Applications of Oyster Calcium Carbonate_Industrial Additives

Application overview of oyster calcium carbonate

Oyster calcium carbonate is prepared from the shells of marine organisms oysters through high-temperature calcination and electrolysis activation. Oyster shells contain more than 90% calcium carbonate. They appear as white powder and are rich in calcium and manganese needed by the human body. , zinc, silicon, phosphorus and other trace elements needed by the human body, oyster calcium carbonate is superior to traditional calcium agents in terms of solubility and absorption. Oyster calcium carbonate, also known as “active calcium”, originated in Japan as a calcium supplement. The product of Uchida and Han Pharmacy KH Company in Japan is named calcium carbonate “Xinlixiu”, which is an excellent natural calcium with biological and chemical activity. source. Nowadays, oyster calcium carbonate is widely used in European and American countries. It has been included in the pharmacopoeia of China, the United States, the United Kingdom, and Japan, and is used clinically as a calcium supplement preparation.

Application and preparation of oyster calcium carbonate

Take 1 molar mass of active calcium that meets the original drug standard, put it into a double-layered sealed stainless steel container with a sandwich (it can be a rotary vacuum dryer or a mixer), and directly pass the pressure gauge and pressure reducing valve from the top. Fill in food grade or pharmaceutical grade carbon dioxide gas (CO2), the amount of carbon dioxide gas (CO2) is 1 to 1.5 molar mass, use cold or hot water to control the temperature in the interlayer to 35 to 90°C, and allow for a full reaction of 3 to 24 hours. In the future, pharmaceutical grade oyster calcium carbonate that meets national drug standards will be available.

Pharmacological effects

This product participates in the formation of bones and the reconstruction of bone tissue after fracture, maintains nerve conduction and muscle contraction, reduces the permeability of capillaries, and maintains the normal osmotic pressure of capillaries. Participate in the coagulation mechanism and maintain blood acid and alkali balance.

Indications

For calcium supplementation in children, pregnant or lactating women, menopausal women and the elderly.

Applications of oyster calcium carbonate

1) Prepare an antibacterial pineapple beer. The prepared pineapple beer not only has a high antibacterial effect, but also has a significant antioxidant effect. Adding corn stalks, diatomaceous earth and oyster calcium carbonate during the pineapple, watermelon and strawberry juice extraction process, on the one hand, improves the juice extraction efficiency, and initially absorbs the oxidase in the juice, enhancing the antioxidant effect. On the other hand, the oyster Calcium carbonate generates soluble calcium under the dual effects of fruit acid and juice extraction, which reduces the occurrence of gastrointestinal adverse reactions and has the effect of calcium supplementation; the addition of shiitake mushrooms and enoki mushrooms during the fermentation process improves the antioxidant properties of the resulting pineapple beer , while increasing its alcohol output; using Andrographis paniculata, green tea, cassia seed, orchid herb and celandine to prepare a traditional Chinese medicine liquid, which, after being added to pineapple beer, produced an antibacterial effect and had excellent antioxidant properties.

2) Prepare a calcium supplementary feed additive for livestock and poultry, including the following raw materials: oyster calcium carbonate, calcium gluconate, calcium lactate, zinc gluconate, VD3, folic acid, pantothenic acid, niacin, biotin, yeast selenium , sucrose, sour agent, trace elements, emulsifier, co-emulsifier, antioxidant, preservative, carrier. The present invention provides a formula and a manufacturing method of a calcium supplementary feed additive for livestock and poultry. The additive can prevent and treat systemic bone porosis, reduced bone density, and inability to stand due to calcium deficiency in chickens, ducks, geese, and pigeons. It can significantly increase egg weight and eggshell hardness, improve eggshell and egg yolk color, and effectively prevent and control caged chickens from producing broken shell eggs, soft eggs, white-preserved eggs, sharp-preserved eggs, etc.; effective Prevent and treat “egg-laying fatigue syndrome”; used in the youth of laying poultry, so that the tibia and hip bones are fully developed and the weight reaches the standard; used for the bone development of meat poultry, making the skeleton wider and increasing the weight; at the same time, it can also supplement vitamins, selenium, Trace elements, etc., while having a sweet and sour taste.
