Abstract

The sheep placenta contains plentiful nutritive components and multikind of bio-active matter. The invented cryodried powder of sheep placenta is prepared up throught he process of washing, crushing and cryodrying. The cyrodried powder of sheep placenta processed by said invention contains 95% odd of the active component of sheep placenta. The said product can be preserved for a long period of time.

Description

Frozen dry powder of sheep placenta

The present invention is a kind of frozen dry powder of sheep placenta, belongs to nutrient and healthcare products, field of biological pharmacy.

Placenta caprae seu ovis claims the sheep afterbirth again, is the vital tissue structure that sheep Embryo Production stage of development fetus and parent carry out mass exchange.Placenta caprae seu ovis contains abundant nutrition and multiple bioactive substance.Placenta caprae seu ovis contains protein more than 80%, and its amino acid content is abundant, A wide selection of colours and designs, reasonable mixture ratio, and fat content about 10% wherein contains abundant phosphate ester, polysaccharide ester.Placenta caprae seu ovis also contains immunoglobulin, multiple antibody and interferon, and contains the various active polypeptide, the factor relevant with coagulation process, the auxin of promotion regeneration of erythrocytes, active substance relevant with the endocrine regulation functional disorder and various active enzyme.Therefore, Placenta caprae seu ovis can be used as medicine, health product, food, beverage, cosmetic material and additive.

On livestock products such as Inner Mongol ground, the resource of Placenta caprae seu ovis is very abundant, but because the problem (if adopt traditional processing method: dry, dry) of storage and transport causes its nutrition and bioactive substance destroyed.Therefore, the Placenta caprae seu ovis resource is not fully developed always.It is reported have the minority place to utilize Placenta caprae seu ovis to prepare hydrolyzed solution at present, be mainly used in the additive of cosmetics, oral liquid.But the complex manufacturing of hydrolyzed solution, yield poorly, and make that many morphological elements run off in the Placenta caprae seu ovis.The active ingredient that the Placenta Hominis hydrolyzed solution contains Placenta caprae seu ovis only 7%, the Placenta caprae seu ovis resource utilization is low.Placenta caprae seu ovis hydrolyzed solution antibacterial easily breeds in addition, should not grow its storage and transport.

In order effectively and fully to develop this resource of Placenta caprae seu ovis, spy of the present invention has proposed a kind of frozen dry powder of sheep placenta.

Frozen dry powder of sheep placenta of the present invention is cleaned Placenta caprae seu ovis, pulverize and is prepared from freeze dryer, and its technology is as follows:

1, after the Placenta caprae seu ovis that will meet quality standard was cleaned, system was worn into 80-200 order, water content also less than 90% granule;

2, pack into fast in the dried case of freeze dryer, the temperature of the dried case of freeze dryer is controlled at about-30 ℃;

3, in 1 hour, goods are frozen into below the eutectic point, about temperature-40 ℃;

4, insulation is after 1 hour, makes that the temperature of freeze dryer condensation tube reaches rapidly-50--55 ℃;

5, to the dried case evacuation of freeze dryer, make its vacuum reach 10P _a

6, goods distillation, temperature is at-40--26.5 ℃, and the time was at 8-14 hour;

7, product dried, temperature is at-26.5-35.9 ℃, and the time made water content less than 5% in 4-10 hour;

8, go out case packing, and sterilization.

In sublimation process, temperature is controlled at below the eutectic point, promptly-26.5 ℃; Vacuum is controlled at 20-30P in the mode of attemperation _a

Frozen dry powder of sheep placenta of the present invention is to utilize freeze dryer, with the Placenta caprae seu ovis quick freezing at low temperatures earlier after pulverizing, under suitable vacuum environment, make moisture content in the Placenta caprae seu ovis without the process of water from ice, aquation gas then, directly distillation is overflowed for aqueous vapor, Placenta caprae seu ovis is in low temperature state all the time before drying, therefore use Freeze Drying Technique than other seasoning, as dry, heat, evaporation, oven dry, spray drying and film drying etc. are superior, this dry powder has following advantage:

1, product volume is constant substantially, has kept the structure of original material, has avoided solute to concentrate and makes goods rotten.

2, short texture after the lyophilization adds very easily dissolving behind the water, recovers original character immediately.

3, Placenta caprae seu ovis carries out at low temperatures, and the temperature of the later stage of drying also is controlled at below 36 ℃, and is therefore suitable especially for the kept dry of some heat labile protein and lived microorganism.

4, the dried matter water content is less than 5%, and the long preservation that helps the Placenta caprae seu ovis powder is convenient to storage and transportation.

5, product dried is carried out under vacuum condition, therefore is difficult for oxidation, owing to be sublimation drying, does not therefore produce foam.

Embodiment:

With 2400 the gram the Placenta caprae seu ovis quick-thawings, clean, dry, rub.Wear into the 80-200 order with colloid mill and super-low temperature pulverizator, moisture slip below 95%.When the dried oven temperature, degree of freeze dryer be chilled in advance-during 20--35 ℃, slip is put into dried case, products temperature is reached below the eutectic point ,-35--45 ℃, be incubated about 1 hour.When freeze dryer condensation tube temperature reach-during 45--55 ℃, the beginning evacuation, dried case vacuum is less than 10P _aThe time to the heating of dried case goods, make the moisture content of the state that freezes in its goods be sublimed into gas, condense into frost through condensation tube again.At sublimation stage, the vacuum of dried case is at 30-20P _a, otherwise will adjust in the mode of heating.Then dried oven temperature, degree is controlled at-carried out dry 4-10 hour between 26.5-36 ℃, the water content that makes goods goes out case packing less than 5%, after the co-60 radiation sterilization.

Claims

1, the present invention is a kind of frozen dry powder of sheep placenta, belongs to nutrient and healthcare products, field of biological pharmacy, and it is cleaned Placenta caprae seu ovis, pulverize and be prepared from freeze dryer, and its feature is as follows:
