Effects of Roasted Soybean Flour on Textural Properties of Rice Cookies

چکیده
Changes in the textural properties of rice cookies as a result of using roasted soybean flour (RSF) as an additive were investigated in this study. RSF was replaced as 3, 6, 9, 12, 15 and 20% of 100 g of rice flour. The addition of RSF increased the hardness of dough and cookies as measured by texture analyzer (TA), whereas moisture content of dough and cookies decreased upon addition of RSF. Further, the addition of RSF led to an increase in the L value of dough and cookies, but to a decrease in the a and b values. In addition, the bulk density of cookies decreased upon addition of RSF, whereas bulk density of dough also declined when compared to control. The spreadability of cookies was found to be lower in comparison to control. The values of ∆bulk densities (BD) and ∆hardness of cookies also increased upon addition of RSF. From the point of view of sensory evaluation, addition of 9% RSF to rice cookies showed the highest score in terms of overall acceptability and softness. A 12% RSF addition to rice cookies led to the highest score in sandiness. As a result, we conclude that the crispy texture of the rice cookie can be improved by adding RSF.

Light buckwheat flour was used to substitute rice flour at the level of 10, 20 and 30% to produce gluten-free cookies. The substitution of gluten-free cookie formulation with light buckwheat flour contributed to the significantly higher mineral content, especially magnesium, potassium, iron and copper, in comparison with the control rice cookies (p<0.05). Gluten-free cookies made with rice flou...
