  • To establish the optimum formular for processing bread with steam-dried Hizikia fusiformis flour(SHF), it was incorporated into wheat flour by the ratio of 0, 1, 3, 5 and 7% based on a flour weight. Evaluation was performed on the rheological and sensory profile of bread, such as specific loaf volume, water holding capacity(WHC) and height, appearance and Hunter's color value, mechanical texture properties, and sensory value. Increase in the addition of SHF led to the tendency that the expansive force of dough fermentation reduced, and an increase in the textural properties of bread. And cohesiveness, gumminess, and chewiness indicated the tendency of a little reduction as influenced by adding more dried Hizikia fusiformis powder. As for sensory properties and flavor components of the white bread, in case of color and flavor, more than 3% of increase in the addition of the dried Hizikia fusiformis powder led to a drop in preference, and more addition led to a fall in taste and softness. Overall, it was found that adding less than 3% of dried Hizikia fusiformis powder is proper for dough in breadmaking.

  • The objective of this study was to investigate the changes in flavor components of cheonggugjang prepared with hazelnut. Amino nitrogen content in cheonggukjang was significantly lower in the 30~40% hazelnut group compared to the control group. The volatile basic nitrogen of hazelnut added cheongkukjang showed a similar pattern to that of amino nitrogen. The number of B. subtilis was slightly increased in relation to the amount of hazelnut added, but there was no significant difference. The content of glucose increased proportionally with increasing hazelnut. Total amino acid content decreased with increasing hazelnut. The ratio of glutamic acid to total free amino acids increased with increasing hazelnut. Oleic acid content increased proportionally with increasing hazelnut, while linoleic acid content decreased. In conclusion, the addition of hazelnut may contribute to the quality diversification of cheonggukjang by changing the taste and flavor while maintaining the amino nitrogen content of cheonggukjang.

  • This study aims to investigate the effect of the selection attribute of Newtro (New + Retro) product marketing, which is a recent topic in the food industry, on consumer satisfaction. Newtro marketing, also known as Newtro-style marketing, is a marketing strategy that emerged in South Korea, particularly in the food industry. Newtro marketing aims to appeal to consumers' nostalgia for the past while incorporating contemporary elements. As a research method, a survey was conducted on the importance of selection attributes and repurchase intention of Newtro food for consumer groups of various age groups ranging from teenagers to those in their 40s or older. To analyze the demographic content of the sample, frequency analysis of the SPSS statistical package was performed, and structural equation modeling was performed using the AMOS program for confirmatory factor analysis and discriminant validity analysis. The analysis results are as follows. First, Package Design, Perceived Healthiness, and Emotional Taste, optional attributes of Newtro marketing, significantly affected satisfaction. Second, satisfaction was found to have a statistically significant effect on repurchase intention. However, Functional Flavor did not statistically affect satisfaction. This study empirically analyzed the importance of consumers' selection attributes for the recently popular food Newtro marketing and suggested implications.

  • Objective: The objective of this study was to evaluate the effect of Debaryomyces hansenii isolated from dry-aged beef on the tenderness and flavor attributes of low-grade beef during dry aging. Methods: Five D. hansenii strains were isolated from dry-aged beef samples. The rump of low-grade beef was inoculated with individual D. hansenii isolates and subjected to dry aging for 4 weeks at 5℃ and 75% relative humidity. Microbial contamination levels, meat quality attributes, and flavor attributes in the dry-aged beef were measured. Results: Of the five isolates, the shear force of dry-aged beef inoculated with SMFM201812-3 and SMFM201905-5 was lower than that of control samples. Meanwhile, all five isolates increased the total free amino acid, glutamic acid, serine, glycine, alanine, and leucine contents in dry-aged beef. In particular, the total fatty acid, palmitic acid, and oleic acid contents in samples inoculated with D. hansenii SMFM201905-5 were higher than those in control samples. Conclusion: These results indicate that D. hansenii SMFM201905-5 might be used to improve the quality of beef during dry aging.

  • To provide scientific information for processing of value-added products from onion, volatile flavor compounds were compared in onions harvested in 6 regions, such as Muan (Jeonnam), Buan (Jeonbuk), Andong (Gyeongbuk), and 3 regions of Gyeongnam around Changnyeong (Yueo, Jangma, Seongsan). A total of 51 compounds were detected in samples by solid phase microextraction (SPME)/GC/MSD and they consisted mainly of sulfur-containing compounds (20), aldehydes (4), ketones (5), esters (11), aromatic hydrocarbons (4), nitrogen containing compounds (2), and miscellaneous compounds (5). The sulfur-containing compounds were the major compounds with ranges of $62.6{\sim}80.3%$ of total volatiles, regardless of harvested regions. The amounts of 5 sulfur containing compounds known as having antioxidant activity (2,4-, 2,5-dimetylthiophene, 2-vinyl-1,3-dithiane, 5-methoxy thiazole, and 3,5-diethyl-1,2,4-trithiolane) were the highest in Andong and followed by Yueo, Jangma, Buan, Seongsan, and Muan. However, onions from Buan region had the highest amounts of 5 sulfur-containing compounds known as having anticarcinogenic activity ((Z)-, (E)-methyl propenyl disulfide, (Z)-, (E)-propenyl propyl disulfide, and di-2-propenyl disulfide), followed by Yueo, Andong, Jangma, Seongsan, and Muan.

  • The objective of the current study was to evaluate the effects of roasting methods on volatile flavor compounds of boricha using solvent-assisted flavor evaporation-gas chromatography (GC)-mass spectrometry and GC-olfactometry. The barley roasting methods tested were air roasting (AR), drum roasting (DR), and air/drum roasting (ADR). Twenty, twenty-one, and eighteen aroma-active compounds were detected in the products of AR, DR, and ADR, respectively. Guaiacol (smoky), 2-acetylpyrazine (almond-like), and furfuryl alcohol (burnt sugar-like) were detected as high intensity aroma-active compounds. Intensities of most aroma-active compounds produced by the DR method were higher. On the other hand, aroma intensities of phenols produced by the AR method, such as guaiacol and 2-methoxy-4-vinylphenol (curry-like), tended to be stronger. Aroma characteristics of phenols are not considered to be desirable for boricha. Although roasting time for DR was longer than that for AR, DR may be an effective barley roasting method for enhancing desirable aroma characteristics of boricha.

  • In order to develop a dandelion (Taraxacum officinale) with natural food applications, the effects of dandelion leaves and roots powder content on the physical, textural and sensory properties of sulggidduk were examined. Dandelion powders of leaves and roots at 0, 1, 2 and $3\%$ were added to the dandelion sulgidduk. In the dandelion roots powder in sulgidduk, the color intensity of L values and the values and moisture content decreased however, the sensory color intensity, dandelion flavor and overall acceptability increased with increasing the dandelion powder content. The sensory overall acceptability indicated the dandelion roots powder content at 3% had the highest overall and flavor scores. As the dandelion leaves content was increased, the moisture contents, lightness, adhesiveness and cohesiveness of sulggidduk decreased, while the sensory color intensity, sensory hardness, hardness of texture properties and dandelion flavor increased. The addition at $1\%$ of the dandelion leaves powder content with the dandelion sulggidduk and the addition at $3\%$ of the dandelion roots powder content with the dandelion sulggidduk showed the highest overall acceptability.

  • Although the wine industry continues to grow, little empirical research on consumer preferences has been conducted. Thus, our objective was to analyze consumer views on wine attributes. A choice experiment (CE) was designed to detect a marginal willingness to pay for particular characteristics of wine (balance, flavor, color, clarity, and value-for-money). A questionnaire was administered and 286 responses were received. A multinomial logit model was estimated using the maximum likelihood method. The results indicated that balance, flavor, color, clarity, and price were all important to consumers. The CE data revealed that estimates of marginal willingness to pay were 31,899 won/bottle for balance, 23,088 won/bottle for flavor, 3,230 won/bottle for color, and 25,936 won/bottle for clarity. The balance of a wine was most important, and the flavor, clarity, and color were also significant. The results of this work will be of assistance in promoting the domestic wine industry.
