Scientific method of cleaning raw edible birdnest

To many,to learn how to process raw uncleaned birdnest is utmost important.

To ignore the science of cleaning will bring disaster...

How?

If edible bird nest(EBN) is to consider health food, any good evidence shown that the food is safe?

We normally based on judgement by looking at the appearance; if red or yellow color, then it must be expensive. If it looks big and white, then it considered good. Do you believe?

A few tips to consider for pureness of EBN.
1. Do they come from control environment? Cave nests were from the nature cave, may have contaminate by insects or bacterias . House nests were to consider control food source providing practicing good animal husbandry practice. Do have found results of house EBN with heavy metals and toxic chemical. Spraying of insecticide will result EBN contaminated with mercury,lead,arsenic,cadmium,ferrous,sodium nitrite and others. If raw EBN were from contaminated environment, then the processed cleaned birdnest may not cleaned at all.

2. Do consider get raw materials EBN from known source. A few occasions were detected house EBN contained heavy lead from wall painted with paint. Some nests were possible contaminated with sulphide from the rotten eggs. Worse to announce that some killer bacterias were detected from nest with dead chicks.

3. Another source of contamination is from ammonia gas emitted from birds' droppings. Ammonia gas not only will resulted sodium nitrite formed but it damaged human lungs too.

4. Is tap water considered safe? The answer is NO. Many molds and fungus formed were the cause of bacterias from water. Too long the soaking time too, will provide room for bacterias to emulate.

5. Cleaning room is very important to deter bacterias from cross contamination. A system; ISO 22000 is an assurance for good quality EBN .
