The aim was to recognize the effect of oat β-glucan fiber addition on expected and perceived liking of fresh pasta. Durum wheat semolina was enriched with oat β-glucan fiber in proportions: 0, 4, 8, 12 and 16% in relation to wheat flour. The evaluation of pasta samples was carried out by a group of 150 consumers and 10 panelists. Consumers evaluated pasta samples to assess the expected and perceived liking and the trained panelists established sensory profile.The consumers’ evaluation of cooked pasta with different oat β-glucan fiber additions showed that the sample with 16% oat β-glucan fiber addition was most liked (6.4 in a 1–9 scale). Consistency between expected and perceived liking increased with the increase in oat β-glucan fiber addition and was the highest for the sample enriched with 16% β-glucan. The sensory profile established by the trained panelists compared with the results of the consumers’ assessment showed that an increase in intensity of bran odor and flavor (up to value 4.08 for odor note and 5.31 for flavor) could have been related to higher perceived liking by the consumers. The increased amount of oat β-glucan fiber powder (16%), which provides fiber-rich products, is a promising ingredient for fresh pasta formulation.
