Influence of storage conditions on quality of rapeseed oil cake for feed

During the past decade, there has been an increased exploitation of organic residues from different sectors of agriculture and industries. Years after the first-generation biodiesel has been introduced, the problem how to utilize large quantities of rapeseed oil cake/meal have arised in terms of their quantity and quality in feed for animals. Due to high free fatty acid content, which is increased with storage period, side-effects, such as those with gastro-intestinal tract can occur. The aim of this study was to determine the change in oil and free fatty acid content in oil cake of four cultivars (Alaska, Eurol, Lirajet, and Silvia) during a one-year storage period, as well as influence of different storage temperatures (4°C and 10°C) on parameters being monitored.
