Method for extracting grease in sauce and measuring fat content, peroxide value and acid value at same time

The invention belongs to the technical field of food, and discloses a method for extracting grease in sauce and measuring fat content, peroxide value and acid value at the same time. The method is simple to operate and simple in instrument; the test time period is short and the efficiency is high; the method is suitable for oil extraction of the oil-rich emulsified and embedded sauce (salad sauce), the extraction rate is high, the peroxide value and the acid value are tested, the result is not interfered by a pretreatment method and is more representative, and the problems that the oil in the oil-rich emulsified and embedded sauce is not easy to separate and extract and the peroxide value and the acid value are greatly influenced by acid hydrolysis and alkaline hydrolysis methods are solved. The system can simultaneously monitor three physicochemical indexes of fat content, peroxide value and acid value at one time, is high in efficiency, is more suitable for tracking and monitoring in the production process
