What percentage of milk composition is water?

  1. 70-80%

  2. 80-90%

  3. 90-95%

  4. 75-85%

The correct answer is: 80-90%

The correct percentage of water composition in milk typically falls within the range of 80-90%. This high water content is a fundamental characteristic of milk and plays a critical role in its overall properties, including texture, flavor, and nutritional aspects. Water serves as a solvent for the other components in milk, such as fats, proteins, lactose, vitamins, and minerals, contributing to the emulsion stability and fluidity of the milk. Understanding the composition of milk is essential for cheese making, as the water content influences curd formation, moisture retention in the final cheese product, and the overall cheese characteristics. While the other ranges provided may seem close to the correct answer, they either underestimate or overestimate the actual percentage of water in milk. This highlights the importance of having accurate knowledge about milk composition when studying cheese production and dairy science.
