In the present study, a novel drying technique using a combination of ultrasound and vacuum dehydration was
developed to shorten the time for the drying of beef and chickenmeats.
The meatswere dried using three different
techniques, namely ultrasonic vacuum(USV) drying, vacuumdrying and oven drying at 55, 65 and 75 °C.
The
meats dried faster with USV thanwith the vacuumand oven drying techniques.
The drying time for the USV, vacuum and oven drying techniques at 75 °C was determined as 300, 480 and 750 min for beef and 330, 570 and 780min for chicken, respectively.
The drying ratewas significantly influenced by the drying techniques and temperatures.
The lowest energy consumption was determined in the USV technique.
The drying data were successfully fitted to 10 models (R2: 0.9140–0.9991).
According to the results, the USV drying technique shortened the
drying period of beef and chicken.
Industrial relevance: Beef and chicken meats dried fasterwith the USV drying method than with the vacuumand oven drying techniques.
The novel drying technique could be used to improve efficiency of the vacuum drying
technique.
Combination of ultrasound and vacuum treatment consumed lower energy compared with oven
and vacuum drying.
