Problems solved by technology

The production operation of this method is complex and the cycle is long, in which the soaking in hydrochloric acid takes 3 to 20 days, and the soaking in soda ash is then neutralized, which easily destroys the amino acids in the bone
[0008] In short, the current processing methods of bone products are complicated in operation, high in production cost, and polluting in emissions. The resulting products have poor water solubility, poor taste, and are difficult to be absorbed by the human body.

example 1

[0022] Step 1: Add 100 g of bone meal to 1 L of 3.2% dilute hydrochloric acid solution, stir at room temperature for 1.5 h, then let stand for 2 h until the mixture is separated to obtain a lower mixed liquid and an upper suspended liquid;

[0023] Step 2: Centrifuge the lower mixed solution to separate the solid from the liquid, mix the obtained supernatant with the above-mentioned upper suspension, wash the precipitate twice with water and separate the solid from the liquid; dry the washed precipitate and pulverize it as Feed additives, recovering the separated washing water for the preparation of dilute hydrochloric acid solution;

[0024] Step 3: Dry the upper layer suspension in Step 1 naturally under ventilated conditions to obtain 98.4 g of hydrous colloidal extract, which can be used as an additive in the production of liquid drinks or powdered granules.

[0025] For example: Dissolve 3g of colloidal extract in 90mL of 80°C hot water to obtain a colorless, odorless aqu...

example 2

[0027] Step 1: Add 500 g of bone meal to 5 L of 3.2% dilute hydrochloric acid solution, stir at room temperature for 2 hours, and then let stand for 2.5 hours until the mixture is separated into layers to obtain a lower mixture and an upper suspension;

[0028] Step 2: Wash the lower mixed solution with water for 3 times and separate the solid from the liquid; process the washed sediment and washing water according to the above-mentioned Example 1;

[0029] Step 3: The upper layer suspension in Step 1 was naturally dried under ventilated conditions to obtain 481.4 g of water-containing colloidal extract, which can be used as an additive in the production of liquid drinks or powdered granules.

[0030] Such as: dissolving 6g of colloidal extract in 200mL of hot water at 76°C to obtain a colorless, odorless aqueous solution containing calcium extract (with a little white precipitate), pH 2, and calcium content 15.2%. In addition, add 2 g of citric acid to 6 g of colloidal extrac...

example 3

[0032] Step 1: Add 1000g of bone meal to 10L of 3.2% dilute hydrochloric acid solution, stir at room temperature for 2.5 hours, then let stand for 3 hours until the mixed solution is separated to obtain the lower mixed solution and the upper suspended solution;

[0033] Step 2: wash the lower mixed solution with water for 3 times and separate the solid from the liquid; process the washed sediment and washing water according to Example 1;

[0034] Step 3: Vacuum freeze-dry the upper layer suspension obtained in Step 1 and pulverize to obtain 705.3 g of white, odorless freeze-dried powder containing calcium extract.

[0035] Or the upper layer suspension obtained in step 1 is spray-dried to obtain 702.6 g of white, odorless calcium-containing extract dry powder.

[0036] After testing, the obtained calcium-containing extract has a calcium content of 14.7%, a total phosphorus content of 7.35%, and is rich in other minerals and nutritive organic matter. It is suitable for additive...

Abstract

The invention relates to a preparation method for a yak bone calcium-containing extract. The preparation method for the yak bone calcium-containing extract comprises the following steps: taking bone powder with meshes of 120 as a raw material; dissolving the bone powder by using diluted hydrochloric acid; carrying out solid-liquid separation after standing; and drying to obtain the yak bone calcium-containing extract. Through test detection, the yield of the bone powder is 70% or above, and the remaining 30% of residues can be used as an additive for feed of poultry and livestock; and in the extract, the content of calcium is 14.7%, the content of total phosphorus is 7.35%, and the extract is rich in other mineral substances and nutritive organic matters. The preparation method has the advantages of simple production process, convenience in operation, short production period and low production cost (which is only 1/3 of like products in the market at present). Strong acid and strong base are not used, an extracting solution is recycled, waste liquid or waste gas is not discharged in a production process, and corrosion to production equipment and pollution to the environment are minimized; and the obtained product is completely dissolved in water, does not have odor, is easily absorbed by human bodies, and is suitable for various beverages, various electuaries and calcium supplementing additives of food.

Description

technical field [0001] The invention belongs to the technical field of chemical extraction, and in particular relates to a preparation method of a yak bone calcium-containing extract. Background technique [0002] Western my country is rich in yak resources. According to the Tibetan medicine classics "Jingzhu Materia Medica", yak bones increase heat, dispel cold, invigorate stomach fire, and treat stomach cold. Yak bone is rich in calcium, zinc, phosphorus, magnesium, iron, copper, manganese, nickel and more than ten kinds of elements needed by the human body. Traditional Tibetan medicine, Mongolian medicine and Chinese medicine all use the unique yak bone of the Qinghai-Tibet Plateau as a precious medicinal material, so yak bone is a food material with extremely high nutritional value. However, due to the special bone structure of yak bone, the nutrients contained in it are not easy to be digested and absorbed by the human body, and must be specially processed to be absorb...
