Abstract: |
Because of its high nutritional value and distinctive flavor, natural honey is a premium product with a price tag significantly higher than that of other sweeteners. As a result, honey is often the target of adulteration using low-cost invert sugar syrups. This article looks at two analytical approaches based on isotope fingerprint analysis using isotope ratio mass spectrometry (IRMS) that can be used to detect honey adulteration and safeguard product integrity. Honey is a complex mixture of sugars, proteins and other compounds, produced in nature by honeybees from flower nectar or honeydew. The extent to which its sugars are present is heavily dependent on the floral source and differs significantly between honeys produced in different regions. Climate, processing and storage conditions can also have an effect on the amounts of these sugars.1 Fructose and glucose are the major components of honey, and account for 85–95% of the total sugars present. |
