After being subjected to sorting, washing and drying at room temperature to evaporate moisture on the peel, and then the raw materials are allowed to react naturally for 30-90 days in an environment with a temperature of 45-90°C and a relative humidity of 50-95%; and when the total amount of ketosamines therein remains stable for 5 consecutive days, the reaction is stopped. The content of the ketosamine components in the product can be up to 1.0-50 mg/g (dry weight), an increase of 5-30 times the content of the ketosamine components that are naturally found in the raw materials or formed during a common food processing process.
