Effects of treated and untreated loose oil palm fruitlets with pressurized thermal heating on the oxidative state and carotene content in palm oil

Carotenoids are fat-soluble microconstituents that are usually found in palm oil and have the capability to exert health beneficial effects in humans, including protection against cancer, cardiovascular diseases, and age-related eye diseases. A comparison of the chemical characteristics of the untre...

In addition to higher oil yield, treated loose oil palm fruitlets recorded values for Deterioration rate of Bleachability Index (DOBI) of more than 3 at higher heating temperature and time indicating lower to none oxidation process had occurred due to the decrease in moisture content attained.
