The structure and Sodium lactate
Wheat is one of China's large -scale cultivation of crops for a long time , a variety of pasta made from wheat flour is preferred by the people of northern China 's staple food. However, the quality of wheat flour products affected species , origin, milling technology , Sodium lactate , the existence of mass fluctuations which are due to the composition of flour, starch , proteins, lipids , etc. , the ratio changes and quality caused by the change . And they often need to add some modifiers ( such as emulsifiers , antioxidants, enzymes , etc. ) to improve the quality and stability of the product and the production of pasta . CSL / SSL is the most widely used products in the face , the combined effect of the best emulsifier , it is often used as a "stabilizer" or " Insurance agent" in foreign mills to use, only the United States in 1996 reached 10 usage tons, the last year world demand rate of 6% --- 8% .
