Problems solved by technology

The acid hydrolysis method uses acid to dismantle the salt bond and ester bond of the protein in the collagen fiber, so that the hydroxyapatite combined with the collagen fiber is exposed; then the acid is used to act on the hydroxyapatite to convert bone calcium into soluble calcium. Most of the mineral elements in the bone are retained, and the extract is used as an additive for liquid drinks or powdered granules. However, there is no effective research on the sediment after acid treatment, and most of them are discarded or directly used as feed additives, with low added value. , the utilization rate is not high, and the waste is serious

example 1

[0013] Step 1: In 3 liters of mixed solution, add compound enzyme according to 0.3% of the weight of the sediment, and enzymolyze for 2.5 hours under stirring conditions at a temperature of 45°C and pH8; the weight ratio of papain and lipase in the compound enzyme is 1︰0.8;

[0014] Step 2: After the enzymolysis is completed, heat up the mixed solution to inactivate, the inactivation temperature is 80°C, and the time is 20 minutes; the solid-liquid separation is carried out by static method;

[0015] Step 3: The obtained liquid is naturally dried and crushed to obtain 302 g of bovine bone beneficial ingredient powder extract, which can be used as an additive for liquid drinks or powder granules.

example 2

[0017] In 9 liters of mixed solution, add compound enzyme by 0.4% of the weight of the precipitate, and enzymatically hydrolyze for 3 hours under stirring conditions at a temperature of 40°C and pH7.6; the weight ratio of papain and lipase in the compound enzyme is 1 : 1.2;

[0018] Step 2: After the enzymatic hydrolysis is completed, heat up the mixed solution to inactivate, the inactivation temperature is 90°C, and the time is 18 minutes; the solid-liquid separation is carried out by static method;

[0019] Step 3: Vacuum freeze-dry the obtained liquid and then pulverize it to obtain 898 g of bovine bone beneficial ingredient powder extract, which can be used as an additive for liquid drinks or powder granules.

example 3

[0021] In the mixed solution of 19 liters, add compound enzyme by 0.6% of sediment weight, under the stirring condition of temperature 42 ℃, PH7.8, enzymolysis 3 hours; The weight ratio of papain and lipase in compound enzyme is 1 ︰1;

[0022] Step 2: After the enzymatic hydrolysis is completed, heat up the mixed solution to inactivate, the inactivation temperature is 98°C, and the time is 16 minutes; the solid-liquid separation is carried out by static method;

[0023] Step 3: Spray-dry the obtained liquid to obtain 1873g of bovine bone beneficial ingredient powder extract, which can be used as an additive for liquid drinks or powdered granules.

Abstract

The invention provides an extraction method of beneficial components in sediment obtained by acid treatment on cattle bones. The extraction method comprises the following steps: after treating cattlebone meal by acid extraction, washing the obtained sediment and carrying out solid-liquid separation; adding water into the sediment obtained by the solid-liquid separation and uniformly stirring; then adding complex enzymes (including papain and lipase) and carrying out enzymolysis, enzyme inactivation and drying to obtain cattle bone beneficial component extract which is easily dissolved into water and contains various beneficial components, wherein the beneficial components in the extract are organic nutrient substances including low molecular weight polypeptide, amino acid and the like, and the fat content is low; the calcium content is 16 percent or more and the total phosphorus content is 8 percent or more. By adopting the extraction method provided by the invention, total utilization of the cattle bone meal is realized and the additional value is high; in a production process, no waste liquid and no waste gas are discharged; the obtained product is easily dissolved into the water, has no undesirable odor and is easily absorbed by human bodies, so that the product is applicable to a calcium-supplementing additive of various beverages, various granules and foods. The product has low fat content, and the safety and health of consumers with cardiovascular diseases are facilitated.

Description

technical field [0001] The invention belongs to the technical field of chemical extraction, and in particular relates to a method for extracting beneficial components in sediments after bovine bones are treated with acid. Background technique [0002] According to analysis, animal bones contain a variety of substances that are nutritious, nourishing and health-care to the human body, and have the health-care effects of adding bone marrow, increasing blood, slowing down aging, and prolonging life. Animal bones are processed and added or fortified into food, which is especially beneficial to the elderly, menopausal women and children. In China, bone is mainly used in bone oil, bone meal, bone gelatin, etc. The characteristic of this utilization method is that the bone is not further processed, because the resulting product tastes bad and has low added value. And because of the special bone structure, the nutrients contained in it are not easy to be digested and absorbed by th...
