Abstract: Near infrared technology is one of nondestructive，rapid and green analysis technologies，and can be applied to the determination of oil and grease product as well as oil seeds quality by oil factories.The technology has brought huge economical benefits with factories.A novel domestic broadband（1 000~2 500 nm）analyzer based on near infrared reflectance spectroscopy performs well and possesses the outstanding software integrated with the functions of spectra acquisition，modeling，remote control and management.The analyzer was successfully used to determinate contents of the moisture，protein，fat and amino acids in the soybean and soybean meal.The results show that predicated values for near infrared method are correspondingly near to reference values for national standard methods and the near infrared domestic analyzer can meet the requirement of quality controls for oil and fat products as well as oil seeds.
