The aims of this study recognize the limitations of the domestic chocolate market compared to domestic and foreign chocolate market and investigate the strategies for activation of the domestic chocolate culture and development of new chocolate market throughout pointing out the various problems. We analyzed the trends for the food market and confectionery market, main market for chocolate, and also compared domestic and foreign cases for market of chocolate as food or non-food. We sought for solutions and implications for diversification of domestic chocolate market through prospects for the future. Domestic chocolate market is not enough to be competitive compared with overseas market, yet. However, we speculated that domestic chocolate market would gradually develop through fusion with herbal bio-industry as rapid economic development. Besides, we demonstrated a few ways which derive larger development through combination of chocolate market and herbal bio-industry. For these sakes, we suggest that at first, if paradigm which is considered oriental medicinal characters and back innovative and differentiated ideas should be present, the activation of markets of chocolate and herbal bio-industry as well as the diversities of market may be obtained.

This study was conducted to determine the mixing conditions for Hibiscus syriacus L. chocolate depending on different addition ratios of Hibiscus syriacus L. and examine functionality in order to use Hibiscus syriacus L., which has excellent functionality and symbolizes Korea. To accomplish this, Hibiscus syriacus L. chocolate was manufactured by adding 0%, 2.5, 5, 7.5, and 10% of Hibiscus syriacus L. powder from the 'Samchulli' (Hibiscus syriacus 'Samchulli', which has reddish pink flower with red eye spot: SKK 14-2-72) variety to a coverture of white chocolate after which the antioxidant activity and quality characteristics were analyzed. As the amount of Hibiscus syriacus L. powder added to the chocolate increased, the chocolate color became darker, the pH decreased, and the sugar content and hardness increased. As a result of the sensory evaluation, the degree of preference increased as the amount of added Hibiscus syriacus L. powder increased to 7.5%. The degree of preference for color and flavor was the highest in the 5% added group, but the overall preference was 7.5% added chocolate. These findings demonstrate that adding Hibiscus syriacus L. powder to chocolate can increase chocolate functionality and preference and that there is a high possibility of Hibiscus syriacus L. chocolate development.

Purpose: The aim of this study was to investigate the effects of various leaf powders on chocolate by analyzing quality characteristics, antioxidant activities, and sensory characteristics. Methods: Pine needles, mulberry leaves, ramie leaves, barley leaves, and squash leaves were freeze-dried, powdered, and added to the chocolate. Results: Water contents of all leaf powder-added groups were significantly higher than that of the control (15.78%). The pH values of chocolate with leaf powder were lower than that of the control (6.33) while that of mulberry leaf chocolate (6.56) was higher than that of the control. In color measurement, L-value, a-value, and b-value were highest in pine needle chocolate (30.31, 3.52, and 4.78, respectively). The ${\Delta}E$ value (total color difference compared to white board) was the highest in squash leaf chocolate (69.51) and significantly different from that of the control (67.69). The hardness of leaf powder-added chocolate was lower than that of the control (6.84 N), except for pine needles. In the antioxidant activity analysis, chocolate with pine needles and squash leaves had higher polyphenols, flavonoids, and ABTS radical scavenging antioxidant activity than those of the control. Overall consumer acceptability was the most preferred in the control compared to the other groups. However, chocolate with mulberry and barley leaves also received high scores (5.60 and 5.40, respectively) for overall acceptability. Conclusion: It can be concluded that chocolate with barley leaves is desirable for making functional chocolate due to its high consumer preference and positive effects on improving antioxidant activities.

BACKGROUND/OBJECTIVES: Recent studies have reported chocolate consumption has beneficial effects on blood pressure, obesity, and dyslipidemia, which are components of metabolic syndrome (MetS). However, evidence regarding these relationships in Asia is limited. The aim of this study was to investigate relations between chocolate consumption and MetS in Korea. SUBJECTS/METHODS: Study subjects were 6,982 adults aged 19-64 years free of major chronic diseases that participated in the 2014-2016 Korea National Health and Nutrition Examination Survey. Information on chocolate consumption was obtained using food frequency questionnaires. For primary analysis, subjects were divided into two groups: non-consumer (n = 3,741, 53.6%); consumer (n = 3,241, 46.4%). In order to investigate dose-response effects on MetS, chocolate consumers were divided into quartiles based on amounts consumed: Q1 (n = 789, 24.3%); Q2 (n = 837, 25.8%); Q3 (n = 863, 26.6%); Q4 (n = 752, 23.2%) in second analysis. RESULTS: Chocolate consumers; 1) were more physically active(P < 0.0001); 2) less likely to smoke(P < 0.0001); 3) paid more attention to food nutrition labels (P < 0.0001), and 4) had healthier dietary patterns, that is, they consumed vegetables, fruits, and dairy products more frequently(P < 0.0001) than non-consumers. Furthermore, chocolate consumers had a 30% lower risk of MetS (odds ratio, 0.70; 95% confidence interval, 0.58-0.86; P = 0.0005). However, dose-response effects between chocolate intake and MetS was not found by secondary analysis after excluding non-consumers. CONCLUSIONS: In conclusion, chocolate consumers had healthier lifestyles and dietary patterns and a lower prevalence of MetS than non-consumers, as determined by our primary analysis. Although dose-response effects were not found to be significant among chocolate consumers during secondary analysis, the patterns were partially similar. This cross-sectional finding shows chocolate consumption does not increase the risk of MetS. The prospective studies and intervention trials in Korea are needed to confirm this cross-sectional finding.

In this study, we developed a 3D chocolate printer and studied the conditions needed for chocolate printing. Because chocolate is a mixture of cocoa mass, cocoa butter and sugar particles, its properties vary with temperature, and care is required in melting and extrusion. A chocolate supply unit is composed of a heating block and a syringe pump. It is integrated with a 3-axis linear robot. In order to be more accurate than the existing 3D chocolate printer is, the system was configured so that the printing line width became $430{\mu}m$. Printing performance was studied according to various parameters. The condition needed for printing lines with a stable width was discovered by the experimental design method and has been confirmed by a 2D line test. These 3D printing experiments showed that it was possible to build a 3D shape with an inclination angle of up to $45^{\circ}$ without support. Further, chocolate printing of a 3D shape has been successfully verified with the developed system.

With the continuous progress and development of the social economy, the importance of commodity packaging is increasingly manifested. It has become an important form of communication between businesses and consumers, and an important means of competition between businesses. The research scope of the thesis: First, through literature investigation, analyze the function of packaging design and consumers' buying attitude, and analyze the name, color, logo, illustration, etc. for general chocolate packaging and travel souvenir chocolate packaging. Research method: Through questionnaire survey, according to consumers' purchasing attitude and personal value of package design, we have in-depth understanding of consumers' purchasing power and package design's influence on purchasing conditions and research. According to the results of this study, first, from the perspective of general chocolate packaging and travel souvenir chocolate packaging to consumer consumption phenomena, general chocolate is more popular. Second, when consumers buy products, the taste of chocolate is more important than product packaging design. Third, in each product group, consumers value their own value when buying chocolate products. Fourth, due to the two important attributes of packaging design and taste, ordinary chocolate has a higher purchase intention than travel souvenir chocolate.
