Every 100 kcal of sunflower seed flour brings 14.8 g of protein. On that measure it ranks 2nd of the 27 seeds in this database and 146th of all 796 foods on the site. Measured by weight instead, its 48.1 g per 100 g ranks 2nd in its group.
About 59% of the calories in sunflower seed flour come from protein, which makes it very protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Weight for weight, sunflower seed flour has 29.9 g of protein for each gram of fat (48.1 g against 1.61 g per 100 g).
Set against roasted pepitas, another seed entry in the database, a serving carries about 0.6 g less protein (roasted pepitas has 8.3 g per 1 oz).
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 quoted here is measured by volume at 16 g, and it covers about 15% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
How much protein is in 100 g of sunflower seed flour?
48.1 g. The 1/4 cup serving used on this page weighs 16 g and so carries 7.7 g.
How much protein do you get per 100 calories of sunflower seed flour?
14.8 g. That figure divides its 48.1 g of protein per 100 g by its 326 kcal per 100 g, so it does not depend on serving size.
Is the protein in sunflower seed flour complete?
No. On its own, the protein in sunflower seed flour is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of sunflower seed flour?
About 15%. One 1/4 cup serving has 7.7 g, and the FDA Daily Value for protein is 50 g.
