In this study, muffins containing Bokbunja, popularly known as a psychological activator and functional material, was made, and its preference levels and qualitative characteristics were evaluated. We measured the height and weight of muffins containing Bokbunja powder. Height decreased when the volume of Bokbunja powder increased (p<0.001). When weight was measured, there was no meaningful difference between the samples, although the Bokbunja powder-containing samples were heavier than the samples not containing Bokbunja powder. When we measured the weight and specific volume of the muffins containing Bokbunja powder, the specific volume decreased when the amount of Bokbunja powder increased (p<0.001). The moisture and pH levels of the muffins not containing Bokbunja powder were 17.04% and pH 8.59, respectively. As the volume of Bokbunja powder increased, the moisture level of Bokbunja muffin increased while the pH decreased, and there was a significant difference (p<0.001). As a result of measuring the colors of muffins, the brightness of the muffins containing Bokbunja powder decreased, and the muffins showed decreased yellowness index and increased redness. In measuring the texture of Bokbunja muffins, hardness decreased as the volume of Bokbunja power increased (p<0.001). Further, springness of the muffins decreased as the volume of Bokbunja powder increased, and there was a significant difference (p<0.001). The chewiness of the muffins not containing Bokbunja powder was higher than any other muffin sample, and there was a significant difference between the samples (p<0.001). Further, the cohesiveness of the decreased as the volume of Bokbunja powder increased (p<0.001). Bokbunja muffins showed a lower gumminess index than those not containing Bokbunja powder (p< 0.05). When the sensual qualities of the muffins were measured, the color, flavor, taste, and softness of all of the samples showed significant differences (p<0.001), and the muffins containing 8% Bokbunja powder showed the highest sensual quality indexes. When the general preference level for the muffins was measured, the muffins containing 8% Bokbunja powder showed the highest index, 7.03${\pm}$0.96. Based on this result, the ideal volume of Bokbunja powder when making muffins is 8%.

The purpose of this study was to examine the qualities of muffins with 20, 40, and 60% brown rice flour (BRF). The muffins containing 20, 40, and 60% BRF were lower than control muffins (made with regular flour) in weight, height, pH, and moisture content. No significant differences were observed between BRF muffins in weight and moisture content; however, height and pH decreased with increasing amounts of BRF added (p<0.05). The moisture content of control muffins decreased after storage at $30^{\circ}C$ and was not significantly different than BRF muffins (p>0.05). The hardness and resilience in the controls were higher than BRF muffins, but increasing the amount of BRF added in muffins increased both hardness and resilience (p<0.05). The cohesiveness and springiness in the controls were higher than in BRF muffins and decreased with increasing the amount of BRF added to muffins (p<0.05). The gumminess and chewiness in muffins with BRF were higher than controls and were increased when the amount of BRF added in muffins was increased (p<0.05). However, the adhesiveness of the samples was not significantly different (p>0.05). In sensory evaluation, the external color in muffins with 20% BRF and the internal color in controls were the highest (p<0.05). The taste, aroma, texture, and overall acceptability were the highest in muffins with 60% BRF (p<0.05). The antioxidant activities, DPPH radical scavenging, and superoxide dismutase-like activity of muffins were increased with increasing the amount of BRF added to muffins (p<0.05).

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.

In this study, the approximate compositions, color properties, texture properties, physical characteristics, and sensory evaluation of muffins prepared from legumes (mung bean, cowpea, chickpea, or lentil) and wheat flour blends was evaluated. Pasting viscosity of legume flours was lower than that of wheat flour. The moisture, crude ash, and crude protein content of muffins made with legume-wheat flour blends were higher than those of control muffins made exclusively with wheat flour. The lightness value of muffins was decreased by adding legume flour. The hardness of muffins made from legume-wheat flour blends was higher than that of control, whereas springiness and cohesiveness was lower. The weight of muffins made with legume-wheat flour blends were higher than that of control, whereas the height and volume were lower than those of control. The scores of taste, aroma, and texture of muffins were not significantly changed by adding legume flours. The overall acceptability of muffins that were made with lentil or chickpea flour was similar to that of control muffins.

The principal objective of this study was to determine the optimal conditions for making muffins with sea-tangle powder, which is known to be a healthy food supplement. The characteristics of the sea-tangle muffins were analyzed in a quality evaluation. Sea-tangle powder was added to the muffins at concentrations of 0%, 5%, 10%, 15%, 20% prior to baking. The height of the muffins to which the sea-tangle powder had been added, after storage at $20^{\circ}C$, was shown to decrease with increases in the concentration of sea-tangle powder. The weight of the muffins increased with increasing storage time, but these differences were not profound. The moisture content of the muffins decreased with increased storage time. The change in pH in accordance with storage time differed only slightly. In terms of the color of the sea-tangle powder-supplemented muffins, after storage at $20^{\circ}C$, the “L” and “b” values decreased with increasing amounts of added sea-tangle powder. The “a” value increased with increasing amounts of added sea-tangle powder. With regard to the textural properties of the sea-tangle powder-supplemented muffins, after storage at $20^{\circ}C$, the hardness and chewiness increased with greater quantities of added sea-tangle powder. Springness, cohesiveness, and adhesiveness differed only slightly as more sea-tangle powder was added. With regard to the sensory characteristics of the muffins, the overall quality of the muffin to which 10% sea-tangle powder was added was evaluated as the best. The color, flavor, and softness were also assessed as the highest. The sweetness of the muffins was assessed as weak.

The quality characteristics of muffins prepared with hesperetin (0.2, 0.4 or 0.8%), a flavonoid, were evaluated. There were no significant differences in volumes and heights of the muffins due to the various additions of hesperetin, or in the L, a and b values of the crust and crumb of the various muffin groups. The sweetness of the muffins containing the highest level of hesperetin (0.8%) gave the highest scores in the sensory test. A stepwise regression analysis showed the sweetness and after taste were the significant factors affecting the overall preference for the muffins. Therefore, hesperetin may be useful as a muffin additive as its addition did not impair the sensory characteristics of the muffins.

This study investigated the quality of muffins prepared with various concentrations of mealworm. Samples of muffins were prepared with the addition of 0, 1, 2, 4, 6 and 8% mealworm powder to the flour of basic formulation. The weight of muffins decreased as the concentration of the mealworm powder increased. The height indices of muffins containing mealworm powder were higher than that of the control. The volume index of the MW2(2%) muffin was the highest. The pH of muffins containing mealworm powder was higher than that of the control, although moisture content lower. Lightness and yellowness decreased with an increase in the mealworm powder concentration, but redness increased. No significant difference in hardness was found from increased powder concentration. The total polyphenol content and antioxidative activity measured by 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of muffins significantly increased as the concentration of the mealworm powder increased. Muffins containing 1~8% mealworm powder had acceptable sensory properties, such as flavor, taste, and overall acceptability. The results of this study suggest that mealworm powder is a good ingredient for consumer acceptability and functionality of muffins.

This study was conducted to examine the applicability of muffins and the optimal ratio of batter mixture by adding mugwort with various functions and physiological active substances. In result of examining the quality characteristics of muffins after adding frozen-dried mugwort powder by 0%, 1%, 3%, 5%, or 7%, the moisture retaining capacity of muffin batter was lowest with MPM0, the control group, and the deposition was highest at $17.94m{\ell}$ with MPM0. The pH value of muffin batter was highest at 8.62 with MPM0 and moisture decreased significantly (p<0.001) when more mugwort powder was added to the sample. The brightness increased significantly (p<0.001) when the amount of frozen-dried mugwort powder decreased and redness and yellowness decreased when the addition of mugwort powder increased. The height and volume of mugwort muffins were lowest at 4.75 cm and $135.69m{\ell}$ with MPM7 with the greatest value of frozen-dried mugwort powder. The loss at baking of mugwort muffins was lowest at 2.27% with MPM7. The hardness of mugwort muffins was highest with MPM7 with the highest mugwort powder content. Coagulation and resilience was highest at 0.64 with the MPM0 control group and the chewiness increased significantly (p<0.001) with greater amount of frozen-dried mugwort powder. The appearance of mugwort muffins was highest at 6.1 with MPM5 and the most preferable color and flavors were found with MPM3. Tenderness was highest with the MPM0 control group. Overall preferability was highest with MPM3 with 3% frozen-dried mugwort powder. When adding frozen-dried mugwort powder to muffins, the 3% and control groups mostly showed the highest values, whereas the 5% group and higher groups showed lower values.

The purpose of this study was to examine the qualities of muffins with 0, 3, 6, 9, and 12% bitter melon powder. The specific gravity of muffins prepared by adding bitter melon powder was higher than that of the control group. The height of the control group was higher than that of the samples with bitter melon powder. The weight of muffins was not significantly different between all sample groups. The volume and specific loaf volume of muffins were decreased by the addition of bitter melon powder. The baking loss rate of muffins was not significantly different between all sample groups. The moisture content of the samples with bitter melon powder was higher but the pH of muffins was lower than those of the control group. DPPH radical scavenging activity of the control group was 26.86%, whereas the samples with bitter melon powder ranged from 41.35~74.91%. In crumb color, the L value was decreased, but a and b value were increased significantly by the addition of bitter melon powder. The hardness, springiness, cohesiveness, chewiness and brittleness of textural properties of muffins were significantly decreased by the addition of bitter melon powder. Sensory evaluation scores in terms of appearance, flavor, taste, texture and overall preference of groups with 3% and 6% of bitter melon powder did not show any significant difference when compared to the control group. Based on the above results, using less than 6% of the bitter melon powder would be proper to make muffins.
