Application of bacterium cellulose, potato vermicelli and preparation method of potato vermicelli

The invention provides application of bacterium cellulose, potato vermicelli and a preparation method of the potato vermicelli. The bacterium cellulose instead of alum is used for preparing the potato vermicelli, and the vermicelli breaking rate of the vermicelli can be effectively reduced; starch is screened, and pure potato starch is selected for making the vermicelli, so that the vermicelli breaking rate can be reduced to 0; when the bacterium cellulose of 0.12% is added, the vermicelli breaking rate is decreased to 80%; when the bacterium cellulose of 0.15% is added, the vermicelli breaking rate is 0. Because the bacterium cellulose cannot be absorbed by human bodies, the bacterium cellulose can be eaten for a long term, and the bacterium cellulose is discharged out of the bodies through intestinal tracts and is pollution-free to environment, so that the potato vermicelli is non-toxic and harmless to the human bodies and the environment, and meets or exceeds the quality requirements of the vermicelli produced in the prior art; besides, the preparation method is simple, and is suitable for the needs of large-scale industrial production.
