Evaluation of Adulterants in Raw Cow Milk from Selale and around Addis Ababa City, Ethiopia

Abstract

Addition of milk adulterants is a serious health problem and can negatively affect the nutritional quality of milk and milk products. In this study milk samples were collected from Selale, Debre Zeit and Sebeta areas and analyzed for formalin, starch, urea, salt and water contents.  Out of 180 analyzed milk samples, 42.22% were adulterated with starch, salt and water. However, formalin and urea were not detected in any of the milk samples.  Percentage of adulterated milk samples collected from Selale, Debre Zeit and Sebeta were 51.66%, 48.33% and 26.66% respectively. Debre Zeit had maximum percentage of water (41.66%) and starch (6.66%) followed by Selale water (38.33%) and starch (5%). While Sebeta had the lowest percentage of contaminated milk samples with starch (3.3%) and water (21.66%). Therefore, there is a need to set control mechanisms and aware producer, milk collectors, dairy processer and consumer on impacts of adulteration.
