3.1. Nutritional composition
Data on the basic chemical composition of cookies are presented in Table 1. In both refined and wholegrain groups of cookies, supplementation caused lowering of the carbohydrate and moisture content and increased the ash, protein and cellulose contents. The fat content increased significantly only in the case of enrichment with sunflower seed, due to the high oil content of sunflower seed. The addition of sunflower seed significantly increased the α-tocopherol content, whereas barley flour increased the β-glucan content. As the supplementation level increased, these effects were more prominent.
