The understanding of edible-birdnest starts from the hairy bird's nest, which is the most primitive way of picking the bird's nest in the swiftlet house. We can often see that there are roof beams built inside the swiftlet house, this is to create more nesting places for the swiftlets, and the roof beams are made of various materials, such as wood, lime, foam, etc. The base of the bird's nest can be trimmed to fit the wall or the crossbeam. As the base of the nests are close to the walls or beams of the swiftlet houses, they will also be removed together during the harvesting process, so it is inevitable that wood dust, foam, iron mesh white ash, etc. will stick to the nests during the harvesting process.

What is the base of a swiftlet? The base is where the bird's nest meets the stone wall or wooden board, which is equivalent to the "foundation" of the swiftlet's home and holds the bird's nest in place. Some nests are thicker, some are thinner, and the nests just picked will have some wood chips and foam on the nests. The factories will carry out simple chipping before picking the hairs to remove the impurities such as wood shavings, wall plaster and foam from the base before picking the hairs, of which the foam is the most difficult to clean.

The base of the bird's nest is the part that hides the dirt, while the cleanliness of the raw materials of the bird's nest is different, and the different techniques of the hair picking factories are different, so the base of the bird's nest will be different.

Bottom trimming before picking:

The picture shows a dry picking jian with the base trimmed, the body of the jian looks thin and natural, and the base looks fluffy when pressed, with natural gaps. If the base is broken, there will be a hard feeling when pressed, and it will look very regular, dense and without gaps, and the texture of the bird's nest will not be clear and natural. Good bird's nest, is to be the more natural the better, the base of the fiber, in general, are to be natural, thin, no sticky broken for the best, otherwise the pro is to use the money of swallow marigolds to buy the quality of swallow broken.

In terms of the base, our factory pursues to stick to the natural original marjoram as much as possible, as long as the raw material is clean enough and there is no need to dismantle the base, we will try our best to retain the original state of the base, usually with a slight trimming. The factory trims the base to make the calendula shape more beautiful, but also maximizes the retention of the calendula body meat, so that we can soak it up more easily, and eat all the bird's nest, better taste, and more affordable and cost-effective compared to eating the edges of the cut off material.
