But due to heavy population and growing demand supply of milk is tough.
Though there is improvement in Milk yield due to hybridization of cattle, yet the supply is low than the demand. Countries like India which had high amount of milk yielding cattle previously is now low on the number.
This is because farmers are unable to afford the high cost of grazing the cattle and their maintenance. Even the water supply is low and also cattle suffer from sudden diseases which can’t recognized earlier leading to their untimely death. So most farmers are trying to get rid of maintaining cattle for milk production. Even they are also dissatisfied with the sale price of the milk and also support from the governments in terms of insurance to the cattle, proper medical care and non supply of fodder at right time.
Hence the milk supply is going down and demand is raising. So to meet this situation milk suppliers try to enhance milk quantity by mixing with adulterants Further they also use preservatives to see that milk doesn’t get damaged or rotten during the transport.
Milk adulteration is done to
1. Enhance milk quantity for more monetary benefits.
2. To preserve the milk for longer time like during transport etc.
3. Also to mask the lactometers used for quality check.
over all the aim is to gets more monetary benefits. But health of the customer is at risk.
Milk adulteration is done by:
a. Soap water solution. This has high fat value and helps dilute milk so as to be unnoticed.
b. Soda or urea: These are used for dilution due to similarity in colour of solutions to milk.
c. Sugar solution. This helps diluted milk from being detected by lactometer. The lactometer measures lactose density levels. Sugar solution also has lactose. Even the density variation is low due to sugar solution.
d. Just plain water. helps to dilute milk.
e. Wheat flour, starch etc: They add fat and help mask dilution.
f. H2O2; This may be a preservative.But harmful to the body.
Tips to detect milk adulteration:
- By feel and touch of milk or on any surface. Milk drop flows slowly due to viscosity. If it flows fast it means it is diluted much.
- Soda can be detected if there is quick foam or gas on adding lemon juice. Further there chances of fullness in stomach after consuming milk.
- Soap is tough to detect. This can be done by taste. The taste is largely different from normal milk. One may not feel he is drinking milk if soap solution is added.
Health related problems: Milk adulteration mostly affects digestive system largely. t may induce vomiting, acidity or gastric distress.
Tips to have safe milk:
a. Try to find any farmer around your place of living if he supplies milk. The condition is that he must be using rearing cattle for his own needs and willing to give away surplus to other to sustain the fodder cost.
b. Try to purchase milk from reputed companies though expensive.
c. Try to rear own cattle for milk. This is a last option but most reliable option.
