Common milk adulterants in developing country Nepal: A mini- review
Milk adulteration is a serious concern in developing country Nepal and is at higher risk due to lack of government policies. Milk is almost a complete food containing essential nutrients required for growth and maintenance of the body. Milk is a high-risk commodity that can be adulterated in numerous ways and turn affects milk quality. The quality and safe milk production are one of the biggest problems faced by developing countries, and Nepal is one of them. The reason behind the milk adulteration is more for economic concerns, but the root cause of adulteration is to increase milk demand during the lean season in developing countries and the existing supply chain. Water being cheap is the most common adulterant added in the milk that decreases the nutrient content of milk. Milk producer also adds the preservatives to increase the shelf life of milk, caustic soda to reduce the milk acidity and materials like urea, starch, sugar and milk powder to increase SNF content. Such milk adulterants can possess serious health hazards to the public leading to fatal diseases. This review shows the common milk adulteration practices in-country Nepal and their impacts on food safety and human health and emphasize potential strategies for control of such adulteration practices.Keywords:Adulteration, Milk quality, food safety, human healthself Adam, A.A.H. 2009.
