Nest; Pure bird's nest is incomplete whether it is soaked or viewed under the lamp.
Transparent, but translucent.
Smell: Bird's nest has a unique smell, but it has no strong smell. It smells especially fishy.
Those with fishy or greasy smell are fakes;
Bubble: Bird's nest will expand after soaking in water, and will be pulled by silk strips after softening, with poor elasticity.
A pull is a fake; Pinch with your fingers, and you can get an inelastic paste.
It is also fake; The real bird's nest is still clear after soaking in water, while the fake bird's nest
Because there are other ingredients in the nest, they will dissolve in water after entering the water, resulting in water color mixing.
Those with low foaming rate are also fakes.
Burning: ignite dried bird's nest slices with fire. If they were real bird's nests, they would never produce any.
Sparks splash violently.
Touch: The real bird's nest is made of Jin Siyan saliva, and it feels obviously rough. When choosing bird's nest, we must look carefully. Now many bird's nests on the market are faked, and the means of counterfeiting are becoming more and more clear, which is not basically indistinguishable by experts.
The fake methods of bird's nest are: adding glue, mixing water, chemical bleaching, dyeing red blood swallows,
Here are some ways to tell the true and false bird's nest:
1, look at the appearance
Those that look full and sell well are basically glued. Don't even look at them. They must be fake. Imagine that the bird's nest is a nest made in Jin Siyan, and it will bring some impurities such as swallow hair or branches. How can it be so perfect after artificial picking?
2. Look at the size and compare the prices
A single bird's nest is basically between 3.8 and 8 grams. The price is also based on the size of the lamp and the picking time! For example, a single bird's nest in a drugstore or specialty store is between 5 grams, and the price is around 50 yuan/gram. The salesgirl also said to you, "If you want to buy it, I can give you an internal employee price." It is conceivable that the quality of bird's nest is not much better. Someone must be manipulating it.
3. Look at the packaging and preservation
Good bird's nest can be stored for three years at room temperature, and it doesn't need to be put into refrigerator or vacuum packed. If the salesgirl tells you that "the bird's nest must be kept in the refrigerator after it is bought" and also stipulates that it should be eaten within a certain period of time, will it affect the nutritional value of bird's nest? Then this bird's nest must be mixed with glue or water to achieve the purpose of weight gain. So is vacuum packaging!
Step 4 smell it
Bird's nest itself has a faint fragrance. If you smell strong fishy smell or strange smell, it must be a bird's nest with problems. It is either chemically bleached or glued or something.
5, look at the hair (bubble hair)
The so-called hair, that is, dried bird's nest will absorb water after soaking in water, making it swell up. Generally, the hair of pure bird's nest is 8~ 13 times (for example, 3 grams of dry pure bird's nest will reach 24~36 grams after soaking). Bird's nest with glue or water is generally small, about 5~8 times, because they all pass through glue and water. It is not a pure nest.
Step 6: Eat
The stewed bird's nest is silky in shape, with different lengths and thicknesses; There will be a faint protein smell, not pungent; The color is translucent light milky yellow, not too white; It tastes smooth.
7, fake blood swallows
It is particularly emphasized here that all the blood swallows on the market are fake. Because the global annual output of blood swallow is less than 10 kg, not to mention the price. Basically, they were sold by powerful and rich people. How could they be bought by us ordinary people? Think about it.
80% of the blood swallows in the market are inferior bird's nest made of "bird droppings", which will not fade after soaking and stewing, and harmful components have penetrated into the bird's nest. Dare you eat them?
Please combine the above 7 points to avoid buying fake bird's nest, which is harmful to eat and a pity to abandon it! ! !
Special reminder: don't think that the bird's nest bought in Indonesia, Thailand, Malaysia, Hong Kong, Singapore and other places must be true. Because the origin of the holiday is Indonesia, Thailand and Malaysia, and the bird's nest in Hong Kong and Singapore is also imported from these three places, the seller simply doesn't know that there is a holiday! Don't make this mistake. . .
