Abstract:The origin of food has been concerned about the problem， some of the phenomenon of the manufac－ ture and sale of counterfeit food despite repeated prohibitions.In order to maintain the market order， protect the legitimate rights and interests of consumers， so the urgent need for food origin traceability for rapid non-destruc－ tive testing. At present， near infrared spectroscopy， mineral element fingerprinting， DNA fingerprinting， etc. are commonly used detection methods. Near Infrared Spectroscopy （NIR） is widely used in the study of trace－ ability of food origin because of its characteristics of high efficiency， fastness， no damage， no pollution and low cost detection. In this paper， the principle of near infrared spectroscopy was summarized， and the method and conclusion of its research on traceability of meat， fruit and grain were summarized. The near-infrared spec－ troscopy can be used in traceability detection of food origin. At the same time， the application of near-infrared spectroscopy in the origin of food origin had been analyzed， and the existing problems and future research trends in the origin of food origin were pointed out， which provided a theoretical reference for near - infrared spec－ troscopy in food traceability system analysis.
