“…The lowest average specific gravity was measured in acacia honey (1.430 g/cm 3 ), while the highest one (of 1.435 g/cm 3 ) was measured in linden samples. Quite close values, between 1.426 and 1.440 g/cm 3 , were found by Attri [50] in Indian honey and between 1.42 and 1.46 g/cm 3 by Ahamed et al [18] in honey from Saudi Arabia. Lower values were found, 1.40 g/cm, by [49] in Indian raw honey.…”

Romania is known among the main European honey producers, due to the variety of landforms as well as the diversity of the flora. Thirty-four honey samples of the acacia, linden and multifloral types, produced in eastern Romania and collected during 2013–2018, were physico-chemically analyzed using methods provided by the national and EU standards. The results of water-insoluble solids, color and refractive index were found to be 0.023–0.131%, 0.3–76.4 mm Pfund and 1.485–1.499, respectively. The moisture content ranged between 15.20% and 20.77%, solid substances content ranged between 79.23% and 84.80% and total soluble substances content ranged between 77.83 °Brix and 83.26 °Brix. The obtained values of specific gravity were from 1.414 to 1.450 g/cm3, pH ranged from 3.673 to 5.503 and free acidity ranged between 2.4 meq and 50 meq kg−1. The ash content and the electrical conductivity varied between 0.030 and 0.543% and 130 and 679 µS cm−1, respectively. Pearsonʹs correlation analysis showed an intense association of the ash content with electrical conductivity (r = 0.81). Our findings reveal the qualitative level of Romanian honey and the variation in quality parameters due to factors such as geographical region, climatic conditions, botanical origin and handling or storage conditions.

“…The gravimetric method was applied to assess the raw honey specific gravity, using the pycnometer device. Values were obtained by dividing the pycnometer mass (bottle of 50 mL) filled with honey by the mass of the same bottle, filled with distilled water [18,19].…”

“…Moisture content of both samples are similar to some local Indonesian honey reported (Adalina, 2018;Evahelda, Pratama, Malahayati, & Santoso, 2017;Savitri, Hastuti, & Suedy, 2017) and Indian honey which ranged from 22.6-26.2% w/w (Kavapurayil et al, 2014). The values obtained in this study were higher than rubber honey and rambutan honey from Indonesia (Harjo, Radiati, & Rosyidi, 2015), Nigerian honey (Buba et al, 2013), Algerian honey (Khalil et al, 2012), Saudi Arabia honey (Mohammed et al, 2017), and Pakistan honey (Ahmed et al, 2016).…”

Most of the local honey production in East Kalimantan is managed traditionally, thus honey quality, particularly its physical and chemical properties, are unknown. However, the honey analysis provides a comprehensive composition profile and potentially gives hints to improve the quality of local honey from East Kalimantan. This research aimed to analyse the properties of two local honey from East Kalimantan. The methods used in this study were gravimetric, volumetric, spectroscopy, spectrophotometry, and chromatography. Honey A was produced by Apis cerana whereas Apis dorsata produced honey B. The color intensities were 560±5.66 and 947.5±27.58 mAu for honey A and B, respectively. Honey A and B a had moisture content of 22.7 and 25.8% w/w, respectively. Other proximate analysis parameters were also reported. Fructose and glucose content for honey A were 30.65±2.35% w/w and 30.08±0.58% w/w, while honey B gave different pattern with fructose at 28.06±1.04 and higher glucose instead at 32.74±1.13% w/w. Reducing sugar and total sugar for both samples were higher than 60% w/w while sucrose in honey A and B were 2.8 and 1.4% w/w respectively, thus indicating no adulteration. Vitamin C content measurement showed negligible result with total phenolic content of honey A was lower than honey B. Honey B had higher Na, Ca, Fe and Zn than those of honey A. This study reported thorough chemical composition of local honeys from East Kalimantan in which some could have significant nutritional value. However, quality improvement particularly on moisture and reducing sugar content is necessary to meet Indonesian National Standard 8664:2018.

“…Concerning the effect of altitude on the physicochemical properties of honey, some previous studies reported the effect of altitude on some physicochemical properties honey such as the pH, conductivity, moisture, speci c gravity and acidity (Popov-Raljića et al, 2015;Mohammed et al, 2017). In a previous study, We have reported that the altitude signi cantly affected the concnetration of vitamin C in Acacia and Ziziphus honey samples in different harvesting season (Al-Mosa et al, 2019).…”

The altitude is well known to affect the temperature, parometric and oxygen pressure and the amount of UV radiation which affect the bees and the physicochemical properties of bee's honey. This study investigated the relations between the concentration of hydrogen peroxide, vitamin C and dicarbonyl molecules in honey samples from different floral origins and altitudes. Ten Ziziphus and twenty Acacia honey samples were collected directly from their bee farms. The hydrogen peroxide and vitamin C were measured using redox titartions while the dicarbonyl molecules concnetration was determined spectrophotometerically. The results were statisticaly analyzed by the ANOVA and t-test of the SPSS. The mean concentration of vitamin C in the Acacia and Ziziphus honey samples were 275.14± 82.3 and 239.16± 91.5 mg/100g, respectively. The mean hydrogen peroxide percentages in the Acacia and Ziziphus honey samples were 2.66± 0.81 and 4.94± 1.85%, respectively. The mean concentrations of the dicarbonyl molecules in the Acacia and Ziziphus were 324.62± 291.03 and 115.75± 94.9 mg/Kg, respectively. Significant variations were reported in the case of the hydrogen peroxide and the dicarbonyl molecules concentrations in the Acacia and Ziziphus honeys (p- values = 0.004 and 0.007, respectively). The altitude significantly afected the studied parameters. Honeys rich in dicarbonyl molecules have a high concentration of vitamin C and low content of hydrogen peroxide.
