I am trying various regression analyses on data obtained from the study of 6 different cooking oils, control and 4 different material treatments, all samples being sampled at 30 min, 60 min and 90 min heating. I am wondering what a suitable set of categorical variable codes to use for comparing, e.g. material/time or oil/material/time, i.e. 5 X 3 or 6 X 5 X 3 at all levels and interactions, assuming with the latter that "oil" can be included as an independent variable.

I have not opinion about this. I'm not sure I understand the question.
