What is it about?

Polyols (erythritol, xylitol, and maltitol) may be used as components in osmotic solutions. Are they good alternatives to sucrose for osmotic dehydration (OD) of apples? Apples of the Ligol variety collected in the Mazovia region, Poland were used as raw tissue in the osmotic dehydration experiments. Let’s try to apply the appropriate drying method after the pretreatment!

Why is it important?

The polyol solutions were equally or significantly more effective in the OD of apples compared to the commonly used sucrose solution. Regardless of the type of osmotic solution, the water loss of apples was from 2 to 10 times greater than solid gain.


This paper includes results of laboratory research focused on the pretreatment and drying stage. We believe that it is a good way to create products with high qualities due to the lack of added sugars.
