Main problem: the development of a new direction in the food industry – the so-called functional nutrition, which means the use of such products of natural origin, which, when systematically used, have a regulatory effect on the body as a whole or on its specific systems and organs, has been widely recognized all over the world: immunostimulants, biocorrectors for blood pressure, cholesterol levels, etc. When creating functional dairy products, ingredients of plant origin are increasingly included in recipes, which are sources of dietary fiber, vitamins and microelements, organic acids and other biologically active compounds, which can also serve as flavor fillers. Purpose: to develop a technology for the preparation of a fermented milk product with the addition of an extract from gourds. To do this, it was necessary: to select the amount (dose) of the yoghurt starter introduced into the prepared milk, and also to investigate the effect of temperature on the fermentation process of the drink; to investigate the amount (dose) of the vegetable filler introduced into the mixture and its effect on the organoleptic characteristics of the drink; to investigate the organoleptic properties of the drink with the melon culture extract added to it before fermentation and after fermentation; to investigate the effect of vegetable filler on the fermentation process; to investigate the effect of the dose of vegetable filler on the process of acid formation; conduct microbiological studies of milk and vegetable yogurt; to investigate the change in the acidity of milk and vegetable yogurt during storage; to investigate the effect of the freezing process on the chemical composition and biological value of the extract. Methods: when performing the practical part of the work, physicochemical, organoleptic and microbiological studies were used. Results and their significance: in the course of the study, it was concluded that by adding an extract of gourds to the technology for the preparation of fermented milk products, a new fermented milk product can be obtained that meets all physicochemical, organoleptic and microbiological requirements. As a result, an original method for the production of a fermented milk drink containing an extract from a melon culture was developed.
