PALM OIL ANALYSIS UV-Vis Spectrophotometers SmartNotes
The Deterioration of Bleachability Index (DOBI) is an analytical quality control of crude palm oil. The DOBI of palm oil indicates of the sample and the ease of processing the palm oil. A higher the fruit is more fresh, ripe and free of contaminates. Bleaching palm oils to refine the oil to an acceptable color as required by manufacturers.
One important parameter is its deterioration of bleachability index (DOBI), which is dependent on the quality of the fruit, as well as its ripeness and storage conditions. The DOBI value indicates how easy it is to refine crude palm oil. A value of less than 1.8 implies poor quality, while values greater than 3 signify high quality.
DOBI and Carotene content test in palm oil | CDR PalmOilTester
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 is a procedure designed to test the quality of crude palm oil and this can be performed using UV Vis spectrophotometry. DOBI is the numeric ratio of the spectrophotometric absorbance at 446nm to that at 269nm: I DOBI =A 446 /A 269, Therefore, the absorbance of crude palm oil samples can be measured at these two fixed wavelengths and a
Relationship between the deterioration of bleachability index (DOBI
For CPO, the impurities level can be coarsely estimated by the deterioration of bleaching index (DOBI). A high DOBI value (e.g. DOBI > 2.99) indicates good quality CPO and ease in processing, while low DOBI value implies low level of carotene and/or high level of oxidised sludge oil, both of which could be detrimental to the processing of CPO.

1. I'm performing Crude Palm Oil DOBI spectrum analysis using uv-1900i UV-VIS spectrophotometer at a range of 269nm and 446nm but it's only giving peak absorbance at 446nm but no reading at 269nm,what could be the problem? Please note that I took 0.4g of CPO and dissolved to 100ml mark volumetric flask using iso-octane, which was also used as

ISO 17932:2011, Palm oil — Determination of the deterioration of
ISO 17932:2011 specifies a method for the determination of the deterioration of bleachability index (DOBI) of crude palm oil and the carotene content of crude or bleached palm oil and their fractions by spectrophotometric examination in the ultraviolet and visible range of the spectrum.
1. Introduction. The fact that palm oil is the most-consumed vegetable oil worldwide explains why its role remains significant (Ndé et al., 2019).Crude palm oil (CPO) is a vegetable oil derived from the pulp of oil palm which consists of solid triacylglyceride or triacylglycerol with lipases, FFAs, pigments, phosphatides, parsia glycerides, coloring agents and carotene (Constant et al., 2017
