The present invention relates to the field of medicine, particularly to a kind of high-affinity shrimp shell calcium powder and its preparation method.
Background Technology
The calcium deficiency disease in dogs is a clinical commonly encountered disease.
Calcium deficiency can be divided into acute acalcerosis and chronic acalcerosis; wherein, the main manifestation of acute acalcerosis is puerperal tetany, and the commonly encountered chronic calcium deficiency diseases mainly consist of rickets, osteoporosis in dogs, as well as nutritional and secondary hyperparathyroidism, etc.
In recent years, with the rapid development of the night-time economy and barbecue industry, crayfish became one of hot products of the night-time economy and barbecue industry.
Since the market demand for crayfish has increased rapidly, the crayfish processing industry was stimulated to develop rapidly.
However, the edible proportion of crayfish is low, for adult crayfish, it just reaches 20-30%, while the head, which is usually discarded directly or simply processed into animal feed, accounts for as high as 70% of the crayfish.
Thus, improper use of crayfish heads would cause serious pollution problems or result in waste of resources easily, which has become a main obstacle that limited the development of crayfish processing enterprises.
Currently, shrimp shells are mostly processed into animal feed simply, and only a few of them are used to extract and prepare chitin, so that result in a serious waste of resources.
As a calcium resource, the difficulty in the development of shrimp shells focused on two aspects.
One is the calcium in shrimp shells are relatively hard, thus, due to the taste is not good, they are hard to be applied in the food industry after being processed into calcium powder; the other is shrimp shells are rich in ingredients including calcium and chitin, etc. have poor compatibility with proteins, starches, and polysaccharides, etc., thus, when the proteins, starches, and polysaccharides, etc., are used as base stocks to prepare dosage form, the addition amount would be limited, which can affect the applications.

Comparing the embodiment 1 with the embodiment 4, although the affinity of the food matrixes has increased, the increased amount of surface modifying agent used would result in the decrease of effective content of calcium in the product. By comparison, for the range of the embodiment 3, not only the high calcium content can be validly guaranteed, but also the affinity between the product and the food matrixes can be absolutely secured.
Comparing the embodiment 3 with the embodiment 6, it can be seen that the acid treatment step has a significant effect on the removal rate of heavy metals, while the impact on the affinity between the final product and the food matrixes is limited.
The text above has described preferred embodiments of the present invention in detail; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, a variety of simple variations can be made to the technical scheme of the present invention, including the combination of various technical features in any other proper ways.
