The of this study was to the abilities of Northeast Asians to discriminate sweetness on foods and their preference sweetness. Panels of Korean, Japanese and Chinese three sample -sucrose solutions, bulgogi, julienned radish salad- in which the sucrose levels had been manipulated to produce five samples of each. The sucrose solutions were prepared 1%, 3%, 5%, 7%, 9% sucrose to the water. Bulgogi and julienned radish salad 3%, 9%, 15%, 21%, 27% sucrose to the recipe. As, the three ethnic groups significant differences in test of sweetness in sucrose solutions(79%). Korean(a=1.164) to be the most sweetness, compared to Japanese(a=1.063) and Chinese(a=0.999). All ethnic groups preferred $3{\sim}7%$ solution, and Korean than Japanese and Chinese. Ethnic groups significant differences in sweetness of the julienned radish salad 21% sucrose. Korean(a=1.054) appeared to be the most able to detect the sweetness, compared to their Japanese(a=0.785) and Chinese(a=0.642). Both Korean and Japanese the strongest preference for the 15% julienned radish salad, the Chinese preferred the 21%. The abilities of ethnic groups to detect the sweetness in bulgogi significant differences high concentration(more than 27%), and the result of regression analysis on the awareness of sweet taste order Korean(a=0.918), Japanese(a=0.832), Chinese(a=0.690). All groups preferred the $9{\sim}21%$ bulgogi the most, Japanese showed higher preference 15% bulgogi than did Korean and Chinese.

Objectives : Chronic mild stress (CMS) model is currently recognized as a better animal model of depression. The purpose of this study was to investigate the antidepressant-like effects of the Nelumbo nucifera leave extract using CMS model. Methods : The antidepressant-like effects of Nelumbo nucifera leaves extract was determined by using animal models of depression. Male ICR mice were divided into four groups: saline-treated normal, without CMS; saline-treated stress control; CMS+ Imipramine(20mg/kg); CMS+Nelumbo nucifera leaves extract(200mg/kg). All mice except the normal group exposed an unpredicted sequence of chronic mild stressors for 5 weeks. The behavior of mice were detected by sucrose preference test, forced swim test and tail suspension test. Then concentration of corticosterone in serum was detected by enzyme immunoassay. Results : Nelumbo nucifera leaves extract administration by daily gavage from the 3rd week exhibited an antidepressant-like effect on CMS-induced depression in mice. Nelumbo nucifera leaves extract administration at dose of 200 mg/kg significantly increased the sucrose consumption, and decreased the immobility durations in forced swim test and tail suspension test. Furthermore the corticosterone level decreased than control group. Conclusions : Chronic mild stress can affect mouse behavior and corticosterone level and cause depression. The present experiments not only further confirm the antidepressant-like effects of Nelumbo nucifera leaves extract in the sucrose preference test, forced swimming test and tail suspension test, but also the improving effects of Nelumbo nucifera leaves extract on the depression-like symptoms in the CMS model. Nelumbo nucifera leaves extract has the antagonism on CMS and produce antidepressive effects.

This study was performed to know effect of Yackwa quality when sucrose fatty acid esters(S-570, S-970, S-1570) were added as an emulsifier. In mechanical characteristics, the Yackwa of sucrose fatty acid esters did greatly decrease the hardness, cohesiveness, springiness and gumminess, respectively, and increase the brittleness compared to the Yackwa of non-emulsifier and egg yolk. This tendency showed at the above level of 1.0% S-570, and 0.5% S-970 and S-1570, respectively. In sensory evaluation, the Yackwa of sucrose fatty acid esters increased the softness compared to the Yackwa of non-emulsifiers and egg yolk. There were significantly differences in the preference at 0.5% level of S-970 and 1.5% level of S-1570, respectively compared to other treatments. In conclusion, the 0.5% level of S-970 would be mostly useful level of emulsifier for making Yackwa.

Depression is one of the most common neuropsychiatric disorders and has been associated with the neuroendocrine system and alterations in behavior. Schisandra chinensis Baillon is one of major medicinal plants used as a Korea medicine and food sources, and has been processed in the fields of various food products and medicinal herbs. The chronic mild stress (CMS) protocol is widely used to evoke depressive-like behaviors in laboratory mice or rat. The CMS procedure induced some behavioral changes that are compatible with the common expectations, i.e. 'anhedonic' behavior and can affect corticosterone level. The present study, Schisandra chinensis extract administration by daily gavage from the 3 weeks exhibited an antidepressant-like effect on CMS-induced depression in mice. Schisandra chinensis extract administration at dose of 200mg/kg significantly increased the sucrose consumption, and decreased the immobility durations in forced swim test and tail suspension test. Furthermore the corticosterone level decreased than control group. In conclusion, Schisandra chinensis extract showed antidepressant-like effects on sucrose preference test, forced swimming test and tail suspension test based on CMS model.

This study was conducted to evaluate characteristics of bread and rheology of flour dough containing fructooligosaccharide. In the farinogram test, addition of fructooligosaccharide changed stability and development time. Stability and development time increased as the amount of fructooligosaccharide increased. In the extensograph test, the degree of extension decreased with increasing of fructooligosaccharide content, whereas degree of resistance increased. The volume of the loaf bread containing 10% fructooligosaccharide was the largest, and the bread containing 15% fructooligosaccharide revealed the best taste, flavor, and texture scores. After fermentation treatment, the volume of the dough with 20% of sucrose were less than that of 20% of fructooligosaccharide. Dough with 20% of sucrose revealed lowest dough raising power compared to other doughs. Overall, preference scores by sensory evaluation of bread containing fructooligosaccharide were higher than that of bread with sucrose. Therefore, excellent quality of bread may be achieved by adding fructooligosaccharide instead of sucrose to the process.

We investigate the effects of cryoprotectant mixtures on the quality of sand lance surimi (SLS) during storage at $-30^{\circ}C$. We monitored freeze-induced denaturation of myofibrillar protein in SLS and examined the texture profile of SLS gel. Freeze-induced denaturation was assessed by evaluating SLS $Ca^{+2}$-ATPase activity. SLS gels prepared with sorbitol or sucrose and a mixture of both as cryoprotectant. Higher concentrations of cryoprotectants resulted in significantly higher residual SLS $Ca^{+2}$-ATPase activity at the same storage time (P < 0.05). Residual $Ca^{2+}$-ATPase activity of SLS prepared with sorbitol was higher than that of sucrose when cryoprotectant concentration and storage period were same. A blend of sorbitol and sucrose resulted in a stronger cryoprptective effect of SLS myofibrillar protein than did sorbitol or sucrose alone. The presence of a phosphate compound in SOP (3% sorbitol + 0.2% phosphate compound) resulted in higher SLS $Ca^{2+}$-ATPase activity than that of did 5% sorbitol. The hardness, brittleness, and elasticity values and a folding test of the SLS gels were significantly affected by cryoprotectant concentrations and the storage time. Preference scores and acceptance for texture in a sensory evaluation of the SLS gels increased with increasing sorbitol or sucrose concentration.

Background: Dental fear and anxiety are significant challenges in managing behavior in children. Oral administration of sucrose or sweet-tasting solutions has shown effectiveness in reducing procedural pain in infants and neonates. This study aimed to investigate whether pre-application of sucrose solution had an effect on minimizing pain perception during injection and to assess the potential impact of the child's age and sweet preference. Methods: A randomized control clinical trial was conducted on 60 children aged 3-9 years requiring buccal infiltration injections. Following parental consent, demographic data of the children were recorded. Sweet preferences was assessed using a modified forced-choice test. Children were equally and randomly allocated into study (sucrose) and control groups using a lottery method. Sucrose solution or distilled water, respectively, was applied to the lateral surface of the tongue for 2 min. Topical anesthetic was applied at the site of injection, followed by local anesthesia administration. The children rinsed their mouths thrice with water immediately after anesthetic injection. A video was recorded during injection which was then scored by three blinded examiners on the Sound Eye Motor (SEM) scale. The children also self-evaluated using Wong-Baker Faces Pain Rating Scale (WBFPS). Results: The mean SEM scores and WBFPS scores were analyzed using the Kruskall-Wallis test. The mean SEM score in the study group was 1.37 ± 0.61, compared to 3.17 ± 0.87 in the control group, showing a statistically significant difference (P < 0.001). Mean pain scores assessed by WBFPS in the study group were 0.60 ± 1.4, while in the control group, they were 6.27 ± 2.33, also showing a statistically significant difference (P < 0.001). Children with a sweet preference demonstrated a subjective reduction in pain perception. Conclusion: Application of sucrose before dental injections in children helps to minimize pain upon injection across all age groups.

Objective : This study is conducted in order to investigate the effect of Banggibongnyeongtang(BBT) on Lipopolysaccharide (LPS)-induced depression. Method : LPS $5{\mu}g$ was injected to lateral ventricle. Experimental groups were administered BBT intraperitoneally. Depressive behavior was confirmed by weight change, sucrose preference, open field test(OFT), and forced swimming test(FST). The plasma concentration of $IL-1{\beta}$ and $TNF-{\alpha}$, Corticotropin-Releasing Factor(CRF), Adrenocorticotropin Hormone(ACTH) and Corticosterone(CORT) were measured by ELISA. Result : BBT did not change the body weight significantly than LPS group, but on sucrose preference, BBT increased significantly in LPS+BBT400 group compared to LPS group (P<0.05). In the OFT, BBT increased spending time in the central zone and decreased grooming number. LPS+BBT400 group increased central zone-spending time, and decreased grooming number than LPS group significantly (P<0.05). In the FST, LPS+BBT400 group decreased immobility time than LPS group significantly (P<0.05). BBT decreased $IL-1{\beta}$ concentration does-dependently, but only with significant decrease in LPS+BBT400 group than LPS group in plasma (P<0.05). But BBT did not decrease $TNF-{\alpha}$ concentration significantly in plasma. BBT decreased plasma CRF, ACTH, and CORT. And CRH and CORT of LPS+BBT400 group were shown significant decrease comparing with LPS group (P<0.05). Conclusion : It is postulated that the anti-depressant effect of BBT can be validated through inhibition of HPA axis abnormal activity by the anti-inflammatory effect.

This study was implemented to understand the motivation factors for $2^{nd}$ grade schoolchildren that effect on their preference for the sweet taste. The subjects included were 118 children (59 boys and 59 girls) and 118 children's guardians, from one elementary school. Children participated in sweet preference test and questionnaire survey with researcher's guidance provided in the school. Children's guardians were asked to fill out the questionnaire via home-letters. The results were as follows: 59% of the children preferred the cocoa beverage with the highest concentration of sugar among five cocoa beverages (0%, 2.5%, 5%, 7.5%, and 10% of sucrose/milk volume). The variables consisted of affective attitude, cognitive attitude, self-efficacy, parenting style, and sweets frequency. According to the analysis, sweet preferences were correlated with children's affective attitude (r=-0.207, p<0.01), self-efficacy (r=-0.288, p<0.01), frequency of drinking carbonated beverage (r=0.272, p<0.01), preference for yogurt (r=0.184, p<0.05), and preference for sweet bread (r=0.226, p<0.05). These results indicated that children can be more affected by affective attitude than cognitive attitude, and self-efficacy can be an important motivation factor to control the eating behavior related to sweets. Therefore, nutrition educators need to focus on developing various methods related to increasing self-efficacy for encouraging and motivating healthy eating behavior in children.
