① The helical structure of collagen macromolecules and the existence of crystalline regions make it have certain thermal stability;
② Collagen shows strong toughness and strength due to its natural compact fiber structure, which is suitable for the preparation of film materials;
③ Maximum collagen is used to make edible packaging materials such as casings. Its unique feature is that during heat treatment, with the evaporation and melting of water and oil, the shrinkage rate of collagen is almost the same as that of meat. Other edible packaging materials have not been found to have this quality;
④ Because the molecular chain of collagen contains a large number of hydrophilic genes, it has a strong ability to combine with water, which makes collagen can be used as filler and gel in food;
⑤ Collagen swells in acidic and alkaline media, and this property is also applied to the processing technology of preparing collagen-based materials.
Collagen is used as a functional health food: it can prevent cardiovascular diseases
Studies show that collagen can reduce blood triglycerides and cholesterol, and increase some essential trace elements that are lacking in the body, thus keeping it in a relatively normal range. It is an ideal food for reducing weight and blood fat. In addition, collagen is unique in assisting the body to excrete aluminum and reducing aluminum accumulation in the body. Aluminum is harmful to human body. Studies have shown that the increasing number of Alzheimer's disease is related to the intake of aluminum. At the same time, Japanese esmay long-acting oligopeptide collagen has the effect of accelerating the production of hemoglobin and red blood cells, which can improve circulation and is beneficial to coronary heart disease and ischemic encephalopathy.
Collagen can make blood vessels work normally, so it is closely related to the prevention of arteriosclerosis and hypertension. Cancer cells are a foreign body to living beings, and collagen will wrap cancer cells to prevent them from increasing or transferring. It is suitable for severe patients such as diabetes and kidney patients to ingest high-quality and high-protein health food.
It can be used as a calcium-supplementing food
Hydroxyproline, the characteristic amino acid of collagen, is the carrier of transporting calcium from plasma to bone cells. Collagen in bone cells is the adhesive of hydroxyapatite, which is isomorphic with hydroxyapatite to form the main body of bone. Therefore, as long as enough collagen is ingested, the normal body's calcium intake can be guaranteed, and collagen can be made into health food for supplementing calcium.
Collagen is an important component in human bones, especially cartilage. Collagen is like a net full of small holes in bones, which will firmly retain the calcium that will be lost. Without this net full of small holes, even if excessive calcium is added, it will be lost in vain. Usually, 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 8%. For sports people, the constant and severe wear and tear of joints will form cartilage damage, which will not be recovered in a short time or even permanently. For the average person, after the age of 25, the collagen in the body begins to gradually lose, especially for women, because of the hormonal imbalance caused by age, the loss rate is several times faster than that of men. Therefore, the best way to maintain the health of joints and bones is to supplement calcium and collagen in time.
It can be used for special people
The root of gynecological diseases comes from endocrine disorders. Collagen can improve the troubles of gynecological diseases, while menopausal women need collagen to supply their needs, so that menopausal women can face various discomforts more easily.
Collagen contains a large amount of glycine, which not only participates in the synthesis of collagen in human body, but also acts as a central nervous system inhibitory transmitter in brain cells, so as to have a sedative effect on the central nervous system, and has a good therapeutic effect on anxiety and neurasthenia. Collagen food can inhibit protein's coagulation caused by gastric acid in the stomach, thus facilitating the digestion of food, inhibiting the secretion of gastric acid and gastric collagenase, alleviating the pain of patients with gastric ulcer and promoting the healing of gastric ulcer.
Collagen is the receptor of amoeba cells, which is responsible for the important function of body immunity, to clean foreign bodies, so it is very helpful to prevent diseases.
used as food additive
used as meat improver in meat products, gelatin, the hydrolysate of collagen, destroys its original compact supercoiled structure by destroying the hydrogen bond in collagen molecules. Small molecules with loose structure are formed, which can improve the tenderness of connective tissue and make it have good quality when added to meat products; Increasing the content of protein+not only has good taste but also is nutritious. Meiuenet et al.' s research shows that when the amount of collagen is 2% and water is about 2%, the sausage has the best sensory, texture and taste (lubricating feeling). At the same time, collagen, like other protein, has good dyeability. According to the needs of products, it can be dyed into pink color similar to muscle tissue with food pigments such as monascus, which is easy for consumers to accept.
Frozen food
Gelatin can be used as an improver of frozen food and as a jelly. It has a low melting point, is easy to dissolve in hot water, and has the characteristics of melting in the mouth. It is often used as meal jelly, grain jelly, jelly and so on. In the production of ice cream and ice cream, adding appropriate amount of gelatin can prevent the formation of coarse grain ice crystals, keep the texture fine and slow down the melting speed. The dosage of gelatin in ice cream is generally .25% ~ .6%.
Beverage
Fish gelatin is recognized as the most advanced clarifier in the world. In the beer and wine industries, fish gelatin and gelatin can be used as settling and clarifying agents, which can achieve very good results and the product quality is very stable. It also plays the role of thickener, emulsifier, stabilizer and clarifier in the process of fruit wine brewing. In the production of tea drinks, gelatin can prevent the turbidity caused by long-term storage of tea drinks and improve the quality of tea drinks.
dairy products
Collagen polypeptide can be widely used in liquid dairy towels such as neutral milk drinks, acidic milk drinks, fresh milk, yogurt, etc., and has the effects of anti-whey precipitation, emulsion stability, etc. It can also be added to milk powder, which can not only improve the nutritional value of milk powder, but also enhance the functionality of milk powder, accelerate bone development, enhance intelligence and improve the immunity of the body.
Cake candy
Collagen polypeptide can be added to bread, the addition amount is 3% ~ 5%, which can prolong the aging time of bread and improve the volume and softness of bread. Gelatin has the function of absorbing water and supporting skeleton. After its particles are dissolved in water, they can interweave into a net structure. After coagulation, sugar and water can be filled, so that soft candy can keep a stable shape and will not deform under a large load, which improves the nutritional value of candy and can develop low-calorie candy. Can be used as food packaging materials
artificial casing
In recent years, the proportion of various sausage products in meat products is increasing, and natural casing products are seriously lacking. Researchers are committed to the development of substitutes. Collagen casing with collagen protein as the main ingredient is a nutritious and high-protein substance. In the process of heat treatment, with the evaporation and dissolution of water and oil. Collagen has almost the same shrinkage rate as meat food, but other edible packaging materials have not been found to have this quality. Secondly, collagen itself has the function of immobilized enzyme. Can improve the flavor and quality of food. Especially sausage products. The artificial collagen casing also has the characteristics of good taste, high transparency and simple manufacturing process, which is beneficial to mass production and has good development prospects.
packaging film
collagen can be used as an inner packaging film such as preserved fruit and candied fruit, supplemented with additives such as glycerol and caCl2 _ 2 to improve the mechanical properties of the film, which is not only beautiful but also has good mechanical properties, and is also a nutritional carrier. Edible collagen packaging film generally has good tensile strength, heat sealability and high gas, oil and moisture resistance. Can be widely used for the preservation of various foods.
coating material
gelatin as coating material has many advantages on food surface:
① avoiding food oxidation and inhibiting Maillard reaction between amino acids and sugars;
② preventing powdery and granular sugar foods from moisture absorption and caking;
③ make the food surface shiny;
④ As a stabilizer, it can prevent the product from shrinkage and deformation;
⑤ it has fresh-keeping function. Adding a certain amount of gelatin solution to the sugar solution soaked in fruits and vegetables can form a protective film on the surface of fruits and vegetables, which can ensure the natural flavor and freshness of food.
⑥ prevent food spoilage. Extend the shelf life of food;
⑦ improve the preservation of volatile food ingredients;
⑧ adjust solubility, and so on.
As an important natural resource in protein, collagen is widely used in biomedicine, food health care, cosmetics and textile industry. Its good biocompatibility and biodegradability make it have broad application prospects in food industry.
the role of collagen in other parts of the human body
1. The bones are hard and elastic, so as not to be loose and fragile. Bone contains calcium, which will cause tooth lesions, tooth decay and periodontal disease when the calcium contained in teeth is lost, and lead to osteoporosis when bone calcium is lost. Collagen can combine calcium with bone cells without loss. The loss of collagen in bones will also reduce the amount of calcium in bones. At this time, it is not easy to improve this osteoporosis phenomenon if only the calcium intake is increased, because calcium cannot be kept in bones, and eating more calcium will also lose it, mainly because the amount of collagen has been reduced. Therefore, in order to keep the bone, it can be taken from food or supplemented by collagen health food. The ratio of collagen to elastin in dermis is about 45: 1, while collagen in bone accounts for about 2%. In skin and bone, collagen is the main protein component, and 8% is collagen in terms of total protein mass in bone. Because it contains collagen, bones and teeth are hard and elastic. Generally, animal bones and muscles also contain a lot of collagen, which is called "bone collagen". Collagen and gelatin can be extracted from animal bones and muscles and can be used in medicine and industry. 2. Collagen can make eyes transparent and cornea transparent. Cornea is one of the important structures in the eye, and the collagen fibers contained in it are arranged regularly, which not only allows light to pass through, but also makes the cornea transparent because of the special arrangement of collagen fibers. Because collagen is the main component of cornea, protein, the contact lens made of collagen is very suitable for human body, that is, it has high physical fitness, and its water retention is better than that of contact lenses made of other materials.
3. Muscle that promotes muscle cells to connect and has elasticity and luster is mainly composed of myofibrillin and myosin, and cells are bonded by collagen, which is also one of the body building materials. The three-dimensional skeleton formed by collagen molecules can keep the body in good posture and present proper softness. When eating beef, there is often a hard [beef tendon], and the main component is collagen.
fourth, protect and strengthen the visceral function. The main internal organs and tissues of human body contain collagen, and collagen is below the epidermal structure of these organs, whose greatest function is to protect and strengthen organs, such as stomach or intestine. When eating pig's brain or liver, it often feels unusually soft, not as hard and elastic as pig's feet, mainly because these organs contain less collagen. Nevertheless, collagen is still an indispensable component of these organs.
5. Support and moisturize the skin. Collagen is the main component of the skin, accounting for 7-8% of the dry weight of the skin, which is called "soft gold of the skin" by experts. The role of collagen in the skin is equivalent to a fine elastic net, which firmly locks moisture and supports the skin. With the increase of age, the loss of collagen will lead to the rupture of the elastic net and the atrophy of skin tissue, resulting in skin dryness, wrinkles, spots and other aging phenomena. Yufubao bi-directional collagen has the characteristics of directionally supplementing skin collagen, reaching the basal collagen layer of the skin, replenishing the lost collagen in time, and keeping the skin moist and tender.
Product features
Collagen powder is a small molecular weight collagen, extracted from natural materials, and contains no preservatives, dyes and spices. The denaturation temperature is low, collagen fibers are easy to disperse, and the molecular weight is very low. Compared with other collagens, collagen powder is fast to digest and absorb, and contains no fat components.
The quality of collagen powder is easy to distinguish with naked eyes, because it has no other ingredients, and it has anti-cancer effect, promoting blood coagulation and hemostasis, and can also generate antibodies against pathogens invading the body, thus enhancing the body's immunity. When taking a large amount of collagen, it can be excreted as nitrogen decomposition products in the form of urine and sweat, and will not form accumulation in the body. In addition, when taken together with other foods or materials, the nutrient source will not be destroyed.
in addition, the slimming collagen powder not only has a good moisturizing effect, but also is easy to be absorbed by the skin, and its thermal stability is high, reaching 12°C .. The results of blood tests show that the concentration of amino acids in blood of people who ingest fish skin collagen every day is significantly higher than that before ingestion. This is because the human body can rely on amino acids absorbed by blood to rebuild collagen. Therefore, if patients with osteoporosis, osteoarthritis, allergic dermatitis or pollen allergy take collagen for a long time, they can enhance the functions of various tissues and effectively improve their symptoms.
Compared with collagen in traditional cosmetics, collagen powder has better moisturizing effect and is easier to be absorbed by the skin. In addition, oral administration can make the body younger. Nowadays, quantitative intake of collagen powder has become an indispensable part of healthy life. Especially, in the coming aging society, it is a kind of green health nutrition with special significance.
