Different Types Of Bird’s Nest
Cave Nest Vs House Nest
In the case of Cave Nest, where the bird’s nest is harvested from natural cave, the bird’s nest is exposed to fairly high humidity and impurities relative to the House Nest. It is evident that the House Nest in a controlled environment where you can find workers clearing the bird’s nest is much cleaner than the Cave Nest which is exposed in the wild environment.
Natural Bird’s Nest Vs Chemically Treated Bird’s Nest
Natural Bird’s Nest (Translucent yellowish white bird’s nest) is harvested from purpose-built swiftlet house. It is cleaned manually without any use of harmful chemical, while chemically treated bird’s nest is processed utilising cleaning agents (such as bleaching agent) in mass production.
Bird’s Nest Biscuit
Bird’s Nest Biscuit is regarded as a low quality (unwanted) bird’s nest, which man makes into the shape of a biscuit. These “biscuits” are put together from bits and pieces of the broken bird’s nest, held firmly together in a mold and left to dry. It does not usually expand much after soaking in water and the nest most likely falls apart after soaking in water for an about an hour.
