Description

A kind of ultra micro high calcium deep-sea collagen powder and its preparation method and application
Technical field
The present invention relates to a kind of ultra micro high calcium deep-sea collagen powder, further relates to a kind of preparation side of ultra micro high calcium deep-sea collagen powder Method and application.
Background technology
Calcium is one of indispensable nutrient of human body, if without calcium, lived can not be produced.Calcium is Most abundant mineral matter in human body, the whole life process of human body is participated in, be human life sheet.From bone formation, contraction of muscle, Heartbeat, the thinking activities of nerve and brain, until the growing of human body, dispelling fatigue, brain tonic and intelligence development and delaying to decline Wait for a long time, it may be said that all motions of life all be unable to do without calcium.Daily intake that calcium amount is enough, the new old of human normal could be maintained Metabolism, adaptive faculty of the enhancing human body to living environment.Calcium can strengthen the endurance of people, make one energetic, mental toughness.Internal calcium Abundance, it could effectively prevent cerebral hemorrhage, cancer and cardiopathic generation, be advantageous to have good health and a long life.
Substantial amounts of calcium in bone and tooth, it is the main component for forming body tissue, and bone is had certain hardness, rises The effect of support body.Calcium in blood, have and maintain brain and cardiac function normal, bear all normal cell physiology situations Regulation and the effect such as secreting hormone, solidificating blood, cell there is no calcium just can not survive.Effect of the calcium in human body is as follows:
1) existence and the function of cell are maintained.Cell division is bred, and number is cumulative, changes function gradually with unicellular, all Need the participation of calcium.Calcium wakes up cell and started working, otherwise cell is always maintained at sleep state from extracellular entrance.Calcium enters Cell, electric wave is sent, and be covered with the nerve fibre of whole body, form human body information network, the input of information passes through the activity of calcium Pass to parts of body.EndocrineAlso blood, the transmission information into organ must be passed through by calcium during gland cell secreting hormone.Cell Individual feature and the network that intercommunicates can not all lack calcium, or even aging, disease, the dead equilibrium theory that can use calcium It is bright.Fully take in calcareous, cell can just keep fit active.
2) participation is nervimuscular stress process.On a cellular level, as the lotus root between N&M Excitation-contraction Join the factor, medical education net, which is collected, to be arranged | promote the conditioning agent of neurotransmitter release and endo-exocrine gland secreting hormone, conduction god Through impulsion, heart beat rhythm is maintained.Calcium has sedation, and when calcium concentration reduces in body fluid, the excitability of N&M increases, There is Spontaneous Contraction in muscle, is had a convulsion when serious, when calcium concentration increase in body fluid, then suppresses the excitement of N&M Property.
3) calcium maintains to maintaining internal acid-base balance and the internal many biochemical processes of regulation is required, it can promote body The activity of interior a variety of enzymes, it is a variety of zymoexciters, such as lipase, amylase are by regulation of calcium.When internal calcium deficiency When protein, fat, carbohydrate can not make full use of, cause malnutrition, apocleisis, constipation, hypoevolutism, immunologic function Decline.
4) calcium is a kind of clotting factor, plays catalytic action when prothombin is fibrin ferment, then fibrin ferment makes Fibrinogen, which is polymerized to fibrin, makes blood clotting.Calcium is combined with phosphatide, maintains the integrality and permeability of cell membrane.Calcium Ion can make body fluid normal through cell membrane, commonly used to alleviate changing for the membrane permeability pressure caused by the diseases such as allergy Become.
Calcium deficiency can cause more than 100 kinds of disease, such as:
1st, bone metabolic disease:Osteoproliferation, osteoporosis, cervical spondylopathy, scapulohumeral periarthritis, rickets, osteomalacia, caput femoris necrosis Deng;
2nd, endocrine disease:Hyperthyroidism, diabetes, adrenal gland, obesity etc.;
3rd, it is cardiovascular:Atherosclerosis, hypertension, heart disease, miocardial infarction etc., pregnancy-hypertension syndrome etc.;
4th, nervous system:Neurasthenia, hyperactivity, dementia, the cerebrovascular, cerebral hemorrhage, epileptics etc.;
5th, digestive system:Peptic ulcer, hepatic sclerosis, gastrointestinal convulsion, hemorrhoid etc.;
6th, respiratory system:Bronchial spasm, pneumonia, pulmonary tuberculosis, chronic obstructive pulmonary disease etc.;
7th, urinary system:Oedema, acute nephritis, acute or chronic renal failure, stone in urinary system etc.;
8th, reproductive system:Infertility, dysmenorrhoea, climacteric syndrome etc.;
9th, sense organ:Myopia, cataract, brothers are split, Hearing, skin disease, eczema, Zu Xian, Shou Xian etc.;
10th, immune system:Dermatitis, rheumatism, rheumatoid, arthritis, allergy skin disease, CTD etc.;
11st, hematological system:Anaemia, hemophilia etc..
Calcic is about 1200 grams in adult body in the case of normal, wherein about 99% is present in bone and tooth, mainly Exist in the form of hydroxyapatite crystal, maintain bone and tooth that there is hard structure and support, in addition about 1% calcium Chang Yiyou From or the ionic condition of combination be present in outside soft tissue cells and in liquid and blood, play the work of important regulation of physiological functions With being referred to as miscible calcium pool.Miscible calcium pool maintains dynamic equilibrium with the calcium in bone, i.e., the calcium in bone is constantly from osteoclastic thin Discharged in born of the same parents into miscible calcium pool, ensure that the concentration of plasma calcium remains constant;And the calcium in miscible calcium pool is constantly deposited on Gegenbaur's cell.The renewal of this calcium, adult are about daily 700 milligrams, and the renewal speed of calcium slows down with advancing age, The bone of child updates once per 1-2, and the bone about 10-12 of adult could update once.After male about 18 years old, bone Length start stabilization, more earlier, the rate of development of height tapers off women, but the density of sclerotin continues to increased numbers Year.Generally after 35 years old, the content of the inorganic substances such as calcium in bone gradually decreases, such as insufficient supplement calcium material, can Phenomena such as serious disease including osteoporosis can occur caused by calcium deficiency, women overweights male.For all one's life of people For replenish the calcium and can not all lack.
The composition of bone tissue can be divided into 3 kinds of organic species, inorganic salts material and moisture.Organic species are by collagen egg In vain, glycoprotein, polysaccharide, bone matrix, collagenous fibres etc. are formed, including cell component and cytoplasm.Cell component includes skeletonization Cell, osteoclast and osteocyte;Cytoplasm is made up of bone matrix and collagenous fibres.Organic matter makes bone have necessarily tough Property.The inorganic matter of bone is also known as bone salts, and main component is calcium and phosphorus.Bone salts accounts for the 75% of compact bone substance total amount, mainly with hydroxyl The form of base apatite crystal is present.Bone salts is combined with collagenous fibres and matrix makes bone have certain degree of hardness.Calcium in inorganic matrix There is provided bone hardness and pressure, the collagenous fibres in organic substrate provide support and tension force.
