The School of Agriculture, Food and Wine at The University of Adelaide has partnered with South Australian businesses to develop functional foods, and sustainably produced, high quality products.

Several projects funded under the Advanced Food Manufacturing (AFM) grants program are taking an innovative approach to develop new or improved food products or manufacturing processes and help drive greater innovation in South Australia’s food industries.

Advanced Food Manufacturing Grants are an initiative of Primary Industries and Regions South Australia, through the South Australian Food Innovation Centre (SAFIC), in partnership with Food Innovation Australia Limited. The University of Adelaide is a Foundation Partner of SAFIC.


A premium apple sprit made from leftover cider pulp is the goal of this collaboration between the Hills Cider Company and the University of Adelaide.

“When we crush the apples to make our cider, we leave behind a large amount of apple pulp,” Hills Cider Company Director Steve Dorman said. “This project is about turning a common industry waste stream into a new, high-value food product that fills a gap in the spirits market in Australia and has fantastic potential in overseas markets”.

School of Agriculture, Food and Wine researchers have carried out trials using the apple pulp to determine the best way to ferment the residual sugars and produce the base apple wine; this is then distilled to create unique apple spirits.

“We want to determine the optimal process for the fermentation of the pulp – for instance, what temperature we should use, how much material to ferment at a time, which yeast strains to use,” said lead researcher Associate Professor Kerry Wilkinson.

After fermentation, the next step is to distil the end product to make a spirit base that can be blended with other products. “It is not too dissimilar to brandy production, but the different starting material produces unique aroma and flavours,” Kerry said.

The researchers at the Waite campus have been able to produce an apple spirit, which exhibits apple, pear and stone fruit characters.

“Ideally, the alcohol content of the base wine needs to be higher before we can try distillation on a commercial scale, so fermentation trials are ongoing.”

Other potential uses for the pulp waste are also being explored, including the production of an apple flour and apple cider vinegar.

This project was awarded $45,000 in Round 3 of the Primary Industries and Regions South Australia Advanced Food Manufacturing Grant Program (2017).
