Problems solved by technology

However, the form of amniotic fluid itself and its fishy smell greatly limit its edibility and market acceptability, which makes amniotic fluid not yet applied and developed in food health care.
And amniotic fluid contains a lot of water, which is not conducive to food processing, preservation and consumption. Ordinary high-temperature evaporation can easily cause thermal decomposition of amniotic fluid components and inactivation of active substances.

Embodiment 1

[0025] The present embodiment provides a method for preparing avian amniotic fluid protein powder. The birds include chickens, ducks, geese, quails and other bird species, and the specific steps include:

[0026] (1) Fractional purification of avian amniotic fluid

[0027] After the avian amniotic fluid was extracted with a syringe, centrifuge at 10,000 rpm / min for 15 min at 4 °C, and the supernatant was taken for use;

[0028] The supernatant is further separated and purified through a filter membrane with a pore size of 200KDa and a molecular weight, and the filtrate is used for later use. The separation and purification in this step can enrich and concentrate the macromolecular active protein in the amniotic fluid.

[0029] The filtrate is further separated and purified through a filter membrane with a pore size of 5KDa and a molecular weight, and the retentate is taken for later use. The separation and purification of this step can remove water, small molecular salts, mine...

Embodiment 2

[0037] The present embodiment provides a preparation method of avian amniotic fluid protein powder, and the specific steps include:

[0038] (1) Fractional purification of avian amniotic fluid

[0039] After extracting the amniotic fluid of birds with a syringe, centrifuge at 11000rpm / min at 4°C for 10min, and take the supernatant for use;

[0040] The supernatant is further separated and purified through a filter membrane with a pore size of 200KDa and a molecular weight, and the filtrate is used for later use. The separation and purification in this step can enrich and concentrate the macromolecular active protein in the amniotic fluid.

[0041] The filtrate is further separated and purified through a filter membrane with a pore size of 5KDa and a molecular weight, and the retentate is taken for later use. The separation and purification of this step can remove water, small molecular salts, minerals and lipids in the amniotic fluid.

Embodiment 3

[0049] The present embodiment provides a preparation method of avian amniotic fluid protein powder, and the specific steps include:

[0050] (1) Fractional purification of avian amniotic fluid

[0051] After avian amniotic fluid was extracted with a syringe, centrifuge at 12,000 rpm / min for 5 min at 4°C, and the supernatant was taken for later use;

[0052]The supernatant is further separated and purified through a filter membrane with a pore size of 200KDa and a molecular weight, and the filtrate is used for later use. The separation and purification in this step can enrich and concentrate the macromolecular active protein in the amniotic fluid.

[0053] The filtrate is further separated and purified through a filter membrane with a pore size of 5KDa and a molecular weight, and the retentate is taken for later use. The separation and purification of this step can remove water, small molecular salts, minerals and lipids in the amniotic fluid.

Abstract

The invention relates to amniotic fluid protein powder, a preparation method thereof and application of the amniotic fluid protein powder and belongs to the technical field of food processing. The amniotic fluid protein powder comprises amniotic fluid, adjuvants, flavorings and embedding media, is high in nutritive value and easy to dissolve and can be used for strengthening organism immunity. According to the amniotic fluid protein powder, the preparation method thereof and the application of the amniotic fluid protein powder, through cooperative action of a variety of processes such as ultrafiltration, microcapsule embedding and freeze drying, offensive-smell matters can be removed from the amniotic fluid; a full-bodied fragrance is generated by using the flavorings with natural fragrances, so that the problem in offensive-smell removing of the amniotic fluid is solved thoroughly; by using a segmented type purification technology, important nutrients in the amniotic fluid are thoroughly reserved and concentrated; and by using a microcapsule embedding technology, losing of activity of active proteins during transportation and storage is avoided, the shelf life of the product is prolonged, and application of the amniotic fluid in food industry is extended.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to an amniotic fluid protein powder and a preparation method and application thereof. Background technique [0002] Amniotic fluid refers to the fluid located in the amniotic cavity during embryonic development. It is an indispensable and important component for maintaining embryonic life during embryonic development. Many life metabolic activities need to be carried out through amniotic fluid. More and more evidences show that amniotic fluid is rich in Nutrition. [0003] From the 13th day of hatching, the embryo gradually absorbs the amniotic fluid. When the embryo matures (about 18d), the amniotic fluid is almost completely absorbed. During this period, the embryo can swallow the amniotic fluid to absorb the active factors and antibacterial substances before synthesis. body, amino acids, glucose and other soluble nutrients to support and promote its own growth and develo...
