흑미가루 첨가비율(5-30%)에 따른 복합분의 이화학적 특성, 호화특성, mixograph 특성 및 스펀지 케이크의 제조적성을 측정하고, 이들 특성 간의 상관관계를 구명하고자 일련의 실험을 실시하였다. 흑미 가루 첨가량이 증가함에 따라서 alkaline water retention capacity, Pelshenke value, sedimentation value는 증가하였으나 water holding capacity는 감소하는 경향을 보였다. Mixograph peak time, height, width at peak와 Rapid Visco Analyser peak, minimum viscosity도 감소하였다. 스펀지 케이크 반죽의 pH와 비중은 증가하였지만 케이크의 부피는 감소하는 경향을 보였으며, 케이크의 경도는 증가하였다.

This study was conducted to evaluate the quality characteristics and antioxidant activities of rice flour sponge cakes containing 0, 20, 30, 40, and 50% Helianthus tuberosus powder (HTP). As HTP content of sponge cake increased, the pH of sponge cake batter significantly decreased, whereas specific gravity significantly increased (p<0.05). Meanwhile, volume and symmetry indices of sponge cake were inversely proportional to HTP amount. Further, with higher HTP content in sponge cake, L and b values of crumbs significantly decreased (p<0.05), whereas a value significantly increased (p<0.05). L, a, and b values of crust significantly increased with higher HTP content. For texture characteristics, hardness, cohesiveness, gumminess, and chewiness of sponge cake significantly increased (p<0.05),whereas cohesiveness did not significantly change. In the sensory evaluation test, rice sponge cake prepared with 10% HTP showed the highest sensory scores in terms of color, flavor, taste, softness properties, and overall preference. The levels of total polyphenol compounds and DPPH radical scavenging activities of rice sponge cakes significantly increased with higher HTP contents (p<0.05). The results of this study suggest that rice sponge cake containing 10% HTP is the most appropriate for quality characteristics and sensory evaluation. This study also provides a way to increase the quality, texture characteristics, and organoleptic properties of sponge cake while reducing HTP content to less than 10% in order to satisfy consumer tastes.

The aim of this study was to investigate the quality characteristics of sponge cakes with added rice flour produced by a modified genoise method to prevent volume reduction. A control group and experimental group I were prepared by the genoise method and experimental groups II, III, and IV were produced by a modified genoise method in which they were mixed with wheat flour and water to a make paste to form gluten for 3, 6, and 9 minutes, respectively. One third of the wheat flour in all experimental groups was replaced by rice flour. The control and experimental groups were compared in terms of quality characteristics, including batter specific gravity, volume, color, textural characteristics, and sensory qualities, to determine the optimal pasting time for wheat flour in the formulation. The specific gravity of the experimental groups was higher than that of the control and decreased with increasing wheat flour pasting time. The volume of experimental group I was lower than that of the control group, and the volume values of experimental groups III and IV, made by the modified genoise method, were higher than that of the control group. $dL^*$ and $db^*$values for the crust and inside of the cake were lower in the experimental groups than in the control. The $dL^*$ value, indicating brightness, increased as pasting time increased. The hardness values of experimental groups I and IV were higher than that of the control whereas experimental groups II and III had lower hardness values. Chewiness was higher in the control group, as well as experimental groups I and IV than in the experimental groups II and III. The gumminess of experimental group IV was highest. Cohesiveness decreased by adding rice flour to the sponge cake. Sensory attributes of cell uniformity, tenderness, moistness, taste, and overall acceptability had the highest scores in experimental group III. Based on these results, we conclude that the quality of sponge cake containing one third of the wheat flour replaced by rice flour is best with 6 minutes pasting of the wheat flour to form gluten.

The production of black rice in Korea has been increasing, as more Koreans are tending to blend black rice with medium-grain rice for serving. This increased production creates an opportunity for developing new products. In this study, the properties of sponge cakes produced from a blend of black rice flour (BRF) and wheat flour (WF) are investigated. Black rice sponge cakes (BRSC) were produced with constant process variables (e.g. baking temperature, fermentation time and BRP content (10, 20 & 30%)). Proximate compositions, farinogram, amylogram and extensogram analyses of BRSC were determined by AACC method. BRSC color was expressed to Hunter L, a and b values using a colorimeter. Sensory properties were evaluated by a trained 5-member panel. Moisture contents in BRSC decreased with increasing contents of BRF, while ash and protein contents were increased. Farinograph and amylograph data did not differ significantly between treatments, while extensograph data decreased with increasing BRF contents. With increasing BRF contents, Hunter L value decreased, while Hunter a value increased. When using 20% of BRP, sensory scores of BRSC were the highest in color, flavor and taste. In conclusion, 20% of BRF would be the optimum amount for producing sponge cake with BRP and WF.

This study investigated the effect of addition of pumpkin on the physicochemical properties of rice sponge cakes. Water retention capacity(WRC) was lowest in control preparations to which no pumpkin flour was added. WRC increased as more pumpkin flour was added and rice flour with 25% of added pumpkin flour showed a WRC of 89.0%. Similar to WRC, alkaline water retention capacity(AWRC) also increased as more pumpkin flour was added and ranged from 69.7% to 80.7%. As the amount of pumpkin flour added increased, the pH increased. Similar to the sedimentation value, the Pelshenke value also increased as the amount of the added pumpkin flour increased. The gelatinization temperature did not vary significantly between the samples(p<0.05). The midline peak height, which is the height of the peak point from the baseline, showed the same tendency with that of the midline peak time, but was not significantly different between samples(p<0.05). Volume was decreased as the amount of the added pumpkin flour increased. The weight of the rice sponge cakes showed significant difference increasing with the increasing added pumpkin flour(p<0.05). There was significant difference as the specific loaf volume decreased with the increasing pumpkin flour(p<0.05).

미분의 품종별(한강 찰벼, 추청 일반벼, 태백 통일벼), 제분 방법별(건식제분, 습식제분), 입도별(whole, 60mesh 이상, 100mesh 이상)등 미분의 특성이 스폰지 케이크의 제빵성에 미치는 영향을 조사하였다. $150^{\circ}C$에서 34분간 굽는 동안 반죽의 높이는 14~18분경 최대에 달했으며 그후 점차 감소하였다. 구운지 1일후 케이크의 높이는 반죽의 최대높이의 6~50%로 감소하였다. 굽는 과정중 반죽 내부의 온도는 서서히 증가하여 8~10분경 그 증가율이 가장 컸으며, 이때의 온도는 $60^{\circ}C$전후이었다. 100g의 반죽으로 만든 케이크의 체적은 제분 방법이나 미분의 입도에 따른 차이가 없이 밀가루로 만든 케이크 체적 100에 대하여 89~95로서 미분 100% 케이크 제조가 가능하였다. 한강의 체적은 80으로서 구운후 수축이 심하였다. 케이크의 경도는 미분의 종류, 미분의 입도에 무관하게 습식제분의 케이크가 건식제분의 것보다 낮았다. 태백의 건식제분 100mesh로 제조된 케이크의 경도와 응집성은 밀가루 스폰지 케이크에 근사하였다. 케이크의 관능검사 결과 texture나 맛면에서 전반적으로 건식제분보다는 습식제분의 케이크가 월등히 우수하였다. 특히, amylopectin 함량이 낮은 태백의 습식제분으로 제조된 케이크는 미분의 입도와는 관계없이 밀가루로 만든 것보다 관능평가 결과가 우수하였다.

The functional Jeungpyuns with dietary fiber containing cereals such as brown rice and barley flour were developed and physiochemical properties were investigated. The water binding capacity had significantly the highest value of 28.4% in raw rice flour, followed by brown rice flour and barley flour. The lowest reducing sugar value was seen in unpolished rice substituted Jeungpyun with value of 5.420 (P<0.05). The amount of reducing sugar decreased slightly after steaming, due to the increased degree of sugar dissociation. The L value of the lightness decreased significantly with the substituted samples (P< 0.05). The barley substituted samples were darker than that of brown rice sample groups with less green and yellow color. Microstructures of starch particles after fermentation showed completely dispersed starch particles with air bubbles and sponge-like structure in all samples after steaming. Thus, functional Jeungpyun replaced with brown rice and barley flour can be successfully formulated and has been influenced by the physicochemical properties.

The purpose of this study was to select an ingredient acting as a natural emulsifier to retard the retrogradation of rice cake by the measurement of mechanical characteristics of the cakes. For the purpose, Backsulgi, the most basic type of rice cake, was prepared by adding various ingredients having high contents of lecithin such as raw soybean powder, parched soybean powder, soybean oil, egg yolk powder, and the measurements and observations on the chromaticity, swelling power, pore ratio and cross-section were made. In addition, changes in the textural characteristics of Backsulgi samples were determined while storing them at the temperatures of 4$^{\circ}C$ and 20$^{\circ}C$ for 0, 1, 2 and 3 days. The results of the study were as follows: 1. In terms of chromaticity, the Backsulgi samples added with egg yolk powder, raw soybean flour and parched soybean flour were higher in yellowness(b) than the controls. 2. Both swelling power and pore ratio of Backsulgies added with raw soybean flour were higher than those of controls. 3. A cross-sectional observation using an electron microscope indicated that rice flour particles of controls had uneven pores and were conglomerated in a large lump while Backsulgi samples of raw soybean flour or roasted soybean flour had large and even pores and showed loosened bonding to be transformed into a sponge shape. 4. In hardness, Backsulgi samples added with raw soybean flour had less changes in hardness than that of controls, indicating that the effect of retarding retrogradation was higher when the storage time got longer.
