In this process (Figure 4), orange peel is fed to grinding unit using a conveyer for size reduction.The chopped peel is
mixed with hexane for 10min at 20∘C with peel and solvent ratio of 1 : 2, where limonene is extracted from the peels
and dissolved in the organic phase of hexane. The peel is then separated from the hexane by vacuum filtration which
separates ca 90% of the hexane. Since the remaining hexane in the peel inhibits the digestion, it should be separated and
