Palm oil was fractionated by dry fractionation method to collect the olein and stearin fractions. To form a double bond carbon requires more energy 615 kJmol than to form a single bond 350 kJmol.
The results are normally expressed as the number of grams of iodine absorbed by 100 g of oil or fat considering the conditions of the test. IV measures the number of. For these reasons a guideline value for iodine has not.
On fractionation it can be split into 55 liquid olein and 45 solid stearin.

The more unsaturated the fatty acid the greater the iodine value IV.
General uses of palm oilkernel oil and their fractions in food nutritional and oleochemical products are discussed as well as the potential use of palm oil as an alternative to trans fats. Iodine value can be used to measure the degree of unsaturation of oils and fats. Super olein is more suited to cooler climates.
Iodine value IV is a measure of the unsaturation of oils and fats. IV measures the number of double bonds in the molecular structure of an oil. It contains only 15 percent saturated fatty acids with 85 percent unsaturated fatty acids thus the reason for its high iodine value.
It is expressed in gms the amount of iodine which is taken up by 100 gms of the fat wax or oil. Iodine value can be used to measure the degree of unsaturation of oils and fats. High iodine value oils are prone.
The physical chemical characteristics of fractions were determined by acid value saponification value peroxide value and iodine value parameters that measured by titrimetry method. However iodine is taken up by. It is expressed as the number of grams of iodine absorbed by 100 grams of oil or fat under the test conditions 1.
Ad Just released May 2022 Dont try anything before you read. Iodine value IV is used as a parameter in ride. The iodine value and slip melting point of palm oil palm olein and palm stearin were determined in accordance to MPOB Test Methods p322004 and p422004 respectively.
The higher the iodine value the less stable the oil and the more vulnerable it is to oxidation and free radical production. This parameter is extremely important in the palm oilBreast Cancer has risen from 1 in 23 to 1 in 7-8 since the 1970s. Full PDF Package Download Full PDF Package.
The invention relates to a method for determining an iodine value of palm oil. This work will be of significant interest to scientists researchers medical practitioners pharmacologists ethnobotanists horticulturists food. Potassium K and iodine I are combined in a one-to-one ratio to form potassium iodide.
The iodine value or iodine adsorption value or iodine number or iodine index commonly abbreviated as IV in chemistry is the mass of iodine in grams that is consumed by 100 grams of a chemical substanceIodine numbers are often used to determine the amount of unsaturation in fats oils and waxes. Determination of Iodine Value of Palm Oil by Differential Scanning Calorimetry T. FTIR spectroscopy iodine value palm oil PLS.
The consensus values and their uncertainties were based on the acceptability of statistical agreement of results obtained from collaborating laboratories. The more unsaturated the fatty acid the greater the iodine value IV. A rapid method for the quantitative determination of iodine value IV of palm oil products by FTIR transmission spectroscopy is described.
Based on the TG groups stepwise regression analysis showed that the areas of the disaturated trisaturated and triunsaturated TG peaks could predict the IV with. The iodine value also known as the iodine number is a measure of the degree of unsaturation of fat wax or oil. Dont try anything before you read.
Olein fetches a higher market price and one objective in oil palm breeding is to further increase the proportion of olein to stearin. There are two approaches to achieve this objective. About Palm Oil PALM OIL.
Iodine value IV is used as a parameter in process control as well as a quality parameter in traded palm oil products. 37 Full PDFs related to this paper. The predominance of this FA is the main reason for the low iodine value IV of palm oil and its componentsPotassium Iodine 10 wv Potassium iodide is an inorganic salt.
Therefore it is hypothesized that the IV of an oil can be determined based upon the TG composition of the oil. A short summary of this paper. The higher the iodine value of the palm oil is the lower the saturation degree is the higher the unsaturation degree is and thus the lower the corresponding melting point of the palm oil is and the lower the crystallization temperature corresponding to a cooling crystallizing process is.
This work allowed the identification of interspecific OG hybrids as promising crosses with less lipase activity and higher iodine. Therefore it is hypothesized that the IV of an oil can be determined. Guineensis showed oil in the mesocarp of 547 followed by the OG hybrid 470 and E.

In fatty acids unsaturation occurs mainly as double bonds which are very. Basically there are two major grades of palm olein.
Up to 10 cash back The TG can be classified based on either the TG groups ie triunsaturated monosaturated disaturated or trisaturated or the number of double bonds ie zero one two three or four double bonds. JAOCS 76 6 693-699. A calibration standard was developed by blending palm stearin and superolein in specific.
The standard olein has an iodine value of about 56-59 and cloud point of 10C max. Soybean oil in contrast has an iodine value of 130.
