Oxygen absorbers. Little paper packets of iron powder.

  I think a lot of us might even confuse the two. The packets look fairly similar too.

  Yeah don't. Like many metals, finely dispersed iron can self-combust on air. I'd suggest an air-tight packaging filled with CO2, or, if your food is susceptible to acid, N2, if at all feasible. Industry uses additives similar to hydroquinone, mixed directly into, e.g., plastics. Plenty of them are food-safe, but I wouldn't know where to buy them if you aren't a business.

    You leave the iron powder in the packets. No need to disperse it, and certainly not in the air.
