“…Briefly, the high diastase and invertase activities imply that honey is raw honey that does not heat (Sahin et al 2020). Unlike invertase and diastase activities, low glucose oxidase activity indicates high-quality raw honey (Bankar et al 2009, Kamboj et al 2019.…”

The composition and biological value of honey vary depending on its producing flora. The botanical, chemical and biological active properties of honey determine the geographical authenticity of the honey. In this study, geographic fingerprints of thirty Astragalus (Astragalus microcephalus Willd.) honeys from Erzincan region were investigated. The honey consists of Astragalus pollen more than 65% and others were Salix spp., Cistaceae, Trifolium spp., Thymus spp, Rosaceae, Papaveraceae, Onobrychis spp. etc. The characteristic color of the analyzed honeys was bright/light yellow, Hunter color values (L, a, b) were found to be as L: 72-78, a: 7-16 and b: 58-78, respectively. Total polyphenol content of the honeys was 38.20±4.60 mg gallic acid equivalent (GAE)/100 g, it was found to be rich in some phenolics such as chrysin, caffeic acid phenyl ester, myricetin, pinocembrin, luteolin, and gallic acid.

“…Karabournioti and Zervalaki (2001) found that the increased levels of HMF in honeys of several botanical origins kept at various temperatures for 24 h were correlated with the temperatures Shapla et al (2018) reviewed HMF concentrations of honey samples from 29 countries after storage for up to three years at temperatures up to 30°C; there was a clear trend for increasing HMF levels with longer storage times and higher storage temperatures, the highest value being 1,132 mg/kg in a Malaysian honey kept at 30°C for more than 2 years. The importance of time and temperature for the level of HMF was confirmed in a controlled study with coriander honey (Kamboj et al, 2019), but the authors emphasize that other factors such as pH, water content, sugar profile, presence of organic acids and floral source of the honey may also have an effect. The multifactorial reasons for HMF formation may explain the highly variable HMF levels reported in the review by Shapla et al (2018).…”

The European Commission has asked the EFSA to evaluate the risk for animal health related to the presence of hydroxymethylfurfural (HMF) in honey bee feed. HMF is a degradation product of particular sugars and can be present in bee feed. HMF is of low acute toxicity in bees but causes increased mortality upon chronic exposure. A benchmark dose lower limit 10% (BMDL 10 ) of 1.16 μg HMF per bee per day has been calculated from mortalities observed in a 20-day study and established as a Reference Point covering also mortality in larvae, drones and queens for which no or insufficient toxicity data were available. Winter bees have a much longer lifespan than summer bees and HMF shows clear time reinforced toxicity (TRT) characteristics. Therefore, additional Reference Point intervals of 0.21-3.1, 0.091-1.1 and 0.019-0.35 µg HMF/bee per day were calculated based on extrapolation to exposure durations of 50, 90 and 180 days, respectively. A total of 219 analytical data of HMF concentrations in bee feed from EU Member States and 88 from Industry were available. Exposure estimates of worker bees and larvae ranged between 0.1 and 0.48, and between 0.1 and 0.51 μg HMF/per day, respectively. They were well below the BMDL 10 of 1.16 μg HMF/bee per day, and thus, no concern was identified. However, when accounting for TRT, the probability that exposures were below established reference point intervals was assessed to be extremely unlikely to almost certain depending on exposure duration. A concern for bee health was identified when bees are exposed to HMF contaminated bee feed for several months.

“…Eventually, the secondary, tertiary, and quaternary protein structures unfold, leading to denaturation (Lee et al., 2022). On the other hand, it is important to note that the optimum pH for enzymatic activities of the invertase enzyme is pH 6, and for the diastase enzyme, it is pH 4.6 (Kamboj et al., 2019; Shankar et al., 2014). However, most of the studies presented an increasing trend of free acidity during the storage period (Table 1).…”

This systematic review paper aims to discuss the trend in quality assessment properties and constituents of honey at different storage conditions and confer the possible whys and wherefores associated with the significant changes. Initially, a literature search was conducted through Google Scholar, ScienceDirect, PubMed, and Scopus databases. In total, 43 manuscripts published between 2001 and 2023 that met the inclusion and exclusion criteria were chosen for the review. As an outcome of this review, prolonged honey storage could deteriorate sensory, nutritional, and antioxidant properties and promote fermentation, granulation, microbial growth, carcinogenicity, organotoxicity, and nephrotoxicity. This systematic review also recognized that diastase activity, invertase activity, 5‐hydroxymethylfurfural content, proline content, sugar content, amino acids, and vitamins could be used as indicators to distinguish fresh and stored honey based on the significant test (p‐value) in the reported studies. However, all the reported studies used the simplest approach (one‐way ANOVA) to identify the significant differences in the analyzed parameter during the storage period and none of them reported an approach to identify the most influential parameter at different storage conditions. In conclusion, orthogonal partial least squares discriminant analysis (supervised multivariate statistical tool) has to be employed in future studies to find the most influential parameter and could be used to potent chemical markers to distinguish fresh and stored honey because this analysis is incorporated with S‐plot, variable importance of projection, and one‐way ANOVA, which can produce the most accurate and precise results rather solely depending on one‐way ANOVA.
