Purpose: This study was to determine the optimal composite recipe of rice cookie with 3 concentrations of Spergularia Marina L. Griseb, sugar and grape seed oil, using central composite design (CCD). Methods: The mixing condition of rice cookie was optimized by subjecting it to sensory evaluation and mechanical and physicochemical analysis using response surface methodology (RSM). Results: The results of mechanical and physicochemical analysis showed significant values for lightness, redness, yellowness, hardness, spread factor, loss rate, leavening rate, density, pH, moisture, sweetness and saltiness (p<0.05), and the results of sensory evaluation showed significant values for color, flavor, taste, texture, appearance and overall quality (p<0.05). As a result, the optimal sensory ratio was found to be 6.40 g of Spergularia Marina L. Griseb, 63.49 g of sugar and 106.19 g of grape seed oil. Conclusion: In conclusion, Spergularia Marina L. Griseb is a good source in natural antioxidant aimed at replacing salt, and it is possible to use in cookie or other food products to substitute salt.

This study was conducted to find out the bakery processing suitability of maca and to develop rice-based processed foods. We investigated the antioxidant activity and physicochemical properties of rice cookies prepared with the addition of maca (Lepidium meyenii) powder (1%, 2%, 3%, and 4% of the total materials). We observed an increase in the total polyphenol and flavonoid content, and DPPH-ABTS⁺ radical scavenging activity of the rice cookies as the proportion of added maca powder increased (p<0.05). The quality characteristics such as the "a" value, "b" value, and the hardness of the cookies increased with an increase in the proportion of maca powder (p<0.05) in the cookie, whereas the moisture content, pH of the dough, spread ratio, loss rate, leavening rate, and "L" values showed a significant decrease (p<0.05). In the sensory evaluation results, consumer acceptability showed a significantly higher value in the 2% maca cookie group (p<0.05), and the characteristic intensity rating (color, flavor, bitterness) increased as the proportion of maca added to the cookie increased (p<0.05). Therefore, this suggests that adding 2% maca powder as the functional ingredient in rice cookies can result in rice bakery products with excellent qualities.

This study was conducted to develop a recipe for a nutritional cookie containing chungkukjang powder that had a composition of ingredients and a texture that resulted in a high preference by all age groups. Wheat flour was partially substituted with chungkukjang powder to reduce its content. Response surface methodology was then used to analyze the measured results, which showed 16 experimental points including 2 replicates for chungkukjang powder, butter and sugar. The compositional and functional properties were then measured, after which these values were applied to a mathematical model. A canonical form and perturbation plot revealed the influence of each ingredient on the final mixture. The results of the sensory evaluation showed significant values with respect to color (p<0.01), texture (p<0.05) and overall quality (p<0.05). Taken together, the results of this study indicated that the optimal ratio was 26.57 g of chungkukjang powder, and 82.08 g of butter for every 52.36 g of sugar. The physical and chemical sensory measurements were then evaluated by a t-test, and the results revealed significant differences in the flavor of the optimized cookie when compared to the control cookie.

This study was conducted to evaluate the quality characteristics and the hypoglycemic effect of cookies containing Helianthus tuberosus powder (HTP). To examine the effect of adding HTP, cookies with various HTP contents (0%, 10%, 20%, 30%, 40%) were made and compared for their quality characteristics. The pH of cookie doughs decreased significantly (p<0.05) as the content of HTP increased. However, the density did not show significant difference among samples. The spread ratio and loss rate in cookies showed significant increase (p<0.05) as the content of HTP increased. However the leavening rate and the hardness of the cookies decreased significantly (p<0.05) when HTP content increased. Color measurement also showed significant difference among samples, although the cookie sample with 10% HTP powder showed the highest scores from consumer tests and liking score, the cookie samples with 30% HTP were selected to measure the hypoglycemic effect of Helianthus tuberosus compared to control cookies and bread. Ten healthy subjects in their twenties participated in measuring blood glucose levels after intake of bread, control cookie, or 30% HTP cookie. Blood glucose level was measured after fasting 12 hours, before eating, and 30, 60, 90, and 120 minutes after taking the samples. As a result, the blood glucose levels at 30min after meals showed significant (p<0.05) difference among treatments: the lowest when taken the cookies added 30% HTP. However there was no difference in the blood glucose levels at 60min, 90min, and 120min after the sampling.

This study was conducted to evaluate sensory properties of sugar cookie containing sucralose. Relative sweetness of sucralose to sucrose in a cookie system was examined with paired comparison tests and the result was applied to low calorie cookie preparation using polydextrose as a bulking agent. Physical and sensory properties and consumer acceptability of sugar cookies containing various levels of sucralose and polydextrose were evaluated. Relative sweetness of sucralose to sucrose was 700 times in sugar cookie. Instrumental hardness and fracturability increased as the levels of replacement with sucralose increased. Spread ratios of sugar cookies where sucrose was partially and totally replaced with sucralose and corresponding amount of polydextrose were higher than that with sucrose only. Intensities of bitter taste, salty taste, hardness and molar packing of sugar cookies where sucrose was entirely replaced with sucralose and polydextrose were higher than that those of the other cookies. Acceptability test indicated 75% replacement with sucralose and adequate amount of polydextrose can be used without harming overall, appearance and flavor acceptability while texture acceptability was slightly lower.

과당의 이성체인 알룰로오스가 저혈당 및 저칼로리효과를 갖는 건강쿠키를 제조하는데 설탕대체제로 이용이 될 수 있는지 평가하였다. 설탕(대조군), 과당, 포도당, 알룰로오스를 사용하여 이들 설탕대체제들의 효과를 SRC, DSC, RVA, 와이어 컷 쿠키 방법으로 평가하였다. SRC 결과에서 용액에 접근 가능한(solvent-accessible) 아라비노자일란이 다른 당용액에 비해 알룰로오스에서 가장 적게 부푸는 것으로 관찰되었다. DSC와 RVA 결과들에서 각각 밀가루 전분의 호화 및 전분 pasting의 개시가 모두 물 < 알룰로오스 < 과당 < 포도당 < 설탕의 순서로 지연됨을 알 수 있었다. 사용한 당 중에서 포도당으로 만든 쿠키가 지름과 두께 측면에서 가장 선호되지 않는 특성을 나타냈다. 알룰로오스의 쿠키 베이킹 적성은 설탕에 비해 조금은 부족하지만 과당보다는 뛰어나 과당대 체제로나 설탕대체제로 저칼로리 저혈당효과가 있는 쿠키를 제조하는데 성공적으로 이용될 수 있음을 시사하였다.

Photostimulated luminescence (PSL) and thermoluminescence (TL) analyses were applied to identify the cookie molds mixed with 2 mg of 10 kGy-irradiated minerals according to cookie processing methods and sonication time (0~60 min) for mineral separation. PSL analysis showed that photon counts of cookies, dried or baked, ranged intermediate levels between the lower and upper threshold (700~5,000 counts/60 s), thereby showing its unsuitablility for screening of irradiated cookie. The TL glow curve intensities, measured according to mineral separation time (5, 10, 20, 40 and 60 mins) from the cookies using a sonicator, were high enough to identify irradiation status and significantly increased with the time in dried cookies. Those of baked cookies, however, were relatively low and not linearly increased with the time, but still possible to identify them (p<0.05).

End-use properties of six Korean waxy wheat lines and their parental plants were evaluated in this study. Korean waxy wheat lines showed unsuitable characteristics for end products, such as sticky crumb of bread, sticky cooked wet and dry noodles and small cookie diameter. Korean waxy wheat lines produced lower loaf volume and less desirable crumb grain structure of bread, and lower chewiness of cooked wet and dry noodles than their parental plants even though Korean waxy wheats were much higher in protein content and SDS-sedimentation volume than their parental plants. We observed adverse effects of high flour protein content in Korean waxy wheat lines, such as smaller cookie diameter and harder snapping force than those produced from their parental plants.
