The main processing methods of Chinese cabbage are brewed and dried. 1. The brewed cabbage has the characteristics of compact organization, crisp texture, hypertrophy, and non-softening, and is suitable for making kimchi. The processing technology is similar to that of Chinese cabbage. The cabbage with fresh texture is selected and washed thoroughly. After draining, the cabbage is put into a special kimchi jar. The soaking solution contains 3% to 5% salt, and can be brewed for 3 to 5 days. Listing. During the brewing period, it should be noted that the jars must be air-dried first, and there must be no raw water, sinks, and bowl lids to maintain full water. If there is albuginea in the liquid level, they should be removed immediately. Such as adding a small amount of white wine, ginger and garlic can inhibit the growth of bacteria. 2. Drying generally uses hot air drying. (1) Process selection→cleaning→cleaning→separation→blanching→drying→packing→finished products (2) Operation technique 1 Selecting and removing impurities Select the species with higher dry matter content and fresh vegetables, remove the outer leaves , roots and stems. 2 Wash clean with clean water. 3 Cut the vegetables into 4 to 5 mm strips. 4 blanching in 0.2% sodium sulfite solution blanch 2 to 3 minutes, because the solution contains a certain amount of sulfur dioxide can prevent oxidation discoloration and can destroy the enzyme's hydrolytic activity, increase cell membrane permeability, promote water evaporation, and favorable drying. 5 After drying and blanching, drain the water and place it on a hot baking pan. Usually, lay 3 to 3.5 kg (3 to 3.5 kg/m2) per square meter, and let it enter the hot air dryer (or drying room). Should not be too high, warming in the middle, later cooling down to 55 ~ 60 °C. It takes 6 to 9 hours to complete the drying. 6 Packaged and stored products shall be packaged in time after being softened and graded. Dry products shall be stored in a clean and dark environment with a temperature of about 10°C and a relative humidity of 30%.
