“…It is known that poppy-seeds contain several lipoxygenase isoenzymes with different pH optima, e.g. in poppy-seeds grown in Czechoslovakia in 1985-88 pH optima were 6.5, 9.5 and 10.5 as measured in phosphate (pH<8.5) and borate (pH>8.5) buffers (MESHEHDANI et al, 1990b).…”

To estimate the quality deterioration caused by lipid peroxidation in stored ground poppy-seed samples, the kinetic behaviour of different biochemical parameters characteristic of lipid peroxidation was studied and compared with flavour deterioration. It was found that the probability of rapid deterioration of samples is low when the change in AC values (the ratio of the values at the time of measurement and at the beginning of investigation) for peroxide values is a linear function of storage time and when lipoxygenase activity is low. When the kinetics is immediately non-linear and high activity of lipoxygenases is detected, the possibility of rapid quality deterioration can be anticipated.
