  • The stability of red pepper seed oils during storage at 20${\pm}$3$^{\circ}C$, 40${\pm}$3$^{\circ}C$ and heating at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$ were measured to evaluate red pepper seed oil as a cooking oil. Two species of red pepper seeds (native, improved) were dried by either sunlight or heating to prepare the oil samples of NS (native, sunlight-dried), IS (improved, sunlight-dried), NF (native, heated), and IF (improved, heated). During storage at 20${\pm}$3$^{\circ}C$ or 40${\pm}$ 3$^{\circ}C$, acid values (AV) of all red pepper seed oils were higher than that of soy bean oil (SBO), however, peroxide values (POV) were similar to SBO. Antioxidative stability of NS was better than SBO but IF was not. By the heat treatments at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$, NS was identified to have better antioxidative stability than SBO and IF was the lowest. In sensory evaluation of each deep-fat fried potato-chip at 180${\pm}$5$^{\circ}C$, potato-chips fried in NS were better than that of SBO for color, taste, and flavor. NS-fried potato-chips got the highest score in overall acceptance (p<0.05), however, those of IF showed little acceptance. When blended oils (SBO: NOS, 0, 25, 50, 75%) were used, 50% blended oil was the best for taste, color, flavor, cripness, and total acceptance.

  • Bamboo leaf powder was added to Jeolpyun to increase the neutraceutical effects and storage period. The bamboo leaf powder was added to rice flour at ratios of 0, 4, 6, 8, and 10% (w/w), and they were treated with aqueous malt extract to extend storage. The Jeolpyun was stored at $20^{\circ}C$ for 72 hr, and the physical and sensory characteristics were evaluated. As a result, the crude fat, crude protein, moisture, crude ash and total dietary fiber contents in bamboo leaf powder were 4.36, 11.29, 3.37, 7.33, and 65.57%, respectively. The Hunters L, a, and b values decreased significantly as the amount of bamboo leaf powder increased; however, the a and b values increased during storage. The paste property setback values decreased with the malt extract treatment and with increasing amounts of bamboo leaf powder. In a sensory analysis, hard texture strength in the malt extract and bamboo leaf powder treatment groups was less than that in the control during storage. The Jeolpyun prepared with malt extract and no bamboo leaf powder was the most accepted by consumers. Although adding bamboo leaf powder resulted in less consumer acceptance except for the flavor attribute, adding 4% and 8% bamboo leaf powder resulted in better consumer acceptance for texture, taste, and overall acceptance than that of the control. In a microbial analysis, adding bamboo leaf powder resulted in fewer mold colonies. In conclusion, adding 4% bamboo leaf powder and malt extract to Jeolpyun improved its storage properties.

  • This study was carried out to determine the quality characteristics of Jeju mandarin orange jelly with various gelling agent such as agar, ${\kappa}-carrageenan$ and gellan gum for the aged. The concentration of agar was 0.4-0.6% and that of ${\kappa}-carrageenan$ and gellan gum was 0.2-0.4%. The color value, gelling temperature, melting temperature, break down rate, textural properties and sensory acceptance test of Jeju mandarin orange jelly with various gelling agent were measured. Average age of the subjects for acceptance test was 78.23. Redness and yellowness of Jeju mandarin orange jelly with agar was lower than that with ${\kappa}-carrageenan$. The gelling and melting temperature of Jeju mandarin orange jelly with agar was lowest among the jellies. Break down rate of Jeju mandarin orange jelly with agar was highest among the jellies. Above results showed that the stability of Jeju mandarin orange jelly with agar was inferior than that with ${\kappa}-carrageenan$ and gellan gum. Hardness, adhesiveness and springiness of Jeju mandarin orange jelly with agar was lowest among the jellies and sensory acceptance of Jeju mandarin orange jelly with gellan gum was highest among them. Thus, gellan gum was appropriate gelling agent for the Jeju mandarin orange jelly with regard to the acceptability and the depression of sour taste in Jeju mandarin orange jelly could improve the acceptability for the aged.

  • Four dietary fiber enriched menus for the aged were developed and physicochemical were analyzed. Major foods enriching the dietary fiber were as following; kimchi & bean sprouts soup and sweet potato for menu 1, chamcheunamul and grape for menu 2, mushroom and kimchi for menu 3, dried radish leaves and green pepper for menu 4. One portion of calorie, carbohydrate, protein and fats for the aged were calculated as 567 kcal, 92.8 g, 21.3 g and 12.6 g, respectively based on recommended daily allowances for adults. Dietary fiber content increased in the menus 1, 2, 3 and 4 were 17.27%, 20.84%, 16.91%, and 23.64%, respectively. The menu 1 had significantly the highest acceptance scores among the rice, soups, side dishes and overall desirability with the acceptance sores of 4.77, 4.58, 4.62 and 4.69, respectively(p<0.05). Female showed significantly the higher acceptance scores of all of the enriched fiber menu than those of male. Moisture contents of the boiled rice with barely in menu 3 had significantly the highest value of all(p<0.05) and the side dishes of all menus did not show any significant differences at p<0.05. The pH value of boiled rice with barely in menu 3 was significantly the highest and menu 1 of kimchi & bean sprouts soup had significantly the lowest pH values(p<0.05). Hunter L value was significantly the highest in boiled rice with barley. The dietary fiber enriched menus were successfully developed for application and standardization in the meal service planning for the aged as one of trials of basic data collection.

  • The aim of this study was to determine the relationship between sensory properties and Warner-Bratzler shear (WBS) for branded Hanwoo beef. Eight subprimal cuts purchased from the branded Hanwoo beef of 3 quality grades ($1^{++}$, $1^+$, 1) at 13 stores were determined the tenderness using WBS and evaluated the sensory properties (tenderness, flavor, juiciness, overall acceptance) by trained sensory panels. The results of sensory evaluation were analyzed by four WBS value classes (<3.46 kg, 3.46-4.09 kg, 4.09-4.72 kg, >4.72 kg). The results from the sensory evaluation (tenderness, flavor, juiciness, overall acceptance) for subprimal cuts of WBS force value less than 3.46 kg had high scores, whereas WBS force value more than 4.72 kg had low scores (p<0.05). Correlation coefficient of WBS measurements with sensory ratings was -0.67 (tenderness), -0.53 (flavor), -0.49 (juiciness), and -0.57 (overall acceptance). From these results, consumers can distinguish sensory taste of branded Hanwoo beef using WBS categories and beef industry can apply index of taste for brand Hanwoo beef by WBS categories.

  • This study aimed to enhance the applications of dates as a food material that can be utilized and stored easily by improving the inefficient process of the traditional cooking procedure. To this end, this study investigated the physico-chemical and nutritional properties of jujube pulp powder, and compared the traditional and newly developed methods of making yakbap, yakpyon, and jujube porridge. According to the analysis of physical and chemical properties, the jujube pulp powder contained 5.4% moisture, 2.6% crude ash, 6.6% crude protein, 0.35% crude fat, and 4.7% crude fiber. The water activity was 0.95% in jujube pulp while it was 0.24% in jujube pulp powder. In addition, the jujube pulp powder had a total sugar content of 70.4% and reducing sugar content of 6.3%. The vitamin C was content was estimated to be 68.5 mg/100 g in the jujube pulp powder and the jujube pulp contained 6.2 g/100 g of dietary fiber. Major minerals were K, Mg, and Ca. After appointing jujube pulp powder (new method) to a test group and jujube pulp (traditional method) to a control group, the sensory evaluation and acceptance testing were conducted for yakbap, yakpyon, and jujube porridge. As a result, there was no significant difference in any sensory factors tested (p<0.05). It was found that making and storing jujube pulp powder by drying jujube pulp is a useful way of utilizing jujube because Yakbab, Yakpyun and jujube porridge were found to have a relatively good appearance, color, flavor, taste, texture and overall acceptance.

  • Objective: This study aimed to develop a value-added product concerning technological and sensory characteristics changes of the use of mechanically deboned poultry meat (MDPM) as meat replacer in lamb and mutton emulsion-type sausages (mortadella). Methods: Sausages were produced with lamb and mutton and with different contents of MDPM. Six treatments, using lamb or mutton and 0%, 30%, and 60% of MDPM in relation to the meat batter, were produced and analyzed for pH, proximal composition, calcium and residual nitrite content, water activity, 2-thiobarbituric acid reactive substances (TBARS), instrumental color and texture profile. The sensory profile of the mortadella's was also evaluated by acceptance test and check-all-that-applies (CATA) analysis. Results: The MDPM addition increased (p<0.05) fat, residual nitrite and calcium content in the all sausage formulations, but mutton sausage had (p<0.05) higher fat and lower moisture content than lamb sausage. The pH, water activity, TBARS index and color was not affected by MDPM additions, while the mutton sausages were significantly redder (higher $a^*$, $C^*$, and lower $h^{\circ}$) and darker (lower $L^*$) than lamb sausages. Adding up to 60% of MDPM reduced (p<0.05) sausages hardness and chewiness. Overall, the meat replacement by MDPM increased the sausages acceptance, but the mutton sausage with 30% of MDPM replacer were the most preferred. Consumers related that pink color, glossy appearance, poultry meat-like taste, soft texture, juicy and greasy mouth feel to all sausages contain MDPM according to CATA analysis. Conclusion: Mutton from culled ewes can be utilized for mortadella production with 30% replacement of lean mutton and fat by MDPM.

  • Salt-fermented fish and fish sauce are very important materials to make Kimchi. They provide good taste and plenty of nutrition to Kimchi during fermentation. However, it is difficult to purchase Korean salt-fermented fish or fish sauce out of Korea. Therefore, to generalize Kimchi for other countries, this research carefully compared the quality differences between Kimchi made with South East Asian fish sauce, which is fairly similar to traditional Korean salt-fermented anchovy extract (Aekjeot) in terms of taste and ingredients, and that made with traditional Korean salt-fermented anchovy extract. To determine quality differences among traditional Korean Kimchies made with different sauces, Korean-made salt-fermented shrimp, salt-fermented shrimp extract, salt-fermented anchovy and salt-fermented anchovy extract were used. Of the four Kimchis, the one made with salt-fermented anchovy extract was chosen as a control sample and compared with those made with three different South-East Asian fish sauces. In the sensory evaluation for acceptance of fish sauces, characteristics of taste, texture and overall acceptance showed significant differences. In the sensory evaluation for differences, characteristics of fish odor and crunchiness showed visible differences. For umami taste, all fish sauces received higher points than Korean salt-fermented anchovy extract (control sample), although the difference was not significant. Sensory evaluation and research results show that Kimchi can become a highly likable food overseas and Kimchi can substitute easily bought South-East Asian fish sauces for Korean salt-fermented fish sauces (Jeotkal).

  • This study was performed to determine the optimum ratio of each ingredient in the steamed foam cake with barley (Hordeum vulgare L.) sproutling powder. The experiment was designed according to the D-optimal design of mixture design, which showed 14 experimental points including 4 replicates for three independent variables (sugar 112${\sim}$139%, barley sproutling powder 1${\sim}$8%, and oil 5${\sim}$25%). The compositional and functional properties of test were measured, and these values were applied to the mathematical models. A canonical form and trace plot showed the influence of each ingredient on the mixture final product. The results of F-test, volume, color values (L, a, b), textural properties (hardness, gumminess, chewiness) and sensory characteristics (softness) decided a linear model, while the sensory characteristics (color, smell, taste, overall acceptance) decided a quadratic model. The volume of steamed foam cake was increased by sugar addition, and a negative effect was exerted by barley sproutling powder and oil. L and a of color values increased but the b value decreased with increasing sugar and oil content, whereas barley sproutling powder tended to decrease all color values. The addition of barley sproutling powder also had a positive effect on the textural properties (hardness, gumminess, chewiness). Sensory characteristics (color, smell, softness, taste, overall acceptance) could suffer counter results with the excessive addition of sugar, barley sproutling powder, and oil. The optimum formulations by numerical and graphical methods were similar: sugar, barley sproutling powder, and oil were 130.4%, 4.0%, and 10.7% by numerical method, compared to 130.4%, 4.0%, and 10.7% by graphical method, respectively.
