Abstract
The growing interest in functional food products in recent years has encouraged producers and researchers to develop new preservation techniques and processing methods that improve product quality. Vacuum impregnation is one such method, representing a non-thermal and non-destructive technology based on the hydrodynamic mechanism. Recently, it has been increasingly applied in the production of high-value food products through the incorporation of bioactive compounds into the food matrix. This study investigates the influence of vacuum impregnation treatment on the chemical composition of apple slices impregnated with apple juice and aronia berry juice, followed by convective dehydration. The results revealed superior values for the aronia-impregnated samples, characterized by increased contents of mineral compounds, dietary fiber, vitamin C, polyphenols, and anthocyanins compared with the apple juice-impregnated variant, which exhibited a less pronounced effect. The performed analyses confirmed that vacuum impregnation significantly influenced the chemical profile of dehydrated apples and demonstrated that this technique can be successfully used as a strategy for obtaining optimized functional food products.
