I don't know if you are talking about thousand sheets or soybean oil skin. Every place calls him differently. Here are the general ways and ingredients for both:

1. Thousand sheets are made from soybeans. The soybeans are first ground into soymilk, then the soymilk is heated and boiled to make tofu brains, which are then pressed into thin slices using a mold. Thousand sheets are rich in protein, unsaturated fatty acids, lecithin, vitamins, calcium, iron, zinc, magnesium and other minerals, nutrients are very rich, can be supplemented with a variety of nutrients for the human body; thousands of sheets contain soy lecithin, which can promote the growth and development of the brain, to play the brain and brain, the effect of physical fitness; but also contains unsaturated fatty acids, which can lower blood lipids, lower cholesterol, to prevent hardening of the arteries and prevent cardiovascular disease; rich in calcium, can promote the growth of human bones and teeth, to prevent osteoporosis; contains iron and flavonoids, can play a blood nourishing effect.

2. Soybean oil skin is a natural oil film formed on the surface of the soybean milk after boiling, picked up and hung to dry. Chinese medicine theory that it is flat and sweet, with heat and lungs, cough and phlegm and stomach, detoxification and other effects. Soybean oil skin is rich in nutrients, protein, amino acid content, and easy to digest, good absorption, is a kind of old and young people are suitable for food, can be cold, shabu-shabu hot pot, for soup and so on. There is a famous product in Hangzhou cuisine - "dry-fried ringing bells", which is deep-fried with soybean oil skin, and after oil, it becomes golden in color and thin as a cicada wing, crispy in the mouth and sound like ringing bells, and the fragrance of soybean lingers in the throat, so it is named, and the eaters are all very happy with it.

Soybean oil skin production process is not complex. First soybean black beans and other ground into soybean milk, slow simmering fire, do not make it boil. Soon, the surface of the slurry will form a layer of oil film, which is the soybean oil skin. Reach a certain thickness, first with a knife along the four walls of the container gently scratched a circle, with a thin bamboo stick from the center gently inserted into the bean skin below, slowly pick up, ride to the drying rack to dry. After a short time, the surface of the soybean milk again to form a new soybean oil skin, you can pick up a piece.
