  • This study intends to present basic materials for the development and production of functional dumpling skins by making rice flour-added functional dumpling skins and analyzing the nature of its quality. The moisture content of dumpling skins increased with high addition of rice flour. The color value of dumpling skins changed little with high addition of rice flour. The hardness of dumpling skins showed significant difference in all storage periods with the addition of rice flour. For the sensory properties of dumpling skins with the addition of rice flour, where 25% and 50% rice-flour were added, dumpling skins showed a high score in overall quality for O-day and 7-days of storage. In particular, the 50% rice-flour dumpling skin mixture indicated the highest score. For the correlation between textural and sensory properties according to the addition of rice flour, 0 day-stored dumpling skins showed a positive correlation between smoothness and moistness in the mouth feel and the overall quality (p<0.01) in the sensory properties. Wheat odor (r=0.68) and chewiness (r=0.65) also correlated positively with overall quality (p<0.05). Hardness in textural properties correlated positively with moistness (r=0.69) and the mouth feel (r=0.65) of dumpling skins (p<0.05). Hardness in textural properties correlated positively with adhesiveness (r=0.99) and chewiness (r=0.93, p<0.01). Dumpling skins stored for 7 days showed a positive correlation between hardness, chewiness, and moistness in the mouth feel and overall quality (p<0.05) in the sensory properties. Hardness in textural properties correlated positively with gumminess (r=0.65, p<0.05).

  • Appropriate types and concentrations of starch-based fat replacers which are low-pH stable, shear resistant and heat stable were selected to develop reduced-fat mayonnaise without affecting taste, texture and emulsion stability. Four kinds of commercial fat replacers [Neutral DR (DR), Stellar 100X (SX), Sta Slim 150 (SS) and N-Lite L (NL)] were thermally activated after appropriately hydrated and applied to mayonnaise formulation. For each fat replacer, eight recipes having various ratios of soybean oil/fat replacer(95/5 to 60/40) were formulated and compared with standard formulation(100% soybean oil) using rheological and sensory evaluations. All tested starch pastes showed pseudoplastic behavior, time-dependent thixotropic gel characteristics. The increasing order of pseudoplasticity and yield stress was RM, NL, SS and ST. The hardness and adhesiveness of each fat replacer-added mayonnaise was increased in the same order as above. Formulated mayonnaise which contained higher ratio of fat replacer showed lower values in hardness and adhesiveness. ST at up to 25% oil replacement exhibited the highest oil replacing ability among four replacers. ST-added mayonnaise also exhibited the highest sensory score and emulsion stability among all products including standard formula. The high sensory score in spreadability of RM-added mayonnaise well reflected the consistent index of RM paste. Use of fat replacers reduced oily odor and greasy aftertaste of mayonnaise.

Dietary fiber, volume, SEM, TBA, color, texture characteristics and sensory evaluation of yackwa were investigated. The dietary fiber content of rice wine cake was 10.24%, and the dietary fiber content of yackwa increased with added rice wine cake. The extensibility value increased with more rice wine cake. SEM revealed, many holes in a delicate structure with many layers. During a 4-week storage period, yackwa containing rice wine cake had lower TBA values than control, except for the sample containing 4% rice wine cake. The TBA value of yackwa containing 4% rice wine cake had the highest TBA value. The L value and b value of samples decreased with the addition of rice wine cake and storage time, but the value increased with added rice wine cake according to the storage time. The hardness, cohesiveness and gumminess of yackwa increased according to the time of storage and the addition of rice wine cake, but the springiness and chewiness of yackwa decreased. In sensory evaluations, all items received the lower scores according to the storage time. Yackwa that contained 1%(RWC1) received the highest score for color and flavor, and yackwa that contained 2% (RWC2) had the highest score for crispness and roast. Overall preference was, in order: RWC2 > RWC1 > CON > RWC4. Yackwa that contained $1{\sim}2%$ rice wine cake possessed superior features in most of the quality properties and in sensory evaluation, so yackwa that contains rice wine cake can be used as a functional food.

  • Objective: This study was conducted to evaluate quality characteristics of cured pork loin with natural nitrite source from Swiss chard. Methods: Pork loin was cured in brine and the ratio of water and fermented Swiss chard (FSC) solution in the brine was changed by 4:0 (control), 3:1 (T1), 1:1 (T2), 1:3 (T3), 0:4 (T4), and pickled samples with 0.012% sodium nitrite (PC, positive control) and nitrite free brine (NC, negative control) were considered as the control. Results: The pH values of cured pork loins with FSC were decreased with increasing addition level of FSC. Cooking loss was not significantly different among all treatments. T4 had the lowest value in moisture content and lightness value and the highest value in curing efficiency. The redness value of T4 was not significantly different from that of PC in raw. After cooking, however, it was higher than that of PC. The yellowness value of cured pork loin added with FSC was increased with increasing level of FSC. Volatile basic nitrogen content of cured pork loin added with FSC was higher than PC and NC. Thiobarbituric acid reactive substance value of cured pork loin added with FSC was decreased with increasing FSC level. Residual nitrite level and shear force were increased with increasing FSC level. In the sensory evaluation, sensory score for flavor, off-flavor, chewiness, juiciness, and overall acceptability were not significantly different among all treatments. However, sensory score for color was increased when the concentration of FSC added to pork loin was increased. Conclusion: The FSC solution had a positive effect on redness and lipid oxidation. As shown by the results in protein deterioration and sensory, Swiss chard can replace sodium nitrite as natural curing agent.

  • The physiological and sensory properties of breads made from waxy black rice flour (WBRF) and wheat flour were investigated. The waxy black rice bread was manufactured with 10, 20, 30, or 40% waxy black rice flour(w/w). The bread volume decreased from 2,096.7 mL to 1,703.4 mL as the WBRF content increased from 0% to 40%. The lightness(L-values) decreased with increasing WBRF concentrations, and the redness value(a-values) increased. The yellowness(b-values) slightly decreased with increasing WBRF content. The textural characteristics of the bread c겨mb were influenced by additions of WBRF. The breads containing WBRF had decreases in hardness for the 10% and 20% WBRF groups, whereas increases in hardness were shown with the 40% addition of WBRF. The springiness decreased with increasing WBRF content. The gumminess and chewiness of the waxy black rice bread decreased at the 10% and 20% additions. In the sensory evaluation, sensory scores decreased with increasing WBRF content for the appearance, external color, crumb color and grain of the waxy black rice bread. Overall acceptability for the 10% and 20% WBRF additions did not differ significantly from the score of the control group.
