(Abstract) The present study was carried out keeping in view the recently emerging concern of the adulteration of the natural milk with the synthetic milk. Synthetic milk is prepared by emulsifying vegetable oils with appropriate amount of detergent and urea. Samples of the natural milk with synthetic milk were analyzed for concentration of urea and detergent and their effect is assayed through survey in different population in Uttar Pradesh, India. Children’s had different range of intake of milk. Children of age group 1-5 years consumes about 50-250 mg of milk daily, while of age group 6-18 years of children consumes about 250-1000 ml milk/day and children’s of age group 19-22 consumes milk about 500-1000 ml milk /day. Addition of synthetic milk is on large scale in Meerut district of U.P. and mostly urea in such milk creating huge problem of headache, eyesight and diarrhea in children.

Introduction Liquid milk is an essential nutritional food for infants as well as the aged. Adulteration of natural milk with a chemically synthesized milky liquid (synthetic milk) is a matter of serious concern. The dairy industry employs various checks these tests commonly include determination of fat and total solids by chemical or physical analyses; estimation of sediment by forcing milk through filter pads and noting the residue left; determination of Bacterial count and determination of freezing point etc. (Dean, 1985; Fox, 1992). However, most of these measurements are expensive and time consuming like measurement of conductance (Mebrook & Petty 2003 a and b; Willard et al 2003). Synthetic milk is an excellent imitation of natural milk. Milk fat is mimicked by vegetable oil; the nitrogen component in milk is mimicked by urea; detergents are added to make it frothy. This mixture is so expertly prepared that the specific gravity of the concocted milk is the same as natural buffalo milk. This mixture is then mixed with natural milk in varying proportions. Such milk can be processed into ‘‘value added’’ products which bring in a bigger profit. A recent Indian Council of Medical research (ICMR) report has suggested that such adulterated items have a cancerous effect on the human system and can lead to gradual impairment of the body. Milk is a complex mixture of water, lactose, fat, protein, minerals, and vitamins distributed throughout colloidal and soluble phases. Although the cow is the principal source of milk for human consumption in the United States and many other parts of the world (DePeters 1992). In India most milk is
obtained from the buffalo. The composition of milk from buffalo is water (82.14%), fat (7.44%), protein (4.78%), lactose (4.8%) and ash (0.83%) (Rangappa & Achary, 1973). On average milk has optimum level of urea and other chemicals but due to habit of making huge profit there is on going malpractice of using synthetic milk in the original milk. Therefore there is need to work out regularly in different region of India to expose such malpractices and to check such malpractices adapted ignoring health concerns of people. The effect of urea on animal reproductive system has been carried out by Ropstad etal 1987. They reported that reproduction system and reproductive cycle in animals get badly affected by high concentration of urea. This work is carried out to expose and to increase the awareness among people to decline such malpractices adapted, since it is difficult to detect such harmful...
