Rolled oats
Rolled oats suppliers and sourcing guide
Rolled oats are dehulled oat groats (Avena sativa) that are steamed to stabilize them and then flattened between rollers into flakes. Steaming inactivates the enzymes that would otherwise turn the oat fat rancid. Brands buy them as thick (old-fashioned), regular, quick or baby flakes for granola, bars, baked goods and hot cereal, and as gluten-free oats from dedicated supply chains.

Forms and grades of rolled oats
Suppliers sell different products under the same name. Specify the one you need.
Thick or old-fashioned flakes
Whole groats rolled thick, used where visible flakes and chew matter, such as granola and cookies.
Quick and baby flakes
Groats cut before rolling, or rolled thinner, so they hydrate faster in instant cereals, bars and smoothies.
Gluten-free oats
Oats grown and handled under a purity protocol or mechanically and optically sorted to keep wheat, barley and rye out, then tested for gluten.
Organic
Certified organic oats, offered in the same flake sizes as conventional.
Toasted or kilned
Flakes given extra heat treatment for a roasted flavor and lower moisture in ready-to-eat products.
What to check on the COA
Compare each result with your own specification when the lot arrives.
- Moisture
- Loss on drying, usually specified at a low level for flake stability and crispness.
- Enzyme inactivation
- Lipase or peroxidase test confirming the kilning or steaming step worked; active lipase leads to rancid, bitter flakes.
- Gluten
- Gluten by R5 ELISA for gluten-free grades, reported in ppm against the 20 ppm level used for gluten-free labeling.
- Flake size and foreign material
- Sieve profile for flake size and fines, plus hulls, foreign grains and stones.
- Beta-glucan
- Beta-glucan by an enzymatic method (AOAC 995.16) when the label or a claim depends on the soluble fiber content.
- Mycotoxins and microbiology
- Ochratoxin A and deoxynivalenol by LC-MS/MS or ELISA, plus plate count, yeast and mold and Salmonella.
Storage, lots and expiry
Storage and shelf life
Store in sealed multiwall bags or totes in a cool, dry area with pest control; oats pick up odors and moisture readily. Shelf life comes from the miller's specification, and older lots are usually checked for odor and hexanal or rancid notes before use.
Lots and expiry dates
Flake thickness, fines and moisture vary by mill run and crop year, which changes hydration and texture in bars and baked goods. For gluten-free oats, keep each lot's gluten result on file and keep lots segregated.
Regulatory status
Facts from regulators and standards bodies, each linked to its source.
21 CFR 101.81 describes rolled oats, also known as oatmeal, as produced from 100 percent dehulled, clean oat groats by steaming, cutting, rolling and flaking.
Source: ecfr.gov (opens in a new tab)For the claim in that section, 21 CFR 101.81 lists rolled oats as a source of beta-glucan soluble fiber when they provide at least 4 percent (dry weight basis) beta-glucan and at least 10 percent total dietary fiber.

What should the COA for rolled oats include?
Expect moisture, enzyme inactivation, gluten, flake size and foreign material, beta-glucan and mycotoxins and microbiology, each with its method, specification and result for that lot.
How should rolled oats be stored?
Store in sealed multiwall bags or totes in a cool, dry area with pest control; oats pick up odors and moisture readily. Shelf life comes from the miller's specification, and older lots are usually checked for odor and hexanal or rancid notes before use.
