Anotace: Sugar cookies are the most common among flour confectionery, they have high energy value and insufficient content of basic nutrients. Excessive consumption of cookies can lead to a number of diseases. This necessitates the development of new food products of everyday demand, including flour confectionery products of high biological value. The paper studies the effect of pumpkin seed pomace on the production of sugar biscuits with the increased biological value. The results of the commodity examination of the developed cookie sample are presented and the comparison with traditional samples of sugar cookies of other producers is carried out. The expediency of using pumpkin seed pomace in the technology of sugar biscuit production has been proved to expand the range of high biological value confectionery products and products with the reduced level of caloric content.

Through simulation it has been found that the optimum amount of pumpkin seed pomace is 2.76 % (18 g) of the weight of the flour. With an increase in the amount of pomace the ability to soak decreases, which is why this ratio will contribute to the enrichment of sugar cookies and the preservation of the quality of physics-chemical indicators. The addition of pumpkin seed pomace to cookies composition positively influenced the chemical composition of the ready product, saturating it with proteins, food fibers, polyunsaturated fatty acids, vitamins and minerals. After all, when consuming 100 g of the product there are tendencies in compensation of more than 10 % of daily norm in proteins, fats, carbohydrates; mineral substances - from 2.33 % to 25.78 %; vitamins from 3,35 % to 9,44 %, which is explained by the positive effect on the body and satisfying basic nutrients to different categories of the population.

The dynamics of changes in the quality of the developed sample at the time of fabrication and after its storage was investigated. It is proved that organoleptic parameters change basically - there appears a taste and a smell of rancidity, which is explained by the oxidation of fats.
