US treatment can also increase the heat transfer coefficient,which can also accelerate
the removal of moisture from the sample due to higher heat transfer.
Drying time differences between the USV and the vacuum or oven drying technique increased as the drying temperature increased.
Decreasing drying time is very important for the food industry since meat includes fat, which is degraded to peroxides when it is subjected to heat treatment.
Lipid oxidation causes deterioration in the quality of meat products, and thus decreases storage shelf life and nutritional value and negatively affects organoleptic characteristics.
Therefore, fats could be less damaged when meat is dried with this novel drying technique, USV,and vacuum drying instead of oven drying.
In addition, decreasing the drying period is significant for products that contain the rmolabile substances.
As seen in Table 3, the opposite trend between the drying time and the drying rate (DR) was observed, meaning that the DR increased with the drying temperature.
