The object of this study is to investigate the relationship between the air dilution sensory test and the threshold odor number (TON) method for evaluating the odor of domestic wastewater, plating plant wastewater, food plant wastewater and lake water. The dilution factor of raw wastewater evaluated by the air dilution sensory test was in the order of food plant > plating plant > domestic > lake, and that evaluated by the threshold odor number method was in the order of food plant > domestic > plating plant > lake. The same results were obtained when the raw wastewater and lake water were diluted 2 and 5 times with pure water. The relative geometric standard deviation determined from the threshold values of each panel on the air dilution sensory test was much larger than that calculated from results derived from the threshold odor number method. The relative geometric standard deviation obtained from samples with a low dilution factor was greater. There was a very good linear correlation (correlation coefficient = 0.968~1.000) between the air dilution sensory test and the threshold odor number method. But, the reduction in odor intensity (the slopes of regression curves) by dilution was dependent on the types of the odor-emission sources.

본 연구는 돈육 중의 후지육을 이용하여 천연 향신료인 생강 및 인삼 분말을 첨가비율별로 처리(무처리 대조구, T1구(A-생강 분말 0.1% 첨가, B-인삼 분말 0.1% 첨가), T2구(A-생강 분말 0.2% 첨가, B-인삼 분말 0.2% 첨가), T3구(A-생강 분말 0.3% 첨가, B-인삼 분말 0.3% 첨가)하여 돈육포를 제조한 후, 저장기간에 따른 VBN, 미생물 수 및 관능평가에 미치는 영향을 조사하였다. 돈육포의 VBN 함량은 대조구와 처리구간에서는 통계적인 유의차가 나타내었고(p<0.01), 저장기간이 길어짐에 따라 VBN 함량과 총 세균수 및 대장균 수도 점차 증가하는 경향을 나타내었다. 또한 처리구에 상관없이 생강 분말 첨가군(A)이 인삼 분말 첨가군(B)군보다 유의적으로 낮게 나타났다(p<0.01). 돈육포의 관능평가의 경우, 육색과 맛은 처리구에 상관없이 저장기간이 길어짐에 따라 저장 2주째에 가장 높아 통계적인 유의차가 나타났고(p<0.05), 그 이후는 서서히 낮아졌다. 특히 육색의 경우, T1구의 A군이 다른 처리구보다 크게 높게 나타났다(p<0.05). 이상의 결과로 볼 때 돈육포 제조 시 생강분말 첨가는 미생물의 증식 억제에 다소 영향을 미치며, 육포제조 후 2주째에 가장 맛이 좋은 것으로 판단된다.

The objective of this study was to investigate the sensory quality attributes for the development of soy sauce containing an extract of the fruit of Hovenia dulcis Thunb (Hutgae), also known as liver function improvement and hangover removal. Aqueous extracts of Hutgae fruit and Hutgae fruit-soy sauce were used for determining the sensory evaluation. The intensity of the sweet smell and taste was predominated in the Hutgae fruit extract (p<0.05). Various seasoning items, such as apples, pears, dried figs, Korean bramble (Bokbunja), citron (Yuza) and sun-dried hot pepper (Taeyangcho), were used to determine the suitable type of seasoned soy sauce with the Hutgae fruit extract. In the sensory analysis, the highest overall preference (acceptance score 5) was obtained from the pear extract added to soy sauce with the Hutgae fruit. The overall preference of Yuza (score 4.9) and Taeyangcho (score 4.5) extracts also very well-matched the seasoning items for soy sauce with the Hutgae fruit extract. There was no difference among the extract mixtures of multi-seasoning items added to soy sauce with the Hutgae fruit extract. As more pear extract was added, a higher overall preference was obtained. On the other hand, as the more Yuza extract was added, the higher flavor intensity without the change of the overall preference was obtained. The overall preference of soy sauce with the pear- Yuza-Taeyangcho extract mixture was not different between with or without the Hutgae fruit extract. However, the overall preference (score 5.6) was significantly higher in the pear extract added to soy sauce with the Hutgae fruit extract compared with the pear extract added to soy sauce without the Hutgae fruit extract (score 4.8). These results suggest that soy sauce with the Hutgae fruit-pear extract mixture may be useful as a functional seasoning for various salad dressings.

Home-made soy sauces with or without Hovenia dulcis Thunb (Hutgae) originated from different parts such as fruits, stems, and twigs were prepared according to the Korean traditional procedure. Soy sauces supplemented with Hutgae were evaluated for their activities of 2,2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH) and alcohol dehydrogenase (ADH), free amino acid profiles, and sensory quality. All soy sauce types containing Hutgae had a strong DPPH activity as compared to the general type of soy sauce without Hutgae (GSC). Among Hutgae groups, DPPH activities of soy sauce supplemented with Hutgae stems was higher than that of soy sauces with either Hutgae fruits or twigs. ADH activities of soy sauces with Hutgae ranged from 14% to 55%, thus indicating that the functional activity of Hutgae was not altered during soy sauce preparations. Total free amino acid content of GSC was 295.5 ㎎%, and that of soy sauce with Hutgae fruits (346.8 ㎎%) was the highest when compared to Hutgae stems (272.3 ㎎%) and Hutgae twigs (225.6 ㎎%). In amino acid profiles, aspartate, arginine, histidine, and lysine levels were higher in soy sauces with Hutgae compared to GSC, whereas isoleucine, leucine, and phenylalanine levels were lower. Particularly, high levels of aspartate, glutamate, threonine, and lysine were presented in Hutgae twigs, whereas for Hutgae fruits and Hutgae stems, the levels of serine, glycine and arginine, and proline and methionine were high, respectively. According to sensory evaluations, Hutgae stems were preferred than GSC, due to the lower offensive smell and higher umami tastes. These findings demonstrate that soy sauce with Hutgae stems has potential protective effects against hangovers, improves the taste, and implies a possible functional ingredient.

The purpose of this study was to investigate the awareness, eating experience, and preference of kimchi, and the sensory evaluation of kimchi from Chinese and Korean students residing in Korea. General information (including age, sex, duration of staying, living status) was collected. A questionnaire was used to collect the information on awareness, eating experience, and preference of kimchi and dishes made with kimchi. Sensory evaluations were carried out on a 10 point scale. All subjects (37 Koreans, 43 Chinese) were aware of kimchi, with 98% of the Chinese subjects recognizing kimchi as a Korean traditional food and 65% having eaten kimchi at least once a day. The types of kimchi preferred by Chinese subjects were generally sweet and not over-bearing in seasoning, hotness, or ripeness. The more frequently eaten foods made with kimchi were jjigae, bokkeumbap, bibimbap and kimbap. However, the more preferred dishes made with kimchi were bossam, jeongol, bokkeum, jeon, and ramyeon. The Chinese subjects were especially sensitive to spicy odors (4.6±2.2/10), salted seafood odors (4.6±2.3/10), offodors (4.4±2.3/10) and aftertaste (5.9±2.1/10) compared to Korean subjects. Taken all together, the perception as well as sensory characteristic of kimchi needs to be improved for the globalization of kimchi.

This study aims to understand college students customer’s preference and the difference of coffee grade by comparing the result of Q-grader, who was trained professionally and received certification for a sensory evaluation of coffee grade. The results of the chemical analysis of raw coffee and coffee berry show that those of specialty grade had slightly higher, but not significant, water content. Further, the pH of specialty grade coffee was high in coffee beans and after roasting, the commercial grade became high. There was no significant difference between the specialty degree and commercial degree in color before and after roasting. In this study, the panels for the sensory evaluation included 24 university students. The preference of evaluation items of sensory evaluation consist of aroma, acidity, bitterness, astringency, aftertaste, and overall satisfaction. Items for the strength evaluation consist of aroma, acidity and bitterness. The sensory evaluation was expressed by applying a 5 point Likert scale (1: extremely low∼5: extremely high). In the sensory evaluation, it was evaluated that specialty grade coffee had strong acidity and commercial grade coffee was strongly bitter. The result of the sensory evaluation shows that female students are sensitive to coffee taste. In the analysis of frequent visit to coffee shop, the not-frequently-use-group rated that specialty grade coffee with higher overall satisfaction than commercial grade coffee in factors such as aroma and acidity. The group which did not prefer Americano coffee rated that specialty grade was higher than commercial grade in all factors except aroma, of which the result is similar to the cupping test.

The objective of this study is to investigate the sensory quality attributes for the development of soy sauce containing Cheongmirae (Smilax china) root. Aqueous extracts of Cheongmirae root and Cheongmirae-soy sauce were used for determining the antioxidant effect by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and sensory evaluation. Chengmirae-soy sauce was prepared by mixing Chengmiae extract (50%) and soy sauce (50%). Cheongmirae extract and Cheongmirae-soy sauce had strong DPPH scavenging effects, compared to that of general soy sauce. In sensory analysis, low intensities of smell, taste and overall preference were observed in Cheongmirae root extract. Various seasoning items, such as anchovy, dried-pollack, katsuobushi, shiitake, radish, and kelp, were used to determine the suitable type of soy sauce containing Cheongmirae root extract. The anchovy-kelp-radish and anchovy-shiitake kelp-radish among the seasoning items were well-matched with Cheongmirae root extract. From these results, soy sauce containing Cheongmirae root extract may be used as a soup seasoning for Korean style noodles.

This study was done to provide basic information about the storage and distribution of specialty grade coffee of which the market will be expanded through customer sensory evaluation according to the storage period of specialty grade coffee by the SCAA classified method with consideration to defective beans and scent. The specialty grade coffee sample of this study was extracted on day 1, day 14, and day 28. The water content showed a significant reduction on the 28th storage day and there was no pH change according to the storage period. Color degree was brightened according to the preservation period before and after grinding but there was no significant difference. The panels for sensory evaluation considered of 24 university. The sensory evaluation consist of aroma, bitterness, and astringency, acidity, aftertaste, overall satisfaction, and items for strength estimation consist of aroma, acidity and bitterness. The sensory evaluation was expressed by applying a 5 point Likert scale. The results showed that as the storage period increased so too did the aroma and the strength of bitterness. Preference was the highest on day 1 in every items except aroma and astrigency. However on day 14 and day 28, most of the sensory evaluation became low and then became high, which was inconsistent. Male students were not consistent in their evaluation according to the preservation period, but female students rated aroma and bitterness the lowest on preservation period day 1 and they prefer after a storage period of 1 day in regards to the entire degree of satisfaction including sour test. astrigency and aftertaste. The analysis of visiting frequency for coffee shops used demonstrated that the longer the preservation period, the lower the preference but was not significant in the case of involving a little frequency group. The group that did not like Americano coffee evaluated that the longer the preservation period, the lower the preference based on Americano coffee preference analysis. There was no consistency between the storage period day 14 and day 28 in strength and preference, but preference for storage period day 1 was high in every group, which means that the quality of coffee is affected by the preservation period.

The objective of this study was to investigate free amino acid composition, antioxidant activity, alcohol dehydrogenase activity and the sensory quality attributes for the development of functional soy sauce using Hutgae (Hovenia dulcis Thunb) fruit, which is well-known for improving liver function and alleviating various negative physiological effects following heavy consumption of alcoholic beverages. Soy sauces adding six types of extract from Hutgae fruit (HF) were prepared (SSH1: HF 20%, SSH2: HF 10%, SSH3: HF 20%/40 days NaCl extract, SSH4: HF 20%/20 days NaCl extract, SSH5: HF 20% water bath extract, SSH6: freeze-drying powder from HF 20% aqueous extract), compared with soy sauce using the conventional method. These soy sauces were used for determining alcohol dehydrogenase activity by NADH absorbance, the antioxidant effect by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and sensory evaluation by sensory scaling. Total free amino acid contents for most samples were in the range of 327.3 to 375.5 ㎎%, and then, aspartic acid and glutamic acid content of SSH1 and SSH5 were higher than that of others. DPPH radical scavenging activity was shown to be the highest in SSH4, also SSH1, SSH5 and SSF6 were shown to be higher than the control group. Alcohol dehydrogenase activity was shown to be the highest in SSH5. In sensory evaluation, the highest intensity of roast smell was observed in SSH4 while sweet taste was shown to be the highest in SSH5, and SSH3 and SSH5 revealed higher overall acceptability. From these results, Hutgae fruit soy sauces demonstrated antioxidant activity and alcohol dehydrogenase activity. In conclusion, soy sauces containing the water bath extract of Hutgae fruit may be used as a functional seasoning.

The objective of this study was to investigate the sensory quality attributes for the development of soy sauce containing Hutgae(Hovenia dulcis Thunb). Aqueous extracts of Hutgae were prepared from different parts such as trunk, twig, and fruit. These extracts were used for determining the antioxidant effect by 2, 2-diphenyl-1-picrylhydrazyl(DPPH) radical scavenging activity and sensory evaluation. Hutgae twig and fruit extracts had a strong DPPH scavenging effect compared to Hutgae trunk extract. In sensory analysis, high intensities of roast smell, bitter taste, and astringent taste were observed in Hutgae twig extract, whereas those of sweet smell and sweet taste were predominated within Hutgae fruit extract. Hutgae trunk and fruit extracts obtained higher overall acceptability. Various seasoning items such as anchovy, dried-pollack, katsuobushi, shiitake, radish, and kelp were used to determine the suitable type of soy sauce containing Hutgae extracts regarding the different parts. Hutgae fruit and trunk extracts were evaluated for use as a good source of seasoned soy sauce, and the dried-pollack and radish among the seasoning items were well-matched with Hutgae extracts. From these results, soy sauce containing Hutgae trunk and fruit extracts added to dried-pollack soup may be used as a functional seasoning in order to remove hangovers.
