How to choose snow clam

There are three aspects to consider when purchasing snow clam: first, look; second, taste; and third, soak it. High-quality snow clam is white and shiny, waxy, slightly transparent, and has a fat-like luster. It feels smooth to the touch, has a fishy smell, tastes slightly sweet, and feels sticky when chewed. The swelling rate is as high as over 55 times. The false snow clam does not have the above characteristics.

In addition, price is also an important criterion. Due to the cost limitations of raw material selection and production technology, high-quality snow frog is generally expensive. The general selling price should be more than 7 yuan per gram, which is more reasonable. If the price is lower than 5.5 yuan per gram, it is basically a low-quality product. If it is 1-3 yuan per gram, it must be a fake, which may be bullfrog or toad oil. Taking it is not only useless to the body but also very harmful.

There are two ways to identify the true and false snow clam.

1. Appearance: The appearance of real frog oil is yellow or light yellow blocky and translucent when it contains 20% moisture. The dry frog oil without moisture is yellow or yellow mixed with brown, and the wax is obviously translucent. The fake ones are mostly made of bullfrog intestines to make crushed oil, which is yellow to light yellow, lighter in color than the real ones, and does not have the black vascular network unique to the real ones.

2. Identification by immersion in water: Real frog oil has strong water absorption, and its volume increases when immersed in water. Moreover, due to the large amount of water absorbed, the tissue structure of the frog oil is broken and becomes an enlarged sponge. False frog oil absorbs little water and expands slightly in volume. Due to the small amount of water absorbed, the tissue structure is not destroyed. Therefore, after immersion in water, the edges of the tissue blocks are neat and consistent and will not swell into a clumping shape. Generally, the false snow clam becomes shaped like duck intestine after foaming.
