Australia: Research team aims to extract high quality proteins from processing wastewater

Researchers dr. Jocelyn Midgley (Simplot Australia) and professor Vicki Chen, from UNSW School of Chemical Engineering in Sydney, Australia, associate professor Jayashree Arcot and PhD student Shirin Dabestani, plan to find a solution to extract valuable high quality proteins from wastewater. Wastewater effluent from the food processing industries contains high concentrations of potassium, COD and BOD (chemical and biochemical oxygen demand) caused by the presence of starch, proteins, amino acids and sugars. The waste stream from the potato processing industry particularly contains considerable amounts of these valuable by-products. Protein, particularly plant protein, is a food trend that has been gathering increasing momentum with consumers. Although the level of protein in this wastewater is low, large volumes of potatoes are processed, thus for Simplot Australia the project was an investigation of opportunities. More
