Defatted almond flour is almond flour that has had most of its natural oil mechanically pressed out before grinding. The result is a lighter, drier powder with significantly more protein and less fat per serving than regular almond flour. It’s increasingly popular among people following low-carb, keto, or high-protein diets who want the benefits of almond flour without all the calories from fat.
How It’s Made
The process starts with whole almonds (blanched or natural) being fed through a mechanical press to extract almond oil. Two main types of presses are used: hydraulic presses for large-scale production and screw presses for smaller batches. No chemical solvents are involved in quality defatted flour. The solid cake left behind after pressing is then ground in a mill and sieved into a fine powder.
The type of press matters quite a bit. Screw presses extract more oil, leaving only about 8.6% fat in the resulting flour. Hydraulic presses are less efficient, leaving around 27% fat. That’s a huge difference, so the fat content on defatted almond flour labels can vary widely depending on how the product was manufactured. When shopping, check the nutrition panel rather than relying on the “defatted” label alone.
Nutrition Compared to Regular Almond Flour
Regular almond flour is rich in fat. A quarter-cup serving contains roughly 15 grams of fat and 7 grams of protein. Defatted versions flip that ratio. Because removing the oil concentrates everything else by weight, you end up with substantially more protein, more fiber, and more minerals per gram of flour.
Protein content in well-pressed defatted almond flour can reach roughly 50% or more by weight, compared to about 21% in standard almond flour. The amino acid profile is balanced and consistent, containing all essential amino acids including leucine, lysine, and tryptophan. It’s particularly rich in glutamic acid and arginine. Magnesium is also concentrated in the defatted version, reaching over 490 mg per 100 grams, which is a meaningful amount given that many adults fall short of their daily magnesium needs.
The calorie count drops considerably too. Fat carries 9 calories per gram compared to 4 for protein, so removing a large portion of the oil can cut total calories by 30% to 40% per serving depending on how thoroughly the flour was defatted.
How It Behaves in Baking
Defatted almond flour does not behave the same as regular almond flour in recipes, and regular almond flour already behaves quite differently from wheat flour. With much of the oil removed, defatted almond flour is drier and more absorbent. It tends to produce a lighter, less dense texture in baked goods, closer to what you might expect from traditional flour.
If you’re substituting it into a recipe designed for regular almond flour, you’ll likely need to increase the liquid ingredients. Extra eggs, milk, or water can compensate for the missing fat. Some bakers also add a small amount of oil or butter back in to keep things moist, which still results in a lower-fat product overall. Start by adding one to two tablespoons of extra liquid per cup of flour and adjust from there.
You cannot do a simple 1:1 swap with wheat flour either. The general guideline for almond flour is to use about half to three-quarters of a cup for every cup of wheat flour, and defatted almond flour follows a similar ratio. Because it lacks gluten, you’ll still need a binding agent (eggs work well) to give structure to breads, muffins, and cakes.
Why People Choose It
The main appeal is the protein-to-calorie ratio. Regular almond flour is nutritious but calorie-dense, which can add up fast in recipes that call for two or three cups. Defatted almond flour lets you keep the nutty flavor, the grain-free benefit, and the low-carb profile while cutting a significant chunk of fat and calories. That makes it especially useful for people tracking macros or trying to increase protein intake without adding a protein powder to every meal.
It’s also naturally gluten-free, making it suitable for people with celiac disease or gluten sensitivity. And because the manufacturing process is purely mechanical, with no solvents or chemical processing aids, the flour retains the same safety profile as whole almonds. The FDA has reviewed partially defatted almond protein flour and found that mineral levels, even at high intake, remain well below tolerable upper limits for both children and adults.
Storage and Shelf Life
Fat is what goes rancid, so defatted almond flour has a practical advantage over regular almond flour when it comes to shelf life. With less oil to oxidize, it stays fresh longer at room temperature. That said, it’s still best stored in an airtight container in a cool, dry place. Refrigerating or freezing it extends the shelf life further, and is worth doing if you bake infrequently. Regular almond flour typically lasts a few months in the pantry before developing off flavors; defatted versions generally hold up longer under the same conditions.
What to Look for When Buying
Labels vary. Some products say “defatted almond flour,” others say “partially defatted almond protein flour,” and some simply market themselves as “high-protein almond flour.” The key numbers to compare are fat and protein per serving. A well-defatted product will have fat in the single digits per serving and protein north of 10 grams. If the fat content looks similar to regular almond flour, the product may have been pressed with a less efficient method and won’t deliver the nutritional shift you’re looking for.
Also check the ingredient list. Quality defatted almond flour contains one ingredient: almonds. Some brands add fillers, sweeteners, or other flours to the blend. Blanched versions (made from almonds with skins removed) produce a milder flavor and lighter color, while natural versions retain a slightly stronger almond taste and more fiber from the skins.
