Description
Technical Field
The invention belongs to a nutrient element supplement, and particularly relates to a series of composite strontium-calcium nutrient element supplements.
The invention also relates to a preparation method of the nutrient element supplement.
Background
Calcium is a well-known nutrient element essential to the human body. It is an important element of human bone marrow and teeth. It has many important physiological functions, and plays a pivotal role in the physiological processes of muscle stress, nerve impulse transmission, cardiac rhythm maintenance, blood coagulation, cell function, synthesis and secretion of protein hormones, release and activation of intracellular and extracellular enzymes, and release of synaptic neurotransmitters. The lack of calcium leads to various malfunctions in the life process and thus to pathological changes. For example, rickets seriously affect the growth and development of infants, and if the infants cannot be effectively treated in time, disabilities of different degrees are accompanied with the infants for a long time. As another example, osteoporosis has become a significant public health problem and threats to human health are ongoing. Because of the insufficient calcium intake of our country, the calcium supplement has been generally concerned by people for a long time.
At present, dazzling calcium supplement advertisements flood various publicity media in China, and some brand calcium supplements are popular in the market and are utilized by people. And new calcium supplements are emerging (chinese patent application No. 96116582, 93110481). However, there are two major chemical components of calcium supplements currently in use: (1) calcium supplements in inorganic form, such as calcium carbonate. (2) An organic form of calcium supplement, such as calcium gluconate. The calcium supplement can supplement calcium required by human body, and has effects in preventing and treating calcium deficiency. However, after careful study of the above calcium supplements, they have been found to have a common limitation of supplying calcium alone as a nutrient. Research results continuously reveal that people need a plurality of nutrient elements (including macro elements and trace elements), and particularly, the synergistic effect among the nutrient elements is considered to be important, so that the application of the compound nutrient element supplement achieves the effect of getting twice the result with half the effort. Strontium is not only an essential element for calcification of human bone marrow and teeth, but also has a special function of promoting calcification of bone marrow. However, the research on dietary intake and nutrition hygiene indicates that the intake of strontium is obviously insufficient for people in China. Based on the analysis, the series of composite strontium calcium nutrient element supplements break through the serious limitation of a single calcium supplement and become a precursor of a new generation of calcium supplements.
Disclosure of Invention
The invention aims to provide a series of composite strontium calcium nutrient element supplements.
The invention also aims to provide a preparation method of the nutrient element supplement.
The invention is based on the following principle: (1) scientifically utilizes the complementary effect between strontium and calcium. Calcium is the major component of bone and teeth. Bone calcium is in dynamic equilibrium with what is known as the pool of miscible calcium, i.e., calcium in bone is constantly released from osteoclasts into the pool of miscible calcium, which is constantly deposited in osteoblasts. Strontium is a bone-friendly element and is mainly concentrated in places with vigorous calcification. Although strontium only accounts for 0.12% of bones, the special function of strontium is to promote calcification of bones, and the lack of strontium damages the calcification of bones and slows down the growth. The complementary effect of the strontium and the calcium is skillfully utilized, so that the calcium supplement has obvious effect. (2) The biological molecular vitamin C (ascorbic acid) is used as two metal ion carriers of strontium and calcium so as to improve the human body absorption rate of the strontium and the calcium. The vitamin C is an important biomolecule in the human body, and the vitamin C complex of the nutrient elements exists in the human body and directly participates in the metabolic process in the human body, so the vitamin C complex is easy to be absorbed and utilized by the human body, and the physical energy is saved. On the other hand, the composite strontium calcium nutrient element supplement does not introduce other useless or harmful anions into the human body. (3) The principle of simultaneous supplement of multiple nutrients. The composite strontium-calcium nutrient element supplement can simultaneously supplement calcium, strontium and important nutrient component vitamin C required by human body. Based on the principle, the invention creates a series of composite strontium calcium nutrient element supplements for the first time.
The chemical formula of the series composite strontium-calcium nutrient element supplement provided by the invention is as follows:
SrxCa(1-x)L2wherein x is more than or equal to 0.1 and less than or equal to 0.3; l is ascorbate, which has the chemical formula C6H7O6。
The raw materials used were as follows: strontium carbonate (SrCO)3) Chemically pure; calcium carbonate (CaCO)3) Chemically pure; vitamin C (C)6H8O6Ascorbic acid), biochemical reagents.
The series of composite strontium calcium nutrient element supplements break through the limitation of the traditional single calcium supplement and become a precursor of a new generation of composite calcium supplements. The nutrient element supplement has the following remarkable advantages: (1) scientifically utilizes the complementary functions of strontium and calcium, and has very outstanding calcium supplementing effect. Compared with single calcium supplement, the calcium supplement can achieve the effect of twice the result with half the effort. (2) Strontium is a component of human bone marrow, and is also an indispensable element for tooth calcification, and can promote calcification of exposed areas of teeth. And the strontium intake of Chinese people is far lower than the international standard. The series composite strontium-calcium nutrient element supplement can simultaneously provide calcium, strontium and important nutrient component vitamin C required by human body. (3) The strontium and calcium contents in the series of composite strontium calcium nutrient element supplements can be changed, so that a series of strontium calcium nutrient element supplements can be formed, and the requirements of people in different health states can be met.
The preparation process of the series of composite strontium calcium nutrient element supplements is simple and easy to implement. Preparing chemical composition of series composite strontium calcium nutrient element supplements (Sr)xCa(1-x)L2) Strontium carbonate, calcium carbonate and vitamin C are accurately weighed respectively. Adding water, and stirring to make the strontium carbonate into suspension. A suspension of calcium carbonate was also prepared. Dissolving vitamin C in water to obtain water solution. The suspensions of strontium carbonate and calcium carbonate were mixed and placed on a heated stirrer. Dropwise adding the vitamin C aqueous solution into the mixed suspension of strontium carbonate and calcium carbonate under the condition of continuous stirring. The preparation reaction temperature is controlled to be 30-40 ℃. The vitamin C, strontium carbonate and calcium carbonate are subjected to chemical reaction according to the following formula:
The preparation process of the series composite strontium calcium nutrient element supplement has the following advantages: (1) the preparation of the target product requires only one inorganic reaction. The preparation process is simple and easy to operate, easy to master and easy to industrialize. (2) The preparation of the target product does not need large and complex instruments and equipment, and only uses the simplest and most common equipment in general chemical preparation. Therefore, the industrialization is convenient, the investment is low and the effect is quick. (3) The preparation reaction of the target product is single, and no side reaction occurs. Besides the target product, only escaped carbon dioxide and water exist in the reaction product, so that the purity and yield of the obtained product are high, and no separation operation is needed.
