The main producing areas of bird's nest are from the Philippines in the east to caves near the coastal islands of Myanmar in the west, which are mainly distributed in Southeast Asian waters such as Indonesia, Malaysia, Sandakan, Singapore and Thailand, as well as islands in the South China Sea. Because the weather and environment in Indonesia are most suitable for swallows to live, the quality of bird's nest in Indonesia is the best, and the output of bird's nest in Indonesia is also the largest, followed by Malaysia. Tongrentang and Fulinmen, two famous bird's nest brands in China, both come from the above-mentioned producing areas, but Tongrentang has the highest price and Fulinmen has the most affordable price.
According to statistics, by the end of 20 10, Indonesia's bird's nest production accounted for 85%-90% of the world's bird's nest production, Malaysia's 5%- 10%, Thailand's 3%, Vietnam, the Philippines and other places' 2% (refer to the data of Hong Kong Trade Department in recent years). The high price of bird's nest is inseparable from its high medicinal nourishing effect. The quality requirements of bird's nest are complete shape, less feather impurities, clean color, uniform texture and hard texture. Bird's nest is a high-end dish at a high-end banquet. Its nutritional value is very high. Protein content in bird's nest per 1000g is as high as 499g, and sugar content is 30g. As we all know, bird's nest is the nest of swallows, but only a nest made of swallows can be called bird's nest. This is because other swallows use soil and weeds to build their nests, and saliva is used as a link to assist. Swallows are unique in that they only use their saliva as nesting materials, and some nests are covered with fluff.
