This study produced innovative baked goods enriched with flaxseed, which is rich in omega-3 fatty acids, and tested their omega-3 content and in vitro antithrombotic/anti-inflammatory effects. The results showed that the enriched products had stable high concentrations of omega-3 fatty acids and exhibited higher antithrombotic/anti-inflammatory activity compared to conventional products. The consumers evaluated the products positively and they offer a promising opportunity for the development of locally consumed functional foods in the post-COVID-19 era.
Flaxseed is a natural ingredient with health benefits because of its rich contents of omega-3 fatty acids and fiber. In this study, whole-meal sliced bread, chocolate cookies, and breadsticks, which were enriched with flaxseed (Linum usitatissimu) were produced as a natural enrichment source in order to provide functional baked goods. The three innovative products were tested as sources of omega-3 fatty acids in terms of alpha-linolenic acid according to EU 1924/2006 as well as for their in vitro antithrombotic/anti-inflammatory effect. The results showed that omega-3 fatty acids had high concentrations (>0.6 g per 100 g of product) in all products even after the heating treatment with constant stability during the time of consumption. All the enriched products exerted higher, but in different grade, in vitro antithrombotic/anti-inflammatory activity compared to the conventional products. The products were evaluated positively by a panel of potential consumers without significant differences compared to conventional corresponding products. Enriched bakery products with omega-3 fatty acids may represent a novel opportunity for the development of functional foods that can be locally consumed, thereby contributing to public health prevention measures that the post-COVID-19 era demands.
