Abstract

One of the trends in modern nutrition is targeting people who care about their health. Confectionery made from sugar is in stable demand among people of different age groups, and research into their enrichment with vital nutrients is promising. One of the ways to implement such a task is the use of fruit and berry processing products, in particular in the form of pastes, during the production of candies. The purpose of the research was to evaluate the quality of cream-whipped candies with the addition of apple, quince and blackcurrant paste (40: 50: 10) during storage. It was established that the process of hydrolysis of the lipid component of candies with paste occurs at a higher rate compared to the control. This is due to their higher acidity and moisture. However, the fats of candies with the addition of fruit and berry paste are less prone to the formation of peroxides, which is explained by the presence in their composition of a significant number of polyphenolic compounds with pronounced antioxidant properties (anthocyanins and catechins), which are absent in the control sample. In particular, on the 60th day of storage, the value of the peroxide value for the sample with the additive was 27.9 % less than that of the control product. It has been established that candies with paste lose moisture more slowly due to the higher content of non-starch polysaccharides. Thus, on the 60th day, the moisture content of the control decreased by 11.33 %, and the product with paste decreased by 8.72 %. Smaller moisture losses ensure greater stability of their rheological characteristics during storage. It was noted that the strength and density of such candies increase more slowly than in the sample without the additive. The results of the research indicate the compliance of cream-whipped candies with fruit and berry paste to the normative storage terms in terms of oxidative stability of the lipid complex, physico-chemical and sensory indicators
