Oxidation is important to keep in mind because customers like pale products. This is how to prevent oxidation in your liters:
1: Buy a regulator, wand, and gas line

2: Purchase a tank of nitrogen and assemble your air sealer.
???: Transfer your material into your end use container
4: After transferring your material to a media storage bottle, blow air (At a low setting, like 5-6 psi, you are not trying to blast the material out the jar) into the top of the bottle until the fog spills out from the bottle
5: Cap your bottle. Your material is now sealed with inert gas.
Next time I am out there I can take a video.
