How to identify genuine bird’ s nest?
Bird’s nest is an expensive and nutritious product. Thus, it is
important to know how to distinguish a genuine piece of bird’s
nest. In the market, there are many unethical businessmen who
would increase the weight of bird’s nest by adding additives like
white fungus, jelly and animal skin. No two pieces of bird’s nests
will be exactly identical in shape or size since bird’s nests are
produced naturally by swiftlets. Genuine and pure bird’s nest
should have been thoroughly cleaned without the use of any
chemicals, colouring or preservatives.
Authentic and pure bird’s nest should exhibit the following
Cleaned bird’s nest should still be offwhite
or ivory with subtle and natural
variations in shade, rather than a
consistent white colour throughout
which is indicative of bleaching
techniques being used.
Appearance & Texture
The outer part of the nest consists of
longer, bigger filaments whereas the
inner part has finer, shorter filaments.
Cleaned bird’s nest should also be
properly dried until filaments and
strands become quite fragile and break
off easily. This ensures maximum
value per gram and prevents microbial
growth and natural formation of
Authentic and pure bird’s nests are
able to absorb water up to at least 8
times its own weight. In particular,
the longer and bigger filaments on the
outer part will expand significantly
after soaking in water for 30 minutes.
A faint scent of albumin (egg-white)
smell will also start to emanate.
After double-boiling for approximately
1 hour, the smaller filaments would
have dissolved into the water, whilst
the less-soluble bigger filaments will
give bird’s nest its signature fibrous
taste and appearance.
