Abstract
In recent decades, many herbs and fruit and berry raw materials have attracted increased interest as basic and supplementary physiologically valuable ingredients. As a consequence of nutrition imbalance from the position of insufficient consumption of mineral components, antioxidants, vitamins, etc. Resource raw material potential of the Kaliningrad region allows to actively use plant (fruit and berry) raw material resources in technologies of food products for their enrichment with micronutrients. The objects of research in the work were berries of hawthorn (Sorbus aucuparia), growing on the territory of the Kaliningrad region, collected in September 2023. The optimal dosage and type of enzyme preparation influencing the juice yield were established in the work. The best results were established when using pectoletic enzymes, and increasing the dosage of enzyme preparations uniformly increases the juice yield on average in the treatment of Fructotsim Collor by 13 %, in the treatment of Pectinex XXL the juice yield increases on average by 17.7 % compared to the control. However, it should be noted that the most active limit of saturation with pectic enzymes occurs at a dose of 0.03 %, with further increase in dose there is a slight decrease in juice yield.
