Determination of DOBI Carotene content in Palm Oil The deterioration of bleachability 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. Analyzers PalmOilTester designed to measure acidity ( FFA ) Iodine Value ( IV ) DOBI carotene content Peroxide Value ( PV ) Anisidine Value ( AnV ) in palm oil Method Test type End point Colorimetric reaction at 446 nm - 269 nm Testing time one test 6 minute Are possible test sessions with several samples up to a maximum of 14. The system is supplied pre-calibrated and ready for use. It is also possible to standardize the system using samples with a known value. Calibration Curve Correlation Data PalmOilTester shows a very good correlation with MPOB Test Methods p2.6 and p2.9. Principle of the test The deterioration of bleachability 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. Composition of the Kit and Reagents Code 300195 suitable for 100 tests contains - R1 4 Bottles containing 25 mL of reagent ( mixture of alcohols ). - 100 test cuvettes with caps.
