  • This study was conducted to evaluate the quality characteristics of sponge cake consisting of 10%, 20%, 30%, 40% and 50% Helianthus tuberosus powder (HTP). With higher HTP contents in sponge cake, pH of sponge cake batter decreased significantly, whereas specific gravity was increased significantly (p<0.05). Meanwhile volume and symmetry indices of sponge cake were inversely proportional to HTP amounts. With higher HTP content in sponge cake, L value (brightness) of crumb significantly decreased (p<0.05), whereas a value (redness) significantly increased (p<0.05). b value (yellowness) of crumb in 40% and 50% HTP sponge cakes were significantly different from b value of crumb in 10%, 20% and 30% HTP sponge cakes. In 10~40% HTP sponge cake, L value, a value and b value all decreased significantly with higher HTP content in sponge cake. However in 40% and 50% HTP sponge cakes, there was no significant difference in any value. For texture characteristics, hardness of sponge cake significantly increased while cohesiveness decreased (p<0.05) with higher HTP content in sponge cake. On the other hand, springiness and gumminess of sponge cake did not change. Sponge cake containing 10% HTP showed the highest values for every organoleptic property. The results of this study suggest that sponge cake containing 10% HTP is the most appropriate for quality characteristics. This study also provides a way to increase the quality, texture characteristics, and organoleptic properties of sponge cake while reducing HTP content to less than 10% in order to qualify consumer taste.

  • The effects of partial replacement of flour with isolated soy protein (ISP) on sponge cake quality were investigated. The replacement did not cause any significant changes in physical characteristics of sponge cakes including specific gravity, specific volume and expansion ratio. As the level of ISP replacement increased, the sponge cakes were darker in color, harder, chewier and drier than control groups. The textural characteristics (hardness, cohesiveness, springiness, gumminess and chewiness) of the sponge cakes also increased as the level of flour replacement increased. Up to 15% of the flour could be replaced by ISP without diminishing the sponge cake quality.

  • This study was conducted to assess the effects of mugwort powder (3% and 5%) on sponge cake made with medium and cake flour. After preparing sponge cakes with mugwort powder, the water activity (Aw), softness and color of crumbs were tested and the sensory properties were evaluated. The water activity of the sponge cakes containing different quantities of mugwort powder did not differ greatly. The springiness and hardness of the sponge cakes with mugwort powder were all lower than that of the control. With regard to the color of the sponge cakes, the L values were reduced, but the a and b values were increased in response to the addition of mugwort powder, resulting in the sponge cake containing mugwort having a darker color. The micrographs of the sponge cakes with mugwort powder showed a slightly lower porosity than the control. In addition, the results of the sensory test showed that cakes containing mugwort powder had low scores. However, it is still possible to make the sponge cakes using mugwort powder and the sponge cakes prepared with flower containing 3% of mugwort powder had better evaluation than those prepared using other amounts of mugwort powder.

  • Asparagus, which was known to be a good source of dietary fiber and vitamins, has been reported to possess various medical actions such as antioxidant and blood pressure regulating effects. In order to examine the quality and antioxidant characteristics of asparagus, asparagus sponge cakes were prepared with different ratios of freeze dried asparagus powder (0%, 2%, 4%, 6%, 8%, w/w) in this study. With the increase of asparagus powder content in the sponge cakes, the specific gravity and baking loss increased while the dough yield decreased significantly. The moisture contents of the sponge cakes were not significantly different between the control and the cakes prepared with asparagus powder. The pH of the sponge cakes decreased significantly with increased amounts of asparagus powder. Furthermore, the pH of the sponge cake containing 8% asparagus powder was the lowest at 7.49. With the increase of asparagus powder content in the sponge cakes, lightness (L) and redness (a) decreased, whereas yellowness (b) increased. In texture analysis, the hardness and chewiness of the sponge cakes increased as the asparagus powder content increased, while the cohesiveness of the sponge cakes with asparagus powder decreased. Both total polyphenol content and DPPH (1,1-diphenyl-2-picryl hydrazyl) radical scavenging activity increased significantly with increased levels of asparagus powder content in the sponge cakes. In a sensory evaluation using a scale of 1-7, the sponge cake containing 8% asparagus powder had the lowest sensory preference scores. Therefore, the results of this study suggest that sponge cake prepared with 6% asparagus powder is the most appropriate product for quality characteristics.

  • A three-dimensional, porous collagen/chitosan complex sponge was prepared to closely simulate basic extracellular matrix (ECM) constitutes, collagen and glycosaminoglycan. The complex sponge was prepared by a lyophilization method and had the regular network with highly porous structure, suitable for cell adhesion and growth. The pores were well interconnected, and their distribution was fairly homogeneous. The complex sponge was crosslinked using 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide (EDC) and N-hydroxysuccinimide (NHS) to increase its boilogical stability and enhance its mechanical properties. The crosslinking medium has a great effect on the inner structure of the sponge. The homogeneous, porous structure of the sponge was remarkably collapsed in an aqueous crosslinking medium. However, the morphology of the sponge remained almost intact in a water/ethanol mixture crosslinking milieu. Mechanical properties of the collagen/chitosan sponge were significantly enhanced by EDC-mediated crosslinking. The potential of the sponge as a scaffold for tissue engineering was investigated using a Chinese hamster ovary cell (CHO-K1) line.

  • The principal object of this study was to assess the effects of garlic powder(2 % and 4 %) on the sponge cake made with medium and cake flour. After making sponge cakes with garlic powder, water activity, softness, color of crumb, and sensory test were tested. Water activity(Aw) of the sponge cakes with different quantity of garlic powder were increased during 7 days storage. These meant that garlic powder had absorption effect. The Max G and springiness of the sponge cakes with garlic powder were all lower than that of the control. With regard to the color of the sponge cakes, the L values were reduced, but the a and b values were increased with the increment of percent of garlic powder. The micrographs of the sponge cakes with garlic powder evidenced slightly lower porosity than the control. And, the results of sensory test showed that the increment of the addition of garlic powder had low scores. But we know the possibility to make the sponge cakes using garlic powder. And the sponge cakes with medium flour using 2% of garlic powder had better evaluation than others using garlic powder.

  • The sponge city construction is being carried out in China, and how to reasonably determine the scale of the sponge city facilities is a key point that the planners and designers should seriously solve. In this paper, taking determination of the sponge city facilities in a residential building in Shenzhen as an example, the layout and scales of the rainwater tanks, raingardens, ecological roofs and permeable pavements are decided by using the volumetric method and stormwater management model (SWMM). The calculated results by the two methods are compared and analyzed. The results show that the scales of the sponge city facilities determined by the two methods are almost the same, and it means that any method can be used to determine the scale of sponge city facilities. The volumetric method is relatively simple, and it is suggested to use to determine the scale of sponge city facilities during planning stage. While SWMM is more complex and requires a lot of input conditions, but it can provide the reduction effects of the sponge city facilities for rainfalls with different recurrence periods. Therefore, SWMM is recommended to use the calculation of the hydrological process of the sponge city facilities during the design stage.
