  • The contents of reducing sugar, sucrose, starch and fructose-2,6-bisphosphate (F-Z,$6-P_2$) in relation to the activities of amylase, invertase and fructose-1,6-bisphosphatase (FBPase) were investigated from the leaves of rice (Oryza sativa L. cv. Samjin) seedlings grown at $4^{\circ}C$ for 3 days_ In the seedlings, the contents of reducing sugar and sucrose were increased, but soluble and insoluble starch were declined. Under this condition, amylase activity was increased. but acid invertase activity was declined and alkaline invertase activity was not changed. Cytosolic and stromal FBPase activities were increased. But F-2,$6-P_2$ content was declined. It seemed that the increase of reducing sugar content might be due to the increased activity of amylase and the increase of sucrose content might be related to the increased activity of cytosolic FBPase, reduced content of F-Z,$6-P_2$ and reduced rate of hydrolysis of sucrose during the cold treatment. These results suggested that the changes in carbohydrate rnetabolim of rice seedlings under low temperature reflect one of the protection mechanism to the low temperature during the cold treatment.atment.

  • Purpose : Infantile colic is one of the most commonly encountered problems, characterized by excessive crying in apparently healthy young infants within the first 3 months of life. It is commonly assumed that the infant with colic has distress and possible pain. In recent investigations, it has been found that sucrose has an analgesic effect in newborn infants. The purpose of this study is to examine if sugar solution as sucrose also has an analgesic effect on infant colic. Methods : This prospective randomized, double-blind placebo controlled study examined healthy term infants aged 4 to 12 weeks with colic. A total of 40 infants were randomly assigned into two groups who visited Daedong Hospital from June 1999 to June 2001. Each group received sugar solution or sterile water. All data from parental diaries and interviews were recorded and analysed blindly. Results : The daily crying time and the colic improvement score were significantly better in sugar solution group as compared with the control(P=0.019, 0.045). No significant differences were noted between groups regarding the number of night wakenings(P=0.173). Conclusion : We conclude that sugar solution has an analgesic effect on infantile colic.

  • 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.

  • Allulose, a monosaccharide isomer of fructose, was evaluated as a sucrose replacer for healthy cookie production with benefits such as low glycemic impact and low calorie content. Sucrose (as a reference), fructose, glucose, and allulose were used to explore the effects of sugar-replacer type on solvent retention capacity (SRC), differential scanning calorimetry (DSC), rapid visco-analyzer (RVA), and wire-cut cookie baking. SRC results indicated the lowest swelling of solvent-accessible arabinoxylans in allulose compared to that in other sugar solutions. DSC and RVA results showed retardation of starch gelatinization and onset of starch pasting, respectively, in the following order: water < allulose < fructose < glucose < sucrose. Among sugars, wire-cut cookies formulated with glucose showed the least desirable attributes with respect to cookie diameter and thickness. Although the baking response of allulose was slightly inferior to that of the sucrose control, the sugar exhibited a superior baking response to that of fructose, suggesting it could be used successfully as a fructose alternative or sucrose alternative for producing wire-cut cookies with reduced calorie content and low glycemic impact.

  • This study investigated the effects of Stevia rebaudian bertoni leaf extract on lipid profiles in C57BL/6J mice, as compared to stevioside. Fourty mice were divided into four groups: NC (normal diet and DW), HC (high fat diet and DW), HLSV (high fat diet and stevia leaf extract, 1 mL/kg/day), and HSS (high fat diet and stevioside, 1 mL/kg/day). Serum triglyceride concentrations were significantly lower in the HLSV and HSS groups than in the HC group. Epididymal fat pad weights were significantly lower in the HLSV and HSS groups than in the HC group. We also evaluated the serum and liver carnitine levels (NEC, AIAC, ASAC, TCNE) of all the groups. These results were supported by the mRNA expression of enzymes related to lipid metabolism (ACC, PPAR${\alpha}$, ACS, CPT-I) assessed by RT-PCR. Overall, the results show the antiobesity effects of stevia leaf extract as compared to stevioside in high fat diet induced obese mice.

  • The antimicrobial activity of the extract of citrus peel prepared by the method of hot water, ethanol and sugar was examined. The results showed that the extract of citrus peel prepared by hot water or ethanol did not have antimicrobial activity, but the extract by 10$\%$(w/v) sugar revealed the high antimicrobial activity. Extracted in 10%(w/v) sugar solution for 9 days, showed the highest antimicrobial activity against 8 strains of bacteria. The minimum inhibition concentration was found to be 0.5$\%$(v/v) against S. aureus, 1.5$\%$(v/v) against B. subtilis, M. luteus and E. coli, and 2.0$\%$(v/v) against S. mutans. The antimicrobial activity of the citrus peel extract was stable regardless of the treatment at 40 $\~$ 100 $^{\circ}C$C for 20 min and unstable response to the change of pH. The results suggested the development of citrus peel as heat-stable antimicrobial agents.

  • 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.
