Area of Science:

• Food Science
• Analytical Chemistry
• Agricultural Science

Background:

• Honey, a natural sweetener, offers significant nutritional and health benefits.
• Variations in honey properties due to geographical origin impact pricing and authenticity.
• Authenticating honey's geographical source is crucial for quality control and consumer trust.

Purpose of the Study:

• To authenticate the geographical origin of honey samples from diverse regions.
• To investigate the relationship between honey's physicochemical properties and its origin.
• To establish a reliable method for honey origin discrimination.

Main Methods:

• Characterization of honey samples from eight countries using physicochemical analyses.
• Spectrophotometric assays for authentication purposes.
• Detailed polyphenolic profiling using Liquid Chromatography-Low Resolution Mass Spectrometry (LC-LRMS).

Main Results:

• Successful discrimination of honey samples based on combined analytical data.
• Classification errors were below 31.9% when considering all analyzed variables.
• Identification of key parameters contributing to geographical authentication.

Conclusions:

• The integrated approach using physicochemical and polyphenolic data is effective for honey geographical authentication.
• This method provides a reliable framework for verifying honey origin and ensuring product quality.
• Further research can refine the analytical protocols for enhanced accuracy.
