  • This study aims to analyze the sensory characteristic of cooked rice made with 10 types of rice varieties produced in South Korea using descriptive analysis. Twelve subjects who cook rice regularly, at least once a week, were recruited for the study and participated as descriptive panelists. A total of 29 descriptive terms were developed to describe the sensory characteristics of cooked rice. The findings showed that there were significant differences in the sensory attributes, specifically the appearance and texture attributes among the rice varieties. Among the varieties, Haedeul, Ilpum, and Koshihikari were observed to have a large quantity of rice germ and a relatively yellowish appearance. In contrast, Samkwang, Chamdream, and Yeonghojinmi were relatively whiter than the other samples. Odae, Saecheongmoo, and Sindongjin were rated high in the attributes of roughness, hardness, and chewiness, and Jinsang was rated high in moisture, bitterness, stickiness, and wholeness of rice grains. The differences in the appearance and texture of these rice varieties are likely to significantly impact consumer preferences. Furthermore, the development of customized menus based on the sensory characteristics of the different varieties of rice could encourage consumers to purchase these varieties.

  • 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 ($4.6{\pm}2.2/10$), salted seafood odors ($4.6{\pm}2.3/10$), offodors ($4.4{\pm}2.3/10$) and aftertaste ($5.9{\pm}2.1/10$) 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.

  • Arabica coffee is classified for trading according to the New York Board of Trade(NYBOT) green coffee classification. NYBOT's grading system is based on classification derived from a defect count on a 300 g sample. In the present study, green and roasted coffees were investigated for possible correlations between the content of defective beans and sensory characteristics. Sensory evaluation was performed by expert tasters used by the Specialty Coffee Association of America(SCAA) cupping method. For green coffee, the percentage of defective beans increased. as the coffee grade decreased. Black and sour beans were not found in the NY2 grade coffee out of all natural, pulped natural, and washed coffee samples. Sour and insect damage were found in more natural coffee samples as the green coffee grade decreased. Green and broken beans were found in more washed coffee samples as the green coffee grade decreased. Flavor, clean, uniformity, aftertaste, and overall sensory characteristics were significantly different among the NY2, NY3/4 and NY4/5 grade coffee in all natural, pulped natural and washed coffee samples. The natural coffee in the NY2 sample presented the highest body characteristic. The pulped natural coffee in the NY2 sample presented the highest sweetness and balance characteristics. The washed coffee in the NY2 sample presented the highest acidity and flavor characteristics. In conclusion, the percentage of defective beans increased as sensory characteristics decreased.

  • A kind of mineral water obtained from the basing of deep under the sea was reported to have a characteristic mineral composition and its effect on the quality of Kimchi was evaluated in this study. Kimchi samples were prepared with NaCl and the mineral water under rock floor as sources of salt together with fermented seafoods and fermented at 20 for 6 days. The qualities of Kimchi were evaluated by analyzing the pH, acidity, number of viable cell, lactic acid bacteria, sensory properties and texture profiles during fermentation. The pH and total acid contents were not different among Kimchi samples. The microbiological changes were not observed in the samples. The sensory scores of Kimchi containing NaCI and fermented sandlance sauce, and of Kimchi containing the mineral water under sea rock floor with fermented seafoods were significantly higher than those of the others. On the other hand, Kimchis prepared with NaCl alone or mineral water under sea rock floor alone earned the lowest sensory scores among the tested samples with an exception of firmness of the sample made with the mineral water. As the Kimchi fermentation proceeds, the hardness value of Kimchi prepared with the mineral water became higher than that of Kimchi with NaCl. This study suggests that the mineral water under sea rock floor could be useful to keep the texture of Kimchi firm during the fermentation.
