Number two in a series of ten articles on the different honeys
of America.
As a result of our comprehensive
analytical survey of honeys from the United States, we have complete
data on 504 samples of honey and honeydew from 47 of the 50 States.
These are from 83 floral types and 93 blends of known composition,
as well as other blends characterized by area of production and
time of harvest. By examination of the values found for the individual
samples, we have obtained information on how the many different
kinds of honey compare with each other.
It is well known that various honeys have certain characteristics
- tupelo and sage honey are non-granulating, tulip tree honey
is dark, cotton honey granulates quickly, and so on. In the table
are shown the characteristics of 74 floral types of honey and
4 honeydew types, compared with the average composition of honey,
which was given in the first article in this series. In this
table a plus sign means that the honey is higher than the average
in that particular characteristic. A minus sign means that it
is lower than the average. If no mark is given, the honey is
near the average for that particular characteristic. In the case
of diastase, an "n" means that not enough data were
available to give an estimate. We have not included moisture
content in this table because we do not feel that it is a characteristic
of the floral type of honey, but rather depends on other factors.
No honey type was listed as minus for granulating tendency unless
it was substantially non-granulating in our test. Those marked
plus are particularly prone to granulate. Honeys not marked are
average in granulating tendency under the conditions we used
- in six months storage after heating to liquefy, they would
deposit thin layers (to 1/4") or clumps of crystals in a
jar.
Where a plus is marked for pH it indicates a honey type showing
less active acidity than the average. As an example of reading
the table, alfalfa honey granulates more, is higher in dextrose,
sucrose and lactone/free acid ratio than the average honey. It
is lower than the average honey in its content of higher sugars,
undetermined material, ash, and nitrogen. It is near the average
values in all of the other characteristics.
For the more important and more common honey types, this table
uses the average of many samples. For many of the other more
unusual or locally-produced floral sources, there may have been
only one or two samples analyzed.
This table provides a quick way to compare many of the more important
honey types one with another and to find floral types of honey
with the desired physical and chemical characteristics for any
particular purpose.


Near average in all above characteristics except diastase, which
differs as shown in parentheses: Wild buckwheat (+); clover,
alsike; clover, sweet; clover, white; crotalaria (-); cucumber;
eucalyptus; fireweed; heartsease (n); palmetto, cabbage; pentstemon
(n); purple loosestrife (n); rosinweed (+); vetch; vetch hairy
(-).
1/ "n" means insufficient data were available
to allow valid comparison.
1/ This is one in a series of articles
describing a large-scale study of the composition of honeys from
over the United States. Complete data interpretation and conclusions
will appear in a forthcoming Department of Agriculture publication.
