Raw Rice
Milled Rice
Unfortunately, despite great progress
in understanding and applying basic
nutritional principles, deficiencies of
essential micronutrients can still be
found in every corner of the world.
And we not only find them where they
might be expected, in low-income
countries where food is scarce and
hunger persists. Dietary imbalances
mean that micronutrient deficiencies
are even found where food is plentiful.
Take rice, for example. It is the major
staple food for millions of individuals,
providing more than a fifth of the world’s
food calories. In Asia people eat about
150 kg of rice annually. But this rice has
been milled, and milling causes most
of the valuable micronutrients in rice
kernels to be lost.
When the food we eat lacks essential
micronutrients it gives rise to a
condition known as hidden hunger.
Food fortification – the addition of
vitamins and minerals to a staple
food – is a safe and efficient way to
improve nutritional status and health
and prevent hidden hunger, without
trying to make people change their
dietary habits. The technology is well
developed and economical: it costs
only a few cents annually to add the
required amounts of micronutrients
to an individual’s diet. Food fortification
is probably the most cost-effective
way to eliminate micronutrient mal-
nutrition and reduce the associated
burden on health-care systems and
increase productivity.
At DSM’s Nutrition ImprovementProgram we have extensiveexperience in fortifying staplefoods, especially rice. As well asoffering scientific and technicalsupport, our global team canassist you with the regulatoryexpertise you need to kick-startyour rice fortification project.

Improving nutritionthrough rice fortification
Fortifying rice is not a straightforward
process. Adding micronutrients is not
the problem – the difficulty is making
them stay where they are needed, even
when the rice is soaked and rinsed
prior to cooking. An important advance
was made with the development of
reconstituted, fortified rice kernels
which could be added to regular rice.
Unfortunately, these kernels looked
slightly different so that consumers
often saw them as impurities, and
removed them.
To overcome such difficulties, DSM
and our process-engineering partner
Buhler have developed a new
reconstituted kernel production
method with encapsulated micro-
nutrients using an innovative hot
extrusion process. The fortified kernels
look, taste and behave exactly like
normal rice, and the nutrients
embedded in the kernels are efficiently
protected from external influences
during washing and cooking. The
process uses low-cost broken rice as
raw material, and the appearance and
texture, as well as the nutrient content
of the kernels, can be adapted to
the specific requirements of target
consumer groups.
The resulting product offers excellent
physical stability, with minimal loss
of added nutrients during storage,
washing and cooking. To guarantee
the right intake of vitamins and minerals
for good health, NutriRice fortified
kernels are mixed with regular rice in
a ratio of 0.5–2%. NutriRice is therefore
a better source of essential micro-
nutrients than rice fortified by any
other method.

Better performance at theDandelion Middle School,Beijing
The children of 600 migrant workers
attend the Dandelion Middle School
in Beijing, some of them as resident
pupils. In 2008, as part of a pilot project,
all pupils at the school were given
NutriRice for a period of eight months.
Their food was also supplemented
with soy sauce enriched with iron
and oil enriched with vitamin A. The
Chinese Center for Disease Control and
Prevention (CDC), which is investigating
the potential for enriched staple foods
to improve the critical nutritional status
of certain disadvantaged population
segments, provided start-up help for
the project.
Proveneffectiveness
Before the trial, all pupils were given
a physical examination. The Chinese
CDC diagnosed general malnutrition:
especially prominent were anemia,
vitamin A deficiency and vitamin
B-complex deficiency. The children
were also found to be severely deficient
in zinc, an important trace element
without which growth is impeded.
The intervention achieved a
marked reduction in vitamin B1
and vitamin B2 deficiency.
Further, we were able to significantly
increase the amount of iron-containing
proteins in the red blood cells. This
manifested itself in the children’s
increased capacity to memorize and
their ability to concentrate. In sports,
During the eight-month trialperiod at the Dandelion MiddleSchool the effects of malnutri-tion were reduced by 50 percent,thus raising the pupils’ generalnutritional status to the averageurban level.
too, teachers noticed a marked impro-
vement. The children’s physical strength
and stamina increased substantially, as
did performance levels in general.
Efficacy trial inBangalore, India
In a poor urban setting in Bangalore,
India, DSM collaborated with the
St. John’s Research Institute to conduct
a trial to study the effects of NutriRice
on school children aged 6-12 years.
After six months the positive impact
of NutriRice was clearly evident.
Specifically, the children’s B-vitamin
status had improved significantly and
there was an improvement in physical
performance, particularly physical
endurance, among the children who
consumed NutriRice.

In recent years, quality assurance,
traceability and sustainability have
gained further importance in the food
and feed industry. Historically, DSM
has adhered to the highest standards
in this area, and is recognized as
an industry leader by customers
and regulatory authorities. Quality
assurance, traceability and sustainability
come at a cost. They are embedded
in operating procedures, facilities,
environmental and microbiological
control, calibration and validation.
Quality is more than systems, human
resources and investment. It is a
commitment and a mindset created
throughout many generations of
industrialization.
With all this in mind, DSM created
Quality for Life™.
