Its acidity stimulates the salivary and gastric glands to secrete digestive juices, promotes digestion, nourishes the stomach and intestines, improves gastrointestinal function, and promotes intestinal absorption.

Green plum has sweet and flat taste, large fruit, thin skin, glossy, thick flesh, small core, crisp and fine, juicy, high acidity and sweet aroma. It contains many amino acids needed by human body, rich in fruit acids and vitamin C. During the processing, the skin is not easy to crack and the contents are not easily lost. During the curing process, only the right amount of salt is added and no other additives are added to achieve a shelf life of more than 12 months.
The preparation method of plum is as follows.
1、Select material: choose plum varieties with large fruit shape, small core, green and crisp color, and neat fruit shape. Generally speaking, it is appropriate to choose fruits with fat and tender shape, full flesh, fluffy and shiny surface, and the seeds are formed but not yet mature.
2、Curing: Take 7.5kg of table salt, 250g of alum, add water (the amount should be able to soak the fruit) to prepare a solution, and then soak the plum, curing for 48 hours until the plum color turns yellow.
3、Pinhole: make sour plum dice. When using a needle hole, the depth of the hole should reach the core of the fruit, which is called piercing. After piercing, continue to add salt for 3~5 days.
4、Rinsing: Pour the pickled plum blanks into alum solution (concentration: 0.1%) and soak them for 20 hours. During this period, change the solution once and rotate the solution frequently to remove most of the salt, while the fruit blank part is slightly salty.
5、Dyeing: Add 15kg of sugar, add appropriate amount of pigment, add water to dissolve and stir well, and pour into the dipping tank together with the plum blanks.
6、Sugar pickling: The initial sugar pickling usually takes 9 days. For the first two days, keep quiet. For the next seven days, add 1.5kg of sugar per day and open it in time to dissolve the sugar and make it penetrate evenly.
7、Fermentation: From the seventh day, the plum blanks are fermented with light alcohol. This fermentation can remove the bitterness of fresh plums, increase the penetration of sugar and improve the flavor of the product. However, fermentation should be controlled within 24 hours to prevent the plums from turning green and soft and rotting due to excessive fermentation.
8、Sugar curing: sugar curing period takes 10~20 days, during which 1.5kg of sugar is added every other day, paying attention to timely turning and replenishing the sugar solution. When the sugar curing to the 40th day, add all the remaining sugar, so that the sugar content of 50%. After a few days, the sugar content can be increased to 60% and finally to 65%. The whole process takes about 2 months.
9、Packaging: Put the product into a glass bottle with strict sterilization, pour in the original sugar brine, screw the cap tightly and put it in a cool place, which can guarantee the good quality for more than 1 year.
