3. Why milk safety & quality is a
concern?
? ? ?

4.  In India, around 70% of population consume milk.
 Milk is considered as a complete food.
 Primary source of calcium in diet.
 Rich in nutrients so favors growth & multiplication
of diseases causing agents.

6. • 6,432 samples collected.
• Picked from 1,103 towns/cities.
• This survey covered both organised ( retailers &
processors) as well as non- organised(local dairy farms,
milk vendors and milk mandis) sectors.
• Samples were tested for 3 contaminants & 13 common
adulterants.

8. Adulterants
Urea
Detergents
H2O2
Neutralizers
8

9. Aflatoxin M1:
 Highly toxic metabolite produced by fungi (Aspergillus
flavus).
 Found in agricultural crops like maize, peanuts, cotton
seed etc.
9

10. Urea :
• Forms major part of the non- protein nitrogen (NPN).
• It increases the MSNF content .
• Detection :
Equal amount of milk sample & p-
Dimethyl Amino Benzaldehyde(DMAB)
are mixed
Yellow colour confirms the
presence of urea
white colour means no urea is
there
10

11. Neutralizers :
 Like NAOH, Na2CO3 & NaHCO3.
 Added to milk to neutralize the developed acidity in
milk , this increases shelf life during transportation.
 Detection method: Rosalic acid method (pure milk
shows brownish colour otherwise rose red colour will
appear)
11

12. Hydrogen Peroxide:
 Used as preservative.
 Activates Lactoperoxidase enzyme & inhibit microbial
growth.
 Detection:
5 ml of milk sample & 5 drops of p-
Phenylene Diamine are mixed
Adulterated milk
will change to blue
No change in non-
adulterated milk

13. Permissible limit
Contaminants & Adulterants Permissible Limit
Aflatoxin M1 0.005 mg/kg
Antibiotics 5-10 ppb
Pesticides
Urea < 70 mg/100 ml
Detergents 3 g/ litre
Hydrogen Peroxide 300-800 ppm
Neutralizers 3 g/ litre

25.  Milk samples from Telangana, followed by Madhya
Pradesh & Kerala, showed the highest number of cases
of adulteration.
 In terms of safety parameters:
1. Out of 2,607 processed milk samples, 10.4% had
safety issues while another 37.7% missed at least one
quality standard.
2. Out of 3,825 raw milk samples, about 4.8% had
safety issues while another 47% missed at least one
quality parameter.
 In terms of quality:
1. 7% of the total milk samples did not comply with
quality parameters that means most of the milk
sold was fit for human consumption.

27. DART
• Detect Adulteration with Rapid Test
• DART booklet is a compilation of quick tests for
detection of food adulterants at household by the
citizens.
• Induces awareness among the citizens.
