Validation of Multispectral Imaging (MSI) technology for food and feed analysis

Abstract

The current testing environment for food and feed samples is complex and uses a wide variety of analytical technologies that range from chemical to PCR-based. Whilst these approaches can be deemed fit for purpose in terms of their final analytical result, they tend to be highly specialised and require considerable frontend processing to ensure that the target analyte can be reliably detected and quantified. These combined sample processing and analytical requirements typically impact on testing times and have associated cost implications that must be factored into routine testing and monitoring applications. MSI uses multiple discrete and informative wavelengths covering regions such as the UV and near infra-red spectrum to quickly determine surface colour, texture and possible chemical composition. Compared to traditional molecular biology approaches utilising DNA extraction followed by PCR-based analyses, MSI can simplify and reduce the time/costs associated with sample analysis. It is rapid and non-destructive.
