Abstract: The object of research is a pastila with the replacement of 75% of apple puree with a fruit and berry paste based on apples, cranberries and hawthorn. One of the most problematic areas is the lack of research on the patterns of changes in the quality indicators of pastila with a paste based on apples, cranberries and hawthorn during storage. The relevance of the work is due to the need to expand the range of sugar confectionery products with a foamy structure, namely pastila, using fruit and berry raw materials and assessing their quality during storage. The research aimed to determine the nature of changes in the quality indicators of a pastila with a fruit and berry paste based on apples, cranberries and hawthorn compared to a control sample with apple puree, during storage for 40 days. It was found that the pastila with a multi-component fruit and berry paste lost moisture more slowly than the control: over 40 days the rate of its loss was 5.9% lower. The addition of paste also contributed to the slowdown in the increase in product strength. After 40 days, the strength of the pastila with paste increased by 10.0%, while the strength of the control – by 18.4%. The content of reducing substances and acidity during storage increased statistically insignificantly. After 40 days of storage, no bacteria of the E. coli group were detected in the samples. The number of mesophilic aerobic and facultative anaerobic microorganisms, yeasts and mold fungi did not exceed the maximum permissible levels. In the pastila with fruit and berry paste, the accumulation of microorganisms occurred more slowly than in the control sample. The average organoleptic score of the pastila with paste after 40 days was 4.83 points, which corresponded to the level of the control sample on the day of manufacture. The control score on day 40 decreased to 3.90 points. The results obtained justify the feasibility of extending the recommended shelf life of pastila using a multi-component fruit and berry paste based on apples, cranberries and hawthorn from 30 to 40 days.
