Problems solved by technology

Although there are related records on the utilization of pig bones in the prior art, such as CN102579494A, CN110506921A, etc., they only extract some elements in pig bones, and the preparation method requires the participation of reagents such as enzymes or acids, and the preparation process is complicated.
In view of the fact that pig bones have not been effectively utilized, and deep processing of pig bones is less than 5%, resulting in a huge waste of resources, it is imminent to rationally use pig bone resources, develop new pig bone processing technology, and promote the development of the food industry

preparation example Construction

[0018] The invention provides a kind of preparation method of concentrated porcine bone extract, comprises the following steps:

[0019] The pig bone raw material is subjected to subcritical water hydrolysis, and the hydrolyzed solution is filtered and concentrated to obtain concentrated porcine bone; the subcritical water hydrolysis is carried out in an oxygen-free environment.

[0020] In the present invention, the pig bone raw material is preferably pig leg bone, skull or scapula; the pig bone raw material is preferably crushed into bone dregs before subcritical water treatment; the diameter of the bony dregs is preferably 1-3 cm. In the present invention, the pork bone raw material is preferably soaked and washed before crushing, and the accompanying meat is removed to remove excess blood stains and floating foam, thereby reducing the protein and fat contained in the meat, and ensuring that the color of the bone broth is pure and without burnt Muddy. In the present invent...

Embodiment 1

[0027] (1) Pretreatment and crushing

[0028] Wash 250g of fresh pork leg bones, remove any attached meat as much as possible, then use a bone crusher to crush the pork leg bones into bone residues with a diameter of 1 cm, rinse and soak them in clean water until there are no blood stains and foam in the bone residues .

[0029] (2) Subcritical water treatment

[0030] Put the pig leg bone slag into a subcritical device reaction tank, add 500g of pure water and mix well, replace the air in the reaction tank with nitrogen, keep the pressure at 0.5Mpa, and the reaction temperature at 110°C for 1 hour , to obtain pork leg bone hydrolyzate.

[0031] (3) filter

[0032] The obtained pig leg bone hydrolyzate is filtered with a plate and frame ultrafiltration machine with a filter membrane pore size of 0.4 μm to remove unhydrolyzed pig bone residues to obtain pig bone broth.

[0033] (4) concentrated

[0034] Use a rotary evaporator to concentrate the original pork bone broth at...

[0038] (2) Subcritical water treatment

[0039] Put the pig leg bone slag into a subcritical device reaction tank, add 750g of pure water and mix well, replace the air in the reaction tank with nitrogen, keep the pressure at 1Mpa, and the reaction temperature at 120°C for 1 hour. Obtain pork leg bone hydrolyzate.

[0040] (3) filter

[0041] The obtained pig leg bone hydrolyzate is filtered with a plate and frame ultrafiltration machine with a filter membrane pore size of 0.5 μm to remove unhydrolyzed pig bone residues to obtain pig bone broth.

[0042] (4) concentrated

[0043] Use a rotary evaporator to concentrate the original pork bone broth at a tem...

Abstract

The invention relates to the field of concentrated ossein, and provides a preparation method of concentrated pig ossein and application thereof. The method comprises the following steps: carrying out subcritical water hydrolysis on pig bone raw materials, filtering hydrolysate, concentrating to obtain the concentrated pig ossein, and the subcritical water hydrolysis is carried out in an oxygen-free environment. The preparation method is high in efficiency, free of pollution and mild in condition, the decomposition rate of the pig bone raw material is as high as 70%, the prepared concentrated pig ossein is good in color, pure in flavor, rich in trace element and rich in protein content, and particularly the calcium content is 30-40 times that of common commercially available bone soup.

Description

technical field [0001] The invention relates to the field of concentrated porcine bone, in particular to a preparation method and application of concentrated porcine bone. Background technique [0002] Subcritical water, also known as superheated water, high-pressure hot water or hot liquid water, refers to heating water to a high temperature above 100°C and below the critical temperature of 374°C under a certain pressure, and the water remains in a liquid state. In the subcritical state, the hydrogen bond, ion hydration, ion association, cluster structure, etc. of the fluid microstructure have changed, so the physical and chemical characteristics of subcritical water are quite different from those of water at normal temperature and pressure. The polarity of water at normal temperature and pressure is strong, and in the subcritical state, as the temperature rises, the hydrogen bonds of subcritical water are opened or weakened, so as to achieve the purpose of extraction. In ...
