Australian industry, scientists give ugly vegetables a nutrient-rich facelift

As part of an industry-led drive to reduce waste, Horticulture Innovation Australia and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) are working with growers to turn imperfect-looking vegetables into nutrient-rich snacks and supplements. 

In a release, Hort Innovation chief executive John Lloyd said the project was investigating how good nutrients, or phytonutrients, could be drawn from carrots, broccoli and other vegetables.

"Limiting the amount of produce left in the field and offcuts cast aside during processing is a priority for industry because there’s so much potential there. On top of this, Australians are not eating enough vegetables," he said.

"This project is addressing both these issues by determining a way we can turn underutilized produce – such as ugly veggies that are not to specification – into high-value, super-high-nutrient ingredients and products."

As part of the project, researchers are investigating the use of separation, extraction and stabilization technologies to create products that can be sold as powders, concentrates or vegetable-dense snacks for children.

CSIRO chief research scientist Dr. Mary Ann Augustin said research showed farms could lose up to 40% of produce and growers wre keen to see this stop. For that reason, and because it has great health benefits, fermentation of vegetables is also a significant area of focus of the project.

"Fermentation is a great natural way of delivering the good bacteria through food. We are investigating ways vegetables lost in the food supply can be processed and presented in a consumer-friendly manner because it has huge health benefits,” she said.

Dr. Augustin also said feedback from growers is that processing plants need to be more accessible as many producers cannot justify the expense of freighting unused produce long distances.

"We are also looking into the interest in setting up processing hubs in key growing regions to make it easier for growers to process their underutilized produce and create these high-value, nutrient-dense products," she said.

The desired outcome is also to encourage new industries and employment based on new edible food ingredients and products from the underutilized vegetables that will provide more returns to farmers.

John Said, the chief executive of one of the largest lettuce and brassica farmers in Australia, Fresh Select, said any project that armed industry with the tools it needed to minimize produce loss was positive.

“We are very excited by the potential of this research project and are proactively supporting this initiative to reduce food waste," Said said.

It will not only benefit growers and the industry, it will also benefit the Australian population by providing high-nutrient products and improving the nation’s health”. The project is due for completion late 2018.

The project has been funded by grower-owned, not-for-profit research and development corporation, Horticulture Innovation Australia, using vegetable levies and funds from the Australian Government, with co-investment from the CSIRO.
