  • Quality characteristics of functional bread added with different concentrations of potato juice and processed by basic formulation were investigated. Specific volume and baking loss of bread added with 20% potato juice (potato juice : water = 20 : 80) were the highest. Moisture and crude protein contents increased with increasing content of potato juice, while crude lipid content decreased. Lightness (L value) and yellowness (b value) of bread decreased with increasing content of potato juice, while redness (a value) increased. Texture measurement showed springiness, cohesiveness, and brittleness increased with increase of potato juice content. Highest sensory scores for color (p < 0.001), flavor, and taste (p < 0.05) were obtained from bread added with 20% potato juice, while appearance (p < 0.01) and texture (p < 0.01) of control bread were highest. Glycoalkaloid contentsof bread added with 50 and 100% potato juice were 2.85 and 5.79 mg%, respectively.

  • The purpose of this study was to examine the quality variations of cake and cake batter when either butter or soybean oil was added in plain sponge cake batter. Soybean oil or butter was added to the batter at ratios of 20, 40, and 60% at 20, 35, 60, and $80^{\circ}C$. The physico-chemical properties of cake batter and cake were measured to evaluate the effects of ratio and temperature of butter and soybean oil. At higher ratios of butter or soybean oil and lower temperatures, the specific gravity of the cake batter increased while the interrelations among weight, volume, and specific loaf volume decreased. L- and b- values were the same, but a-value increased remarkably with higher ratios of butter. The effect of adding butter or soybean oil on hardness was shown to be lowest at 40% and $80^{\circ}C$. Baking loss in the baking process with soybean oil decreased with increasing oil quantity and temperature. Moisture content did not change with temperature, but did decline with increasing amounts of butter or soybean oil. These results show that the optimum condition for sponge cake would be 40% soybean oil at $80^{\circ}C$.

  • The effect of baking on the physicochemical and sensory properties was investigated using a model system of sponge cakes incorporated with pine leaf powder (PLP) as a value-added food ingredient. PLP was incorporated into cake batter at 5 levels (0, 2, 4, 6, and 8%, w/w) by adding an equivalent amount based on the weight of wheat flour. After appropriate mixing, sponge cakes were baked at $170^{\circ}C$ for 30 min in an oven. The baked cakes were cooled to room temperature for 1 h prior to all measurements. The pH, moisture content, specific volume, height, volume index, and symmetry index decreased significantly with the increase in PLP content (p<0.05). On the contrary, specific gravity of the batter and baking loss increased (p<0.05). The lightness of the cakes decreased, whereas redness increased significantly with the higher amount of PLP in the formulation (p<0.05). Hardness also increased significantly (p<0.05). Both total polyphenol content and DPPH (1,1-diphenyl-2-picryl hydrazyl) radical scavenging activity increased significantly by the addition of PLP (p<0.05). The consumer acceptance test indicated that the addition of PLP up to 4% did not cause a significant unfavorable effect on the consumer acceptances in all attributes. The sponge cakes with 2-4% PLP would be recommended with respect to the overall acceptance score while taking advantage of the functional properties of PLP without sacrificing the consumer acceptability.

  • Effects of azodicarbonamide (ADA) were investigated on the rheological properties of flour dough by measuring farinogram, amylogram and extensogram based on the amount of ADA added. Quality characteristics of the bread made with the ADA added dough were also evaluated by measuring dough volume, moisture content, pH, proofed time, baking loss and textural characteristics. The farinogram showed that water absorption, stability and elasticity of the dough with ADA were higher than those without ADA. However, its absorption time and weakness decreased compared to the dough without ADA. Through the amylogram, it was found that gelatinization temperature and maximum viscosity increased, but temperature of maximum viscosity reduced in the dough with ADA. The extensogram showed that the area and resistance of the dough increased slightly but extensibility decreased drastically after fermentation, resulting in the ratio of resistance and extensibility (R/E) of the dough with ADA was lower than those without ADA. The bread prepared with the dough containing ADA after freezing up to 12 weeks showed higher pH and specific loaf volume but lower moisture content, second proof time and resistance than those without ADA.

  • 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.
