Manuka Honey: Microbiological Testing (TA & NPA)
Fera ScienceTotal Activity (TA) and Non-Peroxide Activity (NPA) are measures of the ability of a honey to inhibit microbial growth. Phenol equivalence testing through traditional plate bioassay methods is used to accurately assess these levels and allow producers to ensure labelling requirements are met. Our scientists measure the TA of your honey sample as a true to label test. This takes into account both peroxide and non-peroxide ac…
