Method for preparing fresh pilose antler active cell extract freeze-dried powder

Abstract

The invention discloses a method for preparing freeze-dried powder of an active cell extract of fresh pilose antler. The preparation method comprises the following steps: fresh and frozen pilose antler is taken out, is sliced, is ground, is added with ethanol, is evenly stirred, is subjected to breaking treatment through an ultrasonic breaking instrument, and is centrifugated to obtain two parts of supernatant liquid and sediment; the part of the supernatant liqid is decompressed, condensed, frozen and dried through a freezedryer to prepare dry powder; and the sediment part is added with the ethanol, is heated and is subjected to ultrasonic breaking treatment and centrifugation. Through the three steps, a finished product can be obtained. The method uses the fresh pilose antler as a raw material, has stage extraction of low temperature and high temperature, ensures that enzyme and other biological active substances are not deactivated in the extraction process and simultaneously ensures the full extraction of other effective compositions. Through detection, the prepared product through the method has stable and high activity of SOD, which shows that the active substances in the cell are well stored and the effective compositions have high contents.

Description

technical field [0001] The invention relates to a preparation method of freeze-dried powder of cell extract, in particular to a preparation method of freeze-dried powder of active cell extract of fresh deer antler. Background technique [0002] Deer antler is a precious Chinese medicinal material, and at the same time, it is widely used as a nutritional tonic in the industries of health care products, food and cosmetics. The known nutrients in deer antler mainly include polypeptides, nucleotides, fatty acids, and some active enzymes and hormones. At present, the traditional method of processing velvet antler at home and abroad is to boil fresh velvet in boiling water after harvesting, then bake in an infrared oven at 70°C, and then air-dry. In this process, more blood loss. At the same time, due to the effect of high temperature, the active ingredients in velvet antler lose a lot. In the processed antler, the activities of superoxide dismutase (SOD) and alkaline phosphata...

At the same time, due to the effect of high temperature, the active ingredients in deer antler lose a lot

In the processed velvet, the activities of superoxide dismutase (SOD) and alkaline phosphatase (AKP) decreased significantly.

In addition, according to the traditional extraction process, velvet slices are soaked in wine or extracted with organic solvents. Due to the microporous structure of velvet, it takes a long time for extraction, and at the same time, it will also cause pollution due to residual organic solvents.
