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.

This study examined the effects of chestnut powder content (2.5%, 5%, 7.5%, and 10%) on the antioxidant activity and quality characteristics of rice muffins. With the increasing chestnut powder content, the total polyphenol content, flavonoid content, antioxidant activity (determined by radical scavenging activity and reducing power), hardness, gumminess, chewiness, and overall acceptability (determined by sensory evaluation) increased, whereas the moisture content, pH, specific volume, and cooking loss decreased. Regarding color, chestnut powder content was negatively correlated with L and b and positively correlated with a. Notably, overall acceptability abruptly decreased to its minimum at 10%. Thus, adding powder at loadings of <7.5% improved the antioxidant activity and acceptability of rice muffins. Our results can be used as preparatory data for developing a rice muffin model.

The purpose of this study was to promote the consumption of rice by substituting goami powder for flour when making muffins. Goami powder was prepared in different particle sizes by grinding the powder for 5 min. 10 min. 15 min. and 20 min. Precisely 72.62% of the goami powder, particles were smaller than 75 ${\mu}m$, after grinding the powder for 20 min. with a consistency similar to that of flour (78.86%). To determine the optimal amount of water for goami powder muffin batter, the viscosity of both the flour and the goami powder batter was measured. The appropriate water quantity for goami powder muffins was set at 105 mL. The volume index of flour muffins was 132 mL, while that of the goami powder muffin (GM1, GM2, GM3 and GM4) was 123 mL, 119 mL, 119 mL and 118 mL, respectively. The hardness of the flour muffins, measured by a texture analyer, was 2.03${\times}10^3$ g/$cm^2$, The hardnesses of the goami powder muffins were 2.83${\times}10^3$ g/$cm^2$ for GM1, 2.44${\times}10^3$ g/$cm^2$for GM2, 2.33${\times}10^3$ g/$cm^2$ for GM3, and 2.36${\times}10^3$ g/$cm^2$ for GM4. The L-values and moisture content of the goami powder muffins were higher than those of the flour muffins. In a sensory evaluation the overall preference was the highest for flour muffins. However among the goami powder muffins, GM3, which was made with goami powder ground for 15 min. was the most preferred.

The effects of tigernut dietary fiber (TDF: 5, 10, and 20% w/w) inclusion in rice muffin formulations on the functional and pasting properties of composite powders, as well as the nutritional and sensory properties of muffins were investigated. The results showed a significant (p<0.05) proportional increase in the water and oil holding capacity as TDF increased in the powder blends. Moreover, pasting viscosity was found to decrease with the inclusion of TDF. TDF muffins showed improved nutritional quality, with increased protein (~14%), insoluble fiber (~128%) and total fiber (~34%) contents compared to 100% rice muffins. Also, TDF-muffins had lower baking losses (~22%) and better texture, including firmness and chewiness. Sensory scores of TDF-muffins (up to 10% w/w) showed similar consumer acceptability for all parameters considered. Overall, this study suggests tigernut fiber as a functional additive that balances the growing consumers' demands for healthy and quality gluten-free rice muffins.
