Oat Flour
Avena sativaA naturally gluten-free but cross-contamination-prone, high-fiber flour made by milling oats. Gives bread, cakes, and cookies a soft texture.
What Is Oat Flour?
Oat flour is obtained by grinding oat grains (Avena sativa); there are partially bran-containing and whole-bran types. It has a slightly sweet, soft aroma.
The oat plant is naturally gluten-free, but because it shares the same facilities as wheat or barley during sowing, harvesting, and processing, it carries a cross-contamination risk; for this reason, celiac patients are advised to prefer oat flour labeled "certified gluten-free".
Nutritional Value of Oat Flour
100 g of oat flour contains approximately 404 kcal of energy, 14.7 g protein, 9.1 g fat, and 6.5 g fiber; its fat ratio is markedly higher than other grain flours.
What Are the Benefits of Oat Flour?
With its beta-glucan fiber, oat flour, as part of a balanced diet, may contribute to a feeling of fullness; some studies on this are ongoing. Its protein ratio is higher than many other grain flours.
This information is general; oat flour is a food and is not a substitute for medical treatment. It is important for celiac patients to prefer only certified gluten-free oat products.
How Is Oat Flour Selected?
When buying oat flour, attention should be paid to freshness and, for celiac patients, certification information.
- The scent should be lightly sweet and fresh; a sharp/bitter smell indicates the fat has oxidized.
- A "certified gluten-free" label should be sought for celiac patients.
- The package should not have absorbed moisture and should be airtight.
How Is Oat Flour Stored?
Due to its fat ratio, oat flour can go rancid faster than other grain flours; it can be stored for 2–3 months in a cool, dry place, and up to 6 months in the refrigerator.
Using Oat Flour in the Kitchen
Oat flour is used in bread, cake, cookie, pancake, and granola bar recipes. Since its gluten ratio is low, it is usually used mixed with wheat flour.
How Is Oat Flour Made at Home?
Rolled oats can easily be ground into oat flour at home by processing them in a food processor until they turn into a fine powder; this method is a practical alternative to store-bought oat flour.
Which Recipes Use Oat Flour?
Oat flour is used in oatmeal cookies, oat bread, pancakes, granola bars, and some cake recipes; it is usually mixed with wheat flour at certain ratios.
Frequently Asked Questions
Is oat flour gluten-free?
The oat grain is naturally gluten-free but carries a cross-contamination risk with wheat/barley during processing; celiac patients must be sure to prefer certified gluten-free oat flour.
How is oat flour made at home?
Rolled oats can easily be prepared at home by grinding them in a food processor or coffee grinder until they reach a fine powder consistency.
Can oat flour be used alone in bread making?
Since its gluten ratio is low, the dough may not rise enough when used alone; it is usually mixed with wheat flour at certain ratios (for example, 1/4–1/3).
What is the difference between oat flour and rolled oats?
Rolled oats are made by steaming and flattening the oat grain and largely retain the grain's integrity; oat flour is these grains, or raw oats, ground into a fine powder.
Why does oat flour go stale quickly?
Since its fat ratio is higher than other grain flours, it can oxidize and turn rancid over time; for this reason it is recommended to store it in a cool place in amounts that will be consumed within a short time, or in the refrigerator.
