Many fake shark fins are made of low-cost winter powder or fish skin and gelatin, and some black-hearted goods are bleached with industrial hydrogen peroxide. Eating too much can not only nourish health, but also easily cause negative effects on the body. Therefore, before people buy or eat, they can distinguish them according to five steps: looking after, smelling, tasting, tearing and pulling.

Distinguishing between true and false shark fins is often a favorite topic for many gourmets to discuss. Some people have eaten shark fins for many years, but they don't know that they are eating artificial "fake shark fins". In fact, it is not difficult to distinguish between true and false shark fins and shark fins made by water or medicine. Just follow the following five steps:

1. Look: observing the color and transparency of shark fins, it is true that shark fins are natural in color and rich in layers; The shark fin with poor quality is transparent, white and has no layering, which looks like the texture of plastic.

2. Smell: Shark fins foamed with liquid medicine or bleached with hydrogen peroxide will leave some medicinal flavor.

3. Taste: The shark's fin with natural water hair tastes delicate, with distinct filaments and Q in the soft. The shark's fin with drug foam is hard to bite, hollow inside and tastes like plastic.

4. Tearing: The shark's fin foamed with pure water is clear, while the shark's fin foamed with medicine is thicker and can't be torn with chopsticks.

5. Pull: The shark fin foamed with general natural water is more elastic, and it will be as elastic as a rubber band after cooking; The shark's fin, which rises with drugs, will break when pulled because of the destruction of the tissue.

When it comes to the method of making fake shark fin, Wang Jia Zhuang said that in addition to distinguishing between true and false, the foaming process of shark fin is also very important. If it is foamed with natural water, it will expand to 2 to 2.5 times the weight before foaming; If the shark fin is foamed with liquid medicine, it can be expanded to 3 to 6 times the original weight. In contrast, of course, the shark fin foamed with liquid medicine can also save a lot of costs, and the speed is much faster than that of natural water.

The foaming of shark fin is a very important part in the cooking process, which not only affects the delicacy of the dishes eaten by guests, but also affects the health of consumers. For example, Taipei Top Shark's Fin Restaurant or Xing Shark's Fin Restaurant where I am currently working, we insist on using pure natural water to foam shark's fin, so as to preserve its delicacy and colloid.

Its nature is also different!

First, the false wing is not fire-resistant. Although it is thick and needle-shaped, it can be boiled and softened at once, and it tastes like jelly, and it will break in one bite; The real wings are refreshing and elastic.

Second, the fake wings are placed on the table and rubbed with your fingers, and rice objects fall; True wings have elastic fibers.

Third, the false wing is pulled by hand and easily broken; And the real wings need to be broken by force. Fourth, the pseudo-winged needle is particularly crystal clear after soaking in water.

Look carefully at the above items. The difference between true and false shark fins is a world of difference. Real shark's fin is delicious, with excellent taste and endless aftertaste; Fake shark's fin tastes too bad, pale and tasteless. No wonder some people say that eating shark's fin is like eating vermicelli. It is very likely that you have eaten fake shark's fin. I hope you can distinguish the authenticity and taste the real Chinese delicious food.
