High-quality fish glue is not fishy, not gurgling, not dissolving, slippery and refreshing after stewing. Most of the general quality is only used for cooking soup, but high-quality and high-quality fish glue can be used to make dishes. To buy high-quality fish glue, we mainly start from the following aspects:

1, variety

According to the variety, the top fish glue ranks in turn as white flower glue, yellow flower glue, sole glue and door eel glue. Authentic yellow gum and white gum are rarely seen in the market. Sole gum can be divided into money belly, spider belly, sole gum, big ear, Taishan, red chicken, red mouth and so on. In addition, there are many kinds of fish glue, such as Beihai, Douhu, Shuangya, Jinlong and Yeyan.

2. Color

It is better to have a clean texture, no blood and blood stasis, translucent, light yellow and bright color.

3. Size and thickness

The bigger the size and thicker the glue body of the same kind, the better its quality. The so-called "one or two glue for ten Jin of fish". It can be seen that a fish glue weighing several times, the fish body will weigh dozens of pounds.

4. Dry humidity

The drier the gelatin is, the better. When you buy gelatin, you can take a photo under the light. If the gelatin is translucent, the quality is better. The color of the gum with high humidity is dark and dull, and even some gums are not completely dried when they are dried. Generally, the periphery is transparent and the center color is turbid, which is the "flower heart". Avoid choosing. The longer the time, the flower heart will be moldy, and it will smell bad after soaking, so it is not allowed to eat.

5. Male and female selection

The fish glue is divided into male and female. The fish glue is saddle-shaped, thick in the middle of the belly, and thin on both sides, with a V-shaped stripe. The texture is firm, thick, dry and light, golden yellow is the best, and translucent is the top grade. After cooking, it is firm and elastic. As for the "wide belly", it is slightly round and flat, shaped like a wavy plate, with a horizontal or wavy body, which is thin, easy to dissolve after cooking, soft in taste and cheaper in price. Fish glue male is better than fish glue female.

6. Smell

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

7. Year

The darker the color of fish glue, the older it is. The advantage of aged fish glue is that the concentration of glue is reduced, which makes the nutrients more easily absorbed by the human body and more nourishing. Old fish glue of the same quality is better than new glue.
