Hello, I am Science Xiaoquan, a creator in the field of science of Baijiahao. Today I would like to share with you an interesting and practical topic: how to choose bird's nest? Bird's nest is a precious tonic, which has the effects of beautifying the skin, moisturizing yin and dryness, and enhancing immunity, but the quality of bird's nest on the market is uneven, and some are even fake and shoddy, so how can we distinguish the real from the fake and choose high-quality bird's nest? Let me reveal the mystery of bird's nest for you!
Bird's nest is a nest made by swiftlets, a subspecies of swifts, with their own saliva and other substances, mainly found in some islands and caves in Southeast Asia. The main ingredient of bird's nest is siniary acid, a polysaccharide protein that contains a variety of amino acids, minerals and trace elements, and has good nutritional value for the human body. The shape of bird's nest is in the shape of a cup, a bar, a cake, etc., and the colors are white, yellow, red, etc., and different shapes and colors represent different qualities and values.
When choosing bird's nest, we should pay attention to the following aspects:
The degree of dryness is an important indicator of the quality of bird's nest, and the higher the degree of dryness, the easier it is to preserve and the less likely it is to spoil. Dried bird's nests are generally lighter, break when broken by hand, and have a crisp sound. Moist bird's nests will be heavier, not easy to break when bent by hand, and elastic. Moist bird's nests may not have been dried sufficiently, or they may have been artificially added to gain weight, so try to avoid buying them.
Texture is another important feature of bird's nest, the clearer the texture, the purer and more nutritious the bird's nest. A good bird's nest, whether it is a body or a capsule, should have a trace of fiber, and the thickness is different, and there is a sense of layering. If the texture of the bird's nest is very fuzzy, or very neat, or very dense, then it may have been artificially processed, such as brushing, pressing the bottom, sticking, etc., such bird's nest will not only affect the taste, but also reduce the nutritional value, and even harm to health.
Color is another important feature of bird's nest, the more natural the color, the more natural and safe the bird's nest. Generally speaking, the color of bird's nest should be transparent or yellowish, shiny, and have the fragrance of bird's nest. If the color of the bird's nest is very white, or very bright, or there are other colors, then it may have been bleached or dyed, which will not only destroy the nutrients of the bird's nest, but also leave harmful chemicals behind, which is harmful to the human body.
Weight is the last important characteristic of a bird's nest, and the lighter the weight, the drier and purer the bird's nest will be. Generally speaking, the weight of a bird's nest should be between 4-10 grams, if it exceeds this range, then it may be because the water content of the bird's nest is too high, or it has been artificially aggravated, such as brushing, sticking, etc., such bird's nest will not only affect the foaming effect, but also reduce the quality, or even fake.
Bird's nest is a precious tonic, but the quality of bird's nest on the market is uneven, and some are even fake and shoddy, so we must keep our eyes open when buying, pay attention to distinguish the real from the fake, and choose high-quality bird's nest. When choosing bird's nests, we should judge from the degree of dryness, texture, color, weight, etc., and choose those bird's nests that are dry, have a clear texture, natural color, and moderate weight, so that we can eat the real benefits of bird's nest, beautify and nourish the skin, moisturize and dry, enhance immunity, and make our bodies healthier and more beautiful!
