Floral classification of honey using liquid chromatography diode array detection China 2013

A high performance liquid chromatography–diode array detection–tandem mass spectrometry (HPLC–DAD–MS/MS) method for determining the floral origin of chaste honey and rape honey samples was firstly presented in this study. Kaempferol, morin and ferulic acid were all used as floral markers to decipher chaste honey from rape honey. Chromatographic fingerprinting at 270 nm and 360 nm could be used […]

Botanical discrimination and classification of honey samples applying GC-MS fingerprinting of headspace volatile compounds

A method for validating discrimination and classification of honey samples performing GC/MS fingerprinting of headspace volatile compounds has been created. A number of varied honey samples from different plants and geographical regions around Greece were tested using orthogonal partial least squares-discriminant analysis (OPLS-DA, soft independent modelling of class analogy (SIMCA) and OPLS-hierarchical cluster analysis (OPLS-HCA).

Storage-induced chemical changes in active components of honey de-regulate its antibacterial activity

In order to explain the reasons for variability in the antibacterial activity of honeys, the causal relationship between both honey floral sources and the activity, and the effect that honey storage has on stability of compounds conferring this activity were analysed. Honey’s fro a wide range of floral sources were screened against Escherichia coli (ATTC […]

Accepted Manuka Speer 2014

  This study analyses pollen-identical pure manuka, kanuka, and a 3 Australian jelly bush honey for non-volatiles by UHPLC-PDA-4 MS/MS and also the volatiles by HS-PME-GC/MS. A chromatographic profile 5 matchup by means of characteristic marker compounds achieved a clear 6 discrimination between manuka, kanuka, and jelly bush honey.   http://www.umf.org.nz/wp-content/myimages/2016/11/Accepted-Manuka-Speer-2014.pdf

DNA ID In Honey 2013

  One of the objectives of work page three within the European Research Project ‘TRACE” was to identify PCR markers for the recognition of plant species affiliated to honey. Within the project “Miel de Corse”, a protected designation of origin (PDO) honey and “Miel de Galicia”, a protected geographical indication (PGI) honey. In addition, both […]

The limitations of the methods of identifying the floral source of honeys

Where the bees were when they produced certain honey can be distinguished by the pollen grains present, thus it is agreeable to use melissopalynology to distinguish the geographical origin of the honey, but there are numerous reasoning behind why it is also less valid in determining the botanical origins of honey. http://www.umf.org.nz/wp-content/myimages/2017/02/Molan-1998-Pollen-in-honey.pdf

Analysis of volatile compounds in New Zealand unifloral honeys by SPME-GC-MS and chemometric based classification of floral source

  Unifloral New Zealand Manuka Honeys have a higher commercial value than the polyfloral honeys; although, identification of floral source be strenuous and time-consuming. In this study, the aim was to establish a timely and semi automated method for identifying these floral sources. http://www.umf.org.nz/wp-content/myimages/2016/11/Revell-Morris-ManleyHarris-2014-GCMS.pdf

Two Medicinal Honeys Have Different Mechanism

Honey is becoming increasingly valued for its antibacterial properties, but concrete knowledge about the mechanism of action remain incomplete. We accessed the bactericidal activity and mechanism of action of RevamilH source (RS) honey and Manuka honey, which are sources of two major honeys awarded a medical grade. The results showed that the RS honey was […]

Corrigendum to First Paper on NPA_MGO correcting curve

Upon review of the date from the methylglyoxal concentrations by the derivatisation method (table 2), it was discovered that there was failure to apply a multiplication of 1.87. This is to take into account dilution caused by addition of derivatisation agent to the honey solution, as well as adjusting for the density of the methoxyl […]

The Use of Australian Honey in Moist Wound Management

Honey has historically been used as a therapeutic agent, and this use dates back over many centuries. In more modern times, honey has seen a growing interest around its natural remedies, which has lead to numerous scientific investigations. Research in New Zealand has tried and proven that Manuka honey possesses unique and special healing properties, […]

Near infrared spectral fingerprinting for confirmation of claimed PDO provenance of honey

Near ultraviolet spectroscopic fingerprints of Corsican honey samples were analysed by an array of chemometric tools in order to authorise their claimed origin. Genuine, unfiltered honeys (n= 373;219 Corsican and 154 non-Corsican) were gathered over the course of two production seasons, the principal goal was to create a particular spectral fingerprint for Corsican honey. After […]

Flavonoids, phenolic acids and abscisic acid in Australian and New Zealand Leptospermum honeys

The quality of honey is based on the botanical and floral origin, as well as the chemical composition (Cherchi, Spaneeda, Tuberoso, and Cabras, 1994) and the price is based on its quality, and is therefore closely tied to origin (Andrade, Ferreres, & Amaral, 1997). Historically, the floral source of a certain honey is established by […]

Where mānuka honey comes from

WHERE DOES MANUKA HONEY COME FROM? You might enjoy high-UMF mānuka honey in your tea, but have you ever wondered where it all comes from? Mānuka – the bush regenerator Mānuka, otherwise known as kahikatoa, is a medium-size native New Zealand tree. It’s one of the first to grow when cleared land is left to [...]

Physico-chemical methods for the characterisation of unifloral honeys: a review

The aim of this work is to review all known physico-chemical methods used to determine the botanical origin of honey. In similar work prior to this, particular attention was paid to the classification power of different classification methods. http://www.umf.org.nz/wp-content/myimages/2017/02/Bogdanov-et-al_2004_Physico-chemical-methods-for-the-characterisation-of-unifloral-honeys-a-review.pdf

How Honey Kills Bacteria

Due to a rise in resistance to antibiotics, honey is becoming increasingly valued for its antibacterial properties. To distinguish all bactericidal factors in high grade honey, a novel approach of successive neutralisation was adopted.   http://www.umf.org.nz/wp-content/myimages/2017/02/How-honey-kills-bacteria.pdf

Authenticity Of Honey and Other Bee Products

  The ability to successfully and reliably authenticate natural products, such as honey, is extremely important. Therefore, existing standards for similar products are a basis for authenticity testing. An important role of the International Honey Commission (IHC) is to continue to develop and improve these tests. The current honey standard of Codex Alimentarius was first […]

Authenticity of honey and other bee products: state of the art

Honey authenticity is determined according collectively to the Codex Alimentarius standard, the EU honey directive, as well as by differing national legislations. For other bee products, there are currently no international standards, only national ones. This review covers chiefly honey authenticity issues, and the other bee products are discussed in less detail. The review contains […]
