摘要： A method and apparatus for determining the contents of salt and water in a water-in-oil type emulsified product are disclosed herein. In the method, two kinds of physical quantities which are related to the contents of water and salt in the water-in-oil type emulsified product and are capable of being measured in a short time are measured. Then, values of the contents of water and salt are calculated from the two physical quantities measured, by use of a bivariable multiple regression equation wherein the two physical quantities are used as explanatory variables and the contents of salt and water are used as objective variables.
