CHEMICAL-CHANGES IN THE LIPIDS OF CANOLA AND FLAX SEEDS DURING STORAGE

The changes in acid value (AV), peroxide value (PV), anisidine value ( AnV), tocopherols and fatty acid composition in crushed flax, canola s eeds or commercial poultry feed during a 60-day storage period in room temperature (RT) or cold room (CR) were examined. Storage at RT or CR increased AV, PV and AnV of flax and canola seeds. Regardless of stor age condition, a 50% reduction in the content of tocopherols was obser ved in flax, canola and commercial feed samples at day-30 of storage. The changes in the content of polyunsaturated fatty acids were negligi ble during storage. These results may have implication in the storage and handling of animal feeds containing n-3-polyunsaturated fatty acid -rich oil seeds.
