4hw.org: Bird's nest is a kind of very expensive food. Its nutritional value and scarcity cause its price to be particularly expensive compared with other food materials. Many bird's nests on the market are fake and shoddy. Don't you know how to distinguish the true from the false? What are the nutritional values of bird's nest? Let's have a look!
1. We know that the origin of bird's nest is generally in Southeast Asia. Indonesia's bird's nest accounts for 80% of the world's total bird's nest production, Malaysia's 13%, Thailand's 5% and Vietnam's 2%. There are three Chinese bird's nest production places: Yanyan, HUAIJI County, Zhaoqing City, Guangdong Province, Yanzidong, Jianshui County, Honghe Prefecture, Yunnan Province, and Dazhou Island, Hainan Province (only two bird's nests were picked in 2002, only 15 golden swallows were left in September 2006, long-term island protection). As it is close to the Tropic of cancer, the bird's nest has strong seasonality, and its output is rare. The total output is less than one tenth of the global bird's nest output. Now the bird's nests on the market are all house swallows. Features: the house swallows in environmental protection are cleaner, smoother, whiter and more delicate than those in harsh environment. The white swallows we see now are all produced in the artificially built swallow house. Generally, it comes from Malaysia, Indonesia and other countries, and its Yanwu industry has become large-scale. No matter the culture technology or natural climate conditions of Yanwu, it is incomparable to other bird's nest producing areas. So the best bird's nest in China is produced in Malaysia.
2. The normal weight of a pure bird's nest is between 4 and 8 grams, and very few bird's nests have more than 10 grams. In recent years, in order to make higher profits, the bird's nest businesses on the market have carried out "glue brushing" and "weight increasing" treatment. The weight of a 4-gram triangular swallow can reach about 6-7g after glue brushing, and the weight of a top-level swallow can reach more than 12g after weight increasing treatment. However, the real bird's nest ingredients of these processed bird's nests are only half or even less! Therefore, these bad businesses can adjust the price to lower than the raw material price of the origin (according to the Indonesian Ministry of forestry Materials show that at present, the price of Indonesian bird's nest mainly has three levels, ranging from 20 to 30 yuan, and the profit is higher. Generally, regular businesses will provide trial food, such as brother bird's nest will have the opportunity of free trial food on site. In addition, water is also an important factor in the price of bird's nest. The main nutritional component of bird's nest is water-soluble protein, which is easy to absorb water. After some poor vendors take water treatment for bird's nest, the price of bird's nest is only ten yuan per gram, attracting consumers with low price.

2. In the process of bird's nest hair picking, bird's nest is a unique nest made of saliva by Golden Swallow in Southeast Asia. There are many fine hairs and impurities on the newly picked bird's nest. The normal treatment method is to spray water to wet the bird's nest, then tear the texture of the bird's nest with tweezers, and pick out the fine hairs and impurities. This process is the most time-consuming one. A few years of picking technician can only pick 6 to 7 pieces of bird's nest a day, so the time of picking each piece of bird's nest will increase correspondingly, and the cost will also increase.
3. The artificial bird's nest is treated with chemical depilation, which greatly reduces the labor cost: soaking with hydrogen peroxide to depilate. Pour a large number of bird's nests into the whole vat of liquid medicine, and let hydrogen peroxide remove all the fine hairs and impurities of bird's nests. The bird's nests made by this way have low cost, beautiful color, very clean, very white, even color, and very good selling appearance. But the hydrogen peroxide residue in the bird's nest is more than 1000 times of the safety standard. Eating it is very bad for the body!
