Introduction to Edible Bird’s Nest (EBN)

Edible Bird's Nest IntroductionEdible bird’s nest (EBN) is one of the commonly use health-modulating foods in Chinese populations. In traditional Chinese medicine, EBN is known for its beneficial effects in treating several ailments including consumptive disease, tuberculosis, asthma, dry coughs, stomach ulcers, gastric troubles and bronchial disorders. Due to food and medicinal values, EBN is quite an expensive animal bioproduct, and has thus created lucrative industry in Southeast Asia. It is one of the main contributors of gross domestic product in several Southeast Asian Countries like Indonesia, Malaysia, Philippines and others.

EBN is the dried saliva of swallows / swiftlets commonly found in the Southeaast Asian Countries e.g. Indonesia, Malaysia, Philippines, Thailand and Vietnamese. Swiftlets are tiny insectivorous birds that often keep on catching insects during flight from nearly first light until dark. Amongst the several swiftlet species in Collocalia genus, only the nests producted by Collocalia fuciphaga, Collocalia germannis, Collocalia maxima and Collocalia unicolor are commercially important due to their human consumptions.

Edible bird’s nest (EBN) is called differently in different languages e.g. Yan Wo in Chinese, Sarang Wallet in Indonesian and Enso in Japanese. The saliva secreted from the sublingual salivary glands of swiftlets during nesting and breeding season is the main material used in building of the nests. Generally, the sublingual salivary glands of swiftlets increase in weight from 2.5 to 160mg, and reach their maximum secretory activity during nesting and breeding season. Nests are built using saliva as a cementing material for binding feathers and other vegetation together. It also ensures firm attachment to the vertical walls of inland or seaside caves.

Grading of EBN

The grading of EBNs is measured on account of their dry mass, the time spent by swiftlets in building nest, and finally the fat and protein content of hardened saliva. As an example, the white nests are almost entirely made from saliva, while the black ones are composed of almost 45-55% feathers and small dried leaves.

The bowl shaped EBN is the most popular one in the market compare to other shapes e.g. triangle (corner nest), broken pieces, etc.
