why to fermenting before palm oil expeller:

Why the palm fruit in the picking 24h for the fermentation?

First in palm oil, the formation of acid is due to palm oil in the lipase or fatty acid catalase in any of the two hydrolysis caused. Under normal circumstances, the free fatty acids of palm oil are generally higher, which is mainly due to the lipase in palm fruits to promote the oil in the hydrolysis, but not broken palm fruit fruit, less free fatty acids.

Second, in the fruit of undamaged palm fruit, the free fatty acid is very low, but once the palm fruit flesh cells are damaged, the fruit lipase activation, in the early free fatty acid will rise sharply;

Third, the late free fatty acids rise and slow down until the lipase activity passivation can be stopped. The amount of free fatty acid in palm oil depends, in fact, on three factors:

1. The maturity of the fruit (too mature fruit is easy to damage);

2. the degree of ear pretreatment (bactericidal) reached;

3. As well as the time between harvest and lipase passivation, the shorter the time the free fatty acid content is lower.
