Foods Acid Value and the Quality of Fats and Oils
Saponification value in the amount (mg) of alkali required to saponify a definite quantity (gm) of an oil or fat. This value is useful for a comparative study of the fatty acid chain length in oils.... The long chain fatty acids can be of either plant origin (linseed oil, castor oil, soya bean, coconut oil) or animal origin (tallow from cattle and sheep). In general, fats/oils from plant origin are high in unsaturated and low in saturated fatty acids. Fats/oils from animal source are high in saturated and low in unsaturated fatty acids.

Saponification literally means "turning into soap" from the root word, "sapo," which is Latin for soap. The by-products of the saponification reaction, in which the fatty acid and the base combine, are glycerin and soap.... Saponification Table . How much Lye should you use in order to saponify a specific fat or oil? Use this simple saponification table of the most commonly used ingredients to find out.

A rapid method for the quantitative determination of iodine value (IV) and acid value (AV) of red fruit oil (RFO) using FTIR spectroscopy and multivariate calibration of partial least square (PLS) is described. functional capacity evaluation form pdf Low fatty acid fats like coconut oil or palm kernel fat have high saponification numbers of 250, whereas most vegetable oils have a saponification number of approximately 190 It means that, palm oil have the shorter fatty acid chain than corn oil and sunflower oil. For the palm oil and corn oil, the saponification number should higher than sunflower oil because they have shorter fatty acid

Oxidation of food grade oils Editor: Dr Matt Miller The PV test is a good way to measure the amount of primary oxidation products in fresh oils. Oils with significant levels of peroxides may still be odourless if secondary oxidation has not begun. If oxidation is more advanced, the PV may be relatively low but the oil will be obviously rancid. Anisidine value (AV) The secondary stage of
- Saponification value number represents the number of milligrams of potassium hydroxide required to saponify 1g of fat under the conditions specified.    It is a measure of the average molecular weight (or chain length) of all the fatty acids present.
- The saponification value is a measure of the alkali reactive groups in fats and oils and is expressed as the number of milligrams of potassium hydroxide which react with one gram of sample.
- The iodine value is expressed in grams of iodine for the amount of halogens linked with 100g test sample, and is used as degree of unsaturated bond of fats and oils. Iodine value is used to compare the number of C=C contained in natural complex
- Palm oil will give you a hard bar, but also has the properties of conditioning to temper its nature, while coconut and palm kernel, with their lower levels of Oleic acid do not provide much in the way of conditioning (especially coconut). The combination of high levels of Lauric and Myristic acids in coconut oil surely account for its great lathering properties!
