  • In order to distinguish the honey in the market whether it is real or not simply and conviniently, the changes of water activity was investigated due to the addition of starch syrup and sucrose solution to the honeys such as Korean, Acacia, Chestnut and Mixed. The regression equations were obtained to predict the water activity of the honeys. In general, the honey was below 21% in moisture, below 0.6% in ash, 420 to 710cP in the viscosity, 0.57 to 0.62 in the water activity and 77 to 80brix in sugar content. The water activity of the samples were higher as the quantity of starch syrup and sucrose solution added increased. Starch syrup was more influence than sucrose solution. The regression equations between water activity and starch syrup concentration of honeys were obtained and $R^2$ value were higher than 0.90.

  • Among many honeys, the buckwheat honey was the best one using for Yackwa(a Korean cookie). We made a substitute, similary syrups of buckwheat honey, and then we got the following conclusions through the case of the similar syrups. 1. The best syrups are A, B and C syrup. A syrup's composition rate was sugar (40%), corn-syrup (20%) and water (40%) before boiling for 10 minutes. B syrup's composition rate was water (40%), glucose (20%), corn-syrup (20%) and sugar (20%) before boiling for 15 minutes. C syrup's composition rate like B syrup's but boiled for 10 minutes. 2. The best syrups used for dough are A and B syrup. C syrup was good for soaking. When A syrup used for dough, we have to immediate soaking in A syrup after frying or soaking in C syrup an hour later after frying. When B syrup used for dough, we must soaking in C syrup an hour later after frying. 3. The rate of fat in the composition of buckwheat honey's, A syrup's and B syrup's Yackwa was 27.22%, 23.05%, 23.05% and 30.35%.

  • Nosema spp. (NS) causes severe problems to honey bee colonies including the death of the highly infected ones. Searching for effective materials to control this parasite is very important. The objectives of this study were to identify the calendar for the prevalence of NS and other bee diseases, and to test the efficacy of three materials: diluted honey mixed with lemon juice (M1), chamomile extract mixed with sugar syrup (M2) and sutrivet mixed with sugar syrup (M3) against Nosema. To realize these objectives, diseases of brood and adult honey bees were surveyed over one year. Also, the efficacy of M1, M2 and M3 against Nosema was evaluated under field and laboratory conditions. The results showed that few diseases for immature and mature stages of honey bees were recorded. NS was detected during winter and spring in link with low temperature and high relative humidity. Under field conditions, M2 reduced the infection by 36.66% while M3 by 23.33% and finally M1 by 13.33%. In the laboratory, the highest efficacy was to M2 followed by M1 and finally M3. The three materials impacted the percentage of survived bees significantly higher than infected bees without any treatments over the experimental period. The study suggests the potential role of chamomile as a natural material to control NS.

  • The purpose of this study was to evaluate the effect of different saccharides on the quality of apricot sulgidduk. Appearance color of honey-added group as compared to other samples in apricot sulgidduk were preferable and scanning electron microscopy exhibited smaller pores. pH and acidity of white-added group immediately after preparation were higher than those of other groups. Higher moisture contents of honey-added groups during storage were found but total bacterial counts immediately before storage were 1 log cycle lower than that of other samples. The highest 'L' values were found for white sugar added group but the highest 'a' and 'b' were for yellow sugar-added sample. In mechanical characteristics of apricot sulgidduk for 48 hrs during storage at $20^{\circ}C$, hardness, gumminess and brittleness were higher in oligosaccharide-added sample as compared to other samples, while cohesiveness and springiness were the highest in honey-added group. In sensory evaluation of the sulgidduk, honey-added group obtained the highest score in color, sweet taste, moisture, after swallowing and overall quality (p<0.05) These results suggest that apricot sulgidduk with honey can be used as commercially successful rice cakes.

  • BACKGROUND/OBJECTIVES: The exposure to sucrose in rats has mimic abnormalities attributed to metabolic syndrome (MetS). The effects of honey bee and "free" glucose and fructose, have not been explored in this context. The aim was to expose Wistar rodents to sucrose solution (SS), honey solution (HS) and fructose/glucose solution (GFS) at 30% to assess their effects. SUBJECTS/METHODS: HS (n = 10), SS (n = 10) and GFS (n = 10) groups were formed. Solutions were ad libitum along 14-weeks. RESULTS: Between solutions consumptions, honey was significantly 42% higher (P = 0.000), while similar consumption was observed among GFS and SS. The feeding pattern of HS consumption was irregular along experiment; while the food intake pattern showed the similar trend among groups along time. Non statistical differences were obtained in any biochemical and anthropometric measure, however, a higher concentration of leptin (721 ± 507 pg/mL), lower concentration of total cholesterol (TC; 48.87 ± 2.41 mg/100 mL), very low density lipoprotein (VLDL; 16.47 ± 6.55 mg/100 mL) and triglycerides (82.37 ± 32.77 mg/100 mL) was obtained in SS group. For anthropometric values, HS showed less total adipose tissue (AT; average 26 vs. 31-33 g) and adiposity index (average 6.11 vs. 7.6). Due to sugar-sweetened beverages consumption increases the risk for the development of chronic diseases; correlations between fluid intake and anthropometric and biochemical parameters were assessed. A moderate correlation was obtained in groups with the weight of total AT and solution intake; for the weight gain in GFS group and for triglycerides in HS and GFS. The highest hepatic tissue damage was observed in SS group with multiple intracytoplasmic vacuoles, atypia changes, moderate pleomorphism and hepatocellular necrosis. CONCLUSIONS: In spite of the significantly higher consumption of HS, biochemical, anthropometrical and histological effects were not remarkably different in comparision to other sweeteners.

  • The rheological properties of seven mixed sugar solutions of glucose, fructose, maltose, sucrose, and two kinds of honey, the chestnut and the acacia, were discussed. The fluidity of the above samples were studied by using the applied pressure horizontal viscometer with which glycerine was confirmed to be a Newtonian flow at $25^{\circ}C$. Time required to pass the constant volume of the sample fluids through the capillary was measured at various pressure differences, ${\Delta}p$, and the ${\Delta}p$ vs ${\Delta}p{\cdot}t$ in the Poiseuille equation was plotted. Shear rate against shearing stress, on the other hand, was plotted for the sample fluids and it was found that all the sample fluids have shown a Newtonian behavior. It was interesting to note that the shear viscosity increased as the concentration of sugar solutions increased, and as the concentration of sucrose became higher than that of maltose, although the total concentration of sugar solution is constant.

  • The study explores the sensory properties of Backsulgi prepared with dry non-glutinous rice flour sweetened with various sweeteners(sugar, honey, oligosaccharide, trehalos, erythritol and accesulfame K). Sensory attributes of Backsulgi were evaluated by quantitative descriptive analysis(QDA), PCA and PLSR. The QDA results revealed that the sample sweetened with trehalose showed highest value in dryness, and samples with accesulfame K, honey and erythriol had relatively high levels in moisture and springiness. Principle component analysis (PCA) results showed 78.89 % of the total variation with PC1 (54.92%) and PC2 (23.98%), respectively. The samples with accesulfame K(AF) and honey, which showed high values in moisture level, springiness and sweet taste, showed similar attributes which led to a positive direction of PC1. The correlation between the sensory attributes and consumer acceptance showed that the most important factors for high consumer acceptance were moistness, springiness, sweet taste and sweet flavor. Overall, the samples with accesulfame K(AF) had the closest position in the PLSR results with highest overall consumer satisfaction.

  • The purpose of this study was to investigate the instrumental and sensorycharacteristics of Noralbyung made from rice flour and glutinous rice flour containing 1, 2, or 3% of ginger powder. The result of sensory evaluation showed that Noralbyung containing 252g rice flour, 45g (15%) glutinous rice flour, 3g (1%) ginger powder, 3g cinnamon powder, 55ml honey, 15ml water, and 3g (1%) salt had high overall acceptability and chewiness preference. From textural analysis, springinessand gumminess were increased by adding ginger powder. The Hunter color a-, L- and b-values of Noralbyung were all decreased by increasing the level of ginger powder. The moisture content (%) was higher in Noralbyung with sugar than honey. With increasing ginger powder content, the moisture content (%) of Noralbyung was decreased. From these test result, the most desirable recipe for Noralbyung was 252g rice flour, 45g (15%) glutinous rice flour, 3g (1%) ginger powder, 3g cinnamon powder, 55ml honey, 15ml water, and 3g (1%) salt. The moisture content was 37.72%.
