柠檬酸盐在牛奶和奶粉中的作用,看起来具有多种功能,可以把它看作钙离子的螯合剂。因此,柠檬酸盐既影响牛奶蛋白的热稳定性,又影响牛奶蛋白的粘稠度。为了保证牛奶或奶粉的质量,测定柠檬酸是一个重要的内容。本法改进了光度法测 The role of citrate in milk and milk powder appears to have multiple functions that can be thought of as chelating agents for calcium ions. Therefore, citrate not only affects the thermal stability of milk protein, but also affects the viscosity of milk protein. In order to ensure the quality of milk or milk powder, determination of citric acid is an important content. This Law improves the photometric method
