You should note that the accuracy of flour and gluten are different concepts. Accuracy refers to the fineness of processing. The higher the precision, the purer the flour and the better the quality. Gluten refers to the protein content in flour, which is generally divided into high gluten flour, medium gluten flour and low gluten flour. Simply put, it is also super flour. Because the wheat used is different, there will be different gluten, which is suitable for making different foods. Generally, cakes are made of medium gluten flour or low gluten flour.
