Abstract:Near-infrared hyperspectral imaging (NIR-HSI) was investigated to detect the contamination of shrimp powder (SP) in tuna powder (TP) with partial least squares regression (PLSR) model. The principal component analysis was performed with NIR-HSI data for classification of tuna and shrimp powder. Samples for NIR-HSI data analysis were prepared using tuna powder contaminated with shrimp powder in concentration of 0%, 0.01%, 0.05%, 0.1%, 0.5%, 1%, 5%, 10%, 25%, 50%, 75% and 100% (w/w). The NIR-HIS in a wavelength … Show more
