ngth and the amount of heating which has taken place. HMF's occurrence and accumulation in honey is variable depending on honey type. High levels of HMF may indicate excessive heating during the extraction process. Honey that is traded in a bulk form is usually required to be below 10 or 15mg/kg to enable further processing and then give some shelf life before a level of 40 mg/kg is reached. It is not uncommon for honey sold in hot climates to be well over 100 mg/kg in HMF. This is mostly due to the ambient temperatures (over 35°C) that honey is ex What is considered as good quality honey?

Even after deciding that a certain floral variety of honey would be your most favourite type of honey, many of us are often still left with the question of “How do I choose the same floral variety of honey amongst all the countless brands of honey from all over the world, with a big range of prices in the market place?"

When I am navigating through the maze of all the different honey in the shops, I look out for certain specific information to ensure that the honey I buy is value for money. Good quality honey, that is, honey of value can be judged by five key factors, namely:

1. Water content

Good quality honey essentially has low water content. Honey is likely to ferment if the water content of honey is greater than 19%. The reason is that all unpasteurized honey contains wild yeasts. Due to the high sugar concentration, these yeasts will pose little risk in low moisture honey because osmosis will draw sufficient water from the yeast to force them into dormancy. In honey that has a higher proportion of water, the yeast may survive and cause fermentation to begin in storage.

Honey is very hygroscopic, which means that it easily absorbs moisture from the air. Thus, in areas with a very high humidity it can be difficult to produce good quality honey of sufficiently low water content, which can be measured using a gadget called refractometer. Raw honey's moisture content can be as low as 14%, and is usually deemed as more valuable and hence is relatively more costly. Honey containing up to 20% water is not recommended for mead-making. One simple way of judging the relative quantity of water in honey involves taking two same-size, same-temperature, well-sealed jars of honey from different sources. Turn the two jars upside-down and watch the bubbles rise. Bubbles in the honey with more water content will rise faster.

2. HMF(Hydroxymethylfurfural)

HMF is a break-down product of fructose (one of the main sugars in honey) formed slowly during storage and very quickly when honey is heated. The amount of HMF present in honey is therefore used as a guide to storage guide to storage length and the amount of heating which has taken place. HMF's occurrence and accumulation in honey is variable depending on honey type. High levels of HMF may indicate excessive heating during the extraction process. Honey that is traded in a bulk form is usually required to be below 10 or 15mg/kg to enable further processing and then give some shelf life before a level of 40 mg/kg is reached.

Some countries set an HMF limit for imported honey. You may also want to note the colour of the honey as it can sometimes be an indicator of quality because honey becomes darker during storage and heating.

3. Inverted sugars

High levels of HMF (greater than 100 mg/kg) can also be an indicator of adulteration with inverted sugars . Cane sugar (sucrose) is "inverted" by heating with a food acid, and this process creates HMF. Many food items sweetened with high fructose corn syrups, e.g. carbonated soft drinks, can have levels of HMF up to 1,000 mg/kg

4. Pollen Content

Good quality honey is expected to be visually free of defect -- clean and clear. Some honeys have a very high pollen content which makes them appear cloudy and this is considered to be poor quality. The presence of any other contaminations (eg particles of wax, bees, splinters of wood, dust) make the honey deemed as of very low value and unattractive for anyone to consumer.

5. Colour

Honey is color graded into light, amber, and dark categories which do not really have any bearing on quality. Some of the most distinctively and strongly flavored honey varieties, such as basswood, are very light, while very mild and pleasant honeys such as tulip poplar can be quite dark. Honey color is measured on the Pfund Scale in millimeters. While it is not an indicator of honey quality and there are exceptions to the rule, generally speaking, the darker color the honey, the higher its mineral contents, the pH readings, and the aroma/flavor levels. Minerals such as potassium, chlorine, sulfur, iron, manganese, magnesium, and sodium have been found to be much higher in darker honeys
