Since the fresh palm fruit contains a high activity of lipid decomposing enzyme, when the palm fruit peel is broken, the enzyme will induce neutral oil in pulp to react, and decompose neutral oil into glycerine and free fatty acids, which will make the acid value in the crude oil higher, and each hour will increase 1 fatty acid value(note, the fatty acid is the main important indicator in the oil).
Palm fruit bunches
To make the fatty acid value within the quality requirement, the palm fruit need to be processed within short time after harvested, so take into the technology requirement and economic effect, when build the palm oil mill plant, it should be near to the palm fruit plantation to shorten the time and distance in transporting the palm fruit, in this way, the palm fruit can be processed in time, and enhance the crude oil quality, Besides, there is a lot of moisture in the fresh palm fruit, and the palm bunches occupies too much space, and if transport in long distance, will not economic.
