Problems solved by technology

[0003] In addition to chemically synthesized calcium supplements, at present, natural calcium resources such as oyster shells are used as raw materials at home and abroad to produce calcium carbonate, calcium lactate, etc., mainly by calcination, and some fish bones are directly crushed into bone calcium powder. The body's absorption rate of these calcium is not very high

Embodiment 1

[0024] 1. Tilapia processing leftovers - fish head, fish rafts and water are mashed according to the ratio of 1:1, put in a container, add 2% 1398 protease, stir well, heat to the center temperature of 45°C, Decompose for 3 hours, take out the fish bones, wash them with hot water, dry them, and crush them;

[0025] 2. Prepare 12% mixed solution of citric acid and malic acid in an acid-resistant container, the ratio of citric acid and malic acid is 3:2, and the ratio of bone meal and mixed acid solution is 1:3, put the tilapia bone meal into In the acid solution, soak for 60 hours without stirring regularly;

[0026] 3. Centrifuge after acid treatment, take the supernatant, slowly add calcium hydroxide, stir while adding, adjust the pH to neutral; then dry to get the finished product.

Embodiment 2

[0028] 1. Tilapia processing leftovers - fish head, fish fillet and water are mashed according to the ratio of 1:1, put in a container, add 1% 1398 protease, stir evenly, heat to the center temperature of 50°C, enzyme Decompose for 2 hours, take out the fish bones, wash them with hot water, dry them, and crush them.

[0029] 2. Prepare a 10% mixed solution of citric acid and malic acid in an acid-proof container, the ratio of citric acid and malic acid is 3:2, put the tilapia bone meal in the ratio of 1:4 by bone meal and mixed acid solution In the acid solution, soak for 70 hours, pay attention to stirring occasionally.

[0030] 3. Centrifuge after acid treatment, take the supernatant, slowly add calcium hydroxide, stir while adding, adjust the pH to neutral; then dry to get the finished product.

Embodiment 3

Abstract

The active carbon producing process with tilapid bone includes the first enzyme processing, cleaning, stoving and crushing to obtain fish bone powder; the subsequent acid processing and activating process of the fish bone powder; and final stoving to obtain product. The said process changes the waste into high value matter and produces high absorption calcium CMC via extracting with mixed citric acid and malic acid. The bioavailability test shows that the active calcium has biological absorption rate as high as 60 %. In addition, the technological process is simple, low in production cost and stable in product quality.

Description

technical field [0001] The invention relates to a process for deep processing of freshwater fish, in particular to a process for producing active calcium from tilapia bones. Background technique [0002] The physiological metabolism of calcium in the human body plays an extremely important role in health. It is the fifth important nutrient element after C, H, O, and N. It is the most important cation in the human body. Calcium deficiency in the human body will cause diseases such as osteoporosis. [0003] In addition to chemically synthesized calcium supplement products, at present, natural calcium resources such as oyster shells are used as raw materials at home and abroad to produce calcium carbonate, calcium lactate, etc., mainly by calcination, and some fish bones are directly crushed into bone calcium powder. The body's absorption rate of these calcium is not very high. With the continuous development of the tilapia processing industry, fish bones account for the majo...
