. Iodine value can be used to measure the degree of unsaturation of oils and fats. Basically there are two major grades of palm olein. Pulp and paper industry - Wikipedia 5723 Iodine value.
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. 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. 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.
Oil Palm Bunch. It is expressed in gms the amount of iodine which is taken up by 100 gms of the fat wax or oil. The iodine value also known as the iodine number is a measure of the degree of unsaturation of fat wax or oil.
Palm Oil Fractions. In fatty acids unsaturation occurs mainly as double bonds which are very. IV measures the number of.
These oils are distinguished from other oils by their high levels 416683 of palmitic C160 acid. On fractionation it can be split into 55 liquid olein and 45 solid stearin. To form a double bond carbon requires more energy 615 kJmol than to form a single bond 350 kJmol.
The specifications are given in Malaysian Standard MS8162007Table 3. Olein fetches a higher market price and one objective in oil palm breeding is to further increase the proportion of olein to stearin. Up to 10 cash back Iodine value IV is used as a parameter in process control as well as a quality parameter in traded palm oil products.
About Palm Oil PALM OIL. This work allowed the identification of interspecific OG hybrids as promising crosses with less lipase activity and higher iodine. 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.
Therefore the thermal behavior of an oil could reflect. The iodine values of palm kernel oil were found to be 3674g I 2100g. 4 otsb1041rbd palm oil as plamitic 010 010 50-5 5 33-3 9 3r otsb1042rbd palm olein 010 010 56 min 24.
Otsb1040crude palm oil cpo 5 00025 23-2. Iodine is not taken up by saturated oils waxes or fats because their iodine value is zero. The iodine value of the oil was 55217 g I 2 100 g oil which indicated that the oil was likely to be high in saturated fatty acids as it had an iodine value similar to that of palm oil.
Therefore it is hypothesized that the IV of an oil can be determined based upon the TG composition of the oil. Double bonds react with iodine in alcoholic solution determining a variation in the reagents absorbance. However iodine is taken up by.
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. A calibration standard was developed by blending palm stearin and superolein in specific ratios that covered a range of 279 to 653 IV units. Determination of Iodine Value in Palm Oil.
There are two approaches to achieve this objective. Principle of the test. Iodine value recommended standards are as follows g of iodine100g of oil.
The predominance of this FA is the main reason for the low iodine value IV of palm oil and its componentsSeed oils have found application as food. Thanks to its simplicity the innovative CDR method for the determination of Iodine Value IV in Palm Oil is ideal to be used during every process stage to monitor the quality of oil in real time and during the acceptance of crude oil as well as during trading of finished products. PALM OIL INDUSTRY-RM451b PLANTED AREA 0F 43m hectares production of 158 m tonnes oil.
Iodine value IV is used as a parameter in process control as well as a quality parameter in traded palm oil products. Guineensis showed oil in the mesocarp of 547 followed by the OG hybrid 470 and E. Oleifera 136 and the iodine values were 520 663 and 774 g I2 100 g-1 respectively.
Palm 50-55 corn 103-135 soybean 120-143. The iodine values of palm oil obtained are lower than that of groundnut oil. To form a double bond carbon requires more energy 615 kJmol than to form a single bond 350 kJmol.
Standard olein and super olein iodine value greater than 60. Oil palm olein and palm stearin are the oils obtained from palm pulp. Up to 10 cash back A rapid method for the quantitative determination of iodine value IV of palm oil products by FTIR transmission spectroscopy is described.
Iodine Value 14 - 49. This parameter is extremely important in the palm oil. CDR PalmOilTester Iodine Value test shows a good correlation with AOCS Official Method Cd 1d-92.
Iodine value IV is used as a parameter in process control as well as a quality parameter in traded palm oil products. This parameter is extremely important in the palm oil industry where it is used to follow the. The spectra of these standards was measured in the range between 3050 and.
Palm oil has an iodine value of 53 and is semisolid at room temperature. Palm Oil Engineering Bulletin No8 Oct - Dec 1987 p24 Datasheet. 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. Iodine Value Iodine value is used to measure unsaturation or the average number of double bonds in fats and oils. IV measures the number of double bonds in the molecular structure of an oil.
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. Super olein is more suited to cooler climates. IV measures the number of double bonds in the molecular structure of an oil.
Iodine value can be used to measure the degree of unsaturation of oils and fats. Iv iodine value mp melting point dobi deterioration of bleachibility index ry redyellow sap saponifiable matter tfm total fatty matter ppm permitted antioxidants. The standard olein has an iodine value of about 56-59 and cloud point of 10C max.
It is evidently clear that iodine value of oil determines how the oil is defined. These values are lower than that obtained by Atasie and Akinhanmi 2009 with iodine values of 4124g I 2 100g. For refined and crude palm oil and palm kernel oil.
