“…Distilled water was used as a blank and relative humidity was maintained at 21.0%. The outlined sample preparation procedure and analytical measurement were adopted from the works of Formicki [5] and Aldgini [6] with slight modifications. In the earlier procedures, complete dissolution of samples is achieved under the action of acid at 90100 o C. A five-point calibration graph was created for each element.…”

“…In small amounts, propolis samples contain a range of mineral compositions. The mineral components of honey, propolis and bee pollen depend on the source plant and region [5] . Metals that are derived from soil, carried to plants that produce nectar through their roots, conveyed through the nectar, and then into the honey that bees produce remain stable in honey and propolis for a very long period [4] .…”

“…On the other hand, mineral content in propolis is often utilized to identify the regions of origin as a sign of environmental pollution [10] and to provide trustworthy traceability techniques [5,6,10] . The occurrence of harmful substances in propolis is linked to anthropogenic environmental contamination in the area surrounding the apiaries, which comes from a variety of sources, including air, water, plants and soil.…”

It is possible to classify various propolis samples based on their botanical or geographic origins, since environmental conditions and the harvest season have an impact on the chemical ingredients that make up propolis. In the current research, the determination and geographical classification of propolis samples according to their mineral/metal content are addressed. Acid digestion was employed for mineral/metal recovery and inductively-coupled plasma-optical emission spectrometry was used for accurate quantification. Multivariate techniques, PCA and PLS-DA, were applied for unsupervised and supervised classification for different propolis samples. The measured analytical data can be simply manipulated using chemometric tools, like PCA and PLS-DA. Adequate results were reported by PLS-DA to separate propolis samples that were obtained from industrial and agricultural, but not desert regions. The variations in mineral/metal contents present in propolis were helpful for discrimination purposes. Minerals, like Ca, Na, and K, were the most significant variables for propolis discrimination according to their geographical origins. Based on mineral and metal content, PLS-DA model was effective to classify propolis samples with 92% accuracy as estimated from the confusion matrix.

“…Однак недоліком цукрового сиропу є низький вміст мінеральних речовин, вітамінів, білків та інших біологічно активних поживних речовин, а також високий вміст сахарози, на перетворення якої на більш прості цукри, зокрема глюкозу, бджолами витрачається багато енергії, що, у свою чергу, знижує тривалість їхнього життя (Formicki, 2013).…”

Наведено дослідження щодо визначення вмісту макро-і мікроелементів у меду за підгодівлі бджіл глюкознофруктозним сиропом. Установлено, що на основі отриманих даних дослідження бджолиного меду на вміст металівбіотиків виявлено незначні відхилення щодо їхнього рівня у зразках дослідної групи без виражених вірогідних різниць порівняно з показниками в контрольній групі. Проведений нами аналіз меду показав, що глюкозно-фруктозний сироп, який використовується для підгодівлі бджіл, активізує мінеральний обмін в організмі бджіл та не є забруднювачем меду за токсичними металами.

Raw propolis and bee pollen has been widely used in different areas such as medicine, food and apitherapy because they have biological and medicinal properties. The beneficial effects of both bee products for human health include antibacterial, antiviral, antimicrobial and anti-inflammatory properties. However, hives exposure to heavy metals, due beekeeping practices and environment, is one of the problems facing beekeepers. The presence of cadmium in bee products should be controlled, because of its high toxicity. A lab-made Bismuth Bulk Electrode (BiBE) was developed for cadmium residue determination in Argentinean bee products such as raw propolis and bee pollen employing square wave anodic stripping voltammetry (SWASV) as electrochemical technique. The SWASV parameters were optimised based on a 2 5 factorial design. The method presents a linear range from 2.00 to 100.0 µg L −1 of Cd (II) with a limit of detection (LOD) and a limit of quantitation (LOQ) of 0.78 µg L −1 and 2.61 µg L −1 , respectively. The repeatability was 8.03%, calculated as the relative standard deviation. Recovery experiments were performed using spiked raw propolis and bee pollen samples with standard deviation values from 1.16% to 7.20%. The BiBE is easy and fast to elaborate and the propose method is environmentally friendly and low cost. Then, it can be considered as a good alternative to the quality control of bee products due to its importance in the beekeeping industry.
