Optimization of oil yield and oil total phenolic content

Oil yield and total polyphenol content in oil for each of the 16 experiments are presented in Table 2. Oil yields ranged from 48.9 to 73%, which is in agreement with the obtained yield for cold expression of other raw materials (Savoire et al., 2013). The maximal oil yield was obtained in trial 14.
