The justification of the shelf life and the quality assessment of juice-containing drinks based on genus Rubus berries

The purpose of the researches was to develop the recipe of soft drink on the basis of the juice received from berries Rubus chamaemorus, Rubus Saxatilis L. and coniferous cedar extract to carry out the assessment of its quality. The research problems were to develop the recipe of juice drink; to define the indicators of its quality; to investigate the dynamics of titrable acidity of drink in the course of its storage. The objects of the research were 5 prototypes of the juice drinks made of cloudberries berries (Rubus chamaemorus), stone bramble stony (Rubus Saxatilis L.) coniferous water extract of cedar. The results of the assessment of the quality of physical and chemical and organoleptic indicators were presented. The tasting assessment of juice drinks which allowed establishing the best version (compounding No. 4) from analyzed prototypes was carried out. Organoleptic assessment showed that with the increase in the share of sugar sour the smack goes down, at the increase in the amount of berry juice in compoundings, sour aftertaste increases, color becomes brighter...
