Every 100 kcal of mozzarella (whole milk) brings 7.4 g of protein. On that measure it ranks 21st of the 81 dairy foods in this database and 321st of all 796 foods on the site. Measured by weight instead, its 22.2 g per 100 g ranks 28th in its group.
Protein accounts for roughly 30% of the calories in mozzarella (whole milk), making it moderately protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Weight for weight, mozzarella (whole milk) has 1 g of protein for each gram of fat (22.2 g against 22.1 g per 100 g).
Set against drinkable yogurt, another dairy food entry in the database, a serving carries about 0.7 g more protein (drinkable yogurt has 5.5 g per 1 bottle).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by weight at 28 g, and it covers about 12% of the 50 g FDA Daily Value for protein.
Whole-milk mozzarella has slightly less protein per ounce than part-skim.
