However, there are four disadvantages in this method: first, the purification conditions are very high, requiring a temperature as high as 1400-1900 °C; second, the cycle is long, and each step takes about 10 hours; 400~600℃, 4. Compared with fresh animal bone resources, the source of raw materials is not easy to obtain, and the source is not wide enough and sufficient

Embodiment 1

[0026] The method for calcium ionization in the bovine stick bone of embodiment 1

[0027] Such as figure 1 Shown, the calcium ionization in the bovine stick bone of the present embodiment is made by following method:

[0028] 1) Preparation of bone meal:

[0029] Grind the fresh beef stick bone to obtain the beef stick bone paste with a particle size of 80 mesh; then use chemical methods to degrease, mix the bone paste with a concentration of 0.4% NaOH solution, and degrease under stirring at room temperature, the stirring speed is 60r / min , time of 6 hours, to obtain the defatted bone paste, and then wash the defatted bone paste with clear water for several times, filter until the bone paste is neutral, and drain the water; dry with hot air and ultrafinely pulverize to obtain the bone powder with a particle size of 200 mesh. .

[0030] 2) Determination of extraction solvent:

[0031] Two kinds of extraction solvents, citric acid and lactic acid, were used respectively to...

Embodiment 2

[0057] The method for calcium ionization in the pig stick bone of embodiment 2

[0058] Calcium ionization in the pig rod bone of the present embodiment is made by following method:

[0059] The preparation of bone powder includes: crushing fresh pig bones to obtain bone paste with a particle size of 120 meshes; degreasing by chemical methods, mixing evenly with 0.8% NaOH solution and stirring at room temperature, and stirring at a speed of 90r / min for 10 hours to obtain the defatted bone paste, which was washed with clean water several times and filtered until the bone paste was neutral.

[0060] Lactic acid, citric acid, and a mixed acid of lactic acid and citric acid (lactic acid: citric acid = 1:5) with an acid concentration of 5% were used as extractants, and the concentration of bone paste (calculated as solids) in the acid solution was 3%. , the acid-lyzed bone meal was treated under the following conditions: 1) standing at room temperature for 4 hours; 2) stirring in...

Embodiment 3

[0065] The method for calcium ionization in the pig scapula of embodiment 3

[0066] Calcium ionization in the pig scapula of the present embodiment is made by the following method:

[0067] Prepare bone powder, including: crushing fresh pig scapula to obtain pig scapula bone paste with a particle size of 100 mesh; then degreasing by chemical method, mixing evenly with 0.6% NaOH solution and bone paste, degreasing under stirring at room temperature, stirring speed 100r / min for 5 hours to obtain degreased bone paste, which was washed with clean water several times and filtered until the bone paste was neutral, then drained; dried with hot air and ultrafinely crushed to obtain pigs with a particle size of 200 mesh Shoulder bone meal.

[0068] Lactic acid, citric acid, and a mixed acid of lactic acid and citric acid (lactic acid: citric acid = 2: 7) with an acid concentration of 7% were used as extractants, and the concentration of bone paste (calculated as solids) in the acid s...

Abstract

The invention relates to an ionized calcium exacted from animal bones and preparation method thereof. The preparation method comprises: 1) grinding the animal bones, degreasing and drying to obtain bone powder; 2) extracting the bone powder with concentration of 1%-7% by acid fluid with concentration of 1%-8%; 3) centrifuging to obtain supernatant; and 4) drying the supernatant to obtain ionized calcium dry powder. The invention has a wide source in raw materials, utilizes existing waste resources, achieves the advantages of high calcium leaching rate, short processing time and almost no change in nutrition compositions between the samples pre and after processed, low production cost, high production efficiency and good economic benefit; and the product is suitable for being applied in food, functional food and medicine field.

Description

technical field [0001] The invention relates to a method for extracting ionized calcium, in particular to a method for extracting ionized calcium from the bones of livestock. Background technique [0002] Calcium is the regulator of human life activities and the source of life for the human body. Eating bone foods and absorbing calcium from various bones is the most ideal way to supplement calcium. my country can produce about 20 million tons of livestock and poultry bones every year. Except ribs and cavity bones can be directly used for diet and have a large demand, general bones are often discarded, or processed into bone meal and added to feed, causing great waste and pollution. Making full use of bone resources and vigorously exploiting the nutrients in animal bones has become an urgent problem to be solved in the food industry. Therefore, fresh animal bone is a veritable nutritional treasure house with high development and utilization value. [0003] Domestically, th...
