What is Total Activity (TA)?
TA stands for Total Activity, and it measures the both the peroxide activity (PA) and non-peroxide activity (NPA) in a honey. A honey's TA rating is a representation of its antimicrobial quality i.e. how good it is at killing bacteria. The higher the TA rating, the higher the antimicrobial strength.
TA vs UMF vs MGO
Most of the total activity in Manuka honey is non-peroxide activity, and the active chemical is methylglyoxal (MGO).
The two main rating systems are:
UMF (Unique Manuka Factor) - A trademark term used to indicate the NPA level of Manuka honey. Common UMF ranges between 5+ to 20+, and it is comparable TA. However, UMF measures only the NPA, whereas TA measures both PA and NPA.
MGO (Methylglyoxal) - Indicates the content of methylglyoxal in Manuka honey (mg/kg). The rating typically ranges from 100+ to 1000+.
See comparison table below:
|Total Activity||Equivalent UMF||Equivalent MGO||Strength Rating|
|TA10+||UMF 10+||MGO 263||Mild|
|TA20+||UMF 20+||MGO 829||Strong|
|TA30+||UMF 30+||MGO 1000+||Very Strong|
