Bird's nest you buy should be stored airtight, away from sunlight and air. Even so, there are cases where bird's nest changes color. Most typically, a white bird's nest develops light yellow spots, dark yellow spots, or even turns orange. So why does bird's nest turn yellow?
Causes of bird's nest turning yellow
Normally, white swiftlet nest is ivory white to slightly yellow. However, if some time after you buy it your bird's nest suddenly develops light yellow spots, dark yellow spots or an orange color, there is a risk that you bought bird's nest mixed with impurities. These impurities may be starch, sugar, or egg white,… They are added to increase the weight of the nest. After a while these impurities oxidize, causing the nest to change color. Poor-quality bird's nest that is kept longer will oxidize more severely. The color of the nest gets darker, from light yellow to deep orange. Even worse, if it is oxidized too badly, the nest strands will loosen and no longer hold together tightly as they did at first.
Bird's nest changing color – a risk of counterfeit or poor-quality goods
If the bird's nest you bought changes color some time later and also shows some of the signs below, you can be 99% sure that the bird's nest is counterfeit or mixed with impurities.
The bird's nest smells pungent and unpleasant: egg white, starch and refined sugar are commonly used to bulk up bird's nest. The purpose is to increase the weight of the nest. When these added substances oxidize, they produce a very unpleasant fishy smell.
When soaked in water, the bird's nest changes color.
The bird's nest partly or completely dissolves when steamed.
The nest strands are soft and pliable. When squeezed, the strands are not brittle but slightly moist.

How to store bird's nest properly so it does not lose its nutrients
Storing raw bird's nest
To store whole raw bird's nest, keep it in a dry place. Do not keep it in a place that is too airtight or damp, as moisture will spoil the nest. Do not place it where light shines on it either, because sunlight can destroy the structure and nutritional content of the nest.
Storing raw bird's nest is considered the simplest compared with other types of bird's nest.
Storing bird's nest after cleaning
After being cleaned, bird's nest should be drained; then put it in boxes with tight lids and place it in the refrigerator's cooler compartment. With this method, you can use it within a maximum of 1 week.
If you want to store it for longer than 1 week, after cleaning and draining, wrap the bird's nest in foil and keep it in the freezer compartment.
Tips for storing cleaned bird's nest for many months
If you want to store cleaned bird's nest for a longer time, you need to dry it. You can use drying at a moderate temperature. Note: never dry the nest directly under the sun or in an oven or microwave at high temperature, because that will make the nest lose its nutrients.
After drying it thoroughly, put the bird's nest in a clean plastic bag, vacuum-seal it and keep it in a dry, cool place to use gradually. This method lets the bird's nest be used for a longer time, but it is still best not to keep it too long.
Notes when storing bird's nest
– When bird's nest gets damp it becomes soft and dust sticks to it easily. To fix this, you can use a clean, soft-bristled toothbrush to brush it gently, clean it, dry it, and store it following the steps above.
– Never use bird's nest that has turned black. That nest has been eaten away by bacteria and is very harmful to health.
