In view of the growing expectations of meat products consumers (quality and sensory properties), the meat industry must develop functional products to meet the consumer requirements. In the experiment, the influence of oat β-glucan, canola oil and both on the proximate composition, fatty acid profile, volatile compounds profile and sensory properties of beef burgers was analyzed. The beef tallow replacement by β-glucan, canola oil or both decreased the SFA and increased PUFA content. The consumption of one portion of product with canola oil and β-glucan can provide 57.6% of the daily amount of linolenic acid (C18:3n3). Volatile compounds analysis of grilled samples showed the presence of 1-penten-3-one and 2-methylpropanal only in case of groups with canola oil and butane-2-one in β-glucan group. This strategy improves not only the nutritional value but also the sensory properties and consumer acceptance. The obtained product may be labelled with health claims regarding oat β-glucan.
