Abstract

The most important stage in the production of tinctures and aromatic alcohols is the extraction process. The paper aims to study the process of extracting target compounds from fruit and berry raw materials for the production of alcoholic tinctures. The research was carried out using a Soxhlet extractor. The experimental results were processed using the method of multiple regression analysis. As a result of processing the experimental data, the optimal technological regime parameters for the production of aromatic cranberry alcoholic tincture were selected. The cranberry tinctures produced at these parameters have a high content of target substances and reach maximum scores for taste, aroma and color. The obtained regression equations allow predetermining the quality of the resulting drink with a confidentiality of more than 90%. The use of the Soxhlet extractor allowed reducing the duration of the preparation of the cranberry tincture to 15 minutes, which is by times different from the classic method of tincture production. The use of the Soxhlet extractor allows reducing the consumed amount of solvent and raw materials, due to the almost maximum rate of the extraction. All this, in turn, affects the cost of the final product and the costs of the manufacturer.
