About these values

The record is raw egg white from fresh eggs. The yolk, which has protein too, is not included. The USDA record is "Egg, white, raw, fresh" (SR Legacy, FDC ID 172183). It gives 10.9 g of protein and 52 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For the white of 1 large egg: 33 × 10.9 ÷ 100 = 3.6 g. Values on this page are rounded to 0.1 g.

A packaged food's own label can differ from the USDA average. When you have the label, its numbers are the ones for that product.
