Abstract
The present invention belongs to the technical field of preparing cordyceps mycelium powder by a manual fermentation method and especially relates to a preparation method of the cordyceps mycelium powder by microwave drying. The method is that cordyceps strain separated from natural cordyceps, which is cultured for a plurality of times to obtain the final bacterial liquid which is filtered to obtain a filter cake after being removed the filtrate. The present invention is characterized in that the filter cake is dried by microwave to remove water, the condition of microwave drying is 2450Hz plus or minus 500Hz, and the drying time is 7 to 20 minutes. The method has a series of advantages of fast heating, short drying time, energy saving, high efficiency, low-temperature sterilization, not burning or singing the product, not destroying biological active substances in the product, being safe and harmless, etc.
Description
One, technical field: the invention belongs to artificial fermentation and prepare the Chinese caterpillar fungus bacterial filament powder technical field, particularly a kind of Chinese caterpillar fungus bacterial filament powder preparation method of microwave drying.
Two, technical background: Cordyceps is the distinctive valuable ingredient of Chinese medicine of China, and because of its growth conditions is peculiar, output is few, so it costs an arm and a leg, supply falls short of demand.The domestic in recent years method cultivation manufacturing Cordyceps fungus powder that has begun to adopt artificial fermentation, but the mycelia of cultivating all is to adopt pyritous drying means to prepare Cordyceps fungus powder, and the temperature of high temperature drying is wayward, it is easy to Cordyceps fungus powder to be dried is burned, the roasting paste, even not burned it also can destroy bioactive substance, thereby reduced the actual medicinal effects of Cordyceps fungus powder.
Three, summary of the invention:
The objective of the invention is at the prior art above shortcomings, and design a kind of Chinese caterpillar fungus bacterial filament powder microwave drying preparation method.The method makes heating object also become heater, does not need heat transfer process, so its homogeneous heating, efficient energy-saving, drying time is short, and cold sterilization can not baked and stick with paste and burned product, do not destroy bioactive substance wherein yet, also pollution-free, better practical value and economic worth are arranged.
Technical scheme is: the microwave drying preparation method of this Chinese caterpillar fungus bacterial filament powder is to separate Cordyceps strain from natural cordyceps, the Cordyceps strain of culture of isolated again, get final bacterium liquid through 2～6 grades amplification culture more subsequently, again final bacterium liquid is removed by filter filtrate and get filter cake, it is characterized in that filter cake is removed moisture with the method for microwave drying, get Chinese caterpillar fungus bacterial filament powder, the microwave drying condition is under 2450 ± 500HZ condition, dry 7～20 minutes.Separate Cordyceps strain and get filter cake up to final bacterium liquid is removed by filter filtrate from natural cordyceps, these processes are prior art, no longer here stating more.Technological core of the present invention is exactly that the filter cake of Cordyceps is removed moisture with the method for microwave drying, gets Chinese caterpillar fungus bacterial filament powder.Microwave drying is hydrone and the fat molecule of microwave in the vibration of high speed frequency of oscillation high speed is dried thing, makes its mutual frictional impact, and produces heat, thereby realize dewatered purpose.
Filter cake of the present invention is removed moisture with the method for microwave drying, it is fast that it has heat time heating time, drying time is short, efficient energy-saving, cold sterilization can not baked and stick with paste and burned product, can not destroy bioactive substance wherein yet, series of advantages such as safe and harmless, it efficiently solves a technical barrier in this production field.
Four, the specific embodiment:
Embodiment 1: isolate Cordyceps strain from natural cordyceps, again these isolating Cordyceps strains are cultivated in culture medium, subsequently again these strains after through 2 grades amplification culture final bacterium liquid, final bacterium liquid is removed the filter cake of filtrate with filtering method, and filter cake is to get Chinese caterpillar fungus bacterial filament powder under the condition of the 1950HZ left and right sides after dry 20 minutes at microwave condition.
Embodiment 2: from natural cordyceps, separate Cordyceps strain, again these Cordyceps strains are cultivated, strain after again these being cultivated subsequently after through 6 grades amplification culture final bacterium liquid, final bacterium liquid is removed the filter cake of filtrate with Filtration, and filter cake is to get Chinese caterpillar fungus bacterial filament powder under the condition of the 2950HZ left and right sides after dry 6 minutes at microwave condition.
Claims (1)
1. the microwave drying preparation method of a Chinese caterpillar fungus bacterial filament powder, it separates Cordyceps strain from natural cordyceps, the Cordyceps strain of culture of isolated again, get final bacterium liquid through 2～6 grades amplification culture more subsequently, again final bacterium liquid is removed by filter filtrate and get filter cake, it is characterized in that filter cake is removed moisture with the method for microwave drying, get Chinese caterpillar fungus bacterial filament powder, the microwave drying condition is under 2450 ± 500HZ condition, dry 7～20 minutes.
