Understanding the science
Manuka honey is special - not just for its rich flavour but also for its unique natural properties. To ensure every jar meets the highest standards, we send our honey for rigorous laboratory testing in New Zealand. Each batch undergoes two key tests: the MPI Manuka Markers (4-in-1 Test) to confirm authenticity and the Manuka 3-in-1 Test to measure potency and freshness. These tests verify its origin by checking for key Manuka markers—chemical compounds and DNA—while also measuring MGO (Methylglyoxal), DHA, HMF, and NPA, which determine the honey’s strength and quality. Every batch is independently tested before packing, so you can be sure you’re getting genuine, high-quality Manuka honey.
MPI Manuka Markers (4-in-1 Test) - The Authenticity Check
This test proves the honey is genuine Manuka by detecting four unique chemical markers and Manuka DNA. These markers ensure the honey comes from the Manuka plant and meets strict New Zealand standards.
🧪 2’-MAP, 2-MBA, 3-PLA, 4-HPLA → Four key markers that confirm Manuka authenticity. Higher levels, especially 2’-MAP and 3-PLA, indicate stronger Manuka characteristics.
📊 Classification → The honey is labeled as Monofloral Manuka (higher purity) or Multifloral Manuka (a mix with other floral sources).
🧬 Manuka DNA → Confirms the honey’s botanical origin.
Manuka 3-in-1 Test – The Potency & Freshness Check
🔥 MGO (Methylglyoxal) → The key compound responsible for antibacterial properties. Higher MGO means stronger benefits, typically 100+ (mild) to 800+ (very strong).
⏳ DHA (Dihydroxyacetone) → Converts into MGO over time. A higher DHA level means the honey may increase in potency as it ages.
🌿 HMF (Hydroxymethylfurfural) → A freshness indicator. Lower HMF (below 40 mg/kg is ideal) means the honey has been well-handled and retains its natural benefits.
🛡️ NPA (Non-Peroxide Activity) → A measure of antibacterial strength. 5+ is good, 10+ is very strong.
These tests ensure every jar of Manuka honey meets strict quality standards, so you can enjoy pure, potent, and certified Manuka honey with confidence. 🔥
