then some pure lemon juice is taken. The processed cherry is put in the lemon juice, and then they are put into the refrigerator for refrigeration. This preservation method can extend the storage time of cherry to 10 to 15 days. Because lemon juice is a kind of acid material, it has excellent antisepsis, which can prevent the damage of microorganisms to cherry, but this method of cherry preservation costs a lot, and some people don't like it.
Preserved cherry can not only be eaten fresh, but also be processed into other foods with long shelf life. Fresh cherries in normal temperature weather, only about two days of preservation period, that is, cold storage using other methods, can only be stored for about 10 days, want to taste the fresh and delicious cherry all year round, it is best to process it before preservation.
Common cherry processing foods include: cherry sauce, cherry cans, cherry wine, etc. these processed cherries can be stored for a long time. In addition, cherry can also be pickled with sugar to make sugar cherry. No matter which way, the shelf life of cherry can be extended to more than one year, and people can eat this delicious fruit all year round.
The cherry is soaked in the fresh-keeping solution, washed clean with water, drained and put into the pre prepared fresh-keeping solution. The amount of cherry added is about 60% of the weight of the fresh-keeping solution. It can be sweetened after one to four months storage under natural conditions. Remove and drain the cherry from the preservative. Heat and concentrate the preservative solution until the sugar concentration reaches 28%. Soak the cherry in it for one day and take it out. Repeat 2-3 times to make the sugar concentration of the preservative solution reach about 38%.
The cherry processed by this method has good aroma and taste. In addition, after removing the stem and core of the cherry, it can be soaked in the concentrated fresh-keeping solution. After repeated 2-3 times, the sugar concentration of the preservative solution reached about 45%. Cherry processed in this way is very popular as an ingredient of ice cream or yogurt.
How to prepare preservative solution:
Preservative solution is a kind of acid sugar solution with appropriate preservatives. Sucrose, glucose or fructose can be used as sugar, and its concentration is appropriate when the osmotic pressure of the solution is balanced with that of the cherry. In this way, cherry can avoid swelling, cracking or shrinkage deformation, and maintain its original texture. The average sugar content of cherry is 12-16%, and the sugar concentration of preservation solution is 15-20%.
What should be paid attention to in fresh cherry preservation
1. Fresh cherries can generally be stored for about 2 days at room temperature, but they can be stored for 5 days if they are put in the refrigerator. In winter, the time can be longer. However, cherries should be eaten as soon as possible while they are fresh. If you can't eat them all at once, you'd better wash them as much as you can. If you want to store cherries, don't wash them first, so as not to damage the protective barrier of cherries.
2. Do not use plastic bags or plastic boxes to hold cherries, because poor air permeability, easy to cause cherry decay. In addition, the fruit stem can not be removed, and it is easy to be damaged if the fruit stem is removed.
