Moisture content control
Honey absorbs moisture, as a result, honey processing equipment must be completely dry. Honey should also be processed promptly after removal from the hive to prevent it from absorbing moisture from the air, especially in humid climates.
HMF content control (Hydroxymethylfurfural)
This is a break-down product of fructose, formed slowly during honey storage but very quickly when honey is heated. Honey with high HMF content is considered a low-quality product. The amount of HMF present in honey is used as a guide to the age of the honey and/or the amount of heating that has taken place. Some countries set an HMF limit for imported honey. HMF is measured by laboratory tests.
Control of contamination by insects
Honey processing is a sticky operation, and the sugar in honey attracts ants, cockroaches, and flying insects. Careful protection is needed at all stages of processing, including insect screens on doors and windows to prevent contamination by insects.
