Abstract: The invention discloses a rapid detection system and a rapid detection method for a sericin content in silk, and particularly relates to a rapid detection method of the weight content of the sericin in silk. The detection method comprises 1. a step of establishing a standard thermogravimetric characteristics database of pure sericin and pure fibroin; 2. a step of determining a characteristic thermogravimetric curve of the silk to be detected at a specific temperature rising rate in a specific temperature range; 3. a step of standardizing the measured curve; 4. a step of mapping by utilization of the thermogravimetric curves to obtain a weight loss correlation graph of the sericin, the fibroin and the detected silk in a specific temperature range; 5. a step of forming two independent areas by the three curves and defining the two independent areas to be area 1 (formed by the thermogravimetric curve of the pure sericin and the thermogravimetric curve of the detected silk) and area 2 (formed by the thermogravimetric curve of the detected silk and the thermogravimetric curve of the pure fibroin); 6. a step of respectively calculating the area of each area, and calculating the ratio of the area of the area 1 to the total area (equal to the sum of the area of the area 1 and the area of the area 2); 7. a step of calculating the sericin content KTG of the detected silk accordingly; and 8. a step of converting into the sericin content in the standard environment according to need.
