Do you wonder how to process an edible birdnest? If you have question of knowing the procedure, congratulation to you for your awareness in what you eat.
Practically, birdnest divided into two type;cave nest and house nest.
Cave nests are those nests harvested from the cave within a certain time frame(twice in a year or so), and house nest harvested in the bird premises are periodically(two week once and so on).
What is it so particular about harvesting time?
1. They are a lot of insects and microbes presented in the caves that contaminate the nest.
2. Some cave with rich minerals like iron will oxidised birdest with the present of humidity. The most common phenomenon is to turn the nest into red colour, that is what people used to name them as "blood nest". It fetch high price in the market due to legendary story of it. But would you like to have one in your stomach?(some unwanted ferrous oxide and minerals that is toxic).
So, is the house nest safe?
Yes, if you are a knowledgeable farmer.
Don't ever try to spray insecticide into your "food grade" farm. Insecticide contains mercury and lead, if you apply them into your farm , you are probably induce heavy metals to contaminated your nests.
The best solution now is to clean the farm regularly and applying beneficial microorganism .You may logon to http://www.em2enzyme.com for detail.
