Impact of Ultrasound Treatment and pH-Shifting on Physicochemical Properties of Protein-Enriched Barley Fraction and Barley Protein Isolate

Abstract: Ultrasonication alone or in combination with a pH-shifting method could be applied as means for improving the techno-functional properties and performance of barley protein ingredients in liquid food matrix. Ultrasound technology was utilised with and without pH-shifting to 3, 7 and 9 aiming at investigating their impact on primary protein structure, protein solubility, particle size and colloidal stability of an air-classified protein-enriched barley fraction and a barley protein isolate. Shifting the pH of s… Show more

“…The pulse protein has an important role in nutrition, and its techno-functional properties have a potential impact on the food system . In the food industry, proteins are processed and modified using physical, chemical, and enzymatic methods to improve their functional properties and food applications. The modification of several proteins including peanut protein, fava bean protein, soy protein, rice protein, rapeseed protein, and barley protein using different processing treatments was done to improve their functional properties and to boost their application in the development of novel foods. Incorporation of protein derived from germinated chickpea was found to enhance the qualities of the developed product, including nutritional, sensory, and consumer acceptability .…”

“…Therefore, ultrasound treatment has been shown to enhance the solubility of proteins in several studies [ 8 , 16 , 17 ]. Furthermore, it was shown that the efficiency of the pH shifting processing on pea protein [ 8 ], soy protein [ 6 ], and barley protein isolate [ 18 ] was enhanced when combined with ultrasound treatment.…”
