This study was performed to determine the optimal composition of muffins added with dropwort powder, egg and sugar. The experiment was designed based on BBD (Box-behnken design), and evaluation was carried out by means of RSM (response surface methodology), consisting of 13 experimental points with three replicates each for three independent variables dropwort powder, eggs and sugar. Using F-test, height, moisture, 1,1-diphenyl-2picriylhydrazyl (DPPH) radical scavenging activity, L-value, a-value, springiness, cohesiveness, chewiness, brittleness, color, and appearance acceptability were expressed as a linear model, whereas pH, b-value, flavor, taste, and texture were expressed as a quadratic model. After swallow and overall acceptability were expressed as a 2FI model. As dropwort powder content increased, 1,1-diphenyl-2picriylhydrazyl (DPPH) radical scavenging activity increased. Increasing amounts of dropwort powder led to reduction of sensory scores for color, appearance, flavor, taste, and texture quality. The optimum formulation determined by the numerical and graphical methods were similar: dropwort powder 6 g, egg 77 g, and sugar 60 g.

This study conducted a survey to analyze awareness, preferences, and the current state of consuming environmentally friendly organic food while eating-out in 435 adults aged 20 and above in Daegu, Korea. Most subjects (95%) showed awareness of environmentally friendly organic food, and 88.5% of subjects answered environmentally friendly organic food is ‘needed’. The percentage of eating out for families was 58.9%, and 49.0% of subjects said they eat out one to three times per month on average. In addition, subjects preferred a price range between 10,000 and 20,000 won per person when eating out, and they mostly favored Korean restaurants when ordering environmentally friendly organic food. Analysis of awareness of environmentally friendly organic food showed that among ‘health’ factors, ‘environmental’ factors, ‘social’ factors, and ‘dietary essential’ factors, ‘health’ factors showed the highest percentage for awareness. A survey on preferred foods by gender showed that both genders preferred vegetables the most. The results show that subjects in their 20s and 30s favored vegetables and fruits while subjects in their 40s preferred vegetables and grain animal products. Analysis of preferred types of environmentally friendly organic foods showed that men preferred polished rice while women preferred brown rice. Subjects in their 20s and 30s preferred strawberries, whereas those in their 40s preferred cherry tomatoes and those in their 50s and above favored tomatoes (p<0.001). Among root and tuber crops (63.4%), sweet potato was the most preferred. Among fruits, subjects preferred apples while among special crops, they most preferred oyster mushrooms; both genders preferred Korean beef. The most preferred livestock product of subjects in their 20s was pork, whereas subjects in their 30s preferred Korean beef. Subjects in their 40s preferred Korean beef and pork in the same proportions, whereas subjects in their 50s and above favored eggs the most.

This study was performed to determine the optimal composition of a muffin added with jerusalem artichoke powder and oligosaccharide. The experiment was designed based on CCD (central composite design), and evaluation was carried out by means of RSM (response surface methodology), which included 10 experimental points with three replicates each for the two independent variables jerusalem artichoke powder and oligosaccharide. The experimental muffin was prepared according to a traditional recipe, except that the flour was partially replaced by jerusalem artichoke powder (5, 15, or 25%) and the sugar was partially replaced by oligosaccharide (25, 50, or 75%). Using F-test, height, moisture, a-value, b-value, springiness, cohesiveness, texture, and overall acceptability were expressed as a linear model, whereas volume, pH, L-value, appearance, flavor and taste were expressed as a quadratic model. Increased amounts of jerusalem artichoke powder led to reduction of sensory scores for appearance, flavor, taste, texture, and overall quality. The optimum formulation determined by the numerical and graphical methods were similar: jerusalem artichoke powder 10.99%, oligosaccharide 71.40%.

This study was performed to investigate the qualities of jelly supplemented with purple sweet potato (C:0 g, P1:1 g, P3:3 g, P5:5 g, P7:7 g). The pH decreased (acidity increased) with the addition of purple sweet potato powder (p<0.01). The sugar content of the jelly also significantly increased when purple sweet potato was added. The DPPH radical scavenging activities of jelly increased as the addition of purple sweet potato increased. As the content of purple sweet potato increased, the L and b values decreased and the "a value" increased. In terms of textural characteristics, the addition of purple sweet potato increased hardness and springiness, while it decreased the cohesiveness. The results of the sensory evaluation showed that the appearance, flavor, taste, texture, and overall acceptability gave the highest score for jelly containing 5 g of purple sweet potato (P5).

This study was conducted in order to better understand the local and specialty foods of the Yeong-ju region. This study provides basic data for new menu development and commercialization. The results of 384 surveys, which were conducted to determine traditional rice cake production methods and their traits, were analyzed. Samgyetang was ranked top in the survey on recognition, public interest, and frequency of the local foods. Dakjuk was ranked second, followed by Baechujeon and Bopguk, in order. The levels of recognition and preference of specialty foods were in the order of hasuo, peach, apple, and meat. Among the answers in the survey on the popularization and commercialization of local foods, changing of the cooking style for younger generations' taste was considered to be the most important. Holding events to promote regional specialty foods and initiate the public to traditional cooking styles were listed sequentially by importance.
