Rice flour refers to strip and filiform rice products made of rice by soaking, cooking and layering, rather than powdered materials made of rice by grinding.

Rice noodles are rice products, also known as rice noodles, which are cooked rice and ground into powder, and then made into strips through layering and other processes. Therefore, rice noodles are very tough and elastic, and there will be no soup paste when cooked in water for a long time, and the taste is very smooth.

After being opened, rice noodles can only be stored at room temperature for about 1 month, because the sealing will be oxidized when it comes into contact with air, resulting in the loss of nutrients in rice noodles, and may adhere to the surface of rice noodles when the air humidity is high, leading to mildew and deterioration.

There are many kinds of rice noodles, which can be divided into row rice noodles, cube rice noodles, corrugated rice noodles, silver rice noodles, wet rice noodles and dry rice noodles. Their production processes are similar, generally: rice-elutriation-soaking-pulping-steaming powder-tabletting (shredding)-re-steaming-cooling-drying-packaging-finished products.
