'백향(白香)'은 농촌진흥청 원예연구소에서 1978년에 천도 품종인 'Garden State'의 자연교잡종자로부터 유래된 백육, 만생, 이핵성 복숭아 품종으로 1991년부터 4년간 '원교 다-05' 계통명으로 지역적응성을 검토하여 1994년에 최종선발 및 명명된 품종이다. 이 품종은 모본인 'Garden State'를 닮아 산미가 적당하고, 향기 가 많은 감산조화형 품종으로 식미가 우수하다. 숙기는 백육계 복숭아로서는 가장 늦은 9월 상순이다.

This study was conducted to examine the sensory quality characteristics of Hobakjook (pumpkin porridge) samples prepared with 0%, 4%, 8%, 12%, 16% of waxy rice powder and non-waxy rice powder. The moisture content and spreadability decreased with the addition of waxy and non-waxy rice powder, while total soluble solid and viscosity increased with the addition of rice powder (p<0.001). The lightness (L-values) of Hobakjook significantly increased with the addition of both rice powder, but the yellowness (b-values) decreased. In the attribute difference test of sensory evaluation, yellowness, gloss, pumpkin flavor, sourness, smoothness and intensity of after-taste were amount-dependently decreased with the addition of both rice powders. However, sweetness, savory flavor, astringency, gelatinized rice flavor, and viscosity significantly increased as the amount of rice powder increased. The rankings of overall acceptance by consumers were 12% > 16% > 8% > CON (0%) & 4% for Hobakjook samples with waxy rice powder, while 8% & 12% > 16% > CON(0%) & 4% for Hobakjook samples with non-waxy rice powder. However, there was no significant preference between waxy rice powder and non-waxy rice powder.

참기름 중의 향기성분을 연속수증기증류법(SDE)과 동적헤드스페이스법(DHS)으로 포집하여 GC와 GC-MSD로 동정하였다. SDE로 분석하였을 때 alcohol 6종, aldehyde 6종, ketone 및 acid류 5종, furan 및 phenol류 4종, pyrazine 화합물 12종, pyridine 및 thiazole류 4종, 기타 9종으로 총 46종이 확인되었다. DHS로 분석한 경우 alcohol 3종, aldehyde 6종, ketone, furan 및 phenol류 6종, pyrazine류 12종, pyridine 및 thiazole 4종, 기타 5종으로 모두 36종이 확인되었다. 대부분의 화합물이 SDE법에서 분리된 것이었으나 1-hexanol, pentanal, dimethylsulfide등은 DHS법에 의해서만 분리되었다.

This study was carried out to develop character notes and to define the terminology for the evaluation of soybean curd using quantitative descriptive analysis. Panelists were selected according to their performance with ranking on basic tastes, flavor and texture properties related to soybean curd. After being trained, they identified the following attributes and defined the terminology: appearance(smoothness of the surface, amount of cracks, yellowness, grayness), flavor(sweet, salt and bitter tastes, cooked bean, raw bean, wet wheat flour, roasted bean, astringency), and textural properties(hardness, elasticity, inner moistness, coarseness, adhesiveness, and residuals). Reference samples for flavor attributes were also determined. Four types of commercial soybean curd were evaluated with the technique developed. Among soybean curd samples, there were significant differences in the intensity of all sensory attributes, confirming appropriateness of the evaluation methodology.

The purpose of this research was to appraise physicochemical properties by utilizing different Mit-sool, Juk, Seolgi-tteok, and Godubap, to produce traditional liquor. In all experimental plots, pH and amino acidity tended to increase with duration of fermentation. Titratable acidity displayed a very high number on the second day but then tended to decrease as fermentation progressed. Sugar contents were highest on the fourth day and tended to decrease with time. Alcohol content increased sharply at the initial stage of fermentation and increased gradually. On the 15th day, traditional liquor made with Godubap recorded the highest alcohol content. Common free sugar components were glucose and sorbitol. Common free organic acid components were lactic, succinic, citric, tartaric, malic, and acetic acids. Volatile flavor compounds were six alcohols, five esters, three aldehydes, and two ketones. Regarding overall acceptability in the sensory evaluation, traditional liquor using Seolgi-tteok as Mit-sool scored the highest. Overall, even though different types of Mit-sool had different physicochemical properties, there were no significant differences in volatile flavor compounds or sensory evaluation scores.

This study was performed to examine the effects of ${\gamma}$-irradiation on the volatile flavor compounds of dried leeks (Alliums tuberosum R.). Volatile compounds of dried leeks were extracted using simultaneous steam distillation and extraction (SDE), and analyzed by gas chromatography/mass spectrometry (GC/MS). Forty-one, 51, 45, and 42 compounds were tentatively identified in control, 1, 3, and 10 kGy irradiated samples, respectively. The constituents of flavor compounds in irradiated dried leeks were similar to non-irradiated samples. However, the intensities of the peaks were clearly different between them. Sulfur-containing compounds were detected as dominant compounds in all samples and their amounts decreased after ${\gamma}$-irradiation. ${\gamma}$-Irradiation reduced the total concentration of volatile compounds from leeks by 23.19, 15.09, and 30.23% at 1, 3, and 10 kGy doses, respectively.

In Korea, traditional doenjang is manufactured using the conventional method at home and by small-scale enterprises. Because this age-old process depends on natural inoculation of various microorganisms, it is difficult to reproduce or maintain consistency in the final product quality across batches. Moreover, doenjang occasionally prepared by this method raises safety concerns related to aflatoxin, biogenic amine, and Bacillus cereus contamination. To develop starters that can be conveniently used at home or in small industry settings for the manufacturing of safe and flavor-improved doenjang, autochthonous microbe starters were developed in dried forms as ready-to-use starters. Each starter powder prepared by heat- or freeze-drying methods remained stable even after 24-week storage. These ready- to-use starter powders were successfully applied to lab-scale fermentation for the production of safe and flavor-improved doenjang. We believe that these ready-to-use starter powders will benefit small-scale enterprises in the manufacturing of doenjang of good reproducible quality.

This study was designed as the precedent research to develop improve the HMR type flavored cooked rice, by analyzing the consumer perception and purchase pattern. This will in turn provide base data to that will help in the development of products that meet consumer's convenience and quality demands. An online survey of 247 people (63.5%) in the age of 20 to 60 was conducted on January 2019. For the primary reason of buying those products, the survey respondents chose a convenience of 71.7%. They are likely to buy 1~2 times a month (40.5%) in hypermarkets (63.6%). The channel choice showed meaningful difference between segments (p<0.01). 89.1% of respondents replied that they are willing to purchase frozen flavored cooked rice in the future. The Key Purchasing factor appeared to be the flavor (5.80), while nutrition (4.89) was chosen as the least important factor. For flavor preference, sea food received the highest score (5.05), while radish kimchi flavor received the lowest (4.02) with a meaningful difference by gender and age (p<0.01). Consumers who sought nutrition, convenience and adventure in HMR products had higher willingness to re-purchase. Developing healthy, flavorful, sensory, and enjoyable HMR products will be critical in the fulfillment of diverse consumer needs.

치커리의 적정 볶음조건 설정을 위하여 볶음조건에 따른 일반성분, 유리당, 갈색도, 가용성고형분 함량, 표면색깔 및 향기성분을 측정하였다. 각 온도별 적정 볶음조건은 $130^{\circ}C$에서는 30분, $150^{\circ}C$에서는 10분 그리고 $170^{\circ}C$에서는 3분이 가장 적당한 것으로 나타났으나 $150^{\circ}C$에서 10분간 볶음처리하는 것이 작업시간과 에너지 절약 측면에서 가장 좋은 것으로 나타났다. 가용성고형분 함량은 볶음온도나 시간에 영향을 받지 않았고 볶은 치커리의 유리당은 xylose 0.87%, fructose 0.62% 및 sucrose 0.84% 등 유리당 함량의 합은 2.33%였다. 치커리의 향기성분을 분리한 결과 23개의 주요 향기성분 피크를 얻었고 GC/MSD를 이용하여 이중 17개의 피크에 대하여 향기성분을 확인할 수 있었다. 확인된 향기성분을 분류하여 보면 aldehyde 화합물 5종, ketone 화합물 4종, pyrazine 화합물 4종, alcohol 화합물 3종 및 benzene 화합물 1종이었다.
