Detection of peanut traces in wheat flour through NIR hyperspectral imaging spectroscopy

摘要

- NIR Hyperspectral images (1000-2200 nm) allowed the detection of peanut traces down to adulteration percentages 0.01 %ud- Determination coefficient of R2= 0.946 was found for the quantification of peanut adulteration from 10% to 0.1%.ud- The obtained results shows the feasibility of using HSI systems for the detection of peanut traces in conjuction with chemical procedures, such as RT-PCR and ELISA to facilitate quality control surveyance on food product processing lines.
