Problems solved by technology

However, after the liver is isolated from the body, the blood will coagulate rapidly. With the coagulation of the blood, a large number of macrophages and other immune cells contained in the blood will accumulate in tens of thousands of hepatic sinusoids in the liver. , flushing and soaking can only wash away a small part of the toxins and harmful substances contained in the liver, and most of the toxins and harmful substances still remain in the sinusoids and capillaries of the liver
Therefore, the traditional animal liver detoxification method cannot completely remove toxins

Embodiment 1

[0045] A method for cleaning, detoxifying and preserving cell tissue of fresh animal livers, comprising the following steps:

[0046] S1: Quickly take out the complete fresh liver from the animal, remove the gallbladder, and keep the first hepatic portal blood vessels of the liver when taking out the liver; the length of the first hepatic portal blood vessels is kept about 3 cm; the taken out liver ensures the integrity of its surface capsule ;

[0047] S2: Gently spread the removed liver on a clean plane, quickly dissect the first hepatic hilum of the liver, find the upper and lower ends of the portal vein, biliary tract, hepatic artery and inferior vena cava, and insert the sterilized medical catheter into the portal vein and biliary tract And in the hepatic artery; fix the portal vein, biliary tract, and the connection between the hepatic artery and the catheter;

[0048] S3: Infuse the perfusate at 30°C into the ducts of the portal vein, hepatic artery and biliary tract, ...

Embodiment 2

[0052] A method for cleaning, detoxifying and preserving cell tissue of fresh animal livers, comprising the following steps:

[0053] S1: The complete fresh liver is quickly removed from the animal, the gallbladder is removed, and the first hepatic portal blood vessel of the liver is preserved when the liver is taken out; the length of the first hepatic portal blood vessel is kept at 3 cm; the removed liver ensures the integrity of its epidermis;

[0054] S2: Gently spread the removed liver on a clean plane, quickly dissect the first hepatic hilum of the liver, find the upper and lower ends of the portal vein, biliary tract, hepatic artery and inferior vena cava, and insert the sterilized medical catheter into the portal vein and biliary tract And in the hepatic artery; fix the portal vein, biliary tract, and the connection between the hepatic artery and the catheter;

[0055] S3: Infuse the perfusate at 35°C into the ducts of the portal vein, hepatic artery, and biliary tract...

Embodiment 3

[0059] A method for cleaning, detoxifying and preserving cell tissue of fresh animal livers, comprising the following steps:

[0060] S1: Quickly take out the complete fresh liver from the animal, remove the gallbladder, and keep the first hepatic portal blood vessels of the liver when taking out the liver; the length of the first hepatic portal blood vessels is kept at 4 cm; the taken out liver ensures the integrity of its surface capsule;

[0061] S2: Gently spread the removed liver on a clean plane, quickly dissect the first hepatic hilum of the liver, find the upper and lower ends of the portal vein, biliary tract, hepatic artery and inferior vena cava, and insert the sterilized medical catheter into the portal vein and biliary tract And in the hepatic artery; fix the portal vein, biliary tract, and the connection between the hepatic artery and the catheter;

[0062] S3: S3: perfuse the perfusate at 33°C into the ducts of the portal vein, hepatic artery and biliary tract, ...

Abstract

The invention relates to a method for cleaning a fresh animal liver, removing toxic matters in the fresh animal liver and keeping cell tissue in the fresh animal liver fresh. The method comprises the following steps: rapidly taking an intact fresh liver from the body of an animal, cutting off the gallbladder in the fresh liver and preserving a first hepatic portal inner blood vessel; carrying out rapid dissection, finding out a portal vein, a biliary tract, a hepatic artery and the upper and lower ends of the inferior vena cava, and inserting disinfected medical conduits into the portal vein, the biliary tract and the hepatic artery vessel; filling the conduits with perfusion liquid, allowing the perfusion liquid to fully enter the blood sinus system of the liver via the portal vein and the hepatic artery, continuously discharging macrophages and other immune cells containing a great number of toxins, blood and harmful substances, and discharging bile via the biliary tract system; and when the fresh liver turns white from blood red, taking off the conduits, thereby finishing treatment of the liver. The animal liver treated by using the method is maximally prevented from damage to the cell tissue of the liver, and can remove toxins, blood and harmful substances in the liver, which guarantees safety in subsequent eating of the liver.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for cleaning and detoxifying fresh animal livers and preserving freshness of cell tissues. Background technique [0002] The nutritional value of animal liver is high, such as pork liver, its nutritional content is more than 10 times that of pork. The content of vitamin A in animal liver exceeds that of milk, eggs, meat, fish and other foods. It can protect eyes, maintain normal vision, prevent dry eyes and fatigue, help children's bone development, promote skin tissue repair, and treat night blindness. function. In addition, there is vitamin B2 in animal liver, which can maintain healthy skin color, maintain normal growth and reproductive function, enhance the immune response of the human body, resist oxidation and prevent aging. Animal liver is also rich in protein and animal iron, which is a better nutritional food for children with nutritional anemia. However, the a...
