UKF™ — the Unique Kelulut Factor — is a science-backed grading and certification standard that independently verifies the bioactive quality of Malaysian kelulut honey, batch by batch.
Kelulut (stingless bee) honey has remarkable science behind it — but until now, no trusted language to express it. UKF™ gives consumers, healthcare professionals and regulators one simple, verified number that reflects a honey's true bioactive quality.
Modelled on New Zealand's landmark UMF™ system for Manuka honey, UKF is anchored in trehalulose — the rare, low-GI sugar that defines the unique composition of stingless bee honey — supported by freshness, phenolic and antioxidant markers. A honey earns its grade only when it qualifies across every marker, not just one.
The result is a mark you can trust on the shelf, and a standard producers can build a premium around.
Unique Kelulut Factor
Every batch carrying the UKF mark has been independently tested and verified to be:
Verified by trehalulose — the unique biomarker of genuine stingless bee honey. No mislabelling, no dilution.
Low HMF confirms the honey has not been overheated or over-aged — the published evidence that every processing step was done gently.
Total phenolic content and antioxidant capacity measured and graded — proof of real bioactive potency.
Screened for added sugars, syrups and adulterants against the MS 2683:2025 baseline.
Tested by accredited laboratories — not the producer — so the number on the label is one you can trust.
UKF is not a single-compound score. Like UMF's multi-factor test, it verifies quality across four measurable biomarkers — each with scientific precedent in the kelulut literature and Malaysia's MS 2683:2025 standard. The grade is set by the lowest qualifying tier, so a honey must excel across the board.
| Biomarker | What it measures | Test method | Why it matters |
|---|---|---|---|
| Trehalulose | Authenticity + low-GI value | HPLC Sugar Analysis | The signature sugar of stingless bee honey — like Leptosperin for Manuka, it uniquely identifies genuine kelulut, and is a low-GI disaccharide with distinct value. |
| HMF | Freshness & purity | HPLC / Spectrophotometry | Low hydroxymethylfurfural confirms honey has not been overheated, over-aged or adulterated. A vital freshness and quality safeguard. |
| Total Phenolic Content | Antioxidant richness | Folin–Ciocalteu (mg GAE) | Higher TPC means a greater antioxidant load. Extends MS 2683:2025 with a graded quantity threshold. |
| Antioxidant Capacity | Bioactive potency | FRAP / DPPH Assay | A direct measure of radical-scavenging ability that corroborates TPC and confirms biological activity. |
Trehalulose anchors the system as the "Leptosperin equivalent" — the scientifically documented marker found almost exclusively in stingless bee honey.
The UKF number reflects the minimum threshold met across the core markers — trehalulose, phenolic content and antioxidant capacity — with HMF held within freshness limits. The higher the number, the more potent and bioactive the honey.
Thresholds shown are the UKF grading model (trehalulose in g/100g, TPC in mg GAE/100g, DPPH as % inhibition at 0.1 g/ml, FRAP in mg/ml at 20 mg/ml, HMF in mg/kg). Final thresholds are confirmed from accredited pilot-study data.
Only brands whose honey is independently tested and licensed may display a UKF grade. These are the brands currently participating in the standard.

UKF grades are determined by accredited, independent laboratories — never by the producer. That separation is what makes the number on the label trustworthy.
The UKF standard is endorsed by GPUKM — Gabungan Persatuan Usahawan Kelulut Malaysia, the national federation of kelulut entrepreneur associations.
