MANUKA? NPA? UMF? MGO? TA?
What are we measuring?
MANUKA: Maori common name for a species commonly referred to in Australia as Teatree and is widely distributed in Australia & NZ
MANUKA HONEY is not unique for bio-activity
NPA: Non Peroxide Antibacterial Activity (NPA) of honey is a scientific scale
UMF: The UMF Unique Manuka Factor is a New Zealand trademark scale
The test used to determine UMF is the NPA test
MGO: Many species of plant nectars and pollens produce honey with Methylglyoxal (MGO). The higher MGO level the higher the NPA:
100% pure raw unheated honey normally has an NPA of at least NPA 10+, or an MGO of at least 250
TA : Total antibacterial effectiveness is the sum of the PA (Peroxide Activity 10+) and NPA
(Non Peroxide Activity)
NPA 15+ = MGO 514 = UMF 25+ = TA 25+
NPA 30+ = MGO 1620 = UMF 30+ = TA 40+
