Authenticity, origin & quality
Using chemical and DNA marker analysis to authenticate a high-value food, manuka honey
Authors: McDonald et al.
PLAIN-LANGUAGE SUMMARY
The study measured nectar-derived chemicals and pollen-derived Manuka and kānuka DNA across authenticated honeys, nectars, and botanical comparators. Classification modelling selected complementary markers that consistently separated New Zealand monofloral and multifloral Manuka categories from relevant non-Manuka and non-New-Zealand samples.
Reported result
Combining chemical and DNA evidence produced more robust regulatory identification criteria than relying on a single marker.
Study design
multiseason marker evaluation and classification modelling
Authenticity, origin and quality
Tested material
Mānuka, kānuka and comparator honey samples or analytical standards described by the publication.
Limitations
The criteria are tailored to the sampled New Zealand production context and regulatory categories and still depend on representative reference data and validated laboratory methods.
Funding & conflicts
Not yet transcribed from the primary publication.
Applicability guardrail
Regulatory authenticity classification does not establish UMF equivalence, antimicrobial potency, product safety, or therapeutic efficacy.
