The effect of distillation systems on the quality of apple distillates

Apple distillates are a common drink in Western European regions and considered as a high quality product. There are many factors that will influence the production and the quality of apple distillates. The aim of this work was to produce apple distillates by column devices with different rectification index (1, 1.75 and 2.6) and by alambic device (classic process and double distillation). Distillates were analyzed to determine chemical composition, aroma profile and sensory properties. Apple distillates produced by column process had significant higher ethanol content, but lower aldehydes, higher alcohols, esters and monoterpenes. All samples had very low concentration of methanol and furfural. Apple distillates produced by column process had significant higher grades of sensory properties.
