    Profile of honey, bee pollen and bee bread: comparative shotgun sequencing

    Morgil, Hande; Ecem Bayram, Nesrin

    The plant origin of the bee products often influences their value. Here, we investigated for the first time how the content of bee bread, a functional food with high nutritional value, differs in terms of plant and bacterial taxa in comparison with bee pollen and honey samples, using shotgun sequencing analysis. Sequencing of honey, bee pollen, and bee bread samples yielded approximately 32.74 Gbp of data. Out of a total of 268,964 abundant genes, 70,280 genes (26.13%) were assigned to a taxonomic group according to the supermajority rule. These taxonomic groups were annotated as follows: Kingdom (84.99%), phylum (75.94%), class (73.26%), order (67.21%), and family (65.11%). It was determined that honey, bee pollen, and bee bread samples consisted of large plant families Poaceae, Fabaceae and Asteraceae. This indicates that these taxa are also favored by bees for visiting, and are therefore used as food sources. These differences vary according to the environmental flora of the apiary and may be site specific. Based on these results, DNA-based next-generation sequencing techniques can be successfully used to identify the plant sources of bee products. Thus, the botanical and geographical origin of bee product samples can be more accurately, reliably and in detail identified. Furthermore, this technique can be successfully used to monitor the regional flora and food safety.

    Birinci, Ceren; Kara, Yakup; Gıdık, Betül; Kolaylı, Sevgi; Can, Zehra

    To achieve a highly selective and sensitive analysis of phenolic compounds in bee products (honey, bee bread, and propolis), a simultaneous quantification of 25 phenolic compounds was performed using high-performance liquid chromatography coupled with a diode array detector. In the study, various solvents were utilized to enhance the phenolic profile of bee products, including pH 2 and 7 ultra-pure water, diethyl ether, and ethyl acetate. These included non-liquid–liquid extraction, pH 2 with 10 mL of pure water and 20 mL of diethyl ether; pH 2 with 10 mL of pure water and 20 mL of ethyl acetate; pH 2 with 10 mL of pure water, 10 mL of diethyl ether, and 10 mL of ethyl acetate; and pH 7 with 10 mL of pure water, 10 mL of diethyl ether, and 10 mL of ethyl acetate. Additionally, the integration of phenolic compounds identified through the enrichment method was pursued using principal component analysis (PCA). The extraction yields and recovery rates of phenolic compounds can be significantly improved by combining and integrating different extraction techniques. Our results demonstrated that using different solvent combinations significantly improved both the yield and diversity of phenolic compounds extracted from the complex matrices of bee products.

    Bee products are an important source of nutrients and bioactive phytochemicals. This study aimed to determine the chemical composition (proximate composition, general phytochemical composition, sugar, and phenolic profiles) of four different products (honey, bee pollen, bee bread, and propolis), obtained from the same apiary, as well as to assess their biological activity through antioxidant and enzyme inhibition assays (α-amylase, α-glucosidase, lipase, AchE, neuraminidase, angiotensin-converting enzyme, urease, trypsin, tyrosinase, carbonic anhydrase, thioredoxin reductase, adenosine deaminase). Clear differences were observed among the samples in terms of both chemical composition and biological activity. The analysis revealed that bee pollen exhibited the highest carbohydrate content (87.9%), while propolis was identified as the richest source of phenolic compounds (14,858.9 mg/kg) among the analyzed samples. Propolis exhibited the highest biological activity in all applied antioxidant assays (CUPRAC, DPPH•, and ABTS•+) and in most enzyme inhibition assays. Notably, the α-glucosidase inhibition activity of propolis was comparable to that of the reference standard. In addition, honey exhibited remarkable trypsin inhibition, also comparable to the applied standard. These findings highlight the diverse bioactivities of hive products, which could play a key role in promoting health and preventing diseases.

    Organic acids and their derivatives: minor components of bee pollen, bee bread, royal jelly and bee venom

    Çelik, Saffet; Gerçek, Yusuf Can; Özkök, Aslı; Ecem Bayram, Nesrin

    This study aimed to determine the organic acid profiles of bee products such as royal jelly, bee venom, bee pollen and bee bread, as well as to verify the method employed in the study. For this purpose, royal jelly, bee venom, bee pollen and bee bread samples were obtained from different locations, and 55 individual organic acids were determined using the liquid chromatography technique coupled with tandem mass spectrometry (LC–MS/MS), and method verification was carried out. Moreover, principal component and hierarchical cluster analyses were performed to compare the organic acid content of bee products and evaluate the overall variation. According to the results, the order of the total organic acid profiles was determined as bee venom (4141 mg/kg-6260 mg/kg) > bee bread (736–990 mg/kg) > bee pollen (837–1503 mg/kg) > royal jelly (192–1947 mg/kg). Although citric acid (423–41,519 mg/kg) was dominantly detected in samples among the organic acids screened. It is thought that the results obtained will contribute to scientific studies carried out to determine the authenticity of bee products and their standardization.

    Can, Zehra

    In this study, enzyme inhibition of urease and hyaluronidase are clinically important functions were examined by different authenticity bee products. Different floral honey, pollen and propolis samples were analyzed in terms of total phenolic compounds (TPC), total flavonoid contents (TFC), ferric reducing antioxidant capacity (FRAP), cupric reducing antioxidant capacity (CUPRAC), and 2,2-diphenyl-1-picryhydrazyl (DPPH) free radical scavenging activities as antioxidant determinants. For the determination of the phenolic composition of the products, RP-UV-HPLC was used. TPC of the honey, pollen and propolis samples were ranged from 17 to 95 and 770 to 989 mg of gallic acid (GAE)/100g, 135-258 mg of GAE/g, and TFC was 1 to 10 mgQE/100g, and 78 to 99 mgQE/100 g, and 9 to 10 mg of QE/g, respectively. Among the bee products, propolis samples were showed the highest phenolic componds, that contained different quantity of protocatequic acid, catechin, caffeic acid, p-coumaric acid, p-hydroxybenzoic acid, ferulic acid and rutin. The urease inhibition vales (IC50) were changed from 7.02 to 33.25 mg/mL, 5.00 to 8.78 and 0.16 to 1.98 mg/mL in the honey, pollen and propolis samples, respectively. The hyaluronidase inhibition values (IC50) were changed from 0.02 to 0.46 g/mL, 0.02 to 0.26 g/mL and 3.26 to 9.21 μg/mL in the honey, pollen and propolis samples, respectively. Honey, pollen and propolis have a significant inhibition on the enzymes, the inhibition may be due to secondary metabolites of phenolic compounds and the mechanism of the inhibition should be studied in detailed.
