Abstract

The purpose of this study was to investigate the properties of frozen cookies containing buckwheat flour. Buckwheat flour was added to cake flour bases at concentrations of 3%, 6%, and 9%. Falling numbers, RVA (rapid visco analyzer) increased with the addition of buckwheat flour, whereas initial pasting temperature decreased. The set back value, which is a prediction of retrogradation, did not show any significant difference. The alveographic P values of the treatment were lower than that of the Control. In the farinogram test, water absorption increased upon the addition of buckwheat flour, whereas stability and farinogram quality number decreased. In conclusion, the addition of 6% buckwheat flour is recommended to obtain the optimal volume of frozen cookies.
