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™.
