  • In this study, rice flour sponge cakes were prepared by replacing 50% of the sucrose with oligosaccharides. Isomaltooligosaccharide and fructooligosaccharide were used as the oligosaccharides. The effects of oligosaccharides on the physical, textural and sensory properties of the cakes were then examined. The oligosaccharides increased batter viscosity and decreased batter specific gravity and baking loss. The moisture content, specific loaf volume and loaf volume index of the cake increased by replacing 50% of the sucrose with oligosaccharides. Internal and exterior color determinations showed that the 'L' value of the sponge cake with oligosaccharides was lower than that of the control, indicating a darker crust and crumb with the oligosaccharide substitution. Decreases in textual hardness, chewiness, and brittleness occurred with the oligosaccharides. Sensory panels perceived that the oilgosaccharide darkened the crust of the rice flour sponge cake and the panelists rated the cakes with the oilgosaccharide substitutions as sweeter, softer and more moist. The rice flour sponge cakes with isomaltooligosaccharides had a significantly higher acceptability then the others.

  • 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.

  • This study was carried out to investigate the effect of maltodextrin on the characteristics of low-calorie layer cake. Different levels of maltodextrin were added to the cake formula based on the weight of shortening. The specific gravity of cake batter was decreased by increasing the level of maltodextrin, whereas the viscosity showed an opposite trend. The microstructures of cake crumb observed by the scanning electron microscope showed the decrease of the number and size of air cells, and those of fat particles were also decreased by increasing the level of maltodextrin. The texture profile analysis of layer cake showed statistically significant differences according to the levels of maltodextrin. Hardness, gumminess and chewiness of the cake batter were decreased by adding maltodextrin, while springiness, cohesiveness and resilience increased. According to the sensory evaluation, the scores of taste and texture were decreased by adding maltodextrin, but the scores of appearance, color, flavor and overall preference of the layer cake increased. Overall results suggested that the addition of 35% maltodextrin could be the best replacing ratio for the low-calorie layer cake.

  • Physicochemical and textural properties, and sensory evaluation of low-fat sausages (LFSs) manufactured with 0.3 and 0.6% chitosan were investigated and compared with those of regular-fat sausages (RFSs). Although the batter pH was not changed with the addition of chitosan (p>0.05), product pH was reduced (p>0.05) with the addition of chitosan up to 0.6%. Proximate composition and cooking loss (%) were not affected by the addition of chitosan. Expressible moisture 1r91ues (EM, %) of LESs were lower (p<0.05) than those of RFSs, but not affected by the addition of chitosan. The addition of chitosan in the sausage formulation became harder, springier and more cohesive (p<0.05), whereas, no differences were observed (p>0.05) in these values of sausages containing between 0.3 and 0.6%. Batter viscosity was not affected by the addition of chitosan, but LESs with or without chitosan had lower viscosity than RFSs due to high moisture (%). Sensory evaluation results showed that LFSs containing 0.3% chitosan had most parameters similar to those of low-fat control. These results indicated that chitosan at the level of 0.3% can be used for the manufacture of LFSs without quality defect.

  • The quality characteristics (specific gravity, viscosity, color, texture and sensory evaluation etc.) of yellow layer cake added with black garlic powder were examined in order to use as a new functional food ingredient of black garlic powder. Specific gravity of cake batters was not affected by addition of black garlic powder. Viscosity (31,315~41,048 cP) of cake batters was increased as the addition level of black garlic powder increased. pH (7.54~6.18) and height (6.14~5.62cm) of cakes were decreased as the addition level of black garlic powder increased. Specific volume of cakes did not show any significant difference except the cake with 15% black garlic powder. In color of cake crust, crumb and batter, lightness (L) and yellowness (b) were decreased as the addition level of black garlic powder increased, while redness (a) was increased. Hardness and adhesiveness of cakes decreased as the addition level of black garlic powder increased Overall acceptability was the highest in yellow layer cake with 5% black garlic powder.

  • The aims of this study were to investigate the quality characteristics of yellow layer cake added with Sparassis crispa powder that were abundant in dietary fiber, and also to determine the most suitable amount of added S. crispa powder. Dried powder of S. crispa containing 61.8 g/100 g insoluble dietary fiber was added to the cake batter in Baker's percentage of 1%, 2%, 4%, and 8%. Cake batter containing 1% and 2% S. crispa powder showed similar pH, specific gravity, and viscosity values to the batter without S. crispa powder (control). As the amount of added S. crispa power increased, the volume, specific volume, baking loss, and brightness (for both crust and crumb) of the cake containing the powder tended to decrease. A greater amount of added S. crispa powder resulted in a decrease in hardness, gumminess, and chewiness of the cake containing the powder and also reduced the changes in hardness of the cake during 8 days of storage. The sensory analysis showed that cake containing 2% S. crispa had several desirable kinds of sensory attributes, such as color, flavor, taste, and texture compared to the control; whereas an addition of more than 2% S. crispa deteriorated the sensory quality of the cake. These results suggest that the most suitable amount of added S. crispa powder for preparing yellow layer cake was 2% in Baker's percentage.

  • This study was conducted to investigate the use of sugar alcohols as alternative sweeteners for replacing sucrose in sponge cake. The sponge cakes were prepared with only sucrose or a 50% replacement of sucrose with various sugar alcohols (erythritol, sorbitol, and xylitol). The specific gravity of cake batter containing only sucrose was significantly higher and the viscosity was significantly lower than those containing sugar alcohol (p<0.001). Among sugar alcohols, xylitol was the most similar to sucrose. The thermal characteristics, as assessed by differential scanning calorimetry, showed that sucrose delayed gelatinization of cake batter more than sugar alcohol, as the onset temperature and the peak temperature of cake batter containing only sucrose were higher than those containing sugar alcohol. The moisture content of cake containing sorbitol was the highest and that containing only sucrose was the lowest among cakes. The specific volume of cakes containing only sucrose and xylitol were higher and the baking loss rate of those were lower than other sugar alcohols. The volume and symmetry index of cake containing only sucrose were the highest among cakes (p<0.001), and xylitol was similar to sucrose for the above indices. The redness (a) and yellowness (b) values of crust containing only sucrose were significantly higher than those containing sugar alcohols (p<0.001). The a and b values of crumb containing erythritol were the lowest among cakes, showing a pale yellowish color. The microstructure, as assessed by scanning electron microscopy, showed that the cake containing only sucrose had more uniformly and finely distributed pores and a smoother cross section than that containing sugar alcohols. Cake containing xylitol was similar to cake containing only sucrose. Hardness, chewiness, and gumminess of cake containing only sucrose were higher than those containing sugar alcohols, whereas the adhesiveness of cakes containing sugar alcohols were higher than those containing only sucrose (p<0.01). Among sugar alcohols, xylitol was the most similar to sucrose in textural properties. In a sensory quality test, the tenderness and moistness of cakes containing sorbitol and erythritol were higher than those containing only sucrose and xylitol. The overall acceptance of cakes containing xylitol and only sucrose were higher than those containing sorbitol and erythritol (p<0.001). Thus, xylitol is more appropriate as a 50% replacement for sucrose than erythritol and sorbitol when preparing sponge cake.

  • The effects of adding goldenrod leaf (GL) and stem powder (GS) (1 and 2%) to sausage meat were evaluated for quality characteristics. The compositional properties, pH, cooking yield, instrumental color, emulsion stability, viscosity, texture, and sensory properties were investigated. Adding GL and GS increased the moisture and ash concentration in sausages. Furthermore, increasing the amount of added GL and GS helped to develop (p<0.05) cooking yield, emulsion stability, and viscosity in the meat batters. Sausages with 2% GL and GS had significantly higher springiness and hardness than those of the control. No significant differences in cohesiveness were observed among the treatments. CIE L*and CIE a*values were highest (p<0.05) in the control sausage. Treatment with 2% GL resulted in the highest CIE b* values (p<0.05) in batter and sausages. No significant difference was observed between the control and other treatments for the overall acceptability. Overall, this study indicated that GL and GS could be used as dietary fiber in sausages to improve quality characteristics.

  • Sodium chloride is used to improve various properties of processed meat products, e.g., taste, preservation, water binding capacity, texture, meat batter viscosity, safety, and flavor; however, many studies have shown that sodium chloride increases the resistance of many foodborne pathogens to heat and acid. Listeria monocytogenes has been isolated from various readyto- eat (RTE) meat and dairy products formulated with sodium chloride; therefore, the objective of this paper was to review the effects of sodium chloride on the physiological characteristics of L. monocytogenes. The exposure of L. monocytogenes to sodium chloride may increase biofilm formation on foods or food contact surfaces, virulence gene transcription, invasion of Caco-2 cells, and bacteriocin production, depending on L. monocytogenes strain and serotype as well as sodium chloride concentration. When L. monocytogenes cells were exposed to sodium chloride, their resistance to UV-C irradiation and freezing temperatures increased, but sodium chloride had no effect on their resistance to gamma irradiation. The morphological properties of L. monocytogenes, especially cell elongation and filament formation, also change in response to sodium chloride. These findings indicate that sodium chloride affects various physiological responses of L. monocytogenes and thus, the effect of sodium chloride on L. monocytogenes in RTE meat and dairy products needs to be considered with respect to food safety. Moreover, further studies of microbial risk assessment should be conducted to suggest an appropriate sodium chloride concentration in animal origin foods.

  • Fat and sugar reduced yellow layer cake system was developed with varied replacement level of 30%, 60%, and 90% for AD(amylodextrin) and 10%, 30%, and 50% for PD(polydextrose). Physicochemical and sensory characteristics were investigated and optimum replacement level was also decided using response surface methodology. Sample groups of PD10AD30 had significantly the lowest specific gravity and viscosity, indicating the stable batter system with high air incorporation. Sample groups with PD10AD90 showed the highest volume index and were not significantly different from those of the PD10AD30. Sensory results indicated that PD30AD30 were significantly the most springy and moist, and the least hard of all sample groups. Sample groups with PD10AD90 had the least adhesiveness value. To establish the optimum substitution level using RSM, the restriction level was set up as moistness over five point, hardness under five points, and adhesiveness under four points. The optimum substitution level was 20% for PD and 88% for AD.
