Collagen is  added to jelly, fudge and other foods. Collagen is also claimed to be added to some cosmetics. It can be seen that collagen is closely related to everyday life, but people seldom pay attention to it.

Collagen is an important component of human skeleton, especially cartilage tissue. Collagen is like a web of holes in the bones, which retains the calcium that is about to be lost. It is tough, slightly elastic and strong in tension. Without this net full of small holes, even if the excess calcium is added, it will be lost in vain. Generally, inorganic substances such as calcium, magnesium and phosphorus account for only a few percent of the total amount of bone, while organic substances such as collagen account for more than 80 percent. For sports people, the continuous severe wear and tear of joints will lead to cartilage damage, which will not be restored in a short time or even permanently. For the general population, after 25 years of age, collagen in the body began to gradually lose, especially in women, due to age-related hormone imbalance in the body, the loss rate is several times faster than that of men. Therefore, the best way to maintain joint and skeletal health is to replenish calcium and collagen in time. In addition, collagen is easily digested by gastric juice and melted into gelatin in boiling water with double diopter.

The location of collagen. Collagen is a kind of animal bioplasm, which plays a role of binding function in animal cells. It widely exists in animal cells. It is also the most important component of extracellular matrix and the most important structural protein in animal connective tissue.

About 16% of the body's components are protein, and 35-45% of the protein is collagen, so there are about 3 kilograms of collagen in the body of adults, mainly in the skin, muscles, bones, teeth, viscera (such as stomach, intestine, heart, lung, blood vessels and esophagus) and eyes.

Collagen exists in animal skin and bone, such as pig skin、tendon、chicken  skin and bone also contains a large amount of collagen.

Although many sources of collagen are produced, industrial production mainly comes from skin, bones and muscles of cattle, pigs and fish.

Pig feet, skin and bones have a layer of viscous gelatin, which is soft and elastic to eat and quite viscous. Many drugs are wrapped in a layer of capsules, and the capsules are made of gelatin (gelatin). Gelatin is a kind of biochemical substance of collagen with similar structure and is a deformed product of collagen.

The way to distinguish

Six ways to identify the advantages and disadvantages of collagen:

1. hand kneading method: powder is fine without impurities.

2. nose smell method: we must see collagen powder, good quality is no smell.

3. eye view: take appropriate amount of pure powder and dissolve with water, and can quickly dissolve, limpid and no other impurities.

4. taste method: drink the taste of the entrance light, almost tasteless.

5. Selection method: High quality small molecule collagen peptide, from raw material selection to production are strictly controlled.

6. Skin test: Apply a small amount of liquid on the back of the hand or face to see if it is fully absorbed after a short time. There is no white crystal or foreign body residue on the surface.
