Study and Analysis of Different Milk Samples of Rajkot Region to Identify Adulterants

Abstract

Abstract Milk is an important sources of all basic nutrients such as protein, fat, carbohydrates, vitamin and minerals. Although milk is readily digested and absorbed food because it contains nutrients which are needed for proper growth and maintenance of body. The present study was carried out keeping in view the recently emerging concern of different adulteration of natural milk with various illegal substances such as Ammonium sulphate, Benzoic acid, Cane sugar, Carbonates, Detergent, Formalin, Glucose, Salicylic acid, Skimmed milk powder and Starch to increases its marketability. This study is organized to be an adulterant based study instead of technique based one, where qualitative detection for most of the common adulterants is enlisted. In recent years, this study was aimed to analyze the hygienic status of milk adulteration sold at various cafes, small hotels and educational institutions in Rajkot. A total of ten samples were collected from different localities in Rajkot, India and tested for detection and extent of different adulteration in milk samples. Out of ten milk samples analyzed for adulteration and milk samples found to be adulterated with benzoic acid, detergent, skimmed milk powder, carbonates, formalin, cane sugar, ammonium sulphate and starch while other adulterants were absent. Following are the significant observations of the study: The extent of adulteration varied significantly with least percentage for Benzoic acid (20%) in Pasteurized milk samples while Ammonium sulphate and Formalin (20%) were present in local milk samples. In addition to this, the extent of adulteration varied significantly with highest percentages for Carbonates, detergents and skimmed milk powder (60%). Formalin and cane sugar (40%) were present in Pasteurized milk samples and local milk sample contain 60% cane sugar, carbonates, detergent, skimmed milk powder and Starch respectively. There are many chemical preservatives like pencillin, streptopenicillin and formaldehyde are added in milk due to increase shelf life of adulterated milk. This addition decreases the nutritive value of milk and these types of adulterants, preservatives and drugs in milk cause very serious health related problems. This paper deals with the analysis of milk samples from Rajkot region in Gujarat and its suburban areas to discover these adulterants.
