Eight ways to distinguish real from fake fish maw

It's actually quite simple to distinguish real fish maw from fake, but you must consider all 8 methods below, and not just focus on one aspect. The following 8 aspects are also the eight ways to identify real and fake fish maw.

1. Translucency

This is the most basic characteristic of fish maw. If fish maw is not translucent, it is generally fake. How to check translucency? The simplest way is to hold it against the light and see if you can see your fingers through it, meaning it should feel transparent. Fake fish maw has no translucency; its texture is very dull.

2. Flesh Texture and Grain

Each different variety of fish maw has its unique texture and grain, although some fish maws have similar grains, such as "Chi Zui" and "Beihai Gong Du," which both have delicate and smooth grains. If there are no grains, and the fish maw appears stiff and blocky, it might be fake. Additionally, older fish maw tends to have clearer, more delicate, and more beautiful grains, giving a sense of its age and history.

3. Distinctive Features

Each type of fish maw has its own unique characteristics. When choosing fish maw, you should know what variety you are selecting and what its characteristics are. For example, the fake Zhanjiang Chi Zui in the picture does not have the "nasolabial folds" and "water outlet." Therefore, it is fake. The one in picture 4 is a real Zhanjiang Chi Zui.

4. Soaking Method

Real fish maw remains intact after soaking, while fake fish maw will show unevenness. Of course, not all fish maws are suitable for soaking; some with a brittle texture are not, while those with strong韧性 (resilience) are suitable for soaking.

5. Breaking Test

This method is simple: try breaking the fish maw to see if it breaks easily. Generally, good quality fish maw will feel like a lotus root whose fibers still connect when broken, rather than snapping into two pieces instantly. However, thicker and larger pieces of fish maw are difficult to break.

6. Color Difference

Each variety of fish maw has its own distinct color. When choosing a particular variety, you can first look up pictures of that variety to see if there is too much color difference between what you're selecting and the reference images. For example, if the color is very yellow, appears dull from bleaching, and lacks the natural, woody tone of aged fish maw.

7. Stewing Method

Real fish maw remains relatively intact when stewed, but the stewing time is not arbitrary. Some real fish maw can be stewed for 1 hour, others for 3 hours. Within an appropriate time frame, real fish maw will not easily melt, disappear, or disintegrate when stewed. Fake fish maw, however, will show very strange signs such as bubbles, hard clumps, and uneven textures when stewed.

8. Details

This primarily refers to the blood vessels and fish oil in fish maw, which are essential details for natural fish maw. However, not all fish maws will have as many blood vessels as shown in the picture. If it's aged maw, there will be fewer blood vessels because they gradually detach and disappear over time. Nevertheless, common fish maw, especially those with good stickiness, will more or less have some blood vessels. Of course, the specific situation for each variety is different. Other details also include the grain of each fish maw; some have horizontal grains, others have vertical grains, and some varieties have indistinct grains. Therefore, for the specific fish maw you are choosing, you should refer to pictures of that variety to confirm if it is genuine fish maw.

Frequently Asked Questions (FAQ)

Q: How many types of fish maw are there?
A: Common types include Money Maw, Spider Maw, White Flower Maw, Zhazhi Maw, Chi Zui Maw, Guang Du, Stone Du, and Duck Bubble Fish Maw, among over a dozen varieties. The top grades are Money Maw and Spider Maw, which are the most valuable in the recycling market; White Flower Maw is in the middle; ordinary Duck Bubble is relatively cheaper.

Q: How do you differentiate wild fish maw from farmed fish maw?
A: Wild fish maw has coarse fibers, thick collagen, and pulls out silken strands after cooking; farmed fish maw has fine fibers and is thinner after cooking. Wild fish maw is usually 2-3 times more expensive than farmed fish maw.

Q: Is older fish maw always more valuable?
A: Wild aged fish maw usually becomes more valuable with age, especially Money Maw, Spider Maw, and White Flower Maw that are over ten years old. The collagen quality transforms over time, becoming fragrant instead of fishy, and developing a shiny, translucent appearance. However, the value appreciation of aged farmed fish maw is limited.

Q: How can I store fish maw to prevent mold?
A: Use a sealed iron box with food-grade desiccant, store it in a cool, dry place, and avoid direct sunlight. Take it out to air for a day every six months. Absolutely avoid storing it in the refrigerator (humidity can cause mold).
