If oat groats show signs of pest infestation or mold, they should not be consumed as this can pose a risk to food safety. Even in the absence of these signs, if there's uncertainty about the quality or safety of the oats, it's prudent to err on the side of caution and not consume them.
Additional Oat-Based Products
Oat groats, the minimally processed form of oats, are just one option among a variety of oat-based products available on the market. Each product varies in shelf life and preparation method.
Oat Variants
Oat groats come in a few variants, each processed differently to cater to consumer needs. Rolled oats, also known as old-fashioned oats, are made by steaming whole oat groats and rolling them to flatten. They retain most of their nutritional value and can be stored for up to 2 years. Moving to a more processed variant, instant oatmeal is pre-cooked, dried, and often comes in flavored variants. It is designed for quick and easy preparation by simply adding hot water or steaming.
Most oat forms, including steel-cut oats, which are oat groats cut into smaller pieces, offer a hearty texture and a nutty flavor. When stored properly, they also have a long shelf life. Across these oat types, flavoring additives typically don't significantly alter their shelf life.
Commercially Processed Oats
Commercially processed oats, such as those from brands like Quaker, are commonly found in two forms: quick oats and instant oats. Quick oats are oat groats that have been further processed by rolling more thinly and steaming longer, enabling them to cook more rapidly. They can be stored and consumed for months after their "best by" date, typically up to a year.
Instant oats are the most processed form; they are pre-cooked, dried, and often come with flavorings and salts. This convenience comes at the cost of stability, as they tend to have a shorter shelf life than their less processed counterparts, usually around 12 months. Yet, like other oat products, they last well beyond the expiration date if they remain unopened and are stored in a cool, dry place.
Both types of oats, when packaged and stored correctly, can last for a considerable duration, often remaining suitable for consumption well past their indicated "best by" date due to their dry and stable nature.
