Determination of DOBI & Carotene content in Palm Oil
The deterioration of bleach ability index, or DOBI, is an analytical procedure intended for quality control of crude palm oil. The test attempts to predict the ease of refining of crude palm oil and indicates its oxidative status. Fruit quality is one of the most important factors affecting DOBI values, together with ripeness and storage conditions. Carotene content is also an important quality control parameter for crude palm oil.
The deterioration of bleach ability index (DOBI) is the numerical ratio of the spectrophotometric absorbance at 446 nm to absorbance at 269 nm. The Carotene content is expressed as ppm of beta-carotene and it is calculated with an appropriate mathematical correlation with absorbance at 446 nm.
CDR PalmOilTester shows a very good correlation with MPOB Test Methods p2.6 and p2.9.
