The purpose of the study was to assess the relative preference for hot & spicy sauces using conjoint analysis, with focus on English consumers. From the results of the study, we were able to derive a standard with the best sauce attributes. The respondent group was selected from the CCFRA's customer database. The qualification criteria for inclusion in the sample were: the primary grocery shopper in the household, a consumer of a range of home cooked oriental & far eastern cuisines, enjoyed hot & spicy chili-based foods, and willing to buy hot chili-based oriental sauces. A total of 676 respondents completed the survey in which 76% were women, and all respondents were between the ages of 18 and 65 years. An online survey method was used and a conjoint analysis was adopted. In conjoint analysis, a product is described as a combination of a set of attribute levels, where a utility value is estimated for each attribute level. In summing up the results of this study, the sensory property (flavor) attribute was most important, the second was brand, and the third was price. For the sensory property attribute, a mild chili sauce of blended garlic, sugar, and lime scored highest. In terms of brand, Blue Dragon was selected as the best. The lesser known Korean Kochujang brand of "Hot&Joy" scored lowest with respect to brand value. Encouraging, however, was the description based on the Hot&Joy product: a hot chili sauce blended with ginger and garlic, which held appeal across age groups and genders. In terms of price, 75p per bottle had the best score.

With the increased development of the dining sector, several restaurants have emerged and are becoming more advanced. Since the Michelin Guide Seoul publication in Korea, the fine-dining market has attracted attention from guests. Moreover, the number of customers visiting fine-dining restaurants has increased comparatively. However, it has been a mere 6 years since the publication of the Michelin Guide Seoul, and domestic materials and research related to the Michelin Guide are insufficient. Therefore, this research examines the factors responsible for restaurants to gain Michelin stars, and the effect of the Michelin guide on customers to select restaurants. Customers who have visited and experienced the star restaurants were interviewed, as well as the owner chefs and personnel managing the restaurant. The interviews were conducted from August to September 2020 using the Colaizzi method. The survey was designed to extract meaningful sentences or phrases from the participant interviews, categorize general and abstract statements into topic clusters, and describe the essential experience. This research aimed to determine the effect of the Michelin guide on customers for a selection of the restaurants and star restaurants. It is important to understand the development of Michelin restaurants and the effective factors which make customers choose the restaurants. Also, results of this study will be a future guide for the possibility of developing domestic fine-dining restaurants, normal restaurants, and the food service industry.

The aim of this study was to optimize the best recipe to make acorn bread containing milk as a functional food. The color value, textural, and sensory properties of the acorn bread added with 10~40% ratio of milk were measured to develop the best recipe. As a result, the L-value of color increased with the amount of milk added, but the a- and b-values decreased. As the textural measurement, the hardness increased with increasing milk added. Cohesiveness and springiness decreased, but the gumminess and brittleness increased with the addition of 20% milk, and decreased with further addition. The sensory evaluation revealed color, taste, and overall acceptances to have high scores at 20% addition of milk. Softness and chewiness were good at 10% addition. During the storage periods at room temperature, the L- and b-values increased with the addition of milk, whereas a-value decreased. In freezer storage, the L-value increased with milk content added, but the a- and b-values decreased during the storage periods. The textural properties increased during the storage at room temperature. The addition of milk decreased the cohesiveness and springiness, but the gumminess and brittleness increased significantly after one day storage. In freezer storage, all textural properties increased significantly during the storage periods, but the hardness decreased after two days storage. With the increasing amount of milk added increased the cohesiveness, springiness, and the gumminess except for four days, but decreased hardness and brittleness after two days storage. Therefore the addition of milk in acorn bread improved the textural properties significantly.

The purpose of this study was to investigate the microbiological characteristics and antioxidant activity of tomato sauce in terms of the variety of herbs that have been widely used in Western cuisine. As storage time increases, the number of total microbes changes, but the bacteria count was in the range of $1.0{\times}10^1-2.1{\times}10^2$, which did not increase much over 60 days of storage. The reason seems to be that the amount of heat treatment undergone by this type of sauce type, and its acidity make for difficult conditions for microbes to live. Yeast and mold measurements showed that yeast and mold were not detected for up to 30 days of storage in the tomato sauce with various types and amounts of added herbs. After 45 and 60 days, the yeast and mold count was in the range of $1.0{\times}10^1-8.5{\times}10^1$, and the same in the control. Measurements of phenolic compounds in 60 days of storage showed that tomato sauce with different types and amounts of added herbs had the lowest amounts relative to the control for all storage periods. The more herbs that were added, the higher the phenolic compounds resulted. As storage times increase, the phenolic compounds showed a tendency to decline. The DPPH radical scavenging effects of the tomato sauce herbs added showed a tendency to increase antioxidant activity when more herbs were added. The microbiology results of the storage test of tomato sauce with added herbs showed that the amount of microorganisms in tomato sauce with added herbs did not increase much in 60 days of storage at $4^{\circ}C$. The amount of microorganisms was small, so tomato sauce with added herbs can be used for 2 months with refrigeration.

This study was conducted to investigate the effects of saltwort, on the quality characteristics of sponge cake. In addition, we examined the commercialization potential of sponge cake containing saltwort. To accomplish this, saltwort was added to sponge cakes at concentrations of 0%, 3%, 5% and 7% and quality and sensory tests were then conducted. The 7% group had the highest water and ash content. There was no difference in the fat content between samples. The control group showed the highest protein content and the lowest specific gravity. As the content of saltwort increased, the specific gravity of the sponge cake increased. Additionally, the dough yield and loss during baking were highest, in the control group, and these values decreased as the saltwort content increased. Similarly, the volume and specific volume were highest in the control group, and these values decreased as the content of saltwort powder increased. Color measurements of the samples, revealed that the L-value decreased as the content of saltwort powder increased. Furthermore, the a-value of the saltwort powder groups was higher than that of the control group and the b-value was highest in the 7% group. There were no differences in elasticity and cohesion between samples, but chewiness and brittleness increased the content of saltwort powder increased. The results of the sensory test revealed that the color, flavor and taste scores were the highest in the 5% group. The pore size was greatest in the control group, while hardness was greatest in the 7% group, chewiness was highest in the 5% group and moistness was highest in the 5% group. Finally, the overall preference was for the 5% group.
