Alkaline water concentration is very important, the concentration of alkaline water is too low, resulting in the addition of a large amount of alkaline water, will reduce the amount of syrup in the dough, the moon cake dough will be "on the tendon", the product is not easy to return to the oil, back to the soft, and easy to deformation; alkaline water concentration is too high, will result in the surface of the moon cake coloring is too heavy, the alkalinity increases, the taste texture deterioration.
