Preparation method of lotus root starch:

Ingredients: peeled lotus root 500g, water 500-800g?

1, two lotus roots, one catty of lotus roots in 9 yuan, bought two lotus roots at 1 1 yuan. Generally, red lotus root is selected, and the starch content is higher than that of white lotus root. If the lotus root is short, thick and small in color, the flour yield will reach 10%.

2500 grams after peeling.

4. Put it into a cooking machine and add 500 grams of water.

5. Stir until it is very delicate.

6. Screen or use double gauze to separate slag, preferably double gauze to separate slag. If there is no double gauze, use a sieve of 40 to 60 meshes, and some people use a sieve of 20 meshes, but the finished product of 20 meshes should be rough.

7. After filtering out the lotus root residue, you will get a big bowl of water. Let this bowl of water settle for 3 to 4 hours, and the first stage of work will be completed.

14, then put the powder on a plate or directly on a baking tray with silicone oil paper, and continue baking at low temperature until the fermentation temperature (35 to 38 degrees) is dry.
