A Guide to Employ Hyperspectral Imaging for Assessing Wheat Quality at Different Stages of Supply Chain in Australia: A Review

TL;DR

This review explores how hyperspectral imaging can be used as a non-invasive, real-time method to assess wheat quality throughout the Australian supply chain, addressing limitations of traditional techniques.

Contribution

It compiles and analyzes existing literature on hyperspectral imaging applications for wheat quality assessment at various supply chain stages in Australia.

Findings

HSI enables non-destructive wheat quality measurement.

HSI can be applied to bulk wheat samples.

Literature indicates HSI's potential for real-time assessment.

Abstract

Wheat is one of the major staple crops across the globe. Therefore, it is mandatory to measure, maintain and improve the wheat quality for human consumption. Traditional wheat quality measurement methods are mostly invasive, destructive and limited to small samples of wheat. In a typical supply chain of wheat, there are many receival points where bulk wheat arrives, gets stored and forwarded as per the requirements. In this receival points, the application of traditional quality measurement methods is difficult and often very expensive. Therefore, there is a need for non-invasive, non-destructive real-time methods for wheat quality assessments. One such method that fulfils the above-mentioned criteria is hyperspectral imaging (HSI) for food quality measurement and it can also be applied to bulk samples. In this paper, we have investigated how HSI has been used in the literature for assessing stored wheat quality. So that the required information to implement real-time digital quality assessment methods at the different stages of Australian supply chain can be made available in a single and compact document.
