Scientific Substantiation of the Technology of the Functional Beverage, Based on the Rowan Juice with Vegetative Extracts Use

Abstract

Topicality. Modern manufacturers of foodstuff and beverages are faced with the task of creating the new generation nutritive – sanative and functional, including drinks, that can have a positive impact on consumers’ health condition. Functional beverages are intended for systematic usage in the diet compound for all healthy population age groups; they are able to reduce the risk of diseases development, caused by nutrition, maintain and improve health state due to the presence of physiologically functional ingredients in their complement (vitamins, phenolic compounds, dietary fibers, carotenoids, organic acids, minerals). Aim and methods. The aim of this article is to substantiate the rowan juice choice for the functional meaning drink creation, to determine its composition and physico-chemical indicators, the selection of effective formula components with antioxidant effect, and the working of the non-alcoholic drink with sanative qualities technology. In this work standard organoleptic, physico-chemical and calculated research methods are used. Results. It was proved that the rowan juice should be used as the basis for the juice-containing beverage of functional meaning. For maximal juice extraction, it is necessary to pre-freeze the raw material, followed by its grinding and enzymatic preparation machining. Green tea and sage extracts, which are sources of antioxidant effect substances, were chosen as a supplement to the rowan juice. Discussion and conclusions. It is established that the non-alcoholic juice-containing beverage belongs to the category of functional foodstuff, as during its using the level of daily needs providing of ascorbic acid, β-carotene, pectin, bioflavonoids, catechins is within 10...50%. The scientific novelty of this research lies in the technology development of the juice-containing functional beverage on the basis of rowan juice with vegetative extracts use. The practical significance of the received results is in their usage at enterprises, producing non-alcoholic beverages, in restaurant industry and sanatorium-resort catering establishments.
