FAYETTEVILLE — Food science researchers with the Arkansas Agricultural Experiment Station are tapping into the power of soundwaves and fermentation to improve the quality of plant-based proteins.
Ultrasound, the same soundwave technology that creates images of babies in the womb, and microbes that break starches down into sugar are behind a new protein extraction method being investigated with the support of a nearly $300,000 grant from the U.S. Department of Agriculture’s National Institute of Food and Agriculture.
Propelling the study is an increased demand in the plant-based dairy and alternative meat markets. Mahfuzur Rahman, an assistant professor in the food science department, said the market was estimated to be worth $29 billion in 2023 and growing by about 8 percent annually. Health and environmental concerns are behind the increase in demand, he noted.
Rahman is the lead research on the two-year study that began in August to develop an eco-friendly method of plant-protein extraction to enhance consumer acceptance by improving product development performance, taste and nutritional value. Plant-based proteins are used to make alternatives to animal proteins found in meats and dairy.
“Traditional protein extraction methods require chemicals such as sodium hydroxide, sodium carbonate, sulfuric acid, hydrochloric acid and often result in lower yields and reduced protein quality,” Rahman said. “The traditional method affects the functionality, taste and nutrition of the extracted proteins.”
