Quantitative analysis of starch,amylose and amylopectin in sorghum seeds by Fourier transform near infrared spectroscopy
摘要
Abstract
The content of starch,especially amylopectin,in sorghum seeds are extremely important to the quality of Moutai -flavor liquor which was fermented from sorghum,yet the research on determination for starch,amylose and amylopectin is paid great attention.Fourier transformed near infrared spectroscopy (FT -NIRS),due to its accuracy,stability,quickness and non -destructiveness,was successfully ap-plied to setup a simultaneous determination system of starch,amylose and amylopectin.The results showed that the correlation coefficients of starch,amylose and amylopectin quantitative models were 0.954 9、0.923 6 and 0.940 1,while the root mean square errors of cross validation were 1.027 1、0.088 5 and 1.264 6.Thus it was concluded that FT -NIR is absolutely appropriate for the analysis job.关键词
