CATDOLL : CATDOLL: What insects are suitable for breeding in the north?

What insects are suitable for breeding in the north?

There are many

There are more than 1 million species of insects in the world, and more than 500 species can be found.

Experts predict that by the 21st century, insects will become second only to

The third largest source of protein for microorganisms and cellular organisms is insects.

Many species, large quantity, wide distribution, fast reproduction, high protein, low fat

, low cholesterol, reasonable nutritional structure, less meat fiber, and easy to absorb

, It has outstanding advantages and is superior to plant protein, and has attracted attention from all over the world.

The protein content of insects is higher than that of beef, pork, chicken and fish.

For example, dried wasps contain about 81% protein, honeybees 43%, and cicadas 7.

2%, grasshoppers 70%, crickets 65%, rice locusts 60.08%,

Tussah silkworm pupae 52.14%, fly maggots 60.88%, mealworms 63

．19%, Dingshi Polyrhachis ant Wang Shihong 64．50%, Red-breasted Polyrhachis ant 58

． 60%, etc., and the protein is rich in various amino acids needed by the human body.

Acids, especially lysine, threonine, methionine, etc. that cannot be synthesized by themselves

In addition, the insect body also contains a small amount of fat, sugar, multiple vitamins and

Minerals, etc. Chitin can also be extracted from insect skin and blood

Extraction of antimicrobial peptides, etc.

There is a bright future for developing insect food. Mexico and Japan, which started early,

Japan, Germany, France, the United States, Belgium and other countries have produced a variety of

Insect foods, such as preserves, biscuits, bread, candy, canned food, sauces,

In Japan, the Insect Utilization Promotion Committee was established.

In 1992, the actual market size of insect utilization technology in Japan was 2

60.9 billion yen, and it is estimated that it will reach 82.63 billion yen in 10 years.

.

The custom of eating insects in my country has a long history and is more popular in ethnic minority areas.

my country is a vast country with rich resources and abundant insect resources.

Locusts and cicadas were once exported for foreign exchange.

At the seminar, my country's Ministry of Health officially listed ants as a new resource development project.

my country has also proposed the establishment of a national resource insect industry promotion committee.

To promote the development and use of insect food and medicine.

In celebration of the 50th anniversary of the founding of the Entomological Society of China,

At the National Resource Insect Industrialization Seminar, a grand insect

Insect feasts have greatly expanded the impact of insects that can be eaten.

Food and medicine can be turned from harm to treasure, achieving multiple goals at one stroke.

A wave of enthusiasm for establishing insect food industries, and corresponding insect food and medicine

Will keep appearing.

The dominant food in the 21st century is functional food, and insect food is becoming

It is a typical functional food. Insects are a large category with great development potential.

It is a treasure trove of biological resources and nutrients that can be used as food and medicine, and can be used as a

Advanced nutritional products and effective medicines for the elderly, teenagers and children.

Mealworms (yellow mealworms), whose pupae are high-protein food, are very popular in the south.

Please tell me how to cultivate silkworm chrysalis

Cordyceps militaris, also known as northern cordyceps, is a complex of insects and fungi formed after the pupae of insects are infected with cordyceps fungi. It has similar medical and health benefits as natural cordyceps. To produce silkworm pupa cordyceps, you only need a plastic box, special strains of cordyceps (i.e. strains specially domesticated to grow well on silkworm pupae), and a small amount of special nutritional antifouling additives for cordyceps. The main production technology is briefly introduced as follows:

1. Main raw materials

1. Silkworm pupae. Fresh silkworm pupae that have just broken out of their cocoons should be dried for easy storage and transportation to prevent them from becoming moldy or being contaminated by harmful bacteria.

2. Plastic incubator (box). Food-grade, non-toxic, translucent or transparent incubator with a lid should be used.

3. Anti-fouling additives for Cordyceps militaris. It is composed of nutrients required for the growth of Cordyceps militaris hyphae and appropriate additives to prevent contamination by foreign bacteria. When using this agent, there is no need to purchase raw materials such as peptone, glucose, vitamins, etc., which solves the problems that some growers may encounter during cultivation due to lack of cultivation experience, such as improper nutrient ratio of the culture medium, failure to change color, failure to grow grass, and serious pollution.

4. A small amount of rice. Rice that meets edible standards and is not moldy or contaminated by harmful substances should be selected as the inoculum.

5. A small amount of plastic bags. Polypropylene or polyethylene plastic bags can be used as containers for soaking and sterilizing dried silkworm pupae.

2. Production Method

1. Preparation of culture solution. 1 kg of fresh silkworm pupae, 1 bag of nutrient antifouling agent for Cordyceps cultivation, 1.5 kg of water (the ratio of fresh silkworm pupae to water is 1:1.5). Or 2 kg of dried silkworm pupae, 2 bags of nutrient antifouling agent for Cordyceps cultivation, 6 kg of water (the ratio of dried silkworm pupae to water is 1:3). According to the above formula, first weigh an appropriate amount of hot water at about 50°C and pour it into a clean plastic basin or porcelain basin, then unpack the nutrient antifouling agent for Cordyceps cultivation and put it into the hot water and stir it repeatedly until it dissolves to form the nutrient solution. After preparing the nutrient solution, you can weigh the silkworm pupae according to the ratio of silkworm pupae to nutrient solution and put them into plastic bottles, plastic boxes or plastic bags for sterilization.

2. Processing of silkworm pupae. Now, let's take dried silkworm pupae as an example to introduce the processing method of silkworm pupae: after preparing the nutrient solution according to the above formula, you can weigh the dried silkworm pupae in a ratio of about 1:3 to the nutrient solution and pack them into plastic boxes or boxes. When packing, you can weigh 30 grams, 50 grams or 100 grams of dried silkworm pupae according to the capacity and put them into the plastic culture box (box). After packing, pour the nutrient solution and seal it to sterilize. If you use a plastic bag as a container to process silkworm pupae, put the silkworm pupae in, add the nutrient solution, and then squeeze the plastic bag to expel the air, so that the nutrient solution can submerge the dried silkworm pupae. Tie the bag tightly and put it into the sterilizer for steaming and pre-wetting. If you put 100 grams of dried silkworm pupae in a bag, you should add 300 ml (i.e. 300 grams) of nutrient solution to the dried silkworm pupae bag, then expel the air to let the nutrient solution submerge the silkworm pupae and slightly tighten the bag. Due to the different water absorption of dried silkworm pupae, if the water absorption is large, you can add nutrient solution appropriately. On the contrary, the amount of nutrient solution added can be reduced and adjusted according to actual conditions.

After all the silkworm pupae are packed according to the above method and sealed with nutrient solution, they can be placed in a sterilizer for heating and sterilization. When the temperature reaches 100℃, keep it for about 1 hour to end the sterilization. Wait until the temperature drops to about 30℃ and take out the silkworm pupa bags. If there is excess nutrient solution, turn the silkworm pupa bags upside down to let the nutrient solution flow out. After they are completely cooled, they can be moved into the inoculation room for inoculation.
