Cow milk

Cow Milk

Cow milk is a nutrient-rich liquid food produced by the mammary glands of cows. It is the primary source of nutrition for young calves before they are able to digest other types of food. Cow milk is a common ingredient in many dairy products such as cheese, butter, yogurt, and ice cream.

Composition

Cow milk is composed of approximately 87% water and 13% solids. The solids include fat, proteins, lactose, and minerals. The primary proteins in cow milk are casein and whey protein. The fat content can vary depending on the breed of cow and its diet.

Nutritional Value

Cow milk is a significant source of essential nutrients, including:

• Calcium
• Vitamin D
• Vitamin B12
• Riboflavin

• Skim milk: Contains less than 0.5% fat.

Processing
