Embodiment 1
[0015] Clean the fresh intestines, soak them for 20 hours, and then peel and scrape them. When peeling and scraping, the intestine can be divided into four layers: mucosa, submucosa, muscular layer and serosa from inside to outside. Then wash it clean, test it with water, cut off the damaged intestines with holes, and make a handful for every 5 (the total length is about 90 meters), then salt them with 0.5 kg of refined salt, and put them in a closed container. Finally, fill the container with a mixture of 20% carbon dioxide, 50% nitrogen and 20% oxygen. Sampling and testing the casings are light red, white or milky white, the visual effect is good; pulling, the toughness is sufficient; checking the bacteria content, all meet the standard.
Embodiment 2
[0017] After processing according to the sausage casing processing method described in Example 1, put the casing into an airtight container. Fill the container with a mixture of 23% carbon dioxide, 57% nitrogen and 21% oxygen. Sampling and testing the casings are light red, white or milky white, the visual effect is good; pulling, the toughness is sufficient; checking the bacteria content, all meet the standard.
Embodiment 3
[0019] After processing according to the sausage casing processing method described in Example 1, put the casing into an airtight container. Fill the container with a mixture of 25% carbon dioxide, 55% nitrogen and 25% oxygen. Sampling and testing the casings are light red, white or milky white, the visual effect is good; pulling, the toughness is sufficient; checking the bacteria content, all meet the standard.
