  • This study attempts to find optimum mixing proportion of rice dasik with yam powder by adding rice powder in different quantity and using honey and oligosaccharide as a sweetener. The results of the mechanical test and the sensory test on rice dasik are as follows. Moisture content of honey added one had less moisture than oligosaccharide added one did while having more sugar content than that. In color, honey added one showed the higher L-value and a-value than those of oligosaccharide added one, but it had the lower b-value. In hardness, chewiness, gumminess, and cohesiveness, oligosaccharide added one was higher. As a result of the preference test, the group which was added with 20% of yam powder was the highest. Based on the results above, adding yam powder makes the preference of rice dasik high, and the one added with 20% of yam powder is the best for rice dasik when using honey and oligosaccharide. This study used honey and oligosaccharide as a sweetening ingredient to make rice dasik, but it is necessary to research dasik with various sweetners and their different ratios.

  • The effects of the concentrations of Gardenia blue pigments and sugar types(honey and oligosugar) on the sensory quality characteristics of starch Dasik were investigated to develop a new blue colored starch Dasik. The blueness(-b value) was increased with the increase of blue pigment, while lightness(L value) was decreased. TPA values showed that hardness, fracturability, gumminess and chewiness were increased with the increase of blue pigment significantly(p<0.05), especially in honey-Dasik. In sensory evaluation, honey-Dasik with 0.04%-blue pigment showed higher scores than any other samples, especially in color, sweetness and overall acceptability, but was not significantly different.

  • Estimable taste constituents of the honey, e.g. amino acids, organic acids and sugars, were studied to evaluate the quality as well as the quantity of the honey obtained from several different origin. In the level of sugars and its components were very likely at all kinds of honey but sucrose amounts were slightly higher in feeding honey. Amino acids were highest in wild honey not only in its amount but its variety. Main components of the amino acids were found out as proline in feeding honey and in Tillaceae tree honey and as isoeucine in wild honey. Feeding honey demonstrates highest level of organic acids and the major constituents were oxalic acid and citric acid from wild honey, lactic acid from Tillaceae tree honey, and succinic acid from the feeding honey.

  • 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.

  • Background: Honey from different geographical origins can have distinct characteristics due to variations in the floral sources available to stingless bees in different regions. The most abundant stingless bee for meliponiculture in Thailand is Tetragonula pagdeni. However, only a few studies about the properties of honey from a different origin were carried out. The objective of this study was focused on a comparative study to evaluate the melissopalynological, physicochemical, antioxidant activities, and total phenolic contents (TPCs) of stingless bee honey produced by T. pagdeni from different parts of Thailand. Results: Fifty honey samples were collected from five locations, and the physicochemical properties of T. pagdeni honey samples are acidic (pH 3.02-4.15) and have a high water content (18.42-25.06 %w/w), which is related to the regions of meliponary. Melisopalynological analysis reveals the predominant pollen from Melaleuca quinquenervia, Cocus nuciferca, Nephelium lappaceum, Salacca wallichiana, and multiflora honey. All honey samples were analyzed for their TPC and 2,2-diphenyl1-picrylhydrazyl radical scavenging activity. The results show that all samples had high TPC and antioxidant activities with a strong correlation (p < 0.05). Conclusions: The data from this study indicates the importance of geographical origin, which links physicochemical properties, phenolic compounds, and functional characteristics to their floral. Besides, the floral sources and harvesting location affected the properties of stingless bee honey. Our results identify Melaleuca honey as a promising source of phenolic content and antioxidant activity that can be used as a functional food, as well as multiflora and Cocus honey. However, further studies are required to characterize the phenolic compound and its biological potential, which could be a stingless bee honey biomarker and quality control, simultaneously with the physicochemical analysis.

  • This study was conducted to develop a portable quality evaluation system of bee-honey by near infrared spectroscopic technique. Two kinds of bee-honeys from acacia and polyflower sources were tested in this study. The system consists of power supply, tungsten-halogen lamp, detector, and optical fiber probe. Performance of the system was analyzed by comparing the prediction accuracy of the laboratory spectrophotometer. Total of 346 spectra was divided into a calibration set and a prediction set. The PLS (Partial Least Squares) models were developed to predict the quality parameters of bee-honeys. Reflectance spectra, moisture contents, ash, invert sugar, sucrose, F/G ratio, HMF(hydroxy methyl furfural), and $C^{12}/C^{13}$ ratio of honeys were measured. The PLS models of the laboratory spectrophotometer showed good relationships between predicted and measured quality parameters of honeys in the wavelength range of 1.100~2.200 nm. The PLS analysis of the portable quality evaluation system showed good relationships between predicted and measured quality parameters of honeys in the wavelength range of 1.100~1.300 nm and 1.400~1.700 nm. The results showed the feasibility of the portable quality evaluation system to determine the quality parameters of bee-honey in the field during harvesting.

  • Honey is made from flower nectar by honey bees. In this study, 120 honeys from various flowers and across eight different provinces in Korea were collected and their components, antioxidants, and hemolytic activities against red blood cell were evaluated. Our results show that total polyphenol (TP) varied widely across the samples, with chestnut honey showing the highest TP ($77.1{\pm}8.4mg/100g$), protein content ($25.9{\pm}0.9mg/100g$), and absorbance at 400 nm ($A_{400}$ : $0.156{\pm}0.036$). In contrast, the acacia honey and sugar honey had a TP of 9.5~30 mg, 12~15 mg/100g of, and the lowest $A_{400}$ of $0.06{\pm}0.02$. High amounts of total flavonoid were quantified in the jujube and chestnut honeys at $8.73{\pm}7.31$ and $8.39{\pm}3.02mg/100g$, respectively. No samples demonstrated hemolytic activity up to 1 mg/ml. Antioxidant activities determined by DPPH, ABTS, and nitrite scavenging placed the chestnut honey highest, followed by jujube, styrax, multi-floral, citrus, acacia and sugar honey. Analysis of parameter correlations indicated that the components and bioactivity of the honey are dependent on the origin of the flower rather than on bee-farming regions. A positive correlation between TP content and antioxidant activity was identified. The correlation coefficients between $A_{400}$ and the TP, ABTS scavenging, and reducing power values were 0.804, 0.772 and 0.741, respectively. We therefore suggest that $A_{400}$ could be used as a noble, economic and simple factor for honey quality evaluation. Our results can potentially be used to develop functional honey for the food and pharmaceutical industries.

  • To compare the characteristics between native and foreign bee honeys, we analyzed several parameters of honeys by measuring pollen species, mineral content and K/Na ratio. Our results showed that native bee honey is higher in the pollen species, mineral concentrations than foreign bee honey. The K/Na ratio of native bee honey were increased 3.9~27.9 times than foreign bee honey. We could not detect Fe, Zn, and Al in all native bee honeys by the inductively coupled plasma method. The present results suggest that the several parameters such as pollen species, mineral content and K/Na ratio, were applicable for the identification of differences between native bee honey and foreign bee honey.

  • We investigated the effects of honey bee (Apis mellifera L.) colony size on the pollination of greenhouse-cultivated watermelon grown under the forcing cultivation system. The highest pollination activity of bees was observed ($14.3{\pm}5.0$ honey bees/day) when the bee colony size was 10,000 followed by 7,500 and 5,000 honey bees. There was a positive correlation between the bee colony size and pollination activity (R = 0.262) but insignificant difference in fruit set with different honey bee colony sizes (88%-91%). Evaluation of physical properties revealed that the weight and shape of watermelon were also not significantly different among different colony sizes. However, larger the bee colony size, higher the number of seeds were fertilized and rate of seed fertilization (p > 0.05). Number of seeds and content of sugar were negatively correlated (R = -0.714). Fertilized seeds showed a significant increase in mealy flesh, which has a negative effect on fruit quality, compared with that of the unfertilized seeds. Overall, we found that a colony size of 5,000 honey bees was the most effective for the pollination of watermelon grown under forcing cultivation. A comparison of the effects of bee pollination with those of artificial pollination suggested that artificial pollination can be effectively replaced by bee pollination in the forcing cultivation of watermelon, because fruit set, weight, and shape by bee pollination were similar to those achieved by artificial pollination.

  • Background: Dysmenorrhea is the most common menstrual complaint in young women with a prevalence as high as 90% and is responsible for substantial repeated short-term absenteeism from school and work in young women. The objective of this study was to compare the efficacy of Commiphora myrrha and honey with mefenamic acid in primary dysmenorrhea. Materials and Methods: This prospective standard controlled trial was conducted at Luqman Unani Medical College Hospital and Research Center Vijayapura, India where 40 diagnosed patients of primary dysmenorrhea were randomly assigned to receive test drug (powdered Commiphora myrrha gum resin10g with 30g honey in two divided doses) or active control drug (mefenamic acid 250mg TID) for first 3days of menstruationfor two consecutive cycles. The primary outcome measure was reduction in severity of pain assessed by numerical pain rating scale (NPRS), and secondary outcome measures were improvement in quality of life (QOL) assessed by SF-36 and reduction in perceived stress score (PSS). Results: During first cycle treatment no significant difference was found in NPRS score (p=0.085) between the groups however significant difference in NPRS score (p<0.001) was seen during 2nd treatment cycle. Significant reduction (p=0.022) in the perceived stress score was noted and overall quality of life was markedly improved after treatment in both the groups. Conclusion: These data suggest that Commiphora myrrha gum resin with honey is an effective herb in reducing symptoms of primary dysmenorrhea. These results need to be confirmed by a properly designed trial with a larger sample size. Trial registration: Clinical Trial Registry India CTRI/2017/09/009596.
