Researchers at the North Caucasus Federal University have developed an ultrasonic method to recover dairy raw materials, reducing the need for artificial additives in dairy products. The technique involves reagent-free whey recovery using ultrasound, eliminating the need for chemical stabilizers and preservatives. The team has secured a patent for a method to produce yoghurt from milk powder using ultrasonic cavitation, which has been adopted by a major dairy plant in the Stavropol region.
