기능성 꿀 및 그 생산에 대하여 관심이 있다면 우선 벌과 꽃과 꿀의 등식관계(벌=꽃=꿀)를 이해하고 벌꿀의 이용역사를 고찰하여 향후 이용 변화추위에 따라 소비자을이 선호하는 꿀을 생산하여야 할 것으로 본다. 인간에 대한 의학이 발달은 꿀에 대한 소비자들의 인식을 변화시키고 있으며, 건강 증진 및 장수를 위한 well-being 생활의 추구에 따라 식생활도 변화하고 있기 때문에 꿀에 대한 재평가가 요구되고 있다. 따라서 수명과 관련하여 건강증진에 유익한 기능성 꿀 생산은 매우 적절한 대응전력이라고 생각한다. 기능성 꿀벌 생산하려면 꿀에 대한 성분과 특성을 이해하고 기능성물질의 탐색과 더불어 벌을 통한 생산방법을 개발하여 가치 있는 기능성 꿀을 생산하여야 함으로 기능성 꿀 및 생산에 관한 정보를 제공하고자 한다.

In order to examine the quality attributes of native-bee honey, proximate composition and mineral components were analysed by atomic absorption spectrometry, ion chromatography and high performance liquid chromatography. The analytical results showed that native-bee honey is higher in the contents of crude ash, crude protein and diastase activity than those of foreign-bee honey. The principal mineral components of honey were Ca, Mg, Na, K and Cl, which showed that almost all the mineral components were contained higher in the native-bee honey than the foreign-bee honey samples. When we calculated K/Na ratio, we could make a clear distinction between native-bee honey and foreign-bee honey. The K/Na ratio turned out to be more than 10 in 6 samples of native-bee honey, whereas the ratio of foreign-bee honey showed up less than 1.5 in all 3 samples.

Various honeys from different sources were analyzed using an electronic nose based on a mass spectrometer. Various honeys were separated with different mixing ratios. Wild honey and artificial honey were blended at ratios of 100:0, 95:5, 90:10, 85:15, 80:20, 75:25, and 70:30, respectively. Data obtained from the electronic nose were used for discriminant function analysis (DFA). The DFA plot indicated a significant separation of honey from different sources. As the concentration of artificial honey increased, the first discriminant function score (DF1) moved from positive to negative (DF1: $r^2$=0.9962, F=490.6; DF2: $r^2$=0.9128, F=19.44). Furthermore, when acacia honey was mixed with artificial honey and separated with the mixing ratios, the DF scores were: DF1: $r^2$=0.9957, F=396.64; DF2: $r^2$=0.9447, F=29.3. When artificial honey was added to wild honey, it was possible to predict the following equation; DF1= -0.106${\times}$(concentration of artificial honey)+0.426 ($r^2$= 0.96). For acacia honey, the DF1= -0.112${\times}$(concentration of artificial honey)+0.434 ($r^2$=0.968).

We investigated and compared certain chemical properties of Korean natural honey and sugar-fed honey for assessing quality characteristics. The specification component was extracted using an organic solvent, and a single substance was isolated and identified as (E)-2-decenedioic acid. The content of (E)-2-decenedioic acid was $121{\pm}5.9mg/100g$ in sugar cane-fed honey and $127{\pm}4.5mg/100g$ in sugar beet-fed honey. Natural acacia, chestnut, and multi-floral honey contain $13{\pm}0.9$, $17{\pm}0.6$, and $13{\pm}1.3mg/100g$ of honey, respectively. Therefore, (E)-2-decenedioic acid was a major component of sugar-fed honey, however, it occurred in trace amounts in natural honey. We conclude that natural and sugar-fed honey can be distinguished by determining the (E)-2-decenedioic acid content.

To find out the difference between native bee-honey (NBH) and foreign bee-honey (FBH), quantification of honey protein and investigation of specific protein in NBH were carried out by SDS-PAGE. Contents of honey protein in NBH and FBH were measured by Bradford and Lowry method. The contents of protein determined by Bradford method were $0.1{\sim}3.3\;mg/g$ in NBH and $0.2{\sim}1.6\;mg/g$ in FBH, and by Lowry method were $12.9{\sim}45.7\;mg/g$ in NBH and $15.8{\sim}27.1\;mg/g$ in FBH. In order to investigate the distribution of bee honey proteins, the SDS-PAGE was performed. The results showed that molecular weight of the major proteins in NBH and in FBH were 56 kDa and 59 kDa. respectively. Therefore, it was confirmed that the difference between NBH and FBH can be identified visually by SDS-PAGE analysis. The major proteins in NBH and FBH were purified through two step chromatography, and the obtained proteins were used as marker protein in SDS-PAGE to discriminate NBH and FBH.

To compare the characteristics between native bee honey (NBH) and foreign bee honey (FBH), NBH harvested from eight different areas of Kangwon, Korea and FBH harvested from Chuncheon, Kangwon, Korea and from other nations were investigated by measuring the contents of moisture, sugar, 5-hydroxymethyl furfural (HMF), and pollen. Our results showed that contents of moisture in NBH and FBH were $16.4{\sim}23.0%$ and $15.8{\sim}21.0%$, respectively. Sugar contained in bee honey such as fructose, glucose, sucrose, maltose, and isomaltose were also analyzed. No difference were found between NBH and FBH in pH. The contents of HMF in NBH and FBH were $0.0{\sim}19.2\;mg/kg$ and $0.0{\sim}85.8\;mg/kg$, and was found that NBH is much lower than that in FBH. And production of HMF were accelerated by conditions of storage. Distributions of pollen in NBH were $0.4{\sim}88.3{\times}10^4/g$, which were significantly different from $0.0{\sim}0.4{\times}10^4/g$ obtained from FBH. According to those results, the methods used in this study are not suitable for identification of difference between NBH and FBH.

This study was carried out to investigate the quality characteristics of various honeys originating from different sources, and to identify factors potentially useful for distinguishing the honey sources. The sugar composition, moisture content and total acidity of twenty six honey samples were analyzed. The moisture contents were lowest in honeys from Acacia and were not greatly different with regard to honey sources. Fructose content was highest, followed by glucose, sucrose and maltose in all kinds of honey. Sugar composition did not show any reliable criterion useful for identifying the sources of honey samples. The fructose/glucose ratio did not differ among samples, however the ratios in honeys from Acacia and Chestnut were higher than honey from poly floral sources. The total acidity of honeys ranged 10.30-12.45 meq/kg regard-less of the source, thus acidity is not a useful criterion for identifying the honey source.

This study was conducted to analyze ash content, mineral composition, hydroxy methyl furfural (HMF) content, stable carbon isotope ratio, and SDS-polyacrylamide gel electrophoresis patterns to investigate the quality characteristics of various honeys harvested from different sources and to identify differences useful for distinguishing honey sources. Ash content was 0.046-0.012% in acacia honey, 0.565-1.318% in chestnut honey, 0.06-0.582% in polyfloral honey, and 0.237-0.893% in native bee honey. Potassium content was high in order of chestnut honey>native bee honey>polyfloral honey>acacia honey. The Na/K ratio was 0.92-1.97 in acacia honey, 0.02-1.59 in chestnut honey, 0.02-5.30 in polyfloral honey, and 0.22-0.51 in native bee honey. The HMF content was 9.60-12.85, 10.15-25.75, 9.7-33.5, and 6.25-21.5 mg/kg in acacia, chestnut, native bee, and polyfloral honeys, respectively. HMF content was the highest in native bee honey. A 59 kDa protein band was revealed in all samples by SDS-PAGE analysis. Protein bands of 32.1, 31.9, and 33.5 kDa were revealed in some chestnut honeys, and protein bands of 32.3 and 32.5 kDa were shown in native bee honeys. A protein band of 72 kDa was also confirmed in some chestnut honeys.
