'Molasses' or 'treacle' is a thick
syrup by-product from the processing of the
sugarcane or
sugar beet into
sugar. (In some parts of the U.S., "molasses" also refers to
sorghum syrup.) The word molasses comes from the
Portuguese word ''melaka'', which is in turn derived from the
Greek ''mellas'' —
honey. The quality of molasses depends on the maturity of the sugar cane or beet, the amount of sugar extracted, and the method of extraction.
Cane molasses
Sulphured molasses is made from young green
sugar cane and is treated with
sulfur dioxide fumes, which act as a preservative, during the sugar extraction process. The sugar cane plant is harvested and stripped of its leaves. Its juice is then extracted from the canes, usually by crushing or mashing. The juice is boiled to concentrate and to promote the crystallization of the sugar. The results of this first boiling and removal of sugar crystal is ''first molasses'', which has the highest sugar content because comparatively little sugar has been extracted from the juice.
''Second molasses'' is created from a second boiling and sugar extraction, and has a slight bitter tinge to its taste.
The third boiling of the sugar syrup gives ''blackstrap molasses''. The majority of sucrose from the original juice has been crystallized but blackstrap molasses is still mostly sugar by calories
[1]; however, unlike refined sugars, it contains significant amounts of
vitamins and
minerals. Blackstrap molasses is a source of
calcium,
magnesium,
potassium and
iron. One tablespoon provides up to 20 percent of the daily value of each of those nutrients.
[2][3] Blackstrap is often sold as a health supplement, as well as being used in the manufacture of
cattle feed, and for other industrial uses.
Sugar beet molasses
Molasses that comes from the
sugar beet is different from cane molasses. Only the syrup left from the final
crystallisation stage is called molasses; intermediate syrups are referred to as ''high green'' and ''low green'' and these are recycled within the crystallisation plant to maximise extraction. Beet molasses is about 50% sugar by dry weight, predominantly
sucrose but also containing significant amounts of
glucose and
fructose. Beet molasses is limited in
biotin (Vitamin H or B
7) for cell growth, hence it may need to be supplemented with a biotin source. The non-sugar content includes many salts such as
calcium,
potassium,
oxalate and
chloride. These are either as a result of concentration from the original plant material or as a result of chemicals used in the processing. As such, it is unpalatable and is mainly used as an additive to animal feed (called "molassed sugar beet feed") or as a fermentation feedstock.
It is possible to extract additional sugar from beet molasses through a process known as molasses desugarisation. This technique exploits industrial scale
chromatography to separate sucrose from non-sugar components. The technique is economically viable in trade protected areas where the price of sugar is supported above the world market price. As such it is practised in the
US[4] and parts of
Europe.
Substitutes
Cane molasses is a common ingredient in
baking, often used in baked goods such as
gingerbread cookies. There are a number of substitutions that can be made for molasses; for a
cup of molasses the following may be used (with varying degrees of success): 1 cup honey, or ¾ cup firmly packed
brown sugar, or 1 cup dark
corn syrup, 1 cup granulated sugar with 1/4 cup water, or 1 cup pure
maple syrup.
Other forms
In the cuisines of the Middle East, molasses is produced from several other materials:
carob[1],
grape[2],
date[3],
pomegranate[4], and
mulberry[5].
Uses
★ Molasses is a
chelating agent. A
rusty object placed for two weeks in a mixture of one part molasses to nine parts water will lose its rust due to the chelating action of the molasses.
[5]
★ The British dessert
treacle tart does not use any treacle but
golden syrup.
★ Molasses is the base material for fermentation into which is then used to treat
rum.
★ Molasses is the key ingredient in
Shoofly pie, a mostly
Pennsylvania Dutch dessert in the Southeastern region of Pennsylvania. The pie also includes large quantities of plain and brown sugar, cinnamon, flour, and eggs.
★ Molasses can be used as
carbon source for
in situ remediation of
chlorinated hydrocarbons. See
biostimulation.
★ Molasses is added to waterpipe tobacco to moisten and sweeten the tobacco. Often fruit flavours are added to the molasses. This is called shisha.
Historical references
★ A famous incident involving molasses was the
Boston Molasses Disaster on
January 15 1919, in which a large molasses storage tank burst and flooded a neighborhood of
Boston, killing 21 and injuring 150. The flood advanced as fast as 35 mph. Ironically, "slow as molasses in January" is a (US English)
adage for someone or something that is very slow. Due to the high viscosity of commonly available molasses at room temperature, the liquid pours quite slowly.
Cultural references
★ Molasses is mentioned in the
Tina Turner song
Nutbush, as the only thing (along with
salt pork) that you get in Nutbush
jail.
★ In the 1941 movie ''
Gone with the Wind'',
Scarlett O'Hara (played by
Vivien Leigh) chides
Prissy (played by
Butterfly McQueen) for being "as slow as molasses in January."
