- Molasses is a by
product of the sugar industry and is the starting raw material for the
production of industrial alcohol, which is used as a source of energy
for automobiles, as well as the production of organic chemicals, such as
aldehydes, acetone, acetic acid, acetic anhydride, isophoron, citric
acid, glycerol, yeast and many other derivatives for pharmaceutical and
plastic industries

There are three popular variety of Citric acid, namely Monohydrate
Citric acid, Anhydrate citric acid and Sodium citrate
-
Citric acid is a weak
organic acid found in citrus fruits. It is a natural preservative and is
also used to add an acidic (sour) taste to foods and soft drinks. In
biochemistry, it is important as an intermediate in the citric acid
cycle and therefore occurs in the metabolism of almost all living
things. It also serves as an environmentally benign cleaning agent and
acts as an antioxidant.
- Citric acid exists in a
variety of fruits and vegetables, but it is most concentrated in lemons
and limes, where it can comprise as much as 8% of the dry weight of the
fruit. At room temperature, citric acid is a white crystalline powder.
It can exist either in an anhydrous (water-free) form, or as a
monohydrate that contains one water molecule for every molecule of
citric acid.
- In this production
technique, which is still the major industrial route to citric acid used
today, cultures of Aspergillus niger are fed on sucrose to produce
citric acid. After the mold is filtered out of the resulting solution,
citric acid is isolated by precipitating it with lime (calcium
hydroxide) to yield calcium citrate salt, from which citric acid is
regenerated by treatment with sulfuric acid.
- Citric acid is used as
a food additive to make foods tart, or to adjust the acidity, or to mix
with bicarbonates to generate carbon dioxide gas. It is also used for
its anti-oxidant properties, to prevent oils from becoming rancid.
Citric acid is highly astringent, and is used as a skin toner.
- Citric acid was
originally extracted from lemons and limes, but it is now produced
commercially by a fermentation process. The mould Aspergillus niger is
used to ferment a carbohydrate source such as Molasses.
- Many of the industrial
applications of Citric acid are based not only upon its acidic
properties, but also upon its powerful sequestering action with various
transient metals, such as iron, copper, nickel, cobalt, chromium and
manganese.
- Hit by high energy and
raw material costs coupled with the ongoing threat of cheaper Chinese
production, US and European citric acid firms have found themselves
increasingly squeezed into an unprofitable market, where increased costs
cannot adequately be recovered through price hikes.
- Citric acid is
one of the most widely used food acids by today's food and beverage
industry, with over 70 per cent of the world's 1.4 million ton market
propelled by this sector. Currently, Europe is left with only three
citric acid factories, the largest of which is Jungbunzlauer's plant in
Pernhofen, Austria.
- Citric acid is one of
the important chemicals used in various industrial processes. It is
estimated that about 500,000 tons of citric acid is produced annually by
fermentation of expensive raw materials like glucose and sucrose. In
developed countries, 65% of citric acid consumption is in food and
beverages and 20% in household detergents with the estimated global
growth rate in demand between a 4 to 5% per year.
- In Asia,
consumption is highest in India, Indonesia, Thailand and the Republic of
Korea. Growth in this region is expected to be 6–7% per year over the
next few years, driven mainly by beverages, which account for 85–90% of
demand.
-
The citric acid market is impacted by
price, which has been driven down by a
combination of strong competition from
Chinese products and an abundance of
global capacity. European producers are
contending with imports from Chinese
producers. While the average prices were
declining, Chinese imports of citric
acid to Western Europe grew
significantly from 2004 to 2007. The
significant increase in imports during
these years led to high European
Commission antidumping duties in 2008,
which helped to increase prices (up
about 35% on average in dollar terms) in
2008 compared with 2007. However, the
antidumping measures have not been as
effective on import volumes as was
expected. After antidumping measures
were applied for all Chinese producers
during 2008, several Chinese producers
were exempted from the antidumping duty
in 2009, as long as they met the minimum
import price (MIP) as defined by the EU
and reviewed quarterly. As a result,
list prices started to drop later in
2009 compared with 2008 levels.
