Venture Laboratories has been involved in honey testing since our inception. Historically, honey has been used for food and medicinal purposes, and its current applications continue to grow. Therefore, the integrity, composition and overall quality of honey are important to producers, and those who consume, process, and/or use it.

Acidity is an indication of the degree of honey fermentation, and therefore, honey quality.
Honey diastase activity is a quality factor that is influenced by honey storage and heating; therefore, it is an indicator of honey freshness and overheating.
Analysis of reducing sugars commonly found in honey, in addition to Glucose, Sucrose, Fructose and Galactose content.
Ash content is helpful in depicting floral sources of honey origin.
HMF results from the breakdown of simple sugars (glucose & fructose) at ≤ pH 5. HMF is a naturally-occurring indicator of heat and storage changes in honey, and overall freshness.
Moisture content is the only composition criterion that is part of the Honey Standard that must be fulfilled in the world honey trade. Increased moisture content is an indicator of the ability to undergo fermentation. Honey having high water content is more likely to ferment and therefore decrease honey quality.
Catalase is a very important enzyme that is naturally found in honey. It catalyzes the conversion of damaging hydrogen peroxide to water and elemental oxygen.
Invertase is the enzyme responsible for the conversion of sucrose to fructose and glucose. A freshness invertase standard is used in honey standards of the Beekeeper’s Associations of Germany, Belgium and Spain. Invertase is sensitive to heat and storage damage, and therefore is a freshness indicator.
Proline content varies among types of honey, and is a criterion for ripeness. In some cases, honey proline content is used as an indicator of sugar adulteration.
