Technical Field
The invention relates to the field of preparation and application of tablets, in particular to preparation and application of squid melanin-chelated calcium tablets.
Technical Field
Calcium is an essential element for living beings. Ca is useful in human body in muscle, nerve, body fluid and bone2+A bound protein. Calcium is the main inorganic component of human bone and teeth, and is also an essential element for neurotransmission, muscle contraction, blood coagulation, hormone release, milk secretion and the like. Calcium participates in metabolism and must be supplemented every day; the deficiency or excess of calcium in human body can affect growth and health. Calcium is the most abundant inorganic salt component in human body, and the total amount of calcium in healthy adult is about 1000-1300 g, and about 1.5% -2.0% of body weight, wherein 99% of calcium exists in bone salt form in bone and teeth, and the rest is distributed in soft tissue, and calcium in extracellular fluid only accounts for 0.1% of total calcium. Bone is the main site of calcium deposition, soIt is called "calcium pool". Bone calcium exists mainly in two forms of amorphous calcium hydrogen phosphate and crystalline hydroxyapatite, and its composition and physical and chemical properties change with physiological or pathological conditions of human body. More calcium hydrogen phosphate is contained in the new bone than the old bone, and the bone is gradually changed into hydroxyapatite in the process of maturing. The bone keeps dynamic balance of bone calcium and blood calcium through continuous osteogenesis and osteolysis.

Example 4:
on the basis of example 3, without changing any data of example 3, the weight parts of the polypeptide chelating ferralium/D-4-hydroxyphenylglycine in the chelating step were set to 0.03/0.03, 0.04/0.02, 0.045/0.015, 0.04/0.01, 0.05/0.01, 0.03/0.005, 0.042/0.006, 0.04/0.005, 0.045/0.005, 0.05/0.005, i.e., the weight ratio of the two was 1:1, 2:1, … …, 9:1, 10: 1.
Measuring the content of calcium ions in the solution after the chelation step in the examples 1 to 4 by using a spectrophotometry method, so as to obtain the chelation rate of the squid melanin chelated calcium, and arranging the chelation rates in the examples 1 to 3 into the values shown in the table 1:
TABLE 1 chelating ratio of calcium chelate from squid ink melanin in examples 1-3
| Example 1
| Example 2
| Example 3
|
Rate of chelation
| 60.5%
| 58.6%
| 68.5% |
From table 1, it can be seen that by controlling a proper chelating condition, the chelating rate of squid ink melanin to calcium ions is very high, and can reach 55% -70%, the higher chelating rate improves the utilization efficiency of squid ink, increases the amount of calcium ions absorbed by squid ink melanin, and improves the calcium content of squid ink melanin chelated calcium tablets, and particularly, after D-4-hydroxyphenylglycine is added in the chelating reaction of example 3, the chelating rate of squid ink melanin is improved by nearly 10% compared with examples 1-2 without D-4-hydroxyphenylglycine, which shows that the addition of D-4-hydroxyphenylglycine improves the absorption effect of squid ink melanin to calcium ions based on a certain unknown intrinsic mechanism.
The chelating rate of the polypeptide iron chelate agent and D-4-hydroxyphenylglycine in example 4 was measured in different weight parts, and the relationship between the chelating rate and the weight ratio is shown in FIG. 1.
As can be seen from fig. 1, there is a correlation between the chelating rate of squid melanin to calcium ions and the weight ratio of the polypeptide iron chelate to D-4-hydroxyphenylglycine, and the correlation exhibits a non-linear correlation; as can be seen from figure 1, when the weight ratio of the polypeptide chelated iron agent to the D-4-hydroxyphenylglycine is within the interval of 3:1-10:1, the chelated rate of the squid ink melanin to the calcium ions is higher than 60%, particularly, when the weight ratio of the polypeptide chelated iron agent to the D-4-hydroxyphenylglycine is 3:1 or within the interval of 7:1-8:1, the chelated rate of the squid ink melanin to the calcium ions reaches more than 80%, which may be because the D-4-hydroxyphenylglycine acts on the polypeptide chelated iron agent to release certain unknown substances to change the chelated internal environment, thereby improving the adsorption capacity of the squid ink melanin to the calcium ions and improving the chelated rate thereof, the internal mechanism thereof is not clear, the higher chelated rate of the squid ink melanin to the calcium ions is helpful for improving the content of calcium in the tablet, meanwhile, the utilization value of the black pigment of the squid ink is enhanced.
