Research reveals nutritious potential of budding bush food

A bush food staple could be the centre of a new Indigenous industry, according to a University of Queensland researcher.

Sera Susan Jacob from the ARC Centre for Uniquely Australian Foods has identified the properties and potential of wattleseed, an edible seed or legume from the Australian Acacia, used traditionally as a staple food.

“Wattleseed has an incredible nutritional profile that is very different from traditionally known legumes, which creates an interesting market,” Sera said.

“The legume is currently used as a flavouring ingredient because of its taste and aroma, but my studies show there are different ways to take advantage of its nutritional properties by using it as a major ingredient.

“Most existing consumer products only use one variety of wattleseed, A.victoriae, when there are many others to consider.

“Wattleseed has similar protein content to other legumes but is very high in fibre and low in starch.

“It also contains compounds with a lot of anti-inflammatory and anti-carcinogenic benefits, which are important to today’s consumers.”

Sera Susan Jacob was part of a group that created recipes containing more than 20 per cent wattleseed.

As part of her PhD research, Sera worked with Northern Territory industry partners Karen Sheldon Group and Kungkas Can Cook to create recipes that contain more than 20 per cent wattleseed, compared with the three per cent found in most existing commercial products.

The recipes included a curry-style savoury dish and a muesli bar to appeal to consumers in regional and remote northern Australia, as well as a gluten-free vegan burger patty for the wider market.

Karen Sheldon Group director Sarah Hickey said the recipes met the recommended daily intake of iron, vitamin C and fibre in a child’s diet — components lacking in the diet of those with limited access to affordable, nutritious food.

“There is definitely a market for products that showcase wattleseed as they taste great and are packed with nutritional value,” Sarah said.

“Our objective is to ensure Indigenous Australians are involved in every stage of supply and that any value-add products are made where they’re wild harvested.

“Our intent is to close the circle of supply, so the seeds harvested on country also end up on the plates of those living on country, improving their diets along with their economic prospects.

“It’s about honouring and respecting Indigenous Australians who have taken such great care of these foods for more than 60,000 years so we can all continue to enjoy them.”

Sera said there were ample opportunities for the use of wattleseed, with more than 20 different species documented by Indigenous communities.

“The combination of scientific evidence and Indigenous knowledge is a powerful tool that community can use to successfully market and position their products and the formulations we’ve developed,” she said.

Educational materials from the research findings will also be created to be used in remote schools and community stores to pass on Indigenous knowledge and science.
