e) Storage and packaging

After deodorization, oil must be considered as an oxidisable consumer product. Quality will inexorably diminish as time goes by, and both passive and active protection may be called for.

Oil must therefore be handled, transported, stored and bottled under nitrogen in stainless steel vessels and through stainless steel pipes.

Packaging for catering or retail may be done in plastic containers (PVC is losing market share to polyester) which may either be made opaque or, according to public preference, at least yellow coloured in order to protect from the prooxidative action of light.
