Using this procedure the reported runs 15–18 performed at 60 ◦C, 350 bar and 2.5 h
provide an averaged y2 = 48.125: the weight of extracted oil was (0.48125)(39.6) = 19.06 g; dividing by the mass of chia seeds (120 g) gives y1–2.5h = 0.158; converting to an extraction time of 0.5 h gives
y1–0.5h = 0.158/3.75 = 0.042 and plotting this value in Fig. 4 it falls between 272 and 408 bar.
