摘    要:随着转基因食品的推广应用,人们越来越关心其食用安全性。以转基因玉米及其亲本为实验材料,借助于近红外光谱仪对转基因玉米及其亲本进行了识别分析:扫描区间为12000~4000cm^-1,分辨率为4cm^-1,扫描次数为64次;以三层误差反向传播算法(简称BP算法)进行数据处理。结果显示通过扫描光谱及数学和计算机软件分析,非常准确、方便地识别了转基因农产品。所以通过近红外光谱所建立的转基因BP-网络识别模型完全可用于实际应用。近红外分析还具有无污染、成本低等优点,是一种极具前景的转基因食品安全检测识别技术。

关 键 词:近红外光谱  转基因食品安全  检测识别

Abstract:With the rapid development of the GMO, more and more GMO food has been pouring into the market. Much attention has been paid to GMO labeling under the controversy of GMO safety. Transgenic corns and their parents were scanned by continuous wave of near infrared diffuse reflectance spectroscopy range of 12 000-4 000 cm^- 1 ; the resolution was 4 cm^- 1 ; scanning was carried out for 64 times; BP algorithm was applied for data processing. The GMO food was easily resolved. Near-infrared diffuse reflectance spectroscopy is unpolluted and inexpensive compared with PCR and ELISA, so it is a very promising detection method for GMO food.
Keywords:Near-infrared spectrcscopy  Transgenic food safety  Detection and identification
