A typical 1 oz serving of breadcrumbs contains 3.8 grams of protein (13.4 g per 100 g), which makes it a moderate source of protein. That covers roughly 8% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 14% of the calories in breadcrumbs come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 111 grains in the database, breadcrumbs ranks 65th by protein per serving, and 554th out of all 796 foods on the site. Set against triticale flour, another grain entry in the database, a serving carries about 0.5 g less protein (triticale flour has 4.3 g per 1/4 cup).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by weight at 28.4 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
