Near infrared hyperspectral imaging for foreign body detection and identification in food processing

摘要

Hyperspectral imaging (HSI) combines imaging and spectroscopy for enhanced non-destructive analysis of materials. When combined with chemometric (i.e. multivariate) analysis, HSI can be applied for prediction of the concentration and distribution of multiple components in a sample. This makes the technique attractive for many routine quality inspections within the food industry.~1 One potentially useful application of HSI is foreign body detection in food processes.
