(A) Headspace-oxygen consumption profile of LA and CLA with or without addition of 200 ppm GTC or 200 ppm BHT at 90°C. Data are expressed means ± SD for n = 5 samples. Means at the same time point with different superscript letters (a-d) differ significantly (p < 0.05) (J Agric Food Chem 2000, 48:3072–3076). (B) Headspace-oxygen depletion by CLA/α-CD microencapsulations. The CLA/α-CD microencapsules were incubated in a shaking incubator (35°C, 250 rpm) for a period 80 h. Two and three asterisks represent that headspace-oxygen depletion is significantly different from that of the control, incubated for 80 h, at p < 0.01 and p < 0.001 levels, respectively, by Tukey's w significant test (J Agri Food Chem 2000, 48:3922–3929).
