Neutralizers like baking soda are added to milk to make it last longer, which might turn harmful in the long run
Do
you ever bother about the quality of milk you consume every day in
various forms? If not, be careful. Six out of eight major brands among
the milk sold in Bengaluru have been proved to be of substandard
quality.
During a BBMP council meeting held on September 30, 2013,
Corporator S Harish submitted an astounding report on the eight milk
brands distributed in the city.
However buyers of Nandini (a product of Karnataka Milk
Federation - KMF) and Thirumala toned milk needn’t worry. Reports gave a
clean chit to Nandini and and Tirumala. Some parameters pf rest of the
brands - Prakruthi, Vamsi, Shiva Shakthi, Arokya, Milky Way and Aamolya
toned milk - did not seem to be falling within the standards recommended
by Food Safety and Standards Authority of India (FSSAI).
Mahalakshmipuram Councillor S Harish says that these brands
come to Bangalore from the outskirts of the city or far off places like
Tamil nadu and Andhra Pradesh.
Helping milk last long by adding chemicals
The samples of milk analysed by Harish and team were
collected from Bangalore market area. Five samples -Nandini toned milk,
Prakruthi, Vamsi, Shiva Shakthi and Arokya toned milk - weighed 500 ml
while three others - Tirumala, Milk Way and Aamolya - weighed 250 ml.
They were tested at National Dairy Research Institute (NDRI) on September 23, 2013.
After processing, that is pasteurisation, milk can survive
maximum two days. Milk should be consumed within 24 hours. Since daries
of most of these brands operate at far-flung places, by the time it
reaches the end user, almost a day is over. To preserve the milk for a
long time, various chemicals are used as preservatives.
Tests done on Vamsi, Milky way, Aamolya, Prakruthi and
Shiva Shakthi show that the acidity and fat level are far below the
standards recommended by FSSAI.
Acidity level can plunge to this level only through
chemicals. These chemicals are used for two reasons: To make the milk
look thick and to preserve it for a longer period.
To thicken the milk, gum powder, starch, sugar etc.are
used, while to help the milk last longer and to ensure it doesn’t curdle
while boiling, they make use of neutralisers such as baking soda,
caustic soda or hydrogen peroxide.
The older the milk, higher will be the acidity. Therefore
to preserve milk for a longer period of time, these companies use
neutralizers.
As per the FSSAI standards, milk should have no
neutralizer. However, the test revealed the presence of neutralizers in
five milk samples.
Same price, less weight
The brands tested were also under-weight, when compared to
Nandini brand. The standard weight and volume of toned milk is
prescribed to be at 518 g for 500 ml. 3% decrease in the weight and 3.2%
decrease in the volume was observed in some of the brands during the
test.

Only long term effect
Gastric problems are one of the common problems caused due
to consumption of adulterated milk. These chemicals harm the tender
inner line of the intestine. This injures the digestive system.
There are no immediate effects of consuming adulterated milk but it takes its own time.
Indian Council of Medical Research reported that long term use of adulterated milk can also cause kidney failure or heart problems. or even death.
Patients suffering from blood pressure should avoid sodium.
Consumption of milk with neutraliser may have an adverse effect on such
patients.
Bangalore-based nutritionist
Sheela Krishnaswamy
believes that cardiac issues from adulteration is unlikely. However
“Milk adulteration can have an effect on the stomach or cause food
poisoning, she says,” she says.
Milk is supposed to be slightly acidic, “if a neutraliser
is added in the form of an alkali, this can cause damage to the tissues.
Sodium can increase the risk of high blood pressure. If baking soda
is used as an adulterant, over a period of time it can reduce the
absorption of calcium,” says Sheela.
Veterinarian G N S Reddy is the founder of the first dairy to produce organic milk involving farmers in the State,
Akshayakalpa.
He believes that adulterations can take place at any point of
production. It may occur at the root level i.e farmers, intermediate
level i.e. milk collection centres or final, processing centers.
He says, “There are no methods at present with these
agencies to control quality of milk at the point of production.”
Sometimes absence of refrigerators to transport milk to distant places
force sellers to add chemicals to milk.
He believes that the samples should also be tested for
bacteria, as high incidence of harmful bacteria like coliforms can be of
great public health importance.
What after the report?
The reports were submitted to Mayor B S Satyanarayana and BBMP Commissioner M. Lakshminarayan.
When contacted, Bommanahalli BBMP Health Officer Dr. Suresh claimed
to have not received any complaints against these brands, and therefore
did not take any action against them.
