This study was conducted to develop a recipe for a nutritional cookie containing Danggue powder, and to achieve an optimal ingredient composition and texture that would appeal to consumers of all ages. To reduce its content, wheat flour was partially substituted with Danggue in the formulation. Response surface methodology was used to analyze the measured results and showed 16 experimental points, including 2 replicates for the Danggue powder, brown sugar, and butter ingredients. The compositional and functional properties were measured, and these values were applied to a mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the final product. The sensory evaluation results indicated significant differences between samples for color (p<0.01), flavor (p<0.01), texture (p<0.05), and overall quality (p<0.05). As a result, the optimal ingredient levels for sensory quality were determined as 4.83 g of Danggue powder, 70.46 g of brown sugar, and 86.08 g of butter.

The aim of this study was to develop rice cookies based on 'Goami 2' rice, and made with sesame (white and black) and perilla seeds. Furthermore, we studied the physicochemical and sensory characteristics of the cookies as well as the alternative effects of the sesames or perilla seeds for butter, where we substituted the sesames or perilla for 30% of the total butter. The pH values of the cookie doughs made with the sesames or perilla seeds were significantly different (p<0.001), whereas the spread factors of the doughs were not significantly different. The Hunter color L-, a-, and b- values were significantly different for the cookies made with the added sesames or perilla seeds (p<0.001). The brittleness of the Goami 2 rice cookies (control) was significantly higher than that of the cookies made with the sesames or perilla (p<0.001). In a descriptive analysis performed by 8 trained panelists, the following sensory characteristics: yellow, black, sweet taste, nutty taste, nutty odor, oily flavor, and off flavor, were significantly different among the cookie samples. In a consumer test by 50 women students, the Goami 2 rice cookies were preferred in the following order: Goami 2 rice cookies with no additions > black sesame cookies > white sesame cookies > perilla cookies. In conclusion, some physicochemical and sensory characteristics of the cookies were different, in relation to being made with or without the sesame or perilla seeds. However, because of the small difference in acceptance among the cookies, the sesame and perilla rice cookies show strong potentials for consumer acceptance. Moreover, the black sesame cookies were more acceptable in terms of butter substitution for the cookie preparation.

This study was performed to determine the optimal manufacturing conditions of cookies prepared with Hizikia fusiformis. The variables in Hizikia fusiformis cookies production were the amounts of Hizikia fusiformis powder, butter, and sugar. Six sensory characteristics were used for sensory evaluations, including color, appearance, taste, brittleness, hardness, and overall acceptability. The optimal amounts of the three variables were found to be 6.00 g for Hizikia fusiformis powder, 100.00 g for butter, and 70.00 g for sugar against flour powder 200 g, which satisfies a target sensory score (7.0/9.0) according to the response surface method. Cookies with these optimal amounts of Hizikia fusiformis powder, butter, and sugar were tasted by 114 consumers and showed a high acceptability score (7.21). Females preferred the flavor of Hizikia fusiformis significantly more than males did (p<0.05). Older consumers (${\geq}30$ years old) scored significantly higher than younger consumers (${\leq}29$ years old) in texture (p<0.05). Spread ratio and hardness scores of Hizikia fusiformis cookies were lower than those of control cookies. Color analysis results of Hizikia fusiformis cookies were significantly lower in brightness and redness, and higher in yellowness than control cookies (p<0.01).

This study was conducted to develop an optimal composite recipe of nutritional cookies containing Chinese artichoke (Stachy sieboldii Miq) powder. Rice powder was partially substituted with Chinese artichoke (Stachy sieboldii Miq) powder to reduce its content. The optimal sensory composite recipe was determined by 3 concentrations of Chinese artichoke (Stachy sieboldii Miq) powder, butter, and sugar, using the central composite design. In addition, the mixing condition of Chinese artichoke (Stachy sieboldii Miq) powder rice cookies was optimized by subjecting the cookies to a sensory evaluation and instrumental analysis using the response surface methodology (RSM). The effects of the addition of the three variables on the quality of Chinese artichoke (Stachy sieboldii Miq) rice powder cookies were assessed in terms of color, hardness, sweetness and sensory evaluation. The results of the sensory evaluation produced values very significant for flavor, texture, sweetness, appearance, and overall quality (p<0.05). The results of instrumental analysis showed significant values in moisture content, spreadability, sweetness (p<0.01), lightness, redness, and hardness (p<0.001).
