A method for preparing freeze-dried active placenta powder by water-soluble enzymatic hydrolysis

Abstract

The invention discloses a method for preparing freeze-dried active placenta powder through water solution enzymolysis. The method includes five technological steps including homogenizing, water solution, enzymolysis, freeze drying and ozone disinfection; water-soluble nutrient substances are extracted after placenta homogenizing, enzymatic products and the water-soluble substances are subjected to vacuum drying after stomach chymosin and chymotrypsin enzymolysis of insoluble substances, and finally, high-speed pulverization is achieved at a low temperature. The method has the advantages that low loss of placenta nutrient substances is guaranteed, separation and extraction efficiency is improved, the prepared active placenta powder is easy to digest and absorb, more than 98% of active substances can be maintained, and reliable scientific bases and technical measures are provided for producing health-care food by placentae.

Description

technical field

[0001] The invention belongs to a method for preparing bioactive placenta freeze-dried powder by combining water-soluble extraction and enzymatic hydrolysis. It belongs to the research and development field of health food. Background technique

[0002] Placenta, also known as "Ziheche", has a long history as a traditional Chinese medicine tonic in my country. Modern scientific research has found that placenta is rich in immune proteins, nutritional peptides, cytokines, terpenes and hormones, which can improve hematopoiesis. function, ovarian health care, promotion of lactation and beauty. Both fresh and dried placenta can be used as medicine. The "Compendium of Materia Medica" elaborates on its properties and medicinal effects: Ziheche "taste is sweet or salty", "nature is flat and warm", and it is home to the heart, lung and kidney meridians. , has the functions of nourishing blood, nourishing qi, replenishing essence, detoxifying, and nourishing blood. It ...

[0033] The human placenta active freeze-dried powder is obtained according to the following steps: take the human placenta that has been delivered naturally and passed the microbiological test, put the placenta into a plastic sample collection bag, seal it and immediately put it into -20°C for frozen storage; put the placenta from Take it out of the -20°C freezer for preliminary thawing, wash the surface with clean water until there is no blood stains and other sundries, and cut into about 3cm 3 small pieces, and then use a meat grinder to stir into a mince, called placental pulp, during which the temperature does not exceed 25°C;

[0034] Add 0.05-0.8% NaCl solution to the placenta slurry. If the placenta is 500g, then add 4000-6000mL of NaCl solution. In the probe-type 28KHz low-frequency ultrasonic processing device, the probe penetrates 3cm below the liquid surface of the solution, and the processing capacity is 250ml. Set the ultrasonic power to 250w, the ultrasonic time ...
