The natural world is divided into two major categories of organisms: one is crustaceans, such as: fungi, insects, crustaceans; the other is fibrous, such as: vertebrates (people, livestock, fish), plants and so on. Looking at the long history of special evolution, scientists have found that the life resilience of crustaceans to life is much greater than that of fibrous organisms. For example, chitin-containing insects grow and reproduce in extremely harsh environments, sea crabs and turtles live endlessly in pollution, fungi can colonize in large quantities as long as there is air and moisture, but fibers are not so strong, dinosaurs are extinct, pandas are worried, golden snub-nosed monkeys are endangered, fish adaptability is extremely poor, water quality is almost dead, large forests are disappearing, and more modern diseases of human beings.
The huge difference in the survival resistance of "crustaceans" and "fibrous organisms" has aroused the strong interest of scientists, and experts at home and abroad predict that if the chitin (chitosan) existing in crustacean organisms is used to use its bactericidality, cell activation, epidemic prevention, and application to human health and ecological protection, it will save the life of the entire earth in the 21st century.
In today's modern disease spread, chitin attracted much attention, by no means accidental, although it is not a panacea, but as a functional health food, "chitin" is about to trigger an unprecedented medical revolution, it can be said that the twenty-first century is the era of chitin, the heyday of carapace is coming.
Chitosan is a natural polymer animal food fiber, is the only alkaline polysaccharide with cationic properties found so far, the World Medical Congress called "the sixth element of life of the human body". It is converted into low molecular weight polysaccharides under the action of human lysozyme, absorbs human blood, and has a strong physiological effect. The product's N--- acetyl glucosamine is the basic component of the important substance hyaluronic acid human chondroitin, so it is non-toxic to the human body, non-tertiary, easy to absorb degradables, no antigenicity, non-sensitization, no hemolysis, no rejection, and good compatibility with body tissues.
Generally speaking, the ingredient contained in the shell of insects and crabs is called chitin, and it needs to be decomposed into chitosan through the decomposition of an enzyme in the soil or plants before it can be used by the human body. Since chitin cannot be dissolved in water or in acid, it cannot be directly absorbed by the body. Therefore, when people eat crabs, shrimp and insects directly, they cannot get crustacean. However, after a series of biochemical treatments, the acetyl group in the chitin molecule is removed to obtain a chitosan (chitosan), which differs from chitosan in that the molecular structure does not contain acetyl, but amino. A very important property of chitosan is that it can be soluble in most dilute acids, when people eat, chitosan is dissolved by gastric acid, and then in the intestine by the body's lysozyme, chitin decomposition enzyme degradation into low molecular weight substances after being absorbed and utilized by the body. Because there is a very active amino group (+NH2) on the chitosan molecule, the hydroxyl group (-OH) on its ortho position is also activated, and a variety of harmful substances in the body will be adsorbed or combined by these two active groups and excreted, so it is called "human environmental protection agent".
Chitosan is the use of Arras deep sea cold water grown snow crab as raw materials, after the deacetyl group of biological engineering technology refined into a natural alkaline polysaccharide, it into the human body can improve the human acidic environment, eliminate toxins in the body, create a physique that is not easy to get sick, strengthen the body's immunity, carry out a full range of physiological regulation, as Chinese medicine said "positive qi memory, evil can not be flat".
Chitosan, a heaven-given food, embodies the crystallization of human wisdom and has finally become a treasure to protect human health today. When eaten as a health care product and clinically applied, it should put aside personal prejudices and wealth interests, maintain respect for human beings and life on the earth, and understand and apply it with a sincere attitude, so that it can truly become a protector of human health.
