The aim of this study was to improve rice muffin quality with sorbitol using response surface methodology(RSM). Response surface experimental design was made by central composite design using several independent factors. In preliminary experiment of chlorella rice muffin, rice flour(RF), chlorella(CH) and sorbitol(SO) were chosen as independent factors. Response factor was the overall acceptability obtained from sensory evaluation. The regression model equation could be predicted as $OV=6.70-0.45CH-0.44RF^2-0.81CH^2-0.60SO^2$. The optimal conditions for chlorella rice muffin substituted with sorbitol were determined to be 60.8% of RF, 4.7% of CH and 35.45% of SO. Rice muffin was superior to flour muffin in sensory evaluation using the prediction value derived from RSM. Therefore, the optimum condition of muffin could be developed by RSM.

This study was performed to compare the processing aptitudes of the rice muffins produced from the seven rice varieties, including Goami, Goami 2, Deuraechan, Baegjinju, Seolgaeng, Haiami and Hanareum, along with the use of hydroxypropyl methylcelluloses (HPMCs) as a replacement for the egg white. The water binding capacity of rice flours was significantly higher than that of wheat flour, but its fat binding capacity was lower than that of wheat flour (p<0.05). In the viscosity of the batter, Goami and Baegjinju were lower than that of the wheat flour. There was no significant difference in the specific gravity of Seolgaeng and the batter of wheat flour. The pH of all varieties except Goami 2 was higher than batter of wheat flour(p<0.05). Haiami flour produced higher muffin volume and specific volume compared with the wheat flour muffin. The textural characteristics, the muffins produced by Haiami and Hanareum flours had significantly lower hardness than the wheat flour muffin after 30 hours. All rice varieties except Gaomi 2 showed no significant difference compared to the wheat flour muffin in color, taste and texture (p<0.05). Furthermore, flavor of muffins produced from the Seolgaeng, Haiami and Hanareum flours tested higher than the wheat flour muffin. It was concluded that the rice varieties of Seolgaeng, Goami, Haiami and Hanareum were considered to be the most suitable rice cultivars for the rice muffins.

The purpose of this study was to determine the optimal composite recipe of rice muffin using three different amounts of Chinese artichoke (Stachys sieboldii MIQ) powder, brown sugar, and egg. Response surface methodology (RSM) was used to obtain 16 experimental points (including three replicates of Chinese artichoke powder, brown sugar, and egg), and the Chinese artichoke rice muffin formulation was optimized using rheology. The results of the sensory evaluation showed very significant values for color, texture, sweetness, and overall quality (P<0.05). The results of the color, texture, and chemical analyses showed significant values for crumb redness (P<0.01), crumb yellowness (P<0.05), crust redness (P<0.05), crust yellowness (P<0.001), crust lightness (P<0.05), adhesiveness (P<0.01), springiness (P<0.001), gumminess (P<0.01), cohesiveness (P<0.05), moisture content (P<0.05), and sweetness (P<0.05). As a result, optimum formulations obtained by numerical and graphical methods were found to be 8.28 g of Chinese artichoke powder, 66.20 g of brown sugar, 111.72 g of sticky rice powder, 30 g of rice powder, and 59.37 g of egg.

We examined the quality characteristics and conducted a sensory evaluation of muffins made with rice flour and the biopolymer hydroxyethyl methylcellulose (HEMC) to identify a new health functional food additive. First, overrun and foam stability of HEMC-HV (high viscosity) was better than HEMC-LV (low viscosity) to prepare muffins. Also the quality of rice muffins(volume, specific cake volume, and baking loss) was analyzed. There was no significant difference in the sensory evaluation of rice flour muffins containing foam mixture(egg white:HEMC-HV, 3:1, v/v) and muffin made from flour. The results showed that HEMC-HV was suitable for quick bread muffin-making using 100% rice flour.

Muffins were prepared with different amounts of rice bran powder (0~30%), and their quality characteristics were investigated. The specific gravity of batters increased with increasing rice bran. While the initial pasting temperature increased with increasing rice bran amount, peak viscosity and viscosity at $95^{\circ}C$ after 15 min gradually decreased. The pH value of batters and muffins decreased with increasing rice bran amount. Moisture content of muffins was affected by the addition of rice bran powder. The lightness and yellowness values of muffins decreased with increasing rice bran amount, whereas redness value increased. For textural characteristics, hardness, gumminess and chewiness of muffins significantly increased with increasing rice bran amount, whereas cohesiveness and springiness decreased. Aircell uniformity of muffins became larger and more random as rice bran powder content increased. In the sensory evaluation, scores of taste and texture were the highest in muffin added with 5% rice bran powder. Overall acceptability was highest in control and the 5% group without any significant difference. Values of color, flavor, taste, texture and overall acceptability of muffins tended to decrease as rice bran powder content increased.

The purpose of this study was to bake sweet rice muffins with oak mushroom ($Lentinus$ $edodes$) powder. The process included substituting sweet rice flour for cake flour and adding oak mushroom powder. This study determined the optimal mixing conditions of oak mushroom muffins by adjusting the amounts of oak mushroom powder, whole eggs, and soybean oil. The mixing conditions for the oak mushroom muffins included 3 categories: oak mushroom powder (X1), whole eggs (X2), and soybean oil (X3) by Central Composite Design (CCD) which was optimized by Response Surface Methodology (RSM). Oak mushroom muffin formulation was optimized using rheology. Yellowness (p<0.001) and redness (p<0.05) displayed a linear model pattern, whereas lightness (p<0.05) was represented by a quadratic model. Among the sensory properties, variables that appeared to show significant values such as appearance (p<0.5), texture (p<0.5), and overall quality (p<0.5) were used to identify optimums. The result of mechanical properties showed significant values in gumminess (p<0.5) and chewiness (p<0.5). The numerical and graphical methods used in this study determined that the optimum formulation for oak mushroom powder sweet rice muffins was 8.75 g of oak mushroom powder, 235.95 g of whole eggs, and 19.93 g of soybean oil.

This study was undertaken to optimize preparation of sweet rice muffins using lotus (Nelumbo nucifera Gaertn) seed powder. The experimental conditions used in the preparation included lotus seed powder (X₁) and soybean oil (X₂). The muffin formulation was optimized using rheology. Lightness (P<0.01) displayed a quadratic model pattern, whereas yellowness (P<0.01) and redness (P<0.05) was presented a linear model. Texture properties significantly differed in cohesiveness (P<0.05). Evaluating the sensory characteristics of muffins, except for flavor and texture, the remaining properties of color (P<0.01), taste, overall quality, and appearance (P<0.05) were found to be significantly different. The overall quality was also affected by the proportion of lotus seed powder, rather than the amount of soybean oil. The optimal ratio for palatability of muffins was determined to be 47.80 g lotus seed powder and 95.28 g soybean oil. Taken together, our results indicate that sweet rice muffins prepared using lotus seed powder are sufficiently competitive in terms of function and quality.
