Ⅳ. Results and Suggestions for Application of the Results
1. Results
The apicultural status of Korean native honeybee and the quality of honey produced from the Jiri Mountain area were investigated. The Korean native honeybee cultured around the Jiri Mountain were 122,470 colonies which corresponded to 33% of total native honeybee colonies cultured in Korea. In 5 provincial areas (Sanne, Namwon; Toji, Gurye; Cheongam, Hadong; Shicheon, Sancheong; Macheon, Hamyang) around Jiri Mountain, 54,504 colonies of native honeybee were cultured in 1,259 farm households.
Honey samples of Korean native honeybee collected from markets or apiaries were inspected for quality. Only 45 of the 162 honey samples, comprising 27.8%, were adequate for the Korea Beekeeping Association's quality standard of honey. The most lacking parameter from the standard was sucrose content (65%), followed by invert sugar (61%), which was thought to be due to inadequate supplement feeding. The excessive feeding of sugar solution results in production of low quality honey high in sucrose content. The supplemental sugar feeding, especially in the flowering season, was thought to lower the honey quality down, with high amount of sucrose and low amount of invert sugar.
In the present cultural system in our Country where the supplemental feeding is inevitable due to climate condition, feeding high quality supplemental feed such as honey would minimize the sucrose content in the stored honey. In addition, feeding fruit extracts in the flowering season may improve the honey quality, and further develop the fruit-fed honey as a high class brand product of added value.
As the quality of fruit extract for supplement feed is influenced by temperature, pressure and duration of heating in the processing of fruit extract, the optimum processing conditions were variable for fruits; 100℃, 1/kg for grape, 110℃, 2/kg for apple, pear and persimmon.
The fruit extract supplemental feed became fermented, being the pH lowered. The foam occurred during the fermentation interferes with sucking activities of honeybee. In addition, the fermented feed may lower the quality of honey stored. Therefore, the portion size of feeding is suggested to be controlled as such it is consumed all in 1-2 days.
The most favorable sweetness of supplemental feed, including fruit extract, was found to be 45-50%. Foraging activity of honeybee is highest at 30-50% of sweetness, and if various sugars were given, they are preferred in the order of sucrose, glucose, maltose, and fructose.
Supplemental feeding of fruit extract resulted in production of honey high in invert sugar and fructose. The fruit extract-fed honey was also high in organic acid content compared with commercial Korean native honey. These results suggest that supplemental feeding with fruit extract may improve honey quality by increasing invert sugar and may also enhance biological functions by incorporation of functional components from the fruits.
Concentrations of invert sugar and fructose in honey from grape extract-fed honeybee were dependent some on sugar sources, sucrose and honey, and some on sweetness. The supplemental feed with high sweetness (40-45%) produced better quality honey than that with low sweetness (25-35%). However, pH, titratable acidity, flavonoid, polyphenol, SOD-like activity and DPPH radical removal capacity of honey were relatively independent of the sweetness of supplemental feed.
Compositions of honey are divers as affected by various and complex factors, including colony size of bee, nectar and pollen plants in the foraging area and quality and quantity of supplemental feed. Although supplemental feed is not the only one, it must be an important factor to affect honey quality.
The quality of honey was quite dependent on nectar and pollen plants around apiary. The honey produced with no supplementary feed was not shown to superior significantly to that fed supplements.
Supplementary sugar feeding is thought to be necessary for maintenance and strengthening of the bee colony and production of honey. Timing and amount of the supplement feed are matters of beekeeper's technique, but the quality and hygiene of the feed are directly associated with the quality of stored honey.
Extraction of honey from comb honey by grinding was shown to be more efficient in collecting useful components from comb. When grinding method is used, moisture content is better to be lowered, and extensive grinding is preferable to obtain better quality honey.
Biologically active compounds in honey come from feed. The transfer of feed component to honey is in a complex association with nectar, stored honey and environment in hive. Changes in chemical composition during transferring feed component to honey are need for further studies.
Chemical compositions of stored honey were varied with fruits and sugars. When plum is used as supplemental feed, acidity of the feed was considered to be controlled.
SOD-like activity and DPPH radical removal of chestnut flower, green tea and plum extract-fed honey was shown to be affected much by their constituents rather than affected by extraction methods.
The characteristics of honey production by Korean native honeybee is the production of comb honey, which makes possible to utilize useful components in the comb. Therefore the native honeybee species may be superior to western (improved) species in production of functional honey.
Establishment of reserves for native honeybee farming, building up more bee forage for natural honey, organization of an association for exchange of information, improvement of hive and equipments, improvement of feeding system, research and development of bee-keeping technology according to behavior of bees, and development of good quality supplemental feed, such as fruit extracts, should be the urgent matters of calling for the growth of Korean native honeybee farming.
