True and fake shark fins can be distinguished from four aspects: color, taste, stickiness, and shape.

1. Stickiness

1. Real shark fin has strong stickiness. For example, when making shark fin rice, the rice will stick to it and will not fall off easily.

2. Fake shark fins are not as sticky as real shark fins. For example, if shark fins are cooked with rice, the rice will easily fall off if the fake shark fins are rubbed with hands.

2. Shape

1. The shape of a true shark fin is the filamentous cartilage found in sharks. One end is round and thick, while the other end is tapered, similar to a needle, with a fin in between. There are meat eaters who want to connect.

2. Because fake shark fins are artificial, they are either thick at both ends or pointed at both ends, and there is no wing meat, no wing meat, and the artificial cut surfaces can be clearly seen.

3. Color

1. Real shark fins are white before being cooked, but after being made into food, they will become translucent or fully transparent and look very plump. .

2. Because the fake shark fin is artificially made from synthetic vermicelli, it appears golden yellow and remains light yellow after cooking.

4. Taste

1. Real shark fin is rich in collagen and has a very good texture and toughness. It will not deform or break no matter how you twist it.

2. Fake shark fins have a crisp texture and will break if you break them with your hands. They are not as tough as real shark fins. This is mainly because fake shark fins contain isinglass.
