Abstract:
Low-gluten flour,
Roxburgh rose juice, butter, sucrose and egg were taken as the raw materials, the color, flavor and texture were taken as the indicators of sensory test, the optimal of formulation of
Roxburgh rose cookies were investigated by the single factor experiments and response surface analysis. Results showed that, the optimal formulation of
Roxburgh rose cookies was as followings: The amounts of low-gluten flour,
Roxburgh rose juice, butter, sucrose and egg were 100%, 29.86%, 56.74%, 40.68% and 14.72%, respectively. The
Roxburgh rose cookies, which was produced by the above optimal formulation, had the uniform color, special sour flavor of
Roxburgh rose, moderate sweet. The
Roxburgh rose cookies achieved 89.31 scores in the sensory test. The drying loss, protein content, total lipid content, peroxide value, acid value of
Roxburgh rose cookies were 3.09%, 11.7 g/100 g, 26.2 g/100 g, 0.14 g/100 g, 1.4 mg/g, respectively. All the above indexes met the requirements of National Standard of China General Rules for Biscuit Quality (GB/T 20980-2021). Compared with the three famous commercial cookies, the hardness and acidity of
Roxburgh rose cookies were significantly higher (
P<0.05). The
