Please help me see if the clams are really 50

1. Appearance: The appearance of real forest frog oil is yellow or light yellow lumpy translucent in the state of 20% moisture, and the dry forest frog oil is light yellow or yellow mixed brown, and the wax is obviously translucent; Counterfeit products are mostly made of bullfrog intestines into crushed oil, yellow to light yellow, lighter in color than the real product, and no black vascular network unique to the real product.

2. Water immersion identification: the real forest frog oil has strong water absorption, the water immersion volume increases, and due to the large water absorption, the tissue structure of the forest frog oil is broken, and the spongy body is expanded; False frog oil has a small water absorption, the volume is slightly expanded, and the tissue structure is not damaged due to the small water absorption, so the edges of the tissue block are neat and consistent after water immersion, and will not expand to a clump. Generally, false snow clams are duck intestine-shaped after foaming.

First, it depends on the place of origin, and it is believed that it is produced by the Northeast forest frog (since there is no national standard for the definition of snow clams for the time being, some unscrupulous businessmen will quibble that bullfrogs can also be called snow clams).

The second is to see whether it is dry or wet peeling, that is, hanging dry peeling or raw peeling. The latter is not an inferior product, ** will be cheaper than dry peeled, but the moisture content is as high as 20% 50%, and the medicinal value will be slightly lower than that of dry peeling.

The third is to look at the appearance, with the complete and less fragments as the top.

Fourth, look at the "hair", the more beautiful the snow clams, the higher the soaking rate, like some snow clams that sell more than 250 yuan taels, after soaking can reach a ratio of 1 to 60. Some low-grade clams may only be able to shoot five.

In short, a good snow clam has a white color, thick flesh, and a light fishy smell, and the swelling degree after soaking in water is 1 60.

Quoted from the encyclopedia, I don't know if you can judge you by the point of "having a light fishy smell".

The scientific name of snow clam is "Northeast Forest Frog", which belongs to the amphibian, anceridae, frog family, and frog genus, and is a well-known economic frog species in China.

Snow clam is the Northeast forest frog, known as snow clam because it hibernates for up to 5 months in the ice and snow environment, mainly distributed in Jilin, Heilongjiang, Inner Mongolia (northeast), Liaoning, foreign distribution in Mongolia (east), Russia (Far East), North Korea, Japan (Tsushima Island), snow clam male frog body length 63mm, female frog body length of about 67mm, back ** smooth, back and body side have few and scattered round warts.

Snow clams generally live in humid environments with good vegetation from the hills near the coast to the mountainous areas at an altitude of about 900 meters, and they are agile and can quickly avoid predators, and are not easy to catch.

The main value of snow clams

The Northeast forest frog is widely distributed in Northeast China, and the number is very large, and it can prey on all kinds of insects and their larvae in large quantities, and the food is very large, and the maximum body weight can be reached, which shows that the frog plays a positive role in eliminating agricultural and forestry pests, controlling the occurrence of insect pests, and maintaining ecological balance.

It is also an indicator species of forest environmental changes, a reagent and guardian saint of human living environment, and is very sensitive to changes in fresh water and air quality in the forest environment. The Northeast forest frog is also an important biological gene pool, and if the forest frog goes extinct, humans will lose a lot of available genes.
