The Australian wild abalone industry currently produces abalone valued at ~$300 million; however production volume has been diminishing over the last five years due to reduction in catch quotas to maintain sustainable harvests, climate variability and recovery from diseases. Therefore, there is a need to maximise resource use – ‘make more from less’. The currently underutilised abalone processing waste (i.e. shucked viscera and blood) provide attractive value adding targets to explore in novel ways (e.g. nutraceutical/functional food outcomes, pet food supplements).
To determine the scale of this opportunity, this project will map domestic and export abalone supply chains to quantify:
(i) volumes of waste produced
(ii) nutritional, biochemical composition and assessment of nutraceutical activity.
Under the TRANSFORM Program, opportunities to utilise current volumes of discarded viscera and blood will be identified in the ‘waste map’ and subsequently explored.
The project will initially map abalone production waste streams for volume, quality, format and location. Nutritional and other analyses will be conducted on the various waste streams to inform the development of alternate end products. Particular focus will be on identifying viscera product characteristics of functionality and health wellbeing outcomes. End product outcomes, in the form of pet food supplements and human nutraceutical/functional food outcomes will be investigated, initially for technical feasibility and later for market and economic feasibility. Where relevant and supported by ACA and partners, commercialisation will be undertaken.
Broadly the project objectives are:
August 2021 – July 2025
