It varies from person to person, and it can be hundreds or tens of thousands. The most important thing is to see what kind of people you meet. No matter how much money you have, you must understand that the most expensive tuition is definitely not the best. In fact, as far as cold noodles are concerned, it is actually very simple, at least not as complicated as everyone thinks. Bean jelly is a kind of pure starch food, which is made of starch in wheat flour. From the perspective of bean jelly, flour is composed of gluten and starch, so to make bean jelly, starch should be separated from flour first, and the way to separate starch is to wash your face, which is why you should wash your face when making bean jelly. After washing your face, flour is divided into two parts, namely gluten and starch. White material in the flour water is starch, and the gluten left in the basin is gluten. The freshly washed noodle water can't be used to make cold noodles immediately, mainly because the noodle water is too thin and the cold noodles can't be formed. In short, there are not many production processes of cold rice noodles, and as producers, especially novice friends, the most important thing is to understand the functions and purposes of each process in the production of cold rice noodles, so as to be targeted in the whole process. Inevitably, the main purpose of washing face is to separate gluten and starch, the main purpose of precipitation is to separate excess water from the surface water and increase the consistency of batter to meet the requirements of making cold noodles, and the main purpose of pulp mixing is to adjust the density and balance the pH value of batter, because in the process of precipitation, batter is a process of gradual fermentation and acidification, and it must be restored to its original state before it can be made. In a word, the most important thing to make cold rice noodles is the correct method, which is the basis for the success of cold rice noodles. Otherwise, you can't make a good product by hearsay alone.
