The aim of the present study was to investigate the application possibilities of berries marc in wheat bread making to improve its quality. Sensory evaluation was used to determine the liking degree of bread with berries marc. Twenty samples of wheat bread with raspberries, white currants, gooseberries and seabuckthorn marc were produced by using standard technology. A 9 point hedonic scale was used to find out the degree of liking. The sensory data were analyzed using analysis of variance (ANOVA) and Tukey's test. The results of hedonic scaling show that berries marc (5-10% of the flour mass) can be used in baking wheat bread.

The task of the research was to study the chemical composition of sea buckthorn and raspberry marc as well as of high milling wheat bread with berry marc. Wheat bread, i.e. the control sample and the bread samples with 3%, 5% and 7% (from the flour mass) of raspberry and sea buckthorn marc, was baked in the experimental bakery. The content of sugar, fat, protein, fibre and titratable acids was determined by using standard methods. The content of vitamin E, carotene, pectin and phenol compounds was determined by using spectrophotometric method. The obtained results prove that sea buckthorn and raspberry marc have fibre, fat, sugar acids, carotene, phenol compounds, vitamin E, and pectin. The content of fibre and carotene increased in wheat bread samples when raspberry and sea buckthorn marc was added. Depending on the amount of marc added to the bread, the changes in the content of fat, sugar, and carotene in wheat bread samples were studied. The wheat bread with raspberry and sea buckthorn marc contained vitamin E and phenol compounds.
