Is Low-Moisture Part-Skim Mozzarella Cheese Vegan?

The Ingredient Breakdown

As a food scientist, I look at the composition of food to understand its origin and processing. When we analyze the standard ingredients list for Low-Moisture Part-Skim Mozzarella Cheese, the verdict is immediately clear. The primary ingredient is pasteurized part-skim milk. This is the fundamental base of all mozzarella cheese, and it comes from cows. Because it is an animal lactation product, it is strictly excluded from vegan diets.

The 'low-moisture' and 'part-skim' labels refer to the manufacturing process. Manufacturers remove some of the whey (liquid) and fat to create a firmer, drier block that melts well for pizza. However, processing does not change the source. The cheese cultures and enzymes used are typically vegetarian (specifically microbial rennet), but the presence of milk renders the product non-vegan regardless of the enzyme source.

There is a common misconception that 'low-fat' dairy is somehow different in category, but biologically, milk is always an animal product. Even if the fat is skimmed off, the lactose and casein proteins remain, which are the defining components of dairy cheese.

Nutritional Value

From a nutritional standpoint, Low-Moisture Part-Skim Mozzarella is often chosen as a 'better-for-you' option compared to whole milk mozzarella. It generally contains fewer calories and less saturated fat because the fat has been physically removed during production. This makes it a popular choice for those monitoring their caloric intake or heart health.

However, it is important to note that 'lower fat' does not mean 'low calorie' in absolute terms. It still contains a significant amount of protein derived from animal sources. For those asking if it fits specific diet limits, it is compliant with omnivorous and vegetarian diets, but it is high in sodium and contains cholesterol, which plant-based cheeses do not.
