Edited by Aimie Carlson || By Harlon Moss || Published on February 23, 2024
Pasteurized Milk is milk heat-treated to kill bacteria and extend shelf life. Unpasteurized Milk is milk in its raw form, without undergoing heat treatment.
Key Differences
Pasteurized Milk is heated to a specific temperature to kill harmful bacteria. Unpasteurized Milk, also known as raw milk, retains its natural bacteria as it hasn't been heat-treated.
Pasteurized Milk has a longer shelf life due to the elimination of microbes. Unpasteurized Milk has a shorter shelf life and can spoil more quickly.
Pasteurized Milk is considered safer for consumption, especially for vulnerable populations. Unpasteurized Milk may contain pathogens that can cause illness.
Pasteurized Milk often undergoes homogenization, a process that further alters it. Unpasteurized Milk maintains its natural fat composition and layers.
Pasteurized Milk is widely available and recommended for general consumption. Unpasteurized Milk is regulated or restricted in many regions due to health concerns.
