A new Hort Innovation-funded research initiative delivered by CQUniversity is set to transform the quality and marketability of Australian-grown capsicums and chillis, helping growers reduce post-harvest losses and improve profitability.

The project, Optimising Capsicum and Chilli Quality (VG24002), will tackle common fruit defects such as internal rot, silvering, and pitting – issues that often lead to consignment rejections and reduced returns. One in four field-grown capsicums are lost to internal rot - an issue that drains A$53 million from the Australian horticulture industry each year. 

By working closely with growers across major production regions, the project will map supply chain performance, assess fruit quality using both digital and traditional methods, and develop best practice recommendations for production and post-harvest handling.

Hort Innovation CEO Brett Fifield commented: “This partnership is a powerful example of how targeted, science-backed research can deliver real-world benefits for growers. By funding this initiative, Hort Innovation is investing in practical solutions that improve vegetable quality, reduce waste, and drive profitability - strengthening the future of capsicum and chilli production and the broader horticulture industry.”

The project will explore how factors such as harvest maturity, vegetable structure, and cool chain processes influence quality. It will also develop predictive tools to help growers and supply chain partners anticipate retail performance and make informed decisions.

CQU researcher and chief investigator Karli Groves said the project’s grower-led approach is key to its success. 

“We’re working together with regional grower groups to ensure our findings are grounded in real-world conditions,” Ms Groves said. “Our goal is to empower growers with practical, actionable advice that will allow them to produce high quality capsicums and chillis at greater volumes.”

Bundaberg Fruit and Vegetable Growers CEO Bree Watson said they were proud to partner with CQUniversity to deliver the grower liaison component of this important project.  

“Our role is to ensure the research remains focused on delivering practical, commercially relevant outcomes for capsicum and chilli producers across Australia,” Ms Watson said.

This project has been funded by Hort Innovation, using the Vegetable research and development levy and contributions from the Australian Government. Hort Innovation is the grower-owned, not-for-profit research and development corporation for Australian horticulture.
