In addition, the cherry skin is thin, and the pores of the fruit skin are also large. During the storage process, it is easy to lose water, resulting in the loss of skin luster and wrinkling of the skin, which seriously affects the product quality of cherries. Usually, the products sold during the Spring Festival are made from a large number of freshly stored cherries. After the rotten and wrinkled fruits are selected, the better quality ones are selected for sale, which is also one of the main reasons for the price increase.

Embodiment 1
[0014] Example 1 A kind of fresh-keeping method of cherry is characterized in that, comprises the steps:
[0015] Step 1. Harvesting: When the cherries are fully ripe, choose a sunny day at 8-11 am or 3-6 pm for harvesting. During the harvesting process, be careful to handle and avoid collisions and extrusions between cherries. and damage the cherry fruit;
[0016] Step 2, cooling treatment: sorting and grading the harvested cherry fruits, removing rotten fruits and abnormal-shaped fruits, and completing the arrangement of the fruits, and then put the arranged cherries into the fresh-keeping box, and put the fresh-keeping box open into the refrigerator In the warehouse, adjust the temperature of the refrigerator so that the cherries cool down at a cooling rate of 3°C / h until the temperature on the surface of the cherry fruit drops to about 14-15°C, then stop the cooling so that the temperature on the surface of the cherry fruit remains at 14-15°C about;

Abstract
The invention relates to a preservation method of cherry. A good preservation effect is achieved by combining a unique preservation mode with a preservative aiming at the physiological characteristics of the cherry and the problems in the preservative storage process. The preservation method is efficient to keep a fruity flavor and a fruity taste; meanwhile, the preservative ingredient used in the preservation method can form a protective film on the surface of the cherry; the damage to epidermal fruit wax in a cleaning process is compensated; loss of moisture in the preservation process is reduced; meanwhile, good glossiness also can be kept on the cuticle surface; in addition, air holes in the cherry surface are closed by cooling treatment in the preservation process; loss of the fruity flavor is reduced; meanwhile, diffusion of the moisture in the fruit and at the peripheries of the air holes is avoided. Therefore, the preservation method has important significance in keeping fruit texture and fruity taste of the cherry.
Description
technical field [0001] The invention belongs to the field of fresh-keeping of fruits and vegetables, and relates to a fresh-keeping method of cherries. Background technique [0002] Cherries, also known as wedge jingtao, cherries, etc., are bright in color, crystal and beautiful, red like agate, yellow like fat, and rich in nutrition. The fruit is rich in sugar, protein, vitamins, calcium, iron, phosphorus, potassium, etc. This element belongs to the high-end variety in the fruit market. Even in the peak season of its harvest, the price is more than 15 yuan / kg. Because it is not resistant to storage and has a short fresh-eating period, it is mostly concentrated in May-August. In mid-September, the cherries on the market were basically off the shelf, and the prices of a few preserved or imported cherries were also sold at high prices, ranging from 50 to 60 yuan per catty, to hundreds of yuan per catty, and the price of cherries reached 100 yuan per catty during the Spring Fes...
