Embodiment 1

[0031] 1) Collect wild Cordyceps militaris in Changbai Mountains, isolate Paecilomyces militaris species, carry out liquid expansion, shaker culture for 7 days, and obtain Paecilomyces militaris species liquid.

[0032] 2) Inoculate the strain prepared in step 1) on tussah silkworm chrysalis soaked in 0.7ppm ozone water for 15 minutes. The inoculation point is from the tail to the head of the pupal body, and each silkworm chrysalis is inoculated with 0.4ml.

[0033] 3) After inoculation, under the conditions of 25°C, 1000 Lx light, and 12 hours of light per day, culture for 60 days, the fruiting body of Cordyceps militaris grows and obvious ascus shells are formed on the upper part of the fruiting body, that is, high-quality Cordyceps militaris is cultivated.

[0034] 4) Harvest the Cordyceps militaris obtained in step 3), place them in a microwave tunnel with a wavelength frequency of 2450 MHz, and a temperature of 50°C to 60°C to dry until the moisture content reaches 7%.

...

Embodiment 2

[0038] 1) Collect silkworm pupae and soak them in 0.8ppm ozone water for 10 minutes.

[0039] 2) Inoculate the sterilized silkworm chrysalis with the Paecilomyces militaris seed solution prepared in step 1) of Example 1. The inoculation point is from the tail to the head of the pupal body, and each silkworm chrysalis is inoculated with 0.2ml of the bacterial solution.

[0040] 3) After inoculation, culture for 70 days under the conditions of 25°C, 1000 Lx light, and 12 hours of light per day. When the fruiting body of Cordyceps militaris grows and obvious ascus shells are formed on the upper part of the fruiting body, high-quality mulberry pupae are obtained. Cordyceps.

[0041] 4) Harvest the mulberry Cordyceps militaris obtained in step 3), place it in a microwave tunnel with a wavelength frequency of 2450 MHz and a temperature of 50°C to 60°C, and take it out when the moisture content is 8%.

[0042] 5) The dried Cordyceps militaris in step 4) is coarsely crushed to 40 ...

Embodiment 3

[0044] 1) Collect tussah silkworm chrysalis and soak them in 1.0ppm ozone water for 20 minutes.

[0045] 2) Inoculate the sterilized tussah silkworm chrysalis with the Paecilomyces militaris solution prepared in step 1) of Example 1. The inoculation point is from tail to head at the pupal body, and each silkworm chrysalis is inoculated with 1.0 ml of the solution.

[0046] 3) After inoculation, culture for 80 days under the conditions of 18°C, 1000 Lx light, and 12 hours of light per day. When the fruiting body of Cordyceps militaris grows and obvious ascus shells are formed on the upper part of the fruiting body, high-quality tussah pupae are obtained. Cordyceps.

[0047] 4) After harvesting the Cordyceps militaris cultivated in step 3), place it in a microwave tunnel with a wavelength frequency of 2450MHz and a temperature of 50°C~60°C to dry until the moisture content is 5%.

[0048] 5) The dried tussah Cordyceps militaris obtained in step 4) is coarsely pulverized to 20...

Abstract

The invention provides a preparation method of cordyceps militaris nano powder, comprising the following steps: 1) separating wild cordyceps militaris paecilomyces, and purifying to prepare cordyceps militaris strain liquor; 2) selecting health and live insect pupae, sterilizing by ozone for later use; 3) infecting the insect pupae sterilized in step 2) by the strain liquor prepared by step 1); 4) performing bionic cultivation on infected insect pupae obtained in step 4) to obtain cordyceps militaris cells integrating pupalcells and sporocarps into a whole; and 5) carrying out microwave drying and nano grinding on the obtained cordyceps militaris cells cultured in step 4) to obtain the cordyceps militaris nano powder. The preparation method of the invention has low investment and low energy consumption, the prepared cordyceps militaris nano powder is not polluted by sterilization process, and the fineness of the powder can reach nano level, thus the powder can keep original functionalactivity and is easily absorbed by a human body.

Description

technical field [0001] The invention belongs to the field of health food processing and production, and relates to a production method of Cordyceps militaris nanopowder. Background technique [0002] Cordyceps militaris, like wild Cordyceps sinensis, is rich in various bioactive substances such as cordycepin, cordycepic acid, adenosine, polysaccharides, SOD, etc. It is also rich in amino acids, fatty acids, vitamins, mineral elements and trace elements. It has the effects of improving immune regulation, anti-tumor effect, regulating blood lipid, blood sugar and blood pressure, sedative effect, androgen-like effect, anti-fatigue effect, anti-aging effect, beauty and anti-oxidation effect, and has the functions of nourishing kidney and lung, protecting heart and Nourishing and strong function. There are many Cordyceps militaris health products, health food, food seasoning and compound Chinese medicine etc. on the market at present. All Cordyceps militaris products are compos...
