Embodiment Construction

[0028] The specific implementation of the present invention will be further explained through the following examples, but it does not mean that the protection scope of the present invention is limited to the scope described in the examples.

[0029] Embodiment Prepare pig placenta freeze-dried powder with the method of the present invention

[0030] The preparation method is as follows:

[0031] a. Take fresh pig placenta, freeze it at -40°C, thaw it completely at 4°C during preparation, and wash off the blood on the surface;

[0032] b. Use a high-speed tissue grinder to pulverize the washed pig placenta for 30 seconds, pour it into a freeze-drying tray, spread the placenta to a thickness of 5 cm, and perform the first freeze-drying: pre-freeze at -45°C for 2 hours, The sublimation temperature is -38°C for 15 hours, 10°C for 4 hours, and 30°C for 4 hours;

[0033] c. After step b is completed, turn over the pig placenta in the freeze-drying tray, and perform the second free...

Abstract

The invention belongs to the technical field of food processing and particularly relates to a purpose of pig placenta freeze-dried powder in resisting oxidation. Based on the problem that the pig placenta freeze-dried powder is not applied to skin oxidation resistance in the prior art, the invention provides a purpose of applying the pig placenta freeze-dried powder to prepare a skin care product resisting skin aging. A preparation method of the pig placenta freeze-dried powder comprises: (a) taking a pig placenta frozen at (-50)-(-30) DEG C, and unfreezing at 4-10 DEG C; (b) crushing the pig placenta with a high-speed tissue mashing machine, pouring into a freeze drying tray, and performing first time of freeze drying; (c) after the step (b) is completed, turning over the pig placenta entirely in the freeze drying tray, and performing second time of freeze drying; (d) putting the pig placenta dried in the step (c) into an aluminum foil bag, vacuumizing, and storing at 4 DEG C for later use. The method is easy to operate and can maintain the nutritional ingredients and antioxidant active ingredients in the pig placenta to the greatest extent; the prepared pig placenta freeze-dried powder has an oxidation resisting function and has important economic benefits.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to the anti-oxidation application of freeze-dried porcine placenta powder. Background technique [0002] A notable feature of skin aging is the gradual thinning of the skin epidermis, which is caused by factors such as the reduction of cell viability on the one hand and the excessive accumulation of free radicals in the body on the other hand. Free radicals are molecules or atoms with one or several unpaired electrons with high oxidation activity, and have strong oxidation activity. Although an appropriate amount of free radicals has positive effects on cell division, growth, anti-inflammatory and detoxification, excess free radicals can induce inflammation, immune disorders, malignant tumors and other diseases, which are the main killers of skin aging. [0003] In Chinese medicine, human placenta is called Ziheche, and its medicinal effect is clearly recorded in the "Compe...
