Dynasty Nest strives to provide our customers with the latest news regarding bird’s nest. We will also share the exciting scientific findings on edible bird’s nest and how it has made an impact on the development of bird’s nest based products. We hope that by reading this, our customers will achieve a further enhanced confidence in purchasing Dynasty Nest products.

The myth-busting truth about health benefits of bird’s nest. Is it scientifically proven ?

Bird’s nest has long been regarded as a nutritional food among the Chinese community all around the world. Little research has been done to further understand the nutritional benefits of bird’s nest from a scientific point of view. With the advancement of science and analytical tools, it is now possible to explain the health benefits of bird’s nest. Dynasty Nest aims to provide our consumers with the latest scientific update on edible bird’s nest as part of our ongoing research and development.

The health benefits of bird’s nest all come down to what bird’s nest is really made up of. What are the main active ingredients in bird’s nest?
  1. Amino acids and proteins. Proteins make up about 60% of the bird’s nest.
  2. Growth factors. There are at least 7 growth factors in bird’s nest including epidermal growth factor, testosterone, estradiol, progesterone, luteinizing hormone, follicle-stimulating hormone and prolactin. These growth factors promote cells repair and regeneration, hence contributing to the rejuvenating effect of bird’s nest.
  3. Minerals. Bird’s nest is rich in calcium, magnesium, potassium and iron. The level of minerals in bird’s nest also determines the level of fermentation and oxidation which results in the various colours of bird’s nest. White bird’s nest is rich in calcium whereas the red bird’s nest is richer in iron which explains the reddish colour.
  4. Sialic acid is responsible for the anti-influenza virus activity.
  5. Chondroitin glycosaminoglycans which are the most important component in bone and dermal.

The role of birdnest extract in bone improvement and dermal thickness.

A recent article published by a group of Japanese researchers looked at the effect of feeding bird’s nest to menopause rats.

  1. Menopause women lack the ovarian hormone, which can induce osteoporosis.
  2. Current therapeutic approach to prevent postmenopausal osteoporosis is hormone replacement therapy. This, however, increases the risk of breast and uterine cancers.
Summary of findings:
  1. Bone strength increases significantly in menopause rats receiving the bird’s nest extract.
  2. Collagen thickness i.e. skin thickness is significantly higher in menopause rats receiving the bird’s nest extract.
  3. Calcium and phosphorus contents in the bones are also significantly higher in menopause rats receiving the bird’s nest extract.
  4. The above findings can be attributed to:
    - the mineral contents in edible bird’s nest, such as calcium and phosphorus,
    - the chondroitin glycosaminoglycans, which is one of the main components of the bone.
  5. Edible bird’s nest may offer a safe alternative treatment to menopause induced osteoporosis, without the risk of cancers.

Different types of bird’s nest

What are the different types of bird’s nest? How are they graded?

Bird’s nest is typically graded according to their source, their colours and size as summarised in Figure 1.

Figure 1. The grading systems of edible bird’s nest.

Bird’s nest can either come from cave or manmade swiftlet houses. Cave nests usually come with a dearer price tag and in our opinion, an unjustified one. The hefty price tags of cave nests are mainly due to the dangerous nature of nest collection in the cave. Such dangerous act prompts the harvesters to collect every nest even if there are some swiftlets nesting in it, leading to a non-sustainable and unethical harvesting method.
Figure 2. Unprocessed bird’s nest coming from manmade houses.

The bird’s nests produced in the cave or in the manmade swiftlet houses are produced by the same species and both are produced naturally. The houses merely provide a shelter for the swiftlets whose natural habitat has made way to urbanisation. Bird’s nest farmers do not control what the swiftlets eat. Furthermore, the swiftlet houses provide a much cleaner breeding environment which results in much cleaner nests compared to those in the cave. The much dirtier cave nests also require chemicals during cleaning process. Not only this can damage the nutrients in the nest, consumption of such chemicals might be harmful to our body. 

The different colours of bird’s nest (Figure 3) is a result of fermentation and oxidation process of the minerals content. When bird’s nest is originally formed, they are white in colour. It is thus fair to say that white nest is the purest form of bird’s nest. Depending on the environment of the bird’s nest house, the nest will absorb moisture and minerals which can undergo fermentation and oxidation. Due to the rarity of the red nests, they are much more expensive. This has led to the fabrication of fake red nests in the market. These nests are tainted with colouring or unnatural fermentation process which lead to very high nitrite levels in the nests. Such high nitrite levels are harmful to the body when consumed in the long term.
Figure 3. The different colours of bird’s nest in the market.

Being a natural product, bird’s nest come in various sizes as illustrated in Figure 4. The larger the nest, the more expensive it costs. The smaller nest is usually formed in the corner of the house.

KL producers unhappy as Beijing clips their wings


For the past one year, China has banned the imports of bird’s nest from Malaysia after it found more than 200 ppm of nitrite levels in the country’s bird’s nest samples. This nitrite level is much more than the permissible level set out by the World Health Organisations (WHO), which is less than 34 ppm. Being the world’s largest bird’s nest consumer, such ban has led to the oversupply of bird’s nest to other consumer countries such as U.S.A, Singapore and Canada. Combined with the reduced consumer’s confidence for fear of consuming the tainted bird’s nest, this oversupply has led to a 30% reduction in the bird’s nest prices.

Our quality assurances to our customers:

By using no chemicals in our cleaning process, we preserve the nutritional value of each nest. Furthermore, this has led to the consistently low nitrite levels in Dynasty Nest products. Agri-Food & Veterinary Authority (AVA) report number V-021-2012-01-00127, dated 6 February 2012, revealed a less than 10 ppm of nitrite levels in our bird’s nest sample. This is much lower than the permissible level set out by WHO as well as the Singapore standards. Bird’s nest is categorised under processed food in Singapore laws and the permissible nitrite levels is lower than 125 ppm (Singapore Food Legislation Fourth Schedule).

We only supply genuine bird’s nest to our customers and being a direct supplier and importer, we know where each nest comes from and how it is produced.
