This invention provides a method for producing odor-reduced placenta extract that virtually eliminates the characteristic odor contained in raw placenta that has been excreted. [Solution] A method for producing odorless placenta extract comprising an enzymatic decomposition step S02 in which an enzyme is added to the placenta that has been expelled late and enzymatic decomposition is performed, and a lactic acid bacteria decomposition step S03 in which lactobacilli are added to the placenta obtained in the enzymatic decomposition step S02 and lactic acid bacteria decomposition is performed.

The application discloses a biomass quantum dot enabled double-effect grading repair whitening and anti-aging mask formula and a preparation method thereof. The formula comprises a cleaning and anti-irritation mask and a functional mask. The cleaning and anti-irritation mask and the functional mask both comprise the following raw materials: water, glycerol, propylene glycol, butylene glycol, 1,2-hexanediol, 1,2-pentanediol, tripartite grass leaf / root extract, dandelion leaf extract, p-hydroxyacetophenone, radix stephaniae tetrandrae extract, ethylhexylglycerin, polysorbate-80, palmitoyl pentapeptide-4, ethanol, umbilical cord extract, phenoxyethanol, hydrolyzed placenta extract, palmitoyl tripeptide-1, sodium hyaluronate, hydroxyethyl cellulose, disodium hydrogen phosphate, sodium dihydrogen phosphate, polysorbate-60, sodium polyglutamate, tremella fuciformis fruiting body extract and biomass quantum dots. The biomass quantum dots are added in an amount of 0.5-1.2 parts by weight in the cleaning and anti-irritation mask and in an amount of 1.0-1.7 parts by weight in the functional mask.

The invention discloses an application of a sheep placenta extract in preparation of a medicine for improving polycystic ovarian syndrome, and relates to the technical field of biological medicine, the medicine is used for improving endocrine disorder and abnormal inflammation caused by the polycystic ovarian syndrome, and particularly for reducing the plasma androgen level and increasing the plasma estrogen level and the plasma progestational hormone level; the level of an inflammatory factor TNF-alpha is reduced, and the level of an inflammatory factor IL-10 is increased. The sheep placenta extract can improve ovarian polycystic lesions caused by polycystic ovarian syndrome (PCOS) in a targeted manner, and experiments show that after intervention of the sheep placenta extract, the number of macroscopic cystic follicles in rat ovary is reduced, the weight of the ovary with abnormal weight gain is remarkably reduced, the cystic follicle ratio in ovarian histopathology detection is greatly reduced, and the sheep placenta extract has a good application prospect. The ratio of the number of the corpus luteum is closer to normal, and the pathological injury of the polycystic ovarian syndrome is repaired from the organ level.

The invention relates to the technical field of freeze-drying type anti-aging cosmetics, and discloses a composition for a double-dosage form freeze-drying essence, the double-dosage form freeze-drying essence and a preparation method and application of the double-dosage form freeze-drying essence. The composition contains a freeze-drying preparation mixture and an activation solvent mixture in a mass ratio of 1: (2-3), the freeze-drying preparation mixture contains a first main agent and a first auxiliary agent, and the first main agent contains 3-o-ethyl ascorbic acid, an animal umbilical cord extract, sodium hyaluronate, oligopeptide-1 and a hydrolyzed sheep placenta extract; the activating solvent mixture contains a second main agent and a second auxiliary agent, and the second main agent contains schizophyllacin and decapeptide-4. Through double-dosage-form isolation protection, a stepped freeze-drying process and facial three-dimensional network construction, the double-dosage-form freeze-drying essence provided by the invention has higher active component content, more stable performance and longer facial retention time.

The application belongs to the technical field of bioactive extract preparation, and discloses a preparation method of high-purity animal placenta extract with controlled enzymolysis and molecular weight, which comprises sequentially connected raw material low-temperature homogenization treatment, gradient temperature-controlled enzymolysis, transient mild enzyme inactivation, double-mode membrane fractionation for molecular weight control, low-temperature concentration, activity locking and sterile filtration. The application adopts a complex protease system matched with a segmented gradient temperature-controlled enzymolysis process, and combines a neutral mild pH environment of 6.3-7.8 to accurately control the enzymolysis site and degradation degree, completely solve the technical problems of uncontrollable enzymolysis, excessive degradation or insufficient degradation and excessive large molecule residue caused by single enzymolysis and extensive enzymolysis in the traditional process, and greatly improve the uniformity of the enzymolysis process, thereby guaranteeing the stable quality of the extract from the source and being beneficial to actual application and operation.
