Abstract
The nettle (Urtica dioica L.), which is well-known for its properties, is widely spread throughout the temperate and tropical zones around the world. The aim of this product is to enrich bakery products by fortification, thus their nutritional value being raised. This has a positive impact on the consumers who, nowadays, take a growing interest in functional products which are rich in active compounds. Bread enriched with flour from nettle seeds is a product with high nutritional value. The innovative feature of this product consists in its being enriched with essential fatty and amino acids by the addition of 3%, 6% and 9%, respectively, of nettle seed flour. As a result, products with higher nutritional and functional properties have been obtained. The new products, thus, have had increased contents of protein (from 6.60±0.14 to 7.16±0.14%) and fat (from 17.48±0.11 to 2.85±0.21%). Moreover, the content of polyphenols also increased from 49.88±0.42 to 88.55±0.96 mg EAG/100 g, whereas the antioxidant activity increased from 56.81±1.10 to 77.91±0.77%. According to the sensory analysis by using the hedonic test the most appreciated bread was found to be that with 6% flour from nettle seeds. In terms of the texture analysis, the control sample compared to the samples with 3% and 6% added flour showed close results; a decrease was though noted in the sample with 9% added flour as compared to the control.
