1. Bird's nest soaking in warm or cold water is effective. Bird's nests need to be soaked, cleaned and steamed before consumption, and soaking as the first step is very important. Throughout the soaking period of bird's nest, choosing the water is the most important step and the one that is most easily neglected. Here we mainly introduce two soaking methods, namely warm water soaking and cold water soaking.

2. Warm water soaking: Warm water here refers to pure water at room temperature, and you can't use tap water or mineral water because both are hard water. Experiments have shown that the expansion rate of bird's nest stewed in mineral water is 3 to 4 times, which is much lower than that of pure water (7 to 8 times), and it also affects the feeling of eating bird's nests that are soft and slippery, so for the sake of bird's nests' consumption, try to choose pure water. Before soaking, choose a container that can not exceed the bird's nest after adding water, put in the bird's nest, add the right amount of pure water, and soak it at room temperature. This method is the most commonly used and convenient method, which is more suitable for spring and fall, when the temperature is at 20~30℃.

3. Cold water soaking: Put an appropriate amount of pure water into the bird's nest and add ice cubes, and put it in the cold room of the refrigerator to soak. Compared to warm water soaking, cold water soaking takes longer time, so this method is not suitable for summer when the weather is hot, because the temperature is too high in summer, all kinds of microorganisms grow and multiply rapidly, soaking time is long and easy to deteriorate and spoil.

4. Bird's nest soaking time is not the longer the better, it has a lot to do with the species of bird's nest. Usually, Cave Bird's Nest needs to be soaked for 6-12 hours; Blood Bird's Nest needs to be soaked for 12-24 hours; White Bird's Nest needs to be soaked for 4-6 hours; Bird's Nest Silk Bird's Nest needs to be soaked for 2 hours; Bird's Nest Strips needs to be soaked for 6 hours; Bird's Nest Cake needs to be soaked for 4-6 hours; and when soaking bird's nests, don't use tap water, which is used for sterilization purposes and residual chlorine during processing. Long soaking time will cause the loss of bird's nest nutrients.

5, in addition, bird's nest and rock sugar, walnuts, jujube, cinnamon, goji berries, ginseng and other stewed with food, can be a safe and tonic, to promote the intellectual development of the fetus, have a beauty beauty, light spot spotting, whitening the skin, the effect of removing stretch marks.
