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 purpose of this study was to investigate the intakes and perceptions of convenient breakfast related to age and family type. The survey included 545 men and women living in Seoul from June to July. Questionnaire items covered their age, gender, family types, breakfast intakes and preference for convenient breakfast menu. As a result, there were significant differences in the number of breakfast intakes per week according to family types; large families recorded the highest frequency in "I have breakfast everyday" and the couple-only families and nuclear families scored relatively high numbers. In terms of the type of breakfast, the first choice was "rice and side dishes" across all the age groups (69.3%). There were differences in the preference of convenient breakfast in "bread", "cereal", "rice cake", "sunsik", and "rice gruel" by different age. The teens exhibited the highest preference of bread (5.63), and cereal (5.53) for breakfast; those who were in their fifties for rice cake (5.42). Both forties and fifties showed the higher preference of sunsik (4.58, 4.76) and rice gruel (5.89, 5.77) than other age groups. As for the preference for convenient breakfast according to family types, single person families displayed the highest preference of bread (5.42) and cereal (5.75). Couple families showed higher preference of rice gruel (5.82) than other family groups. The preference level for "rice cake" was similar among all the family types. As a result, it is suggested that the development of various breakfast menus considering age groups and family types is needed so that modern people can enjoy breakfast in terms of quality and quantity in their busy daily life.

Food is essential for sustenance and reflects a country's identity, making it crucial to identify the cultural needs for effectively localizing Korean food. This study surveyed 825 adults from four continents (eight countries) to examine their preferences, familiarity, and attitudes toward Korean food. Significant correlations(p< .001) were found between the familiarity and preference for Korean food, with variations observed across continents. Among the representative Korean food items, the average preference score was 4.67, and the purchase/recommendation intention score was 4.88. Seven items received above-average ratings (e.g., gogi-deopbap and kimchi-bokkeumbap), while some items showed high liking but low purchase/recommendation intention (e.g. dak-jjim and galbi-jjim). In addition, items such as gimbap and tteokbokki had high purchase/recommendation intention but low liking, and kimchi and vegetable foods etc. received low liking and purchase/recommendation intentions. In terms of the preferred meat according to the cooking method and seasoning, beef respondents preferred grilled·stir-fried and soup·stew·hot pot cooking methods, while pork or chicken respondents preferred grilled·stir-fried and frying methods. Soy sauce was the most preferred seasoning for all meat responses, followed by red pepper paste. These research findings provide fundamental data for developing Korean food products, segmented by continent.

Therefore, we try to identify the factors that affect beverage consumption. According to the analysis of the demographic characteristics of male and female Chinese students, there were 155 male students (49.7%) and 157 female students (50.3%). There were statistically significant differences between the residence period and the time of coming to Korea according to sex (p<0.05), but there was no statistically significant difference between the education level, residence type and Korean ability (p>0.05). Analysis of the differences in health-related lifestyle among Chinese students of both sexes showed statistically significant difference in alcohol drinking, smoking, and exercise according to sex (p<0.05), but no statistically significant difference in computer use time (p>0.05). According to the analysis of the dietary habits of the Chinese students, there was a statistically significant difference in the number of meals per day, breakfast, lunch, dinner, snack frequency and number of midnight snacks, but no statistically significant difference in eating out frequency.

Mulberry pomace, a by-product obtained from mulberry juice, has not been utilized as a food material for food processing. In this study, the quality characteristics and antioxidant activities of chocolate to which mulberry pomace has been added were evaluated. Freeze-dried mulberry pomace was added to white chocolate at the level of 0, 0.5, 1.5 or 2.5%, and then the white chocolate ganache was put between two layers of dark chocolate. The moisture content and sweetness were not significantly different among treatments, but reducing sugar content was increased, according to the amount of mulberry pomace powder. The Hunter color L(lightness) and b(yellowness) values decreased, according to the mulberry pomace powder amount, whereas the a(redness) increased. The hardness increased according to the mulberry pomace powder amount. Total phenol and flavonoid contents increased, according to the mulberry pomace powder amount. Antioxidant activities(DPPH and hydroxyl radical scavenging activities) also increased, according to the mulberry pomace powder amount. The result of the sensory intensity test revealed that the scores of color, mulberry taste, hardness and chewiness were the highest in the 2.5% mulberry pomace powder added chocolate. Sensory preference test results showed that chocolate added with 1.5% mulberry pomace powder had the highest scores in color, flavor, taste, texture and overall preference. It is suggested that chocolate to which mulberry pomace powder has been added may be a functional chocolate, with high antioxidant activity.
