  • This study was conducted to determine the effect of different proportions of Alaska pollack surimi, chicken breast surimi and starch on textural properties of sausage. Sausage were manufactured such as Alaska pollack surimi(control), T1(90.91:0:9.09), T2(80:0:20), T3(62.5:37.5:0), T4(58.82:35.3:5.88), T5 (40:60:0) and T6(36.36:54.55:9.09) depending on different proportions of Alaska pollack surimi, chicken breast surimi and starch. Brittleness, breaking force and gel strength were significantly higher in T1 than the control(P<0.05), and breaking force, gel strength and folding test were significantly higher but sensory evaluation was significantly lower in T2 than the control(P<0.05). Breaking force, gel strength and jelly strength were significantly higher in T3 and T4 than the control(P<0.05). Gel characteristics and sensory scores were significantly higher but texture properties were significantly lower in T5 and T6 than the control(P<0.05). The T3 and T4 had similar textural and sensory properties in the surimi- sausage compared to the control. Therefore, the results of this study indicated that textural properties of sausage can be acceptable when chicken breast surimi replaced Alaska pollack up to 35%.

  • To determine the proper processing and storage conditions, physico-chemical, microbial and sensory properties of venison jerky under different dry times were measured during storage at $30^{\circ}C$ for 28 days. Samples were dried for 3 hr (T1), 4 hr (T2) and 5 hr (T3) at $75^{\circ}C$ in the smoke chamber, respectively. The pH of T1 was slightly lower than those of T2 and T3 as storage time increased. As dry and storage time increased, TBARS of T2 and T3 were significantly higher (p<0.05) than that of T1. In meat color, $L^*$ values of T3 showed slightly higher than those of T1 and T2, while at values were not clearly tendency by the passage of storage time. $b^*$ values of T2 and T3 were higher than that of T1. The water activity were significantly lower (p<0.05) in ,the order of T3$log_{10}$ CFU/g until 28 days and its number were accepted by sensory evaluation. In conclusions, T2 and T3 showed slightly high overall acceptability and lipid oxidative stability compared to T1 conditions. These results indicated that longer dry time ($4{\sim}5 hr$) of venison jerky would be better characteristics as compared to shorter dry time (3 hr) with increased storage time at $30^{\circ}C$.

  • The effect of different steamed garlic powder concentrations on sponge cake quality were investigated by analyzing both physicochemical and sensory properties. The sponge cakes were mixed with either steamed and freeze-dried garlic powders at different ratio [0, 2, 4, 6, 8 and 10 % (w/flow w)]. The density of the prepared dough increased with increasing amounts of steamed garlic powder when the concentrations were over 4%. The heights of the sponge cakes ranged from $3.53{\pm}0.12{\sim}3.60{\pm}0.15cm$ in the $4{\sim}8%$ steamed garlic powder samples, and were significantly higher than the control. The specific loaf volume of the cake was $3.86{\pm}0.07mL/g$ the highest in the 4% steamed garlic powder samples. When the garlic powder concentration was over the 6%, the specific loaf volumes of the sponge cakes decreased with increases in garlic powder contents. The measured L- and b-values of the crust were significantly decreased with increasing garlic powder concentration while the a-value gradually increased. The L-value of the crumb increased with increasing steamed garlic powder concentration, especially at concentrations greater than 4%. The a-values were higher in the steamed garlic powder treatments than in the control. however, no significant differences were found in the concentrations over 4%. The hardness of the control was $812.42{\pm}56.69g/cm^2$, whereas it ranged from $1005.36{\pm}43.65{\sim}1522.78{\pm}204.95g/cm^2$ in the experimental groups. Hardness increased with increasing garlic powder concentration. When considering moistness, overall acceptability, and other characteristics, the optimal concentration of steamed garlic powder was found to be 4%.

  • This study was investigated for the purpose of obtaining basic data which can be applied to processing of canned sea mussel using tomato paste. Shell were washed, and then steamed and shucked. Sea mussel meat was prepared with ratio of sea mussel 90g, tomato paste sauce 65g(tomato paste 42%, gum guar 1.0%, salt 2.0%, starch syrup 2.0%, cooking wine 1%, water 52%). The sea mussel meats were packed with vacuum seamer in 301-3 can, and then sterilized for various F0 value(F0 8-12 min.) in a steam system retort at $118^{\circ}C$. The factors such as pH, VBN, amino-N, total amino acid, free amino acid, chemical composition, color value (L, a, b), texture profile, TBA value, mineral, sensory evaluation and viable bacterial count of the canned sea mussel produced with various sterilization condition(F0 8-12 min.) were measured. The same element was also measured during preservation. The results showed that the product sterilized at F0 8 min. and preserved for 90 days were the most desirable.

  • This study was conducted to evaluate the quality characteristics of pickled radish wrap supplemented with calcium chloride ($CaCl_2$) at different concentrations. With $CaCl_2$ supplementation, initial pH and acidity were 3.8~4.0 and 2.7~3.0% (w/v), respectively. During the 28 day-preservation at $4^{\circ}C$ or $50^{\circ}C$, the initial pH and acidity were maintained. However, when the pickled radish wrap was preserved at $25^{\circ}C$, it had lower pH (by 0.5) and higher acidity (by 1.9~2.2%) when compared with the initial values. The difference in color (${\Delta}E$-value) of the pickled radish wrap preserved at $50^{\circ}C$ was significant (${\Delta}E$-value 23~27), though the hardness of the sample prepared at $4^{\circ}C$ or $25^{\circ}C$ showed no distinguishable differences at various concentrations of $CaCl_2$ supplementation (0.1, 0.2, 03, 0.4, and 0.5%). However, once preserved at $50^{\circ}C$, it resulted in the greater hardness with the higher concentrations of $CaCl_2$ supplementation. In terms of softness, the overall trend in changes was similar to the hardness. A sensory evaluation using the samples preserved at $4^{\circ}C$ for 28 days demonstrated that the preparation with 0.4% $CaCl_2$ ranked highest in taste, hardness and overall acceptability. It wass suggested that supplementation with 0.4% $CaCl_2$ would be most appropriate to improve the textural properties of pickled radish wrap while maintaining its organoleptic quality.

  • Four different spices (herbs) including rosemary, oregano, basil & sage and green tea were added individually to the ground pork or ground chicken with different percentages of 0.5, 1.0, and 1.5, respectively. The consumer sensory qualities of the five natural herbs and their antioxidant effects were evaluated using pork- and chicken-Yukwonjeon. In our consumer sensory evaluation, the 0.5% herb addition and control groups had generally better acceptability than the higher addition groups. In particular, pork-Yukwonjeon with the addition of 0.5% of green tea or oregano and chicken-Yukwonjeon with the addition of 0.5% of green tea or rosemary 0.5% were generally preferred more profoundly on the acceptance and ranking tests. However, sensory differences, especially in texture, among the different samples were reduced after storage. With regard to the results of lipid oxidation without storage, the TBARS values of the herb addition groups were slightly lower than those of the control group, but not significantly so (p>0.05). The antioxidant effects of each herb achieved higher values at longer storage times and with higher levels of added herbs. The antioxidant effects differed with different kinds of meat. The addition of the herb samples resulted in TBARS value reductions of $15.0{\sim}45.8%$ and $9.5{\sim}31.0%$, respectively, in the pork and chicken-Yukwonjeon stored at $6^{\circ}C$. Furthermore, the antioxidant effects of herbs during storage at $-20^{\circ}C$ were observed as reducing in the TBARS values of $8.4{\sim}31.7%$ and $19.0{\sim}33.0%$ in the pork-and chicken-Yukwonjeon, respectively. Green tea evidenced the highest levels of antioxidant activity on lipid oxidation, as it was acceptable even at higher concentrations according to our sensory evaluations. These results illustrate the possibility of producing superior Yukwongen with green tea and herbs, according to the different kinds of meat used.

  • We stored sweet pumpkins at $8^{\circ}C$, $12^{\circ}C$, $12^{\circ}C$ plasma curing and room temperature (control) for 180 days. During this time, the quality characteristics were analyzed within the different groups. No spoiling occurred in either of the storage conditions for up to 120 days, and the marketability was good. After 120 days, spoiling sharply increased by over 70% in the control group, while in the $12^{\circ}C$ group it decreased to 20~60%. Conversely, spoiling was completely absent in the $8^{\circ}C$ and $12^{\circ}C$ plasma curing groups during the overall 180 days of storage. The lowest moisture content was found in the $8^{\circ}C$ group and the quality of the pumpkins was excellent during the entire storage period. The color of pulp was better in the $12^{\circ}C$ and $12^{\circ}C$ plasma curing groups, with best results were found in the latest. Both the $8^{\circ}C$ and $12^{\circ}C$ plasma curing groups maintained their dark green surface colors, while both the $12^{\circ}C$ and control groups turned from green to yellow. All groups showed a reduction in their initial hardness, with the $8^{\circ}C$ group staying the hardest. Soluble solid and mealiness was increased to the storage during 90 days while decreased, that were long to maintain the mealiness texture in the $8^{\circ}C$ storage pumpkin. The overall acceptability from sensory evaluation was higher in the $12^{\circ}C$ plasma curing group, when compared to those of the $8^{\circ}C$, $12^{\circ}C$ and control groups storage conditions.

  • In order to investigate the utilization of the Omija (Schizandra chinensis Baillon) extract as a natural coagulant for manufacturing soybean curd, the quality characteristics of white (Baktae) and black (Seoritae) soybean curds, coagulated by the Omija extract or $MgCl_2$, were evaluated. Crude protein ($6.14{\pm}0.30$ and $6.25{\pm}0.18%$, respectively) and crude lipid ($10.86{\pm}1.74$ and $11.29{\pm}1.69%$, respectively) contents of white and black soybean curds coagulated using the Omija extract were higher than those coagulated using $MgCl_2$. Black soybean curds coagulated using the Omija extract showed higher L, a, and b values than those using $MgCl_2$. The most abundant amino acid in white and black soybean curds coagulated using the Omija extract was arginine (3.74 and 3.71 mg/100 g, dry basis, respectively). The amounts of Ca, K, Mg, and Na were the highest in both soybean curds prepared with the Omija extract. The sensory evaluation (color, flavor, taste, texture, and overall preference) showed that white and black soybean curds coagulated using the Omija extract were more preferred than those produced using $MgCl_2$. The results suggested that using the Omija extract as a natural coagulant agent could improve the quality and sensory characteristics of soybean curds.

  • The effects of vegetable oils addition on the quality characteristic of pound cake were investigated. The volume of pound cake prepared by adding vegetable oils increased from 1005.8 to 1075.8 mL, compared to 752.8 mL for the control. The volume index of pound cake prepared by adding vegetable oils increased by 3.46${\sim}$3.65, compared to 2.88 for the control. The hardness and penetration of pound cake with added vegetable oils were decreased significantly compared to those of the control during storage for 72 hours. The texture of pound cake with added vegetable oils was not decreased compared to that of the control. The lightness and yellowness values of the cake increased and the redness values of the cake decreased by adding vegetable oils compared to those of the control. The sensory quality of the pound cake with added vegetable oils, as estimated by color, taste, moistness and overall acceptability, was better than that of the control.

  • This study was conducted to evaluate the quality characteristics of low-fat emulsion type sausages containing 0% tomato powder (C), 5.0% ground raw tomato paste (T1) and 0.5% freeze dried tomato powder (T2) during storage at $5{\pm}1^{\circ}C$ for 30 days. The crude protein content of T2 was significantly lower (p<0.05) than that of the other sausage types. Moisture, crude fat and crude ash contents of the sausages during storage were not affected by the addition of tomato. The pH and shear force ($kg/cm^2$) values of C were significantly higher (p<0.05) than those of T1 and T2. There was no significant difference among the different sausages in cooking loss, ranging from $13.00{\sim}14.98%$. The WHC values of T1 and T2 were significantly higher (p<0.05) than that of C. The values of TBARS were significantly (p<0.05) increased for ail sausages following storage. The TBARS value (mg MA/kg) of C was significantly higher (p<0.05) than those of T1 and T2 at 15 days of storage, however T1 was significantly higher (p<0.05) than the other sausages after 30 days of storage. The meat color values tended to decrease with increased storage time. Microorganism analysis revealed that all sausage types did not reach $4.4log_{10}CFU/g$ until 30 days of storage. The texture, brittleness, Hardness, and springiness of each sausage type were not significantly different after 1 day of storage, while the cohesiveness, gumminess and chewiness of T1 and T2 were significantly higher (p<0.05) than that of C. T1 and T2 sausages had a slightly higher score regarding color, aroma, tenderness and overall acceptability, however the sensory evaluation score among the different sausage types was not significantly different (p>0.05). In conclusion, low-fat sausage with added tomato showed higher lipid oxidative stability during storage than sausage to which no tomato was added.
