  • Hawthorn is widely distributed in Korea and has been used as herbal medicine for treating various cardiovascular disease, arteriosclerosis and hypertension in Korea. In order to select superior honey tree plant from Korea, the free sugar and organic acid in hawthorn fruits, including five Korean clones and four Chinese cultivars, were evaluated. We also compared these hawthorn fruits of five clones (selected from different area of Korea) with Chinese hawthorn cultivars. Glucose, galactose, fructose and sucrose were the major sugar components of hawthorn. In this study, we observed that sucrose, glucose and fructose content. The highest sucrose content of hawthorn fruit was 188.12g/100g in Daegeumseong cultivar. The sweetness index, which plays important role of taste, was also calculated from the content of sucrose, glucose and fructose. The contribution of each carbohydrate was calculated, based on the fact that fructose is 2.30 and sucrose 1.35 times sweeter than glucose. The highest sweetness of hawthorn fruit was 579.52 in Pocheon clone. Main organic acid detected in hawthorn fruit were citric acid, malic acid and shikimic acid. The highest citric acid and malic acid content in hawthorn fruit were 157.50g/100g (Pocheon 3) and 34.12g/100g (Daegeumseong), respectively. The results of this study would be helpful for using food and functional food products, due to the beneficial effects of free sugar and organic acid for human health such as antioxidants and anticarcinogenic properties.

  • This study was conducted to improve quality of takju where natural honey is used to control the ripening fermentation and the amount of sediment derived from takju mash. A koji was prepared using rice starch and Aspergillus awamori var. kawachii. Takju mash was prepared by alcohol fermentation with Saccharomyces cerevisiae and a 3-step addition of steamed rice. The clean part of the mash (CPM) was separated from the sediment at $5^{\circ}C$ and 5% (w/v) of natural honey was added and then ripened for 23 days at 5, 10, or $15^{\circ}C$. Temperature, pH, acidity, and total sugar content showed no significant differences, but a 0.2 percent reduction in alcohol content occurred during storage. However, CPM ripened with honey had a comparatively higher score on sensory evaluation than did immature CPM with added honey added. Takju with 8% alcohol content was prepared by mixing the water from the mixed CPM ripened with honey together with 100, 50, and 25% of the frozen sediment. Several quality characteristics of the takju were checked over 37 days of fermentation at $10^{\circ}C$. The pH was sustained between 4.1 and 4.3, and changes in the number of viable yeast cells, acidity, total sugar amounts, and alcohol content showed similar patterns but differences in scale. Smaller amounts of sediment affected the stability of the takju. Mixing the CPM ripened with natural honey at low temperature moderately reduced the amount of sediment in the mash and resulted in a highly flavorful takju with an extended shelf life.

  • Erythritol is a four-carbon sugar alcohol with a low calorific value and non-cariogenicity. Erythritol is a new functional sweetener which can be used as sugar alternative. Erytheitol dose not cause discomfort such as diarrhoea and flatulence upon ingestion. The purpose of this study is to develope a novel process of erythritol economically in a large scale. To obtain a high erythritol producer, we have screened 3500 colonies from molasses, honey and honey combs. We have selected 40 erythritol-producing microorganisms, one of which yields 140g/L erythritol in 40% glucose medium. We have tested this strain in 5L fermentor to examine the fermentation characteristics. Results of fermentation show that the erythritol production was about 1.4g/L$.$hr in 400g/L glucose media with a 42% conversion. Further improvements require mutation for a higher producer, process optimization to reduce glycerol, and suppression of excessive foaming.

  • This research investigates the quality characteristics of bread added with honey. The overall effects of honey on white pan bread were examined in terms of mixograph, fermentation rates, pH levels, TPA, colorimeter, water activity, hardness and moisture content of bread through different storage periods(1, 2, 3 days) using sensory evaluation. According to mixograph, all the samples were found to be proper between 3 and 5 minutes of peak time and their peak values were at the level of 60%. Also, HL100 had the highest fermentation rate and fermentation persistence from 60 min to 135 min. HL100 showed the lowest pH level in ingredient, dough, fermentation and crumb, and the highest specific volume. TPA analysis showed that HL100 had the lowest hardness and the highest springiness of all. And HL100 was the lowest in hardness(i.e. highest in softness) and had the highest moisture content after storage of 72 hours. Preference test showed that HL100 got the best texture, flavor, mouth feel, taste and overall acceptance. In these results of experiment, honey affects the quality of dough and bread, and liquid honey could be used as a substitute for sugar in breadmaking.

  • This work was aimed to evaluate supplementation of honey as sole carbon source on the fermentation characteristics of wine fermented with fruit of flowering cherry and honey(flowering cherry-honey wine). Physiochemical changes of flowering cherry-honey wine(2 L) were investigated during 30 days in fermentation by strain of Saccharomyces bayanus (EC-118). At the beginning of fermentation, fructose was most abundant sugar then glucose and sucrose were followed. As fermentation proceeded, utilization of glucose by S. bayanus (EC-118) was faster than fructose, so that the ratio of fructose/glucose was increased. During fermentation for 30 days, pH and viable yeast count was changed rapidly between 0 to 5 days, while $^{\circ}Brix$(%) decreased gradually for 30 days. Final total titratable acidity, pH, $^{\circ}Brix$(%) and ethanol content of flowering cherry-honey wine were 0.43%, pH 3.5, $9.7^{\circ}Brix$(%) and 14%, respectively. Our finding demonstrate that flowering cherry-honey could be benefical supplements for wine production.

  • In order to compare methods of making a mead and a melomel, changes of alcohol contents, reducing sugar, soluble solids, pH and total acidity during fermentation of a mead and Japanese plum melomel was investigated. Fermentation rate of the melomel were much faster than the mead. Reducing sugar and soluble solids were continuously decreased until the 16th day of fermentation, while alcohol contents were increased continuously during the same period. After fermentation of 21 days, alcohol contents of the mead was reached 7.6%, while that of the Japanese plum melomel reached 12.4%. pH and total acidity were not changed considerably during the whole fermentation period. Clear honey wines with transmittance of 99.4% were obtained by membrane filtration. In conclusion, the method of making melomel using the osmotically extracted fruit juice with honey was found to be more advantageous than the method of making a simple mead.

  • The purpose of study was to analyze secreted nectar volume, nectar sugar content and amino acid in addition to estimating honey quantities that can ultimately reap in male and female flowers of Evodia daniellii Hemsl.. The maximum blooming period of male flowers was on 24 to 26 July in 2012. On average, nectar volume secreted by nectary was $2.73{\pm}0.73{\mu}L$ from one male flower and nectar concentration showed 17.4%. The maximum blooming period of female flowers was on 7 to 9 August in 2012. Nectar volume secreted by nectary was $0.63{\pm}0.49{\mu}L$ from one female flower and nectar concentration showed 25.7%, averagely. As results of correlation analysis between the meteorological factors and nectar characteristics, we found that nectar quantities and concentration were influenced by temperature and relative humidity. Sugar content was calculated at $48.0{\pm}5.2{\mu}g$ per a male flower and $37.8{\pm}8.7{\mu}g$ per a female flower, which meant that both values were not significantly different (Mann-Whitney's U-test, p=0.400). The minimum estimates of honey harvest for a male and female inflorescence were 67.8 g and 53.5 g, respectively. Analysis of amino acid showed that Serine, Glycine and Alanine were more abundant in male flowers, however Asparatate, Glutamate, Asparagine and Glutamine were more abundant in female flowers.
