Can you eat bird's nest stewed with a little white inside?

Bird's nest stewed is a little white, due to heat expansion and white foam is a normal physical phenomenon, the higher the concentration of natural bird's nest, the more white foam.

The correct way to stew bird's nest.

1. Bird's nest soaking.

Take out an appropriate amount of bird's nest, soak it with pure water, it takes more than 1 hour to completely soak it, if the swallow horn part is relatively large, you can pick out the swallow horn and the hard part to continue soaking, the slightly hard one can be torn by hand in the middle of soaking, which can accelerate its soaking, and the soaking process can be changed to new water, which should be completely soft, can be rubbed by hand, and no hardness is the soaking standard.

2. Tear the bird's nest and pick out the fluff in the bird's nest.

After the soaking is completed, rub the edges, corners and large strips by hand into small silk strips, which can reduce the simmering time and the taste is more uniform, and then rinse with water 2-3 times.

Prepare a special fine-porous double-layer filter to drain the water. Carefully inspect the impurities and bird's feathers hidden in the texture of the bird's nest with small tweezers.

Singled out. 3. Stew bird's nest.

Put the washed bird's nest into the stew pot, the amount of water is not a little more than the bird's nest, about 1 cm, do not add too much water, be sure to completely immerse the stew pot in the water, but pay attention to the water level should not be too high, do not let the boiling water into the stew pot.

When the bird's nest encounters high temperatures, the water-soluble protein in it will be destroyed and the nutritional value will be lost, so it is required to stew in water to ensure that the bird's nest is heated at no more than 100 degrees Celsius.

It retains the fragrance while preserving the precious water-soluble protein.

4. Bird's nest storage.

Cool with plastic wrap.

Cover tightly and place in the refrigerator. The storage time of the stewed bird's nest is 3-5 days.

Bird's nest is a nest made of swiftlet's saliva and fluff, which is rich in protein, and when stewed, the temperature is too high to emit white foam, so the stewed bird's nest is a little white and can be eaten.

Why is there white foam in stewed bird's nest?

Today's question looks a little different, and recently a new nest friend has asked me very sadly, is bird's nest just swallow's saliva?

Haha, have you ever been entangled in the fact that "such an expensive thing is just the saliva of swiftlets"?

The ancients gave the saliva the nickname "Jinjin Jade Liquid", and even took the word "live" from the tongue with water. The saliva of swiftlets is especially high in nutrients, and the ingredients in it can help improve the body's resistance, nourish **** and regulate the respiratory system, so that the body functions can "live" again.

The saliva of swiftlets is formed by condensation in the air, and when heated, the amino acids are broken down and return to the original state of the saliva, in the process white foam is produced.

In addition to white foam, some nest friends will also notice that sometimes bird's nest stews and turns into water, simply put, bird's nest is composed of water-soluble proteins, which will melt after being heated for a certain period of time. Of course, the following factors will also affect the state of the bird's nest during the stewing process:

1. Raw materials for bird's nest.

The old swallow silk is thick and not easy to stew. The fresh and tender nest bird's nest is smooth and relatively soft, so the simmering time must be well controlled.

2. Soaking and simmering time.

Rainforest house bird's nest is freshly picked in time, the soaking time of room temperature water is about one hour, simmering, simmering for 30-40 minutes in water, soaking and stewing time should not be too long, the swallow silk will soften after a long time. At the same time, when simmering in water, pay attention to the temperature in the cup should not exceed 80 to avoid the loss of effective active factors of bird's nest. If the water level outside the cup is too low, the temperature inside the pot will be too high, and the bird's nest will melt easily.

3. Reasons for matching ingredients.

Rock sugar bird's nest is a traditional way to eat bird's nest, and it is also the favorite of all nest friends. However, rock sugar should not be stewed in the same cup as bird's nest, because rock sugar has the effect of catalyzing food, and chefs are used to putting some rock sugar when cooking some hard-to-drench foods (such as abalone and beef brisket), so you should add rock sugar when the bird's nest is stewed and eaten.

Some non-natural inferior bird's nests, after chemical oxidation, the bird's nest is corroded, which will also affect the stewing. First of all, choose a good bird's nest, and then pay attention to the skills, so that there will be no water dissolution.

Finally, I would like to remind my nest friends that the stewed bird's nest should not be kept warm in the thermos pot for a long time, because the residual temperature will also make the bird's nest turn into water, and the rock sugar is best to warm the residual temperature!

The foam of bird's nest is slightly more complex when heated, and the main ingredient of its foaming is also protein.

Other ingredients in bird's nest will also appear in the foam, along with some impurities, which are best skimmed off. If the white foam is produced afterwards, mainly the protein of the bird's nest, it can be retained.

Bird's nest cannot be stewed until it is completely soaked for the following reasons:

2. After fully soaking, the bird's nest has fully absorbed water and is easier to stew, otherwise the bird's nest will be stewed at high temperature for a long time, but the water-soluble protein of the bird's nest will be lost if it is stewed at high temperature for more than 30 minutes, so it is very necessary to soak it.

Generally, bird's nest can be eaten after soaking for a long time, as long as there is no peculiar smell or turn green, it is harmless to the human body after eating, but it will affect the taste of bird's nest, and some of the nutrients in it will be lost.
