1. Raw material treatment: select extra-large plums, peel and remove seeds manually, and then desalt. Soak in plenty of clear water for desalination, and about 1-2% salt remains in the pulp, which can be slightly salty. Drain the water and send it to the curing barn for semi-drying or semi-drying.

2. Preparation and sugar infiltration of sugar solution: 50 kg of semi-dry embryo is prepared into 40% sugar solution with 40 kg of sugar, that is, 50 kg of sugar solution contains 20 kg of white sugar and 30 kg of water, and 40 kg of sugar needs 60 kg of water. Boil and dissolve white sugar to make 40% sugar solution; Adding 65438 000g to 65438 050g of edible citric acid into the sugar solution; 30g of clove, 30g of star anise, 30g of fennel, 30g of cinnamon and other spices are crushed, put into a cloth bag and added into the sugar solution; Salt100g to150g; Mix 25 grams of potassium sorbate together, heat and boil, pour it into a crock or stainless steel pot, and add 50 kilograms of plum embryo while it is hot for sugar stains. The next day, the concentration of the sugar solution was reduced to 20-22%, and the diluted sugar solution was extracted and concentrated to increase the sugar content by 25-27%, that is, to increase the sugar content by 5% on the original basis, and then poured into the raw materials while it was hot for sugar stains. After 65,438+0-2 days, this operation is repeated, and the sugar content is increased by about 5% each time until the sugar solution concentration is increased to 60-65.

3. Drying: the water content of the finished product reaches 28-30%.

4. Packaging: You can use three layers of wrapping paper, the first layer is film, the second layer is paper, and the third layer is trademark paper.

This kind of products are semi-dry, semi-wet, black in color, and have unique flavors such as aroma, sweetness, sour taste and salty taste.

Li is also known as Plum, Shan Mei and Jade Emperor Mei. The ancient name Jiaqingzi, according to Shu Wei's Two Classics in the Tang Dynasty, said: "There are plum trees in Jiaqingfang, Kyoto. In fact, it is sweet and fresh, which is the beauty of Kyoto, so it is called Li Jiaqing. Today, people say that Jia Qingzi is familiar with the title and can remember it without adding Li. " South of the Yangtze River in China, some people still call Li Jia or Jia (this is the result of the homonym of "green" and "English").
