"Sujeonggwa" is a traditional korean beverage made from dried persimmon, cinnamon, and ginger and is often garnished with pine nuts. The purpose of this study was to investigate changes in the ingredients, recipes, and processing of "sujeonggwa" in Korean cookbooks published since 1400. The name sujeonggwa is derived from jeonggwa. In the early 1600s, sujeonggwa was used in ancestral rites and as a reception beverage, although we don't know its cooking method. According to the literature of the early 1800s, sujeonggwa was made from various fruit ingredients such as pear and yuzu. But since the late 1800s, it has been mostly made from dried persimmon based on ginger and cinnamon boiled with water. Garyeon-sujeonggwa is made with lotus leaf while japkwa-sujeonggwa is made with pear and yuzu. Japkwa-sujeonggwa is similar to hwachae in terms of ingredients and cooking method.

Sujeonggwa is a popular Korean traditional beverage. However, consumers only prepare it at home on special occasions due to the time and effort required. Developing a convenient form of Sujeonggwa may promote its consumption. The objectives of this study were to 1) develop Sujeonggwa in a tea bag using different sweeteners and 2) describe the characteristics of Sujeonggwa's flavor in tea bag samples and 3) determine how well consumers accept the tea bag samples. A total of four types of Sujeonggwa in a tea bag were developed: two samples with varying amount of sugar, another sample using sugar and stevia and the last sample using sugar and short chain fructo-oligosaccharide as a sweetener. A commercial ginger tea and cinnamon tea were used as control products. Descriptive analysis was conducted on the same six samples and a descriptive panel identified its attributes. A total of 61 consumers evaluated acceptability using a nine-point hedonic scale and how they felt about intensities of the samples using a just-about-right scale. The results indicated that consumers liked Sujeonggwa samples in a tea bag more than commercial ginger tea and cinnamon tea.

The recipe for sujeonggwa, a Korean traditional sweet drink containing cinnamon, ginger, sugar, or honey, was modified by replacing sugar with alternative sweeteners [stevia or short-chain frutooligosaccharide (scFOS)] in order to improve the health functionality of sujeonggwa. The aim of this study was to evaluate the effects of modified sujeonggwa on lipid peroxidation and oxidized DNA damage in diet-induced hypercholesterolemic ApoE knockout mice. Hypercholesterolemia was induced in 6-week-old male mice by administration of a high cholesterol diet (1.25% cholesterol, 0.5% cholic acid, and 10% coconut oil) for 4 weeks, after which mice were divided into five groups: sucrose solution-fed control group, sujeonggwa containing sucrose group, sucrose+stevia group, sucrose+stevia+scFOS group, and commercially available sujeonggwa group as a positive control. After 6 weeks, sujeonggwa supplementation resulted in reduced hepatic thiobarbituric acid reactive substances (TBARS), regardless of sweetener type. However, reduction of hepatic TBARS by commercially available sujeonggwa was insignificant. Both endogenous and $H_2O_2$-induced DNA damage in hepatocytes and splenocytes were significantly reduced only in the sujeonggwa containing stevia group compared to the sucrose-fed control group. There were no significant effects of sujeonggwa supplementation on total radical trapping potential, lipid peroxidation, or DNA damage in blood. These results suggest that sujeonggwa has protective effects against hepatic lipid peroxidation and DNA damage in hepatocytes or splenocytes from diet-induced hypercholesterolemic ApoE knockout mice, and the type of sweetener should be modified to improve the health benefits of sujeonggwa.

This study evaluated the sensory quality characteristics of gamma-irradiated Sujeonggwa a Korean traditional cinnamon beverage during storage, and the mutagenicity of the beverage. The minimum irradiation dose required to ensure the microbiological safety of powdered Sujeonggwa was 4.5 kGy. Sensory characteristics, and the Hunter's color value, of Sujeonggwa, deteriorated with increased irradiation doses, but no significant changes in sensory qualities were found during storage. The Ames test yielded no evidence that gamma irradiation induced mutagenicity in Sujeonggwa powder.

In this study, the hepatic lipid-lowering effects and related mechanism of action of sujeonggwa were examined in hypercholesterolemia-induced apoprotein E knockout (apo E ko) mice. Sujeonggwa drink was prepared with cinnamon, ginger, and sugar by modifying the traditional recipe of sujeonggwa. Sugar was partially substituted with either stevia or short chain fructooligosaccharide (scFOS) in order to reduce the calorie content of sujeonggwa, which was measured by descriptive analysis. Apo E ko mice (n=42) were induced to have hypercholesterolemia (plasma total cholesterol concentration >1,000 mg/dL) by administration of a high cholesterol diet for 4 weeks, followed by division into six groups. Experimental groups were orally administered water as a vehicle (normal group), sugar solution (control group), commercially available 'V' sujeonggwa drink (positive control group), or three different types of sujeonggwa drinks (S-sugar, S-stevia, and S-scFOS group) for 6 weeks while high cholesterol diet was provided to all animals. Compared to the control group, concentrations of hepatic triglycerides, total cholesterol, thiobarbituric acid reactive substances, and reactive oxygen species in S-sugar, S-stevia, S-scFOS were significantly reduced (P<0.05), indicating that sujeonggwa had inhibitory effects on hepatic lipid accumulation. Protein expression levels of fatty acid synthase (FAS) and its transcription factor, sterol regulatory element-binding protein (SREBP)-1 responsible for triglyceride synthesis, as well as 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) and its transcription factor, SREBP-2 responsible for cholesterol synthesis, were also reduced in S-sugar, S-stevia, and S-scFOS groups (P<0.05). These benefits of sujeonggwa were even greater in S-stevia and S-scFOS compared to S-sugar. The beneficial effects of S-stevia on regulation of hepatic lipid metabolism were slightly greater than those of S-scFOS although the differences were not significant. In conclusion, sujeonggwa drinks, especially functional sujeonggwa drinks in which sugar was partially substituted with stevia or scFOS, inhibited hepatic lipid accumulation via suppressing FAS and HMGCR protein expression through down-regulation of SREBP-1 and 2.

This study was conducted to develop the method for the safe supply of Sujeonggwa (cinnamon flavored persimmon punch) in severe environments such as space, desert or deep sea, by the combined treatment of gamma irradiation with other food technologies. Commercially prepared Sujeonggwa powder could be sterilized at 4.5 kGy or above doses. However, sensory characteristics of gamma-irradiated Sujeonggwa decreased depending upon the dose. The combined treatment of vacuum packaging with the addition of vitamin C and cinnamic aldehyde in Sujeonggwa powder could minimize the change of sensory qualities induced by ionizing irradiation.

The purpose of this research was to examine the preferences of five traditional Korean drinks and analyze the factors affecting the preferences of children aged 7-12 in Korea, Vietnam, and China. The samples used in a sensory test were omija-cha, yuza-cha, sujeonggwa, sikhye and misutgaru. The test was performed to examine the overall, appearance (color), odor, taste and mouth-feeling and a sweetness intensity using 5 point hedonic scale (1=dislike extremely, 5=like extremely) and, check-all-that-apply (CATA) method was performed to determine preference and non-preferences factors. The preference of all samples except sujeonggwa showed significant differences in all items of the preferences (p<0.001). Almost items of the preference was rated more than 4 points in Chinese and Korea children. The sweetness intensity showed also significant differences in all items of the preferences except sujeonggwa (p<0.001), and evaluated as not sweet-appropriate with the score between 2 and 3 points. Sweetness, color, mouth-feeling, familiar flavor and healthy feeling was selected for the factors affecting the preferences. In conclusion, the result of this study determine the preferences and the affecting factors for the traditional Korean drinks in children of Korea, Vietnam, and China.

This study selected and classified the representative foods for diversifying Korean traditional foods in the globa1 market and derived the superior factor of each food by consumer survey (n=744). The superiority of Korean traditional foods was generally recognized as being in the order of 'Nutritional value' > 'Dietary culture' > 'Material' > 'Taste.' Kimchi, Tteok/Hangwa, and grilled foods were regarded as potent Korean traditional foods for global consumers. The survey about the superior factors of representative Korean traditional foods produced the following results. The superior factor of Bibimbap, Mandu, Jangachi, Joeotgal, Namul muchim Salad, Naengchae, and Ganjang was 'Variety of material or cuisine', that of Bap, Jut Samguetang, Seolleongtang, Kimchi, Doenjang, and Sikcho was 'Nutritional value', that of Naengmyeon, Kalguksu, Bulgogi, Pyeonyuk, Jeongol, Gochujang, Tteot and Sjkhae/Sujeonggwa was Taste', and that of Hangwa, Hwachae, Gujulpan, and Sinsunro was 'Appearance'. The superior factors of representative Korean traditional foods showed the following differences by age and gender, The superior factor in Mandu was 'Taste' by the subjects aged below 30 but 'Variety' by the subjects aged above 30; that in Pyeonyuk and Jeongol was 'Variety' in 31-40 year olds and those aged above 51, while it was 'Taste' in others. The superior factor of Kimchi was 'Nutritional value' by the subjects aged below 40,'Taste'in 41-50 year. olds, and 'Variety' by the subjects aged above 50, that of Namul muchim was 'Nutritional value' by the subjects aged below 20 and 'Variety'by the subjects aged above 20, and that of Naengchae was' Taste'by the subjects aged below 20 and 'Variety' by the subjects aged above 20. The superior factor of Gochujang was 'Taste' by the subjects aged below 50 and 'Variety 'by the subjects aged above 50, that of Ganjang was 'Variety' by the subjects aged below 30 and 'Taste' by the subjects aged above 30, that of Sikcho was 'Variety' by the subjects aged below 30 and 'Nutritional value' by the sutjects aged above 30. The superior factor of Doenjang was 'Nuttritional value' in all ages. The superior factors of Hangwa and Sikhae/Sujeonggwa were 'Appearance' and 'Taste' in all ages, and that of Hwachae was 'Taste' by the subjects aged below 30 and' Appearance' by the subjects aged above 30. The perception by gender was statistically differed for traditional foods such as Bap, Bibimbap, Kalguksu, Bulgogi, Pyeonyuk Jangachi, Gochujang, Ganjang, Sikhae/Sujeonggwa, Hwachae, and Gujulpan.
