Introduction:
Honey has been used for medicinal purposes for thousands of years. In recent years, there has been a renewed interest in the medicinal properties of honey, particularly in Manuka honey. It is important to purchase authentic Australian Manuka honey by looking for the AMHA certification mark and an MGO rating that signifies the honey’s quality and health benefits. Manuka honey is a monofloral honey that is produced by bees that feed on the flowers of the Manuka tree (Leptospermum scoparium), which is native to New Zealand and parts of Australia. Manuka honey is known for its unique properties, including its antibacterial and anti-inflammatory effects, making it a popular choice for wound care and other therapeutic applications. This paper will review the chemical composition, health benefits, and therapeutic applications of Manuka honey.
What is Manuka Honey?
Manuka honey is a distinctive type of monofloral honey produced by bees that pollinate the Manuka bush (Leptospermum scoparium), which is native to New Zealand and parts of Australia. This honey is celebrated for its unique antibacterial properties, primarily due to the presence of methylglyoxal (MGO). MGO is formed in the honey through the natural conversion of dihydroxyacetone (DHA), a compound found in the nectar of Manuka flowers.
The quality and potency of Manuka honey are measured using the Unique Manuka Factor (UMF) rating system. This system assesses the concentration of MGO and DHA, with higher UMF ratings indicating stronger antibacterial properties. This makes Manuka honey not only a delicious natural sweetener but also a powerful therapeutic agent.
Chemical Composition of Manuka Honey:
Manuka honey has a unique chemical composition that distinguishes it from other types of honey. It contains a range of bioactive compounds, including phenolic acids, flavonoids, enzymes, and proteins. The following are some of the key compounds found in Manuka honey:
Unique Manuka Factor (UMF):
UMF is a rating system used to measure the antibacterial activity of Manuka honey. It is based on the concentration of methylglyoxal (MGO) and other compounds in the honey. The higher the UMF rating, the higher the antibacterial activity of the honey. (1)
Methylglyoxal (MGO):
MGO is a natural compound found in high concentrations in Manuka honey. It is responsible for the antibacterial activity of the honey and is believed to be the main factor that contributes to its therapeutic properties. (2)
Leptosperin:
Leptosperin is a phenolic compound that is found exclusively in Manuka honey. It is used as a marker to authenticate the authenticity of Manuka honey. (3)
Dihydroxyacetone (DHA):
DHA is a naturally occurring compound found in the nectar of the Manuka tree. It is converted into MGO during the honey-making process. (4)
