Legumes are considered highly nutritious and sustainable food. Accordingly, there is a steady growth in the consumption of legumes worldwide, including in Australia. Due to lengthy soaking and cooking times, consumers prefer ready-to-eat canned legumes. The current processing technologies are energy and water-intensive and generate considerable waste. This project investigates the application of non-thermal technologies to reduce processing time, water and energy use and enable the recovery of valuable polyphenols and soluble dietary fibres normally lost in the wastewater. This knowledge will lead to sustainable beans processing, delivering improved productivity to Australian manufacturers and quality food to Australian consumers.Read moreRead less

This project aims to develop an innovative multiscale model for food drying, which integrates spatial and temporal nonlinear behaviours at different scales. The proposed unifying theory will capture dynamic micro level features and upscale them to macro level features through a concurrent bridging scheme. As cellular elements critically govern the drying process, the fundamental understanding captured through this theory will lead to more accurate prediction of drying kinetics, deformation and quality changes, and hence the development of efficient drying systems. This project will overcome a longstanding research problem and position Australia at the forefront in world drying research to reap substantial economic benefits for Australia.Read moreRead less

Risk Profile For Paralytic Shellfish Toxins In Tasmanian Periwinkles

Summary
Recurrent harmful algal blooms in Tasmanian waters (Gymnodinium in the South and Alexandrium on the East Coast) have impacted Oyster, Mussel, Abalone and Rock Lobster industries, necessitating the implementation of biotoxin monitoring programs and harvest closures during high risk periods.

It is currently unknown whether Periwinkles can accumulate paralytic shellfish toxins (PST) from Tasmanian microalgal blooms and a conservative risk management approach has been taken thus far to protect both public health and market access.
Unlike bivalve shellfish, Abalone and Rock Lobster, there is currently no clearly defined biotoxin management plan for Periwinkles in Tasmania. As grazers, Periwinkles are loosely grouped with Urchins and Abalone, the latter of which are a proven PST risk. This Abalone biotoxin sampling plan is triggered when Tasmanian Shellfish Market Access Program (ShellMAP) closes bivalve harvest areas due to PST risk. In a conservative approach, the current recommendation is PST analysis of 20 pooled Periwinkles per Abalone block on at least a monthly basis to maintain market access. This presents a considerable cost burden to the small dive fishery and interrupts harvest operations, as PST sampling of Periwinkles is required if elevated PST are detected in Abalone, which are known to hold onto PST for longer time periods in between blooms (years).
To date, the vast majority of Periwinkle samples that have been analysed for PST were collected from weak or no bloom years or regions. Evidence from French tank trials exposing the common European Periwinkle (Littorina littorea) to Alexandrium minutum cysts containing PST showed significant toxin uptake (0.2 mg PST/kg) within six days of exposure (Neves et al, 2015). It remains unknown whether commercially harvested Tasmanian Periwinkles (Lunella undulata) are at risk of PST accumulation and if the current conservative monitoring approach is commensurate to risk. In such scenarios, risk managers will commonly outsource a preliminary risk assessment (known as a risk profile). Risk profiles are an important tool for risk managers and industry. They provide a summary of all information pertinent to food safety associated with the specific hazard/food combination. The purpose of a risk profile is to assist initial risk management activities, such as identifying future actions required (if any), and the options for food safety management programs. They also inform the level of resourcing required to control the hazard/food pairing.
This project will deliver an urgently required risk profile for PST in Periwinkles to inform future actions (if any) and provide options for cost-effective food safety management programs. This profile will: 1. Determine the risk of PST accumulation in Periwinkles in Tasmania as a result of harmful microalgal blooms during high risk exposures at peak algal bloom densities in the field and in tank trials. 2. Outline potential management options and knowledge gaps, should risk management be necessary. This includes an assessment of whether the bivalve PST regulatory limit is appropriate to use in Periwinkle risk management (currently based on shellfish serving size of 100-400g) and the spatial variability associated with sampling.

Objectives: 1. Determine whether Tasmanian Periwinkles can bioaccumulate PST from Alexandrium and/or Gymnodinium microalgal blooms during both field and laboratory exposures. 2. Identify the most suitable size of biotoxin management zones for Periwinkles. 3. Assess whether the use of the bivalve PST regulatory limit is appropriate for Periwinkles by conducting a literature search and consumption survey. 4. Generate a risk profile for PST in Tasmanian wild caught Periwinkles and provide guidance for risk management. Read moreRead less
