Abstract:
Milk is a complete diet for young and old people due to its high nutritional value. To compensate for the milk demand and supply gap, milk adulteration is increased day by day, which not only decrease its nutritional value but also cause severe health problems. This research enlist the various milk adulterants, their hazardous effects on health, qualitative tests, and quantitative technique (FTIR) to check for adulteration by comparative analysis of raw milk with tetra pack and fresh milk. 120 milk samples were collected. By qualitative parameters, it was estimated that water, table sugar, and starch were present in 100%, 75% and 80% of the milk samples, respectively. Acid, soap and detergents were present in 25%, 40% and 44% of the samples. Skimmed milk powder and glucose were in 26% and 80% of the samples respectively. Using FTIR, characteristic peaks were obtained for raw milk; and for tetra pack milk and fresh milk in the region of 6000-600 cm-1. These characteristic peaks of fresh and tetra-pack milk were compared with those of raw milk peaks. The difference between their spectra implied that milk samples contained adulterants. The increased absorbance in the region of 1710-2850cm-1 showed the presence of carboxyl group and ethylene group, whereas decreased absorbance in the region of 1510-1560cm-1 and 1030-1080cm-1 showed the presence of amide group and carbohydrates respectively. This research suggests that milk sold in West Lahore is very much adulterated, so milk marketing should be governed through laws and regulations to protect consumer health.
