Good Quality Honey?
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 and lose its freshness 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. This results an increase of acidity, which then becomes
an important quality criteria.
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. 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 exposed to in
the distribution channel. 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 or
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 (e.g.
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.
