What is the difference between 30-head and 80-head fish maw?

Fish maw is a precious nourishing food, suitable for men and women of all ages. Generally, when you go to buy it, the seller will ask you how many heads you want. So what is the difference between 30-head and 80-head fish maw?

1. What is the difference between 30-head and 80-head fish maw?

The difference between 30-head and 80-head fish maw is that 30-head fish maw means there are about 30 pieces of fish maw per 500g, while 80-head means there are about 80 pieces of fish maw per 500g. Generally, the smaller the head number of fish maw, the larger the size of the fish maw and the richer the nutrition. Of course, this is not entirely the only factor that determines whether fish maw is good or bad.

2. How to choose fish maw?

Since fish maw is a dried product made from the swim bladders of sciaenid fish and eels, its output is not high, and relatively speaking its price on the market is also rather expensive, so many unscrupulous merchants use other cheaper materials to make fake fish maw. The most common ones include rabbit ears, pig skin, squid, and even the raw rubber used to make shoe soles. Therefore, when choosing, you can refer to the following methods:

1. Look at the texture

Generally, good-quality fish maw has a clean texture and a pale yellow color, and is semi-transparent, with no residual blood vessels or bruised blood; if the quality of the fish maw is relatively poor, its texture will be rather murky, and obvious residual bruised blood can be seen.

2. Smell the odor

Better-quality fish maw smells very faint, without a strong fishy smell or stench; if the quality of the fish maw is relatively poor, you can smell an obvious fishy odor, or even a stench.

3. Feel whether it is dry or wet

Generally, better-quality fish maw is relatively dry, and when held against the light you can see your fingers through it; while poor-quality fish maw, when illuminated by light, is transparent around the edges and murky in the middle. This kind of fish maw generally tends to become moldy and deteriorate.

4. Choose the age

Generally, the darker the color of the fish maw, the older it is, while aged fish maw has a lower collagen concentration, and its nutrients are more easily absorbed by the human body, making it more nourishing.
