See you tomorrow ~ Why can Flammulina velutipes last for a long time?

What do you like to add to hot pot in winter? A few days ago, the store launched the year-end hot pot award. I best describe the characteristics of Flammulina velutipes with the slogan "Legend of Immortality-See you tomorrow". It can not be cooked for a long time and can still see the complete shape after defecation. Poke the netizens to win the championship, winning the hot pot ingredients such as cabbage, Yan jiaozi, and prince noodles! However, why does Flammulina velutipes have such strong toughness? Let the nutritionist tell you!

Flammulina velutipes is not rotten and difficult to digest. The immortal legend is worthy of the name.

Flammulina velutipes has low calorie and high nutritional value, which helps to stabilize blood sugar, reduce cholesterol, help to lose weight, promote intestinal peristalsis and enhance immunity. It is the best partner of the "hot pot party", because it is crisp but not rotten, and it is not rotten for a long time. However, almost everyone has the experience of eating Flammulina velutipes and still seeing the whole Flammulina velutipes when defecating the next day. The legend of immortality is worthy of the name!

The reason why Flammulina velutipes can't be boiled for a long time and become immortal lies in "water-insoluble fiber" and chitin? More chitosan. The key to the immortality of Flammulina velutipes: water-insoluble fiber!

Hou, director of the Nutrition Department of St. Martin's Hospital, said that the key to the long-term cooking of Flammulina velutipes without deterioration lies in "water-insoluble fiber" and chitin? Chitosan is rich in resources, unlike water-soluble fibers, which are easy to be boiled and then cooled and frozen, and water-insoluble fibers are not easy to be boiled. Some people attribute the long-term non-decay of Flammulina velutipes to "chitin", which is similar to cellulose, belongs to polysaccharide and has antibacterial effect on intestinal bacteria. Chitin usually exists in the cell wall of fungi and the exoskeleton of arthropods (such as shrimp and crab) or insects.

Flammulina velutipes found in feces does not mean that they are not digested, but only choose "indigestible fiber" to present healthy functions. The main function of water-insoluble fiber is to promote intestinal peristalsis, increase the volume of feces and excrete toxins from the body together.

In addition, human beings are omnivores, unlike herbivores (such as cattle and sheep) whose stomachs can decompose fiber, and water-insoluble fiber can not be decomposed by acid-base digestive enzymes such as gastric acid, bile and pancreatic juice in the small intestine, so it is easy to be excreted in its original form after eating.
