Development and Validation of a Gas Chromatography-Mass Spectrometry Method for Determining Acaricides in Bee Pollen

Molecules, Journal Year: 2023, Volume and Issue: 28(6), P. 2497 - 2497

Published: March 9, 2023

Pesticides can be found in beehives for several reasons, including contamination from surrounding crops or their use by beekeepers, which poses a risk to bee ecosystems and consumers. Therefore, efficient sensitive methods are needed determining pesticide residues products. In this study, new analytical method has been developed validated determine seven acaricides (atrazine, chlorpyrifos, chlorfenvinphos, α-endosulfan, bromopropylate, coumaphos, τ-fluvalinate) pollen using gas chromatography coupled mass spectrometry. After an optimization the best sample treatment was obtained when modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) employing ethyl acetate cyclohexane as extractant mixture, mixture of salts clean-up step. A chromatographic analysis (<21 min) performed Agilent DB-5MS column, it operated under programmed temperature conditions. The fully terms selectivity, limits detection (0.2-3.1 µg kg-1) quantification (0.6-9.7 kg-1), linearity, matrix effect (<20% all cases), trueness (recoveries between 80% 108%), precision. Finally, proposed applied analyze commercial samples, some target pesticides (chlorfenvinphos, were detected.

Honey bees are crucial pollinators that play a vital role in maintaining ecological balance. The colonies of managed honey China increased rapidly the past 20 years. Whether rapid increase bee populations would affect survival wild deserves attention. There four species genus Apis Guangxi, China, including florea, dorsata, mellifera ligustica, and cerana. This study conducted an investigation on biological characteristics measured 40 morphological characteristics. results showed for species, their swarming periods, mating emergence drones, nectar pollen source plants highly overlap. leads to potential competition optimum space, nectar, pollen. comparison traits between samples collected 2012 2023 aspect ratios forewings both florea dorsata have significantly increased. change may be attributed bees’ populations, which has encroached upon living spaces A. dorsata. coefficient variations exhibit high genetic diversity.

Truths and myths about superfoods in the era of the COVID-19 pandemic

Critical Reviews in Food Science and Nutrition, Journal Year: 2022, Volume and Issue: 64(3), P. 585 - 602

Published: Aug. 5, 2022

Nowadays, during the current COVID-19 pandemic, consumers increasingly seek foods that not only fulfill basic need (i.e., satisfying hunger) but also enhance human health and well-being. As a result, more attention has been given to some kinds of foods, termed "superfoods," making big claims about their richness in valuable nutrients bioactive compounds as well capability prevent illness, reinforcing immune system, improve overall health.This review is an attempt uncover truths myths superfoods by giving examples most popular (e.g., berries, pomegranates, watermelon, olive, green tea, several seeds nuts, honey, salmon, camel milk, among many others) are commonly reported having unique nutritional, nutraceutical, functional characteristics.While have become buzzword blog articles social media posts, scientific publications still relatively marginal. The reviewed findings show significant driver for consumption. Food Industry 4.0 innovations revolutionized sectors food technologies, including manufacturing offering new opportunities sensory nutritional quality such foods. Although products considered intensively sought consumers, evidence beneficial effectiveness "superpower" yet be provided. Therefore, research collaboration between researchers, industry, policymakers needed differentiate facts from marketing gimmicks promote nutrition.

Headspace with Gas Chromatography-Mass Spectrometry for the Use of Volatile Organic Compound Profile in Botanical Origin Authentication of Honey

Molecules, Journal Year: 2023, Volume and Issue: 28(11), P. 4297 - 4297

Published: May 24, 2023

The botanical origin of honey determines its composition and hence properties product quality. As a highly valued food worldwide, assurance the authenticity is required to prevent potential fraud. In this work, characterisation Spanish honeys from 11 different origins was carried out by headspace gas chromatography coupled with mass spectrometry (HS-GC-MS). A total 27 volatile compounds were monitored, including aldehydes, alcohols, ketones, carboxylic acids, esters monoterpenes. Samples grouped into five categories origins: rosemary, orange blossom, albaida, thousand flower "others" (the remaining studied, due limitation samples available). Method validation performed based on linearity limits detection quantification, allowing quantification 21 in studied. Furthermore, an orthogonal partial least squares-discriminant analysis (OPLS-DA) chemometric model allowed classification established categories, achieving 100% 91.67% success rate, respectively. application proposed methodology tested analysing 16 unknown floral origin, classifying 4 as 8 belonging other origins.

A Meta‐Omics Approach Using eDNA and eRNA for the Assessment of Biotic Communities Associated With Royal Jelly Produced by the Western Honey Bee (Apis mellifera L.)

Molecular Ecology Resources, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 27, 2025

ABSTRACT Royal jelly (RJ) is a glandular secretion fed to developing honey bee larvae by adult worker bees. It also potential source of disease transmission in and between colonies. We endeavored characterize the microbiome, virome, other biota present RJ via an integrated meta‐omics approach. Using magnetic beads‐based extraction protocol, we identified eDNA eRNA fragments from organisms interest using high‐throughput metagenomics (DNA‐seq), metatranscriptomics (total RNA‐seq), parallel sequencing. This allowed us enhance detection Operational Taxonomic Units (OTUs) undetectable standard ‘omics or amplicon protocols’. this approach, detected OTUs pests pathogens, including Melissococcus plutonius , Paenibacillus Varroa destructor V. jacobsoni Aethina tumida Galleria mellonella Vairimorpha ceranae Apis mellifera filamentous virus, Black queen cell Acute paralysis Sacbrood Deformed wing Israeli acute Kashmir Slow as well multiple beneficial gut bacteria genera Lactobacillus Actinobacteria Gluconobacter . The presence DNA RNA these does not conclusively indicate live RJ, but it suggest some exposure organisms. results comprehensive microbial profile demonstrating that our novel method effective sensitive molecular tool for high‐resolution metagenomic metatranscriptomic profiling, value pathogens concern beekeeping industry.
