Nowadays, there has been increasing interest of using the chicory and its constituents in food production. The aim of this study was to compare physicochemical and sensory parameters of biscuits without (control) and with addition of 1, 3, and 5% of chicory fiber extract. The biscuits were subjected to physical (volume, maximum width, maximum height, aspect ratio at max. width, aspect ratio at max. height), chemical (dry matter content, crude protein, ash, fat, and crude fiber content), and sensory evaluation (flavor, chicory flavor (intensity), chicory flavor (presence), taste, chicory taste (presence), chicory taste (intensity), aftertaste, character of biscuit taste, overall acceptability). The volume, width, and height of biscuit increased after addition of chicory fiber extract and the highest values were obtained after enrichment with 5% of fiber extract. The crude protein content in biscuits increased from 6.76% (control) to 7.88% (5% of chicory fiber). Also the ash content increased from 0.68% (control) to 0.84% (5%) and the crude fiber content from 0.51% (control) to 0.56% (5%), respectively. Fat content was similar in all tested biscuit (∼24%). During the sensory evaluation, the highest scores were received with addition of 1 and 3% chicory fiber extract. We can recommend the application of chicory fiber in production of biscuits to improve nutritional (3 and 5% addition) and sensorial properties (1 and 3% addition) of this bakery product.
