    摘要: The invention discloses a NIR method for fatty acid content of oilseeds, including: selection of oilseed samples, and analyzing the oilseed samples by an near infrared spectrometer to obtain NIR spectra; preprocessing of NIR spectra and establishment of a NIR spectral database of oilseeds; establishment of a fatty acid database of oilseeds based on gas chromatography; establishment of prediction model of fatty acids in oilseeds; acquiring NIR spectrum of a sample to be tested by the near infrared spectrometer, and importing the preprocessed NIR spectrum into the prediction model of fatty acids to obtain the predicted fatty acid content of the tested sample. The method is simple and rapid to operate and is non-destructive, and the detection time of the sample is greatly shortened and the detection cost is reduced.

    摘要: An immunochromatography test strip for detecting pollution of diacetoxyscirpenol includes a bottom plate, where a water absorption pad, a detection pad, a gold-labeled pad and a sample pad are sequentially attached to one side of the bottom plate from top to bottom, adjacent pads are connected in an overlapping manner at a joint, the detection pad uses a nitrocellulose membrane as a base pad, a quality control line and a detection line are transversely arranged on the nitrocellulose membrane, the quality control line is coated with a rabbit antimouse polyclonal antibody, the detection line is located below the quality control line, and the detection line is coated with a diacetoxyscirpenol-ovalbumin conjugate; the gold-labeled pad is transversely spray-coated with a nanogold-labeled anti-diacetoxyscirpenol monoclonal antibody; and the anti-diacetoxyscirpenol monoclonal antibody is secreted by a hybridoma cell strain DAS5G11E7 with the preservation number of CCTCC NO.C201881.
