Traceability Grants Program

Project title: Robust Digital Technology for End-to-End Traceability in Australian Grain Export Supply Chain

This project is part of the Traceability Grants Program funded by the Commonwealth of Australia.

Blockchain technology to build the traceability system.


Traceability technology is fast gaining significant attention in the food and agriculture industries. Although substantial work has recently been done globally on advancing traceability technology for some food industries (e.g. horticulture and agriculture), there is only limited work focusing on grain traceability specific to the Australian grain export supply chain. Our project will address this critical technology gap with close collaboration between researchers and industries in Australia in key export markets.


We will work with the relevant industry and the involved stakeholders to prioritise the following:

  • key tests that will benefit from automation and sensing technologies
  • key traceability platform functionality that will record test results and secure the data traceability in the supply chain
  • demonstration of these components as a pilot for pre-commercialisation
  • probable commercialisation steps through heavy engagement with industry partners and government

Proposed solutions

  • a blockchain-based digital traceability pilot platform which robustly tracks grain quality in the entire supply chain
  • digital traceability approaches to security standards, certifications and audit procedures that provide a model for wide implementation in the grain industry
  • understanding amidst the trusted parties of the blockchain tolerated power of adversary, identity and execution, scalability, security and privacy
  • new non-destructive sensing techniques (e.g., multispectral and hyperspectral cameras) for grain quality that are accurate, fast and robust for environmental conditions – e.g. lighting condition variations and shaking of cameras resulting in noisy images during transportation and storage
  • a grain quality decay model for identifying the supply chain steps where any non-compliance of food safety originates from. This could also be used as a modelling tool to predict when and where non-compliance might occur if there is any disruption to the supply chain to cause logistics conditions to change.

Hyperspectral imaging

An example of new non-destructive sensing techniques for grain quality is hyperspectral imaging.

The hyperspectral images (right) show insect infestation in wheat kernels. In contrast, minimal information of insect-damage can be obtained by standard optical images (left).*
