The order of top fish maws is as follows: white glue, yellow glue, sole glue and eel glue. Authentic yellow glue and white glue are rarely seen in the market. Sole glue can be divided into money belly, spider belly, sole glue, big ears, Mount Tai, red chicken, red mouth and so on. In addition, there are many kinds of fish glue, such as Beihai, Douhu, Ya Shuang, Jinlong and Wild Swallow.

Step 2 color

Clean texture, no blood stasis, translucent, light yellow and bright color are preferred.

3. Size and thickness

The bigger and thicker the colloid of the same kind, the better the quality. The so-called "ten pounds of fish and one or two gums". It can be seen that a few kilograms of glue, the fish body has dozens of kilograms.

4. Dry humidity

The drier the glue, the better. You can take a photo under the lamp when you buy glue. If the glue is translucent, the quality is better. Chewing gum with high humidity is dark and dull, and even some chewing gum is not dry enough. Generally, the periphery is transparent and the center color is turbid, which is the "flower heart". Avoid choice. The longer the time, the flower heart will be moldy, and it will smell after soaking, so it is not allowed to eat.

5. Male and female choices

Flower glue is divided into male and female. Flower gum is saddle-shaped, with a thick belly in the middle and thin sides with V-stripes. The texture is solid, thick, dry and light, golden yellow and translucent, which is the top grade. It is firm and elastic after cooking. As for the "wide belly", it is slightly round and flat, shaped like a wavy plate, horizontal or wavy, thin, easy to dissolve after cooking, soft in taste and cheaper in price. Rubber men are better than rubber women.

Smell

High-quality flower glue, fishy and odorless. There is no fishy smell after stewing, and it is refreshing and slippery, but it is best not to slip.

7. Glue Age

The darker the glue is, the longer it is. The advantage of aged gum is that the concentration of gum is reduced, which makes nutrients more easily absorbed by human body and has a nourishing effect. Old rubber of the same quality is better than new rubber.

8. Country of origin

The degree of pollution in the waters of the origin also affects the quality of the flower glue, but it is not the current waters, but the water quality at that time when the flower glue was taken out of the fish belly. This can't be verified accurately, but it is also a standard.
