Edible insects, such as the two-spotted cricket (Gryllus bimaculatus, GB), have high nutritional value but are not widely consumed because of their appearance and smell. Consequently, the development of foods containing these insects in less recognizable forms, e.g., flour-like powders, has drawn considerable attention. Herein, we investigated the quality characteristics of muffins prepared from wheat flower supplemented with fresh ginseng (5%) and GB (0, 10, 20, and 40%) powders. GB loading was negatively correlated with muffin volume, height, moisture content, and textural properties (hardness, springiness, cohesiveness, and chewiness) and positively correlated with crude protein content and antioxidant properties. Significant (p<0.05) color differences were observed between samples with different GB loadings. The contents of hexanal and nonanal, which are the major volatiles responsible for off-flavor, increased with increasing GB loading, and the number of volatiles maximized at 40% GB. Sensory preference decreased in the order of 0% GB>10% GB≈ 20% GB>40% GB. Based on these results, a GB loading of 20% offered the best trade-off between attractiveness and nutritional value. Thus, this study promotes the widespread use of GB in the food industry and the development of various edible-insect-based food products.

This study was conducted to develop functional muffin in which grape seed extract(GSE) was added at 0, 0.5, 1 or 2% levels and to evaluate the quality characteristics. The volume of muffin decreased with the increasing GSE content, but no significant differences were observed. The weight and height of muffins increased with the increasing GSE content. The incorporation of GSE in the product lowered lightness (L value) and increased redness(a value). The mechanical texture parameters including hardness, springiness, gumminess and brittleness increased with the increasing GSE levels. Sensory analysis showed that muffin prepared with 0.5% GSE was considered to be as acceptable as control, based on hedonic scale ratings given by untrained taste panel.

The purpose of this study was to develop a muffin recipe that included germinated brown rice powder soaked in a mycelial culture broth of Phellinus linteus (GBRP). Muffins were made using various quantities of GBRP, butter, and milk. An assessment was conducted using the response surface methodology (RSM), which included 16 experimental points with three replicates for the three independent variables: GBRP, butter, and milk. The physical and chemical evaluation using the RSM showed no significant differences; whereas the hardness, cohesiveness, springiness, gumminess, and chewiness indicated significant differences in the relationships between the factors (p<0.05). The sensory evaluation using the RSM was highly effective in describing the relationships between overall acceptability and taste (p<0.001). Thus, the optimal combination of ingredients in a GBRP muffin, as assessed with numerical and graphical methods, was 84.041 g GBRP, 110.224 g butter, and 80.0 g milk.

Moisture content of muffin tended to increased as increasing mixing rate of maesangi. For crude protein, sample group of 9% replaced by maesangi powder was the highest. For crude fat and crude ash, there was no significant difference among sample groups. The average height of muffin was 4.7 cm, but was no significant difference among sample groups. Volume of muffin has been gradually increased as increasing mixing rate of maesangi powder, but was no significant difference among sample groups. From the SEM (scanning electron microscope) result, thick cell wall and rough blowholes were appeared. L-, a and b-values of muffin was declined as per increase of mixing rate of maesangi powder. Hardness was inclined as per increase of mixing rate of maesangi powder. There were significant differences between sample groups and reference group for adhesiveness, springiness and cohesiveness, but was no significant difference among sample groups. For gumminess, sample group of 9% replaced by maesangi powder was the highest, but there were no significant difference from sample groups of 3% and 6% replaced by maesangi powder. Chewiness was inclined as per increase of mixing rate of maesangi powder, and sample group of 9% replaced by maesangi powder was the highest. From sensory test result, sample group of 9% replaced by maesangi powder was the highest for color, and there were significant differences among sample groups. Sample group of 6% replaced by maesangi powder was the highest for flavor and taste, and there were significant differences among sample groups. Sample groups of 6% and 9% replaced by maesangi powder were the highest for texture. Sample group of 9% replaced by maesangi powder was the highest for overall preference. From all these results, the most suitable one would be the sample group of 9% replaced by maesangi powder.

Recipes for cookies and muffins made with soybean paste and sun-dried salt were established and characteristics of the foods were investigated. On Hunter's color scale, 'L' values decreased and brightness was lowered as additive levels increased, whereas the 'a' value(redness) increased and the 'b' value(yellowness) decreased. The hardness of a control muffin was 1843 g and this increased as additive levels rose. Cookies showed the same tendency. Elasticity was not proportional to paste content whereas crispness increased as additive levels increased. Sensory evaluations of cookies and muffins with different soybean paste contents(0-8%, w/v) showed that additive at 1% (w/v) was best and additive at 8%(w/v) was unacceptable. All products scored poorly 48 h after preparation; freshness needs to be investigated further.

Premature-green wheat is typically obtained by early harvest when culms of wheat still appear green in color, and the wheat and its food products have been considered as wellbeing foods. The pasting properties of prematured whole green wheat powder (WGWP), were analyzed with a rapid viscosity analyzer (RVA), and compared with commercial flours. The RVA values of lower peak viscosity and time, holding strength, final viscosity, as well as breakdown and setback viscosity showed that the WGWP could retard a gelatination of starch and also delay retrogradation in bakery products. WGWP with different levels of 10, 20, 30 or 50% was added into flours for preparing bakery product (bread, muffin and cookie), and their quality properties were evaluated. The addition of WGWP lead to a reduction in loaf volume of bread and muffin, and bakery products containing different levels of WGWP showed the changed internal surface structure (e.g. pore size) observed with a scanning electron microscope when compared with the control (0% WGWP). The hardness, gumminess, chewiness of bread and muffins were increased, and cohesiveness was decreased as the WGWP content increased, but the hardness of cookies was decreased. The bakery products added WGWP showed darker and more greenish and yellowish color than control (p<0.05). The sensory evaluation showed that bakeries with WGWP were scored to have more greenish taste and green color (p<0.05), and muffins and cookies with WGWP were evaluated to have more nutty and less oily taste (p<0.05).

This study investigated the quality characteristics of the muffins with garlic paste. Four different paste concentration levels of 0, 40, 80 and 120g were added to 200g flour to make the muffin. In terms of color, the lightness and yellowness of the muffin increased and redness decreased with increasing amounts of garlic paste. Among the textural characteristics hardness, springness, cohesiveness, gumminess and chewiness were increased according to the addition level of garlic paste. However, there were no significant differences in hardness and springness of the muffin. For the sensory evaluation, appearance, flavor, taste and texture of the muffin was not significantly different than the control group. The appearance, taste, texture and overall acceptability were excellent in the group with the addition of 40g garlic paste. From the results of this study, the muffin with 40g garlic paste added content was shown to have the best quality.

The effects of phytase and cellulase treatment on the bioavailability of iron, calcium, and zinc in whole wheat flour and their food applications were evaluated in this study. Whole wheat flour was treated with phytase and cellulase either individually or in combination and incubated at 50℃ for 2 h; the concentrations used for the individual enzymes were 2%, 10%, and 20%. The concentration of the combination enzyme was 20% with a mixing ratio of 5:5. Total dietary fiber and phytate contents were reduced as the concentrations of phytase and cellulase increased. The bioavailability of iron, calcium, and zinc was notably improved after in vitro digestion in 20% cellulase, combination enzyme, and 20% phytase, respectively. Muffins made with cellulase- and phytase-treated whole wheat flour showed improved quality and bioavailability of minerals. Phytase- and cellulase-treated whole wheat flour may be useful for development of functional food products with improved bioavailability of minerals.

The quality characteristics of muffins with different types of rice flour, such as soft flour (CON), soft rice flour (SRF), floury rice flour (FRF), and rice flour (RF) were assessed by using Image J program, which includes their particle size analysis, moisture content, pH, color, specific volume, baking loss rate, texture. (D[4, 3]) is weighted mean diameter, which is directly obtained in particle size measurements showed large values in the order of rice flour, floury rice flour, soft rice flour, and soft flour. The moisture content was high in the CON and SRF groups with small particle sizes. There was no significant difference in pH, L and b value. The a value was significantly low only in the RF group with large particle size. The smaller the particle size, the higher the specific volume and baking loss rate. Image J showed that the number of pores decreased when fewer smaller particles were the powder, but the pores were larger. Among the rice flours, the SRF group, excluding the CON group, scored high in all the acceptability elements. The results from this study can be used as basic data that can contribute to research on various rice-processed foods.

The antioxidant, physicochemical, and sensory properties of muffins using fermented Curcuma longa L. were investigated. Sensory properties of the samples were examined, and the correlation between the physicochemical, antioxidant, and sensory properties was studied. The pH of the samples was pH 7.26-7.42, which was the optimal pH range for the air formation of the dough, color, or volume. The antioxidant activities of the sample group were significantly higher than the control (p<0.05). In the sensory intensities, the 1.0 and 1.5%-added sample groups showed a similar savory aroma, sweet aroma, savory taste, sweet taste, and texture to those of the control. Samples containing 1.0 and 1.5% showed similar overall acceptance values to the control. The muffin containing 1.0 or 1.5% fermented Curcuma longa L. powder was developed successfully, and it was concluded that the developed muffin with the fermented turmeric powder could be a highly valued product in the increasingly competitive muffin food industry.
