Table 4.

Total and identified phenolic composition of four oat hull batches grown under different weather conditions (see Table 1 for description). All identified phenolic compounds represent triplicate measurements based on dry weight in µg g^‐1. The total phenolics composition is given as percentage of batch Swe16.
