Supercritical carbonic anhydride wall-breaking method for melissa powder

Abstract

The invention discloses a method using supercritical carbon dioxide to perform bee pollen broken-face. Bee pollen is put in an extraction plant of supercritical carbon dioxide, to react for a certain time in supercritical carbon dioxide liquid at the proper pressure and temperature, a vent valve is opened to rapidly empty carbon dioxide, so that a pollen cell expands acutely due to larger pressure difference of the inside and the outside, thereby cracking. The method has the advantages that the operation is simple and convenient, the cost is low, the whole process is performed below 50 DEG C,the broken-face time does not exceed 30 minutes, the influence of the product by thermotropy is reduced, so that the active ingredient is preserved completely, at the same time, bacillus can be killed, the unification of the broken-face and the sterilization processes is realized, the broken-face ratio of the pollen cell is high, but the percentage of damage is low, and the inclusion still existsin a cracked pollen wall under the dry condition, thereby favoring the preservation of the nutritious content.

Description

technical field [0001] The invention belongs to the technical field of natural product health care products and pharmacy, relates to a method for breaking bee pollen walls, and can be widely used in industries such as biopharmaceuticals and health food. Background technique [0002] Bee pollen is a mass formed by processing the pollen collected by bees from honey-pollen source plants. Bee pollen is very rich in nutrients and almost contains all nutrients. It is a high-quality source of nutrition, not only rich in protein, sugar Lipids, vitamins, organic acids, minerals, nucleic acids, as well as enzymes and other biologically active substances, are known as "miniature nutrient banks". Thousands of years ago, in ancient countries such as China and Greece, people began to eat pollen and use it as medicine. With the development of science and technology and the deepening of research, the health care functions of bee pollen have been gradually discovered, such as the prevention...

Problems solved by technology

Using this method to break the wall, the pollen needs to be soaked into a liquid before it can be processed, and the operation is complicated

[0005] (4) Fermentation and enzymatic wall-breaking method (patent application numbers 03115992.3, 87104508, 91106215.7, 95103910.5, 98104558.8, 02106399.0) is a widely used method, which uses the abundant microorganisms of pollen itself or the enzymes produced by inoculating microorganisms to make The content of pollen is degraded, and the osmotic pressure increases to break the pollen wall. This method takes a long time to break the wall, and it is easy to be contaminated by bacteria during the fermentation process, which will affect the quality.

This method is more complicated to operate, and the pollen content after breaking the wall is completely exposed to the external environment, which is prone to oxidative deterioration

[0009] The traditional wall-breaking methods have their own advantages, but the disadvantages are also obvious, or the treatment cycle is long, such as alternating cold and hot treatment methods and autolysis methods, which are inconvenient to use in production; or a large amount of heat is generated during the wall-breaking process, causing the pollen enzyme Loss of activity, such as various mechanical methods to break the wall; or high efficiency but expensive, such as enzymatic digestion, high-pressure homogeneous treatment and high-voltage electric field methods, which greatly increase product costs and cannot be popularized in production
