I'm not the demographic but there is good news for those who favour Vegan-friendly meals.
Chemical engineers at UNSW Sydney have created a plant-based cheese that melts, stretches and browns under the grill like the real thing, creating the opportunity for more realistic dairy and meat alternatives that blend plant proteins with complex carbohydrates.
“Colours and flavours are the easy part,” says Professor Cordelia Selomulya, who has been working on plant-based food textures at UNSW since 2019. “But replicating the structure - that pull of melted cheese, or the juicy mouthfeel of meat - is the real challenge.”
While plant-based alternatives have been on the market for many years, some of today’s products still fall short as they behave strangely under heat, fail to effectively deliver the nutrition promised on the label - including sufficient protein - or simply lack the sensory properties of dairy-based products.
Professor Selomulya and her team at the UNSW School of Chemical Engineering (above) are actively working to change that, by working on layering plant-based proteins with naturally occurring polysaccharides - complex sugars and dietary fibres - to mimic the ‘feel’ of animal products.
This also helps ensure the foods hold up under cooking and the freeze-thaw cycles of long-term storage, while also releasing nutrients during digestion.
The team’s most recent breakthrough is a plant-based cheese that pairs pea protein with polysaccharides for a more ‘lifelike’ texture.
“By focusing on polysaccharide blends, we’re now able to achieve the kind of elasticity and structure you'd normally associate with dairy cheese,” says Dr Yong Wang, a lead investigator on the project.
“We’ve also made progress in preserving key nutrients, which is something most commercial products don’t do well.”
Now for selling the innovation.
“The next step is to find commercial partners,” Professor Selomulya says.
“We now have a process that is easily scalable, we don't need special equipment, and we have a provisional patent that we can license.”
Australia’s plant-based food market is expected to hit $13 billion by 2030. This is despite most current products relying on soy or gluten for plant proteins – which are common allergens.
