In the season of eating shrimp, after eating shrimp for so many years, do you really eat shrimp? Teach you an ancestral shrimp guide! Crayfish (scientific name: Procambarus clarkii): Also known as crawfish, red crawfish, and freshwater crayfish. It resembles shrimp and its shell is hard. The adult is about 5.6 to 11.9 centimeters long, dark red, and the carapace is nearly black, with a wedge-shaped stripe on the back of the abdomen. The larvae are uniformly gray, sometimes with black ripples. Chewing narrow. The middle of the carapace is not separated by a mesh-like void, and the carapace is distinctly granular. The frontal sword has a nick on the side spine or frontal sword. Crayfish has a high protein content and is soft and digestible. It is an excellent food for people who are frail and need to be nursed back to health. Shrimp is also rich in magnesium, zinc, iodine, selenium, and magnesium. The activity has an important regulatory role, can protect the cardiovascular system, it can reduce blood cholesterol levels, prevent arteriosclerosis, while also expanding the coronary artery, is conducive to the prevention of hypertension and myocardial infarction.
Shrimp Raiders first type: points male and female eat crawfish for so many years, many people should not know the crayfish there is a distinction between male and female, let us together long knowledge. Prawns: There are harder calves on the abdomen. Female shrimp: There is no harder calf in the abdomen.
Shrimp Raiders II: see size
Everyone who eats crayfish all the year round knows that the bigger the crawfish is, the more expensive it is to sell. Here's a comparison of the items that are common in life. Take everyone to see how big the crayfish are.
Shrimp Raiders third type: see the clean
Crayfish industry insiders know that to judge a shrimp is not clean, it depends on shrimp enough to be white enough. Because the cockroach is the crayfish's respiratory organ, impurities in the water are filtered through the cockroach. Shrimp raised in shallow waters are black because of the impurities in the water. Only the shrimps bred in the deep-water lakes will have a clean and clean heart.
If the growing environment is not clean, it will not be possible to wash off the impure inner prawn. So how do you judge what kind of shrimp is worthwhile?
Shrimp Raiders fourth type: peel shrimp Dafa
Hold the shrimp tail and gently turn it. The shrimp yellow tail is easily peeled off.
Shrimp Raiders fifth type: bite the head to eat yellow
Shrimp yellow is rich in nutrients and is the most precious place on the shrimp body. It is generally located in the head of shrimp. How to eat shrimp yellow is the best?
According to the concentrated position of the shrimp yellow bite, crayfish sauce mixed with delicious shrimp yellow, this taste, how a cool! (It should be noted that only shrimp that has gone too far can bite it. The stomach capsule on the front of the shrimp head is inedible.)
Shrimp Raiders sixth type: peel shrimp tail
The lobster is delicious, but the shell is hard to peel. Let's take a look at how the ancestral Raiders are stripped: hands pound the crust into pieces and squeeze the shells of the shrimp's tail. After peeling off, it's easier to do it. (Be careful, don't hurt your finger on the shrimp shell.)
Shrimp Raiders 7th Formula: Discriminating between fresh shrimp and frozen shrimp The production of crayfish in winter is relatively small, and some merchants will sell some of them in the winter. How can the frozen shrimp and fresh live shrimp be distinguished?
Frozen shrimp: The shrimp body is wrinkled and tastes fresh; Fresh shrimp: The shrimp body is plump and Q tastes.
Shrimp Raiders eighth type: shrimp line
Most businesses selling crayfish will remove the shrimp line before making it, but doing so will make the shrimp loose and affect the taste. In order to taste the most delicious taste, food eaters can come to get the method of shrimp line. Hold the shrimp yellow, tear open the shrimp body and expose the shrimp line. After finding it, you can pick it out. ~ Professional food products generally can extract a whole piece of shrimp line. ~ The shrimp line removes the white one on the back. Do not throw the skin, but that is the place with the most astaxanthin in the shrimp. Astaxanthin has antioxidant, anti-aging, anti-tumor, prevention of cardiovascular and cerebrovascular diseases.
Shrimp Raiders 9th type: eat fresh shrimp
Professional food goods know that crayfish is divided into shrimp and red shrimp. Green shrimp lived green and red shrimp was slightly darker than shrimp. Generally, only fresh shrimp can be eaten before mid-May. At this time, the shrimp just peeled off the shell, the shell was relatively soft, the meat was relatively tender, and the nutritional value was high. After being cooked, the red color is lighter and slightly yellowish.
The above is the entire contents of the shrimp attack. Does it mean that eating crayfish is a science?

Plant extraction process
1. Select plants/herbs. No more than ancient prescriptions, prescriptions, folk herbs to find. At present, common and uncommon herbs have been studied. At present, it is mostly to increase the amount of medicinal materials to extract and separate components with low content, or to find medicinal plants that have never been studied from miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. The extraction. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (low polarity → high polarity). Daily medicine decoction effective, water and ethanol and other solvents with large polarity, such as artemisinin boiling ineffective extraction with petroleum ether and other solvents with small polarity. Common medicinal materials water/alcohol/ether to go through, separation and identification of more compounds.
3. The separation. This is the most important work. In the solution extracted from the second step, there are dozens of compounds, usually by column chromatography, which is often referred to as the column flushing. It's a lot of work, it's boring, it's low tech. A master's student might do this every day for two years. The column for separating compounds, as shown below, is as large as 2 meters high and as small as 10 centimeters. Change the solvent condition of mobile phase, change the material of column, different conditions and different separation principles of column repeatedly punching, can be separated from the monomer compound.
