Abstract
The objects of the research are fruit and berry juices from watermelon, rosehip, apples and pumpkin. The influence of the physico-chemical parameters of fruit and berry juices on the process of storage and blending is investigated. It has been found that quantitative regulation depending on the physico-chemical parameters of fruit and berry juices during the development of blended juice technology makes it possible to develop a drink with a long shelf life. The developed juices should satisfy the body's needs for vitamins and minerals in food necessary for the normal development of the body. Based on research, watermelon-pumpkin-rosehip juice is recommended. However, the consumer properties of natural juices depend on the variety and climatic conditions of growth. The climatic conditions of growth and the variety significantly affect the physico-chemical parameters of the juices obtained from them. All this allows us to assert that it is advisable to conduct a study devoted to establishing the influence of the physico-chemical parameters of fruit and berry juices based on watermelon juice on the process of storage and blending. Juices are the most technologically advanced product for creating new types of functional nutrition. In addition, they contain a complex of vitamins and minerals in their composition. In connection with the above, the development of technology and the organization of the production of functional purpose juices are the solution to problems related to nutrition. It is found that the resulting new product – watermelon-pumpkin-rosehip drink will allow you to get a new product with high quality indicators and expand the range of fruit and berry drinks based on watermelon juice
