“…Meanwhile, we examined the relation of the partial derivative of the absorption coefficient spectra (in other words, the slope of the absorption coefficient spectra) and invert syrup percentage composition in different wavebands using SLR according to Eqn (7). At the same time, the evaluation model was set up by utilizing the statistical SLR method between the adulterant percentage content and the integrated absorption coefficient wileyonlinelibrary.com/jsfa spectra from 0.5 THz to the different frequencies (in other words, the area of the absorption coefficient spectra) using Eqn (8).…”

BACKGROUND Invert syrup is a common adulterant in honey falsification, thus generating risk for consumers. Most of the methods developed are tedious and time‐consuming for manufactures and consumers. However, terahertz spectroscopy provides analytical information in a simple, rapid, and environmentally friendly manner. Subsequently, 3 kinds of terahertz spectroscopic characteristics data, the absorption coefficient, the slope of the absorption coefficient spectra, and the area of the absorption coefficient spectra, were employed for determination of acacia honey adulterated with invert syrup. RESULTS Single linear regression (SLR) models with different terahertz spectroscopic features were adopted to predict the syrup adulterant proportion in acacia honey. The best SLR model used the area of the absorption coefficient, displaying an adjusted correlation coefficient of 0.985 and a root‐mean‐square error of 3.201. Meanwhile, multiple linear regression (MLR) models using a successive projections algorithm for variables selection were implemented. The MLR model considered the integral area of the absorption coefficient spectra, as the inputs yielded the best result with less variables selected, higher Rc2 and Rp2, lower root‐mean‐square error of calibration and prediction, as well as higher residual predictive deviation. CONCLUSIONS The results indicate terahertz spectroscopy combined with the integral area of the absorption coefficient spectra is reliable enough for invert syrup proportion quantification in acacia honey and is also a rapid and nondestructive determination method for other honey adulterants. © 2019 Society of Chemical Industry

Honeybees (Apis mellifera) crucially pollinate agricultural crops and endemic species, in addition to producing various apiculture products. The most economically relevant and abundant beehive product is honey, a sweet substance made from the secretions of melliferous plants. Honey is a natural food rich in nutrients, including certain bioactive compounds inherited from floral nectar and pollen. Among the most dangerous diseases for bees is American foulbrood. Spores of the causative microorganism, Paenibacillus larvae, can contaminate larvae food or the operculum wax in which larval stages of honeybees are kept. Infection is further promoted by common apiculture practices, such as reusing inert material contaminated with spores, even after months of storage. American foulbrood is untreatable, and management implicates completely incinerating the infected hive and all material that could have come into contact with pathogenic spores. The purpose of such drastic measures is to decrease propagation risk for other beehives. While evidence indicates that antibiotics could effectively control and combat this disease; antibiotic use is prohibited in most honey-producing countries due to increased risks to microbial resistance. Antibiotic residues in honey can affect consumer health, since the natural biological attributes of honey can be altered.

“…Honey is widely consumed in the world and has been considered a healthy foodstuff due to its high nutritional value. In recent years, the occurrence of some antibiotic residues in honey products have been noticed, presenting challenges to conventional picture of honey as a “natural” food . Quinolones (QNs) are one of the most frequently used antibiotics in apiculture to protect bees against a variety of brood diseases .…”

This study presents a simple and green dispersive micro-solid phase extraction method for preconcentration of acidic quinolones from honey prior to high performance liquid chromatography determination. A two-dimensional nanostructured zinc-aluminum layered double hydroxide was synthesized and used as the sorbent for dispersive micro-solid phase extraction. Its different characteristics from conventional sorbents is that it is dissolvable in acidic solution (pH < 4). After the extraction, the analyte elution step was omitted and thus the use of organic solvents was avoided. The key parameters influencing the extraction efficiency such as the amount of sorbent, pH of sample solution, vortex time, type and volume of acidic solution were investigated and optimized. The method exhibited low limits of detection (3.0−5.0 ng/g), good linearity (10−2000 ng/g) with coefficients of determinations higher than 0.9991, acceptable precision (RSD<9.1%) and accuracy (RE<5.8%). The proposed method is fast, efficient, eco-friendly, and suitable for the determination of acidic quinolones in honey samples.
