近红外技术对南疆冬枣糖度无损检测的研究
Research on the Non-destructive Testing Technology of Near-infrared in Sugar Content of Dongzao Jujube in South of Xinjiang
摘要
Abstract
The aim of the study was to establish model for predicting sugar concentration of Nanjang Hetian Dongzao ju -jubes .One hundred Hetian Dongzao jujubes were assigned to establish model of jujubes .The sugar degree of jujubes were quantitatively determined by Near Infrared Spectroscopy ( NIRS ) , spectroscopy pretreatment methods were multipli-cation scatter correction (MSC), first derivative , Svitzky-Golay (S-G) and Normalization , the results showed that the best effect of the calibration model of saccharinity within the spectral region of 5303-5600cm-1 ,6205-6302cm-1 and 7308-7405 cm-1 which selected through the method of correlation respectively , the model was established by Partial Least Squares, and SEC and SEP are 0.613 and 0.573, respectively, calibration coefficient and prediction correlation coeffi-cient are 0.967 and 0.965, respectively.The final results indicated that the model is an effective method to rapid detect sugar degree .关键词
