摘要：

The kinetic behaviours of two types of lipid systems differing in unsaturation ( sunflower oil and lard) and containing 0.05 % alpha-tocopherol are investigated in the presence of different concentrations of ascorbyl palmitate (AP) at different temperatures (25 and 100-degrees-C). The kinetic parameters (efficiency, strength and activity) of AP in the presence and absence of alpha-tocopherol are quantitatively discussed. It is proved that ascorbyl palmitate is not only a synergist of alpha-tocopherol but also a radical type inhibitor of the lipid autoxidation. It is found that the rise of temperature is associated with an increase in activity of AP in the presence of alpha-tocopherol, this increase being more pronounced with the lipid system of lower oxidizability.
