Quality of wheat bread enriched with onion extract and polyphenols content and antioxidant activity changes during bread storage
Addition of onion skin extract (OE) to wheat bread enriches it in polyphenols and flavonols and increased antioxidative activity of the final products. The total content of flavonols in breads with the OE depended on the amount of added OE and also storage temperature. Breads enriched with OE had a proper external appearance as well as crumb and crust features. Roasted onion aroma and taste were perceptible in the obtained breads. Consumers rated the taste of bread with 1% OE lower than a classic because it was bitter.
