Problems solved by technology

The first and second types of calcium preparations have the following problems: they are generally difficult to dissolve, and some are highly alkaline and strongly stimulate the gastrointestinal tract; they contain heavy metals, such as lead and arsenic, which often exceed the standard; ionic calcium preparations are suitable for absorption in acidic environments. Therefore, a small section of the duodenum and jejunum is better absorbed, and the lower intestinal tract is alkaline, and calcium cannot be dissolved, making it difficult to absorb; ionic calcium is also easily interfered by dietary ingredients such as oxalic acid, affecting calcium. Absorption
At present, the calcium supplement preparation using amino acid chelated calcium as raw material has not been fully developed in China, and there is no report on the preparation of compound amino acid chelated calcium from freshwater fish bones

Embodiment Construction

[0014] The preparation steps of the present invention are: cleaning fish bones, steaming, soaking in sodium hydroxide, washing to neutrality, drying, pulverizing, extracting calcium in fish bone powder by acid hydrolysis, chelating calcium ions in fish bone powder with compound amino acids, and centrifuging to remove the calcium ions. solution, washed twice with absolute ethanol, centrifuged to take the precipitate, dried and pulverized to obtain the compound amino acid chelated calcium product.

[0015] The product is packaged in capsules, and each capsule contains: 1000 mg of compound amino acid chelated calcium, VD3200IU or 650 mg of compound amino acid chelated calcium, and 350 mg of casein phosphopeptide (content ≥ 21%). After testing, the total number of colonies in the product (cfu / g)≤3000, Escherichia coli (MPN / 100g)≤30, mold (cfu / g)≤50.

Abstract

The invention relates to a method for preparing compound amino acid chelate calcium from low-value freshwater fish bones. The method comprises the following steps: washing and steaming fish bones andthen soaking the fish bones in sodium hydroxide; then washing the fish bones to be neutral; drying and pulverizing the fish bones; extracting calcium in fish bone powder by an acidolysis method; chelating calcium ions in the fish bone powder by using compound amino acid; carrying out centrifugation to obtain clear liquid; washing an obtained product twice by absolute alcohol and then carrying outcentrifugation to obtain precipitates; and drying and pulverizing the precipitates to obtain a calcium acid chelate capsule product. The invention firstly adopts the fish bones which are by-products of processing low-value freshwater fishes to prepare the compound amino acid chelate calcium, thereby greatly improving the additional value of the by-products of the freshwater fishes. Proved by an animal experiment, the compound amino acid chelate calcium has thighbones calcium content of a rat of 32.81-43.41 and thighbones calcium retention rate of 5.30-16.30. If the compound amino acid chelatecalcium is matched with VD3, the bioavailability can be increased more and the effect of calcium supplement is improved. The calcium supplement effect of the compound amino acid chelate calcium is equivalent to the calcium supplement effect of calcium gluconate and higher than the calcium supplement effect of calcium carbonate, but the calcium retention rate of the compound amino acid chelate calcium is obviously higher than that of the calcium gluconate group and the calcium carbonate group.

Description

technical field [0001] The invention relates to a preparation method of a highly oil-resistant, heat-resistant and environment-friendly thermoplastic elastomer. Background technique [0002] At present, all kinds of calcium supplement health products on the market can be classified into three categories: one is inorganic calcium, also known as the first generation of calcium supplement products, such as: calcium carbonate, calcium phosphate and calcium oxide, or from mechanically processed animals Shell bones; the second type is organic acid calcium, that is, the second generation of calcium agents, such as: calcium gluconate, calcium lactate, calcium citrate, calcium acetate, etc.; the third type is organic calcium, which is the third generation of calcium agents, such as Amino acid chelated calcium, calcium L-threonate. The first and second types of calcium preparations have the following problems: they are generally difficult to dissolve, and some are highly alkaline and...
