The items for making fake snow swallows are as follows:

1. Totally fake bird's nest made from pigskin

Pigskin swells into small pieces after frying, and egg white imitates the smell of eggs. After mixing evenly, drying to form loose pieces, particles, etc. This kind of material is generally used to make swallows or swallow cakes. The surface of the finished product made of pigskin is light yellow, slightly transparent and shiny.

The disadvantage of pigskin fake bird's nest is that it will break when pulled, and it is not elastic. It is easy to tell whether it is loose or not after soaking, and it has a greasy taste after a long time. Bird's nest can be used or burned. When pigskin is made, there will be sparks, black smoke, burnt smell and black ash.

second, make fake bird's nest with tremella fuciformis as raw material.

Tremella fuciformis is dried and made into fine particles, and egg whites are evenly mixed to make dried products. The shape is scattered, broken into irregular pieces, light yellow or yellow and white in color, slightly transparent and shiny. This kind of fake bird's nest expands quickly after entering the water, but it is not elastic when rolled by hand and has no taste of natural bird's nest.

Third, fake bird's nest made of seaweed brush glue.

what a surprise! Seaweed and fish skin can also be used to make fake bird's nest, and the technology is good enough to confuse the fake with the real. This kind of bird's nest can be recognized immediately by the foam or entrance, and its taste is extremely poor. There is nothing like bird's nest.

Fourth, the fake bird's nest made of gum-Xueyan.

I believe everyone has heard that the snow swallow is made of gum, because it is not easy to be impurity-free, because the labor cost is high, and the snow swallow is hard when you pinch it, so it is easy to tell. However, if the snow swallow is soaked in egg white, it can be genuine. If it is made into freshly stewed bird's nest, it is difficult to judge, which is enough to make it genuine.

5. Fake bird's nest made of bean flour or starch (usually processed into strips of swallows)

The imitation bird's nest made of bean flour is a long and irregular block. The surface of fake bird's nest processed with soybean powder is brown and has unnatural luster. The surface of the fake bird's nest made of starch is yellow-white or beige, with rough surface, horny appearance and net inside. After soaking, it will swell slightly and is not gelatinous.
