Impact of power ultrasound on chemical and physicochemical quality indicators of strawberries dried by convection
[EN] A study on the quality parameters of strawberries dehydrated by convection assisted by power ultrasound (US) at 40 70 C and 30 and 60W has been carried out for the first time. In general, the quality of US-treated samples was higher than that of commercial samples. Even under the most severe co...
