Research progress of factors affecting the determination of the inner quality of agricultural products by near infrared reflectance spectroscopy

Yu Haiyan,Ying Yibin~※,Liu Yande(College of Biosystems Engineering and Food Science,Zhejiang University,Hangzhou 310029,China)  
Near infrared spectroscopy analysis of the inner quality of agricultural products was a rapid and(accurate) technique.The effects of sample handling,chemical analysis as well as data processing methods were(investigated) with regards to the performance of the near infrared spectroscopy technology in determination of(inner) quality of agricultural products.The analyzed parameters were: 1)range of samples for calibration;(2)physical) and chemical properties of samples;3)errors relating to chemical analysis;4)fluctuations in apparatus and circumstances;5)pretreatment methods for NIR spectrum;6) chemometric methods for calibration and(validation) analysis.In order to obtain reliable results,it was advisable to take these variables into consideration when establishing NIR models for estimate the ingredients of agricultural products.
