The crude protein(CP) content is an important index to evaluate the quality of fish feed. Near infrared spectroscopy (NIRS) is often applied when a rapid quantization of CP content in feed is required. 240 samples of 4 fish feed brands (Takara sakana-ii, Shangpin, WEIYE and Clever fish) were collected for calibration models by partial least squares (PLS) and artificial neural network (ANN). Firstly,...
A new instrument for the variety discrimination of fragrant mushrooms was designed and fabricated. First, the principle of using visible and near infrared (Vis/NIR) spectroscopy for variety discrimination of fragrant mushrooms was introduced. Then, the method of using error back propagation artificial neural network (BP-ANN) in the Vis/NIR spectral data analysis was elaborated. Before applying BP-ANN...
Visible and near infrared (VIS/NIR) spectroscopy combined with different calibration models was applied to predict the sugar content of white vinegars. The calibration set was composed of 240 samples, whereas 80 samples in the validation set. Partial least squares (PLS) models with or without pretreatments were developed and certain latent variables (LVs) were extracted by PLS analysis. The selected...
