Studying the effect of stabilization systems (ammonia and stabilization buffer) on lipid composition was carried out in order to check if stabilized latex could maintain the profile of lipids as the one obtained from fresh latex. The results indicated that both ammonia and stabilized latex did not affect on lipids content. The clonal difference was found to be more important as fresh latex and stabilized latex had similar lipids content while PB235 had higher lipid content than RRIM600.
In terms of quality both ammonia and stabilization buffer resulted in an increase of free fatty acid content. This indicated the hydrolysis occurred during stabilization periods (5 days). Moreover, lipids from stabilized latex tended to have less antioxidant power as observed from higher %DPPH remaining. Nevertheless, this two stabilization systems could be applied in case that the long storage of latex sample is not required. Indeed, working on extraction of biochemical compounds should be performed with as fresh sample as possible but the stabilization system could be used in case the repetition with the same sample is needed.
