Epoxidized soybean oil (ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics . ESBO is a yellowish viscous liquid.
Iodine value helps to classify oils according to the degree of unsaturation into drying oils, having IV > 150 (i.e. linseed, tung), semi-drying oils IV : 125 – 150 ( soybean, sunflower) and non-drying oils with IV < 125 (canola, olive, coconut). The IV ranges of several common oils and fats is provided by the table below.
The FCC has been published since 1966. Before 1960s, although the federal Food and Drug Administration (FDA) had by regulations and informal statements defined in general terms quality requirements for food chemicals generally recognized as safe (), these requirements were not published in the official regulations or designed to be sufficiently specific, therefore their use for general ...

For edible oils, the tolerated limit of unsaponifiable matter is 1.5% (olive, refined soybean), while inferior quality crude or pomace oil could reach 3%. [ 12 ] [ 13 ] Determination of unsaponifiables involves a saponification step of the sample followed by extraction of the unsaponifiable using an organic solvent (i.e. diethyl ether ).
Low-fat soy flour is made by adding some oil back into defatted soy flour. Fat levels range from 4.5% to 9%. [167] High-fat soy flour can also be produced by adding back soybean oil to defatted flour, usually at 15%. [173] Soy lecithin can be added (up to 15%) to soy flour to make lecithinated soy flour. It increases dispersibility and gives it ...
