  • Application of X-ray irradiation of dried condiments was studied using commercially prepared dried garlic, onion and welsh onion flakes as model samples. Total load of aerobic microbes (TAM), color differences, and generation of off-flavor were quantified for samples individually irradiated with gamma rays, electrons, or X-rays. TAM load was decreased by irradiation in a dose-dependent manner. The three types of radiation did not differ in the extent of TAM reduction (P>0.05). The samples did not differ in color. Off-flavor was detected from 6 kGy-irradiated samples, regardless of radiation sources. The results indicated that X-ray irradiation could be used for irradiation of dried condiments with the same effects as gamma rays and an electron beam.

  • Objective: This study aimed to elucidate the effects of cooking conditions on the physicochemical and sensory characteristics of dry- and wet-aged beef strip loins. Methods: Dry- and wet-aged beef aged for 28 days were cooked using different cooking methods (grilling or oven roasting)×cooking temperatures (150℃ or 230℃), and their pH, 2-thiobarbituric acid reactive substances (TBARS), volatile compounds, and color were measured. Results: Cooking conditions did not affect pH; however, grilling resulted in lower TBARS but higher cooking doneness at the dry-aged beef surface compared to oven roasting (p<0.05). In descriptive sensory analysis, the roasted flavor of dry-aged beef was significantly stronger when grill-cooked compared to oven roasting. Dry-aged beef grill-cooked at 150℃ presented a higher intensity of cheesy flavor, and that grilled at 230℃ showed a greater intensity of roasted flavor compared to wet-aged beef at the same condition, respectively. Conclusion: Grilling may be effective for enhancing the unique flavor in dry-aged beef.

  • The sensory quality and the baking property of blonds containing 10-50% of rice flour with wheat flour were analysed by QDA. As sensory characteristics, color, air cell size, air cell distribution, flavor, softness, chewiness and overall quality were evaluated. Bread could be made successfully even using up to 50% rice flour. The color, flavor, softness and chewiness were increased in rice-wheat bread especially using 10∼30% of rice flour, but in case of using 40∼50% of rice flour those characteristics were not significantly different from those of wheat bread. The size of air cell in 10∼30% rice-wheat bread was not significantly different but in 40∼50% rice-wheat bread it was increased. The distribution of air cell was more even in 10∼30% rice-wheat bread than in wheat bread, but not in 40∼50% rice-wheat bread. The overall quality of rice-wheat bread was shown to be better in 10∼30% rice-wheat bread than in wheat bread.

  • An investigation evaluating the preparation and physicochemical properties of sauce with various herbs(sancho, sage, and rosemary) derived from soy sauce was performed. The effects of the different kinds of herbs added to sauce for roasted mackerel were assessed using physiochemical, sensory, flavor, and texture analysis properties. This fish was then compared to, fish with salt. The moisture, crude protein, crude fat, and crude ash content of the roasted mackerel were significantly higher than the control(p<0.05, p<0.001). The salinity content of the herb sauce added samples were significantly higher than the control(p<0.05). Conversely, the pH and peroxide value of the herb sauce added samples were significantly lower than the control(p<0.001). A positive trend was observed for color value with sancho added sauce(p<0.001). The another positive effects on the texture of fish was observed for texture analysis, adhesiveness, springiness, gumminess, and chewiness with herb sauce added samples(p<0.05). In the flavor profile, the fishy smell was disappeared and antifungal flavor was improved with herb added sauce. Flavor, taste, texture, and overall preference of herb sauce were significantly highest in sancho added sauce(p<0.05, p<0.001). Results suggest that the best herb sauce for roasted mackerel was sancho added sauce.

  • This study was performed to determine the optimal manufacturing conditions adding green laver, which has a rich aroma and unique taste, to Sulgidduk. The variables in green laver Sulgidduk production were amounts of green laver powder and water. Six sensory characteristics were used for sensory evaluations, including color, green laver flavor, green laver taste, moistness, softness, and elasticity. The optimal amounts of the powder and water were found to be 6.84 g for green laver powder and 31.08 g for water, satisfying a target sensory score (7.0/9.0) according to a response surface method. Sulgidduk with these optimal amounts of green laver and water was tasted by 118 consumers and showed a high acceptability score (6.94). Older consumers ($\geq$30 years old) preferred the color and flavor of green laver significantly more than younger consumers ($\leq$29 years old) did (p<0.01). Color analysis results of green laver Sulgidduk were significantly different in brightness, redness, and yellowness from those of Sulgidduk (control)(p<0.01). Texture analysis scores of green laver Sulgidduk were significantly lower than those of Sulgidduk (control) in hardness, adhesiveness, springiness, cohesiveness, gumminess, and chewiness, and they were significantly different in adhesiveness and chewiness (p<0.05).

  • The objective of this study was to assess the quality characteristics of Sulggitteok prepared with different ratios of chestnut powder: 0%, 5%, 10%, 15%, and 20%. The moisture content of the chestnut Sulggi without added chestnut powder was 38.24% than that of any other chestnut powder added groups and gradually decreased from 33.34~26.27% based on the addition of chestnut powder. In terms of color, the lightness (L) decreased significantly but redness (a) and yellowness (b) significantly (p<0.001) increased with increasing contents of chestnut powder. The total polyphenol content and DPPH free radical scavenging activity increased as the amount of chestnut powder increased and decreased. Total phenol contents of phenol contents was higher in the 10% added group (347.50 mg GAE/100 g) and DPPH radical scavenging activity was significantly higher in the 5% added group ($69.35{\pm}2.02%$) and 10% added group ($74.33{\pm}2.29%$). Texture profile analysis showed that the hardness, adhesiveness, chewiness were higher than that of the control. The result of sensory evaluation test and the overall acceptability showed that the taste, color, flavor, chewiness, softness and overall acceptability were the highest in the 10% added group while the color and flavor showed no significant different group. Based on these results, it is suggested that chestnut Sulggi with up 10% added chestnut powder can be developed as products.

  • DPPH radical scavenging activities were 66.80% by hot water extract and 41.86% by 80% methanol extract. Inhibitions of angiotensin I-converting enzyme (ACE) were 91.09% by hot water extract and 75.20% by 80% methanol extract. In this study, Sulgidduk samples were prepared with 1, 3, 5, and 7% concentrated sweet pumpkin powder (CSPP), and a control were examined for quality characteristics such as moisture content, water activity, color, textural characteristics, and sensory qualities, in order to determine the optimal ratio of CSPP in the formulation. The samples containing CSPP exhibited significantly higher moisture content than the control group. Water activity was not significantly different among the Sulgidduk samples. For the color, the control group presented significantly higher lightness as compared to the samples containing CSPP. The samples containing 1 and 3% CSPP had significantly higher greenness than the samples containing 5 and 7% CSPP. Yellowness increased as the level of CSPP content increased. In terms of textural characteristics, hardness, gumminess, and chewiness were highest at the 1% substitution level, while lowest at the 3% level. The CSPP samples presented significantly higher adhesiveness, springiness, and cohesiveness than the control group. In the consumer acceptance and characteristic intensity rating test, the control group showed significantly higher color and flavor as compared to the CSPP samples. Pumpkin flavor, delicious taste, and off-flavor increased with increasing amounts of CSPP. Softness, overall acceptability, and gumminess were not significantly different among the various samples tested. Sweetness was highest at the 5% substitution level, while lowest at the 1% level. In conclusion, the results indicate that substituting $3{\sim}5%$ CSPP to Sulgidduk is optimal, providing good DPPH radical scavenging activity and inhibition of ACE as well as reasonably high overall acceptability.

  • Objective: This study aimed to investigate the effect of dietary supplementation with Allium mongolicum Regel extracts on the growth performance, carcass characteristics, fat color, and concentrations of three branched-chain fatty acids related to flavor in ram lambs. Methods: Sixty 3-month-old, male, small-tailed Han sheep were selected and randomly allocated into four groups in a randomized block design. Four feeding treatments were used: i) a basal diet without supplementation as the control group (CK); ii) the basal diet supplemented with 10 g/lamb/d Allium mongolicum Regel powder as the AMR group; iii) the basal diet supplemented with 3.4 g/lamb/d Allium mongolicum Regel water extract as the AWE group; and iv) the basal diet supplemented with 2.8 g/lamb/d Allium mongolicum Regel ethanol extract as the AFE group. Results: The results demonstrated that the dry matter intake was lower for the AFE group than that in other groups (p = 0.001). The feed conversion ratio was greater for the AFE than that in other groups (p = 0.039). Dietary supplementation with Allium mongolicum Regel powder and its extracts decreased the concentrations of 4-methyloctanoic acid (MOA) (p<0.001), 4-ethyloctanoic acid (EOA) (p<0.001), and 4-methylnonanoic acid (MNA) (p = 0.044) in perirenal adipose tissue compared to those observed in the CK lambs. Dietary supplementation with Allium mongolicum Regel powder and its extracts decreased the concentrations of MOA (p<0.001) and EOA (p<0.001) in dorsal subcutaneous adipose tissue compared to those in the CK lambs. The concentrations of MOA (p<0.001) and EOA (p = 0.002) in omental adipose tissue were significantly affected by treatment, although there was a tendency for lower MNA (p = 0.062) in AMR, AWE, and AFE lambs than that in CK lambs. Conclusion: This study demonstrated that Allium mongolicum Regel and its extracts could significantly promote feed efficiency, although dry matter intake decreased and could decrease the MOA and EOA concentrations related to characteristic flavor and odor of body fat in lambs, except for tail adipose tissue.

  • Raphanus raphanistrum subsp. sativus (radish) powder contains several bioactive com- pounds and is widely used in the food industry. In this study, we examined the sensory attributes (taste, color, flavor, texture, and overall acceptability) of commercially available milk, yoghurt, and kefir containing different concentrations of R. raphanistrum subsp. sativus powder. The organoleptic characteristics of commercially available milk, yoghurt, and kefir was significantly different with respect to taste, flavor, color, texture, and overall acceptability in the treated group (1%, 2%. 3%. and 4%) compared to the control (0%; p<0.05). In addition, the scores of taste, flavor, color, texture, and overall acceptability decreased in proportion to the increase in amount of radish-powder in commercially available milk, yoghurt, and kefir. When 1% R. raphanistrum subsp. sativus powder was added to commercially available milk, yoghurt, and kefir, they showed good results in organoleptic characteristics compared to the control group. Therefore, our results could be used as the basis for estimating changes in organoleptic characteristics on supplementation of various dairy products with R. raphanistrum subsp. sativus.
