Abstract
Cookies, muffins and baguettes were formulated with Korean wheat flour and compared with those made from imported wheat flour in terms of total phenol content, antioxidant activity, and in vitro protein digestibility (IVPD). Chunnyencho and Honghawsi were added to improve quality of the bakery products. Addition of Chunnyencho did not show any significant improvement, whereas Honghawsi increased total phenol content of cookies. Total phenol content in 80% ethanol extract of muffins prepared with Korean wheat flour was 1.5 times higher than those made from imported wheat flour, whereas total phenol content was 1.2 times higher in the 80% methanol extract of baguettes prepared with imported wheat flour compared to those made with Korean wheat flour. Overall, total phenol content of Korean wheat flour was higher than that of imported wheat flour because total phenol content was higher in 80% ethanol extracts than in 80% methanol extracts. Antioxidant activity was not significantly different between ethyl acetate extracts of bakery products from imported wheat and Korean wheat, whereas antioxidant activity of 80% methanol extract of muffins with Korean wheat was 2.4 times higher than that from imported wheat. IVPD was not significantly different in any bakery products made from imported wheat or Korean wheat but was higher in baguettes than cookies or muffins. Conclusively, bakery products made from Korean wheat had higher total phenol content and antioxidant activity than imported wheat.
