First, the process Frozen donkey → Thawing → Raw material preparation → Pre-cooking → Block cutting → Canning with juice ↠Juice preparation ↓ Second, the production method 1. Thawing: Thaw the frozen donkey meat using cold water at around 20°C for approximately 12 hours. The surface should be free of ice, and the meat should be soft, with a bright red color. 2. Pretreatment: Remove all hard bones and cartilage from the thawed donkey meat. Trim away any surface impurities or unwanted parts, and cut the meat into pieces weighing about 1 kg each. 3. Pre-cooking: Boil the meat in a saline solution (0.6–1%) with a water-to-meat ratio of 1.5:1. Cook for 30 minutes until the meat is 7 to 9 out of 10 done, leaving a slightly bloody center. 4. Stripping and cutting: After pre-cooking, the meat is placed into a stripping machine to make it easier to handle. Once removed, it is cut into small cubes, approximately 2 to 3 cm in size, using a kitchen knife. 5. Preparation of juice: (1) Soup base: For 100 kg of water, add 4.5 kg of salt, 4 kg of sugar, 6 kg of soy sauce, 2 kg of starch, 0.25 kg of MSG, and 0.25 kg of white wine. (2) Spices: Mix 100 grams of white peony, 1500 grams of green onions, 700 grams of ginger, 150 grams of pepper, 150 grams of star anise, 150 grams of fennel, and 200 grams of chili powder. Use some of the soup water to prepare 10 kg of spice water. Heat the mixture for 5 minutes to dissolve the ingredients, then combine with the spice water. Add the white wine and MSG while the pot is still cooking. 6. Canning and filling: Each can has a gross weight of 781 grams, with a net content of 312 grams. It contains 190 grams of donkey meat and 122 grams of soup. Ensure that the meat is evenly distributed when loading the cans. 7. Exhaust sealing: Seal the cans under vacuum pressure greater than 400 mmHg to ensure proper closure and prevent contamination. 8. Sterilization and cooling: Perform sterilization using a gas extraction method. The process involves 15 minutes of heating, followed by 90 minutes of sterilization at 112°C, with back pressure maintained at 1–1.2 kg/cm². Afterward, cool the cans under back pressure to preserve quality and extend shelf life. Aluminum Fluoride CAS No.7784-18-1 Aluminum Fluoride Basic Information
