By increase of the fatty acid chain length from 3 to 10 and 10 to 18 carbons, the reaction efficiency increased from 3.3 to 13.3 and 13.3 to 26.7%, respectively. Hence, for acylation of AOT coated starch nanospheres, the reactivity is increased by using fatty acid acyl donors of longer chain length. In an attempt to avoid vinyl ester activation of the free acids, stearic acid was used in place of... 

Another class of carboxylic acid-derived surfactant is the sodium or calcium salts of fatty acid esters. Commercial examples include metal salts of stearic acid esterified with a dimer of lactic acid (sodium stearoyl lactylate) or maleic anhydride (sodium stearoyl fumarate), which are used as emulsifiers in bread making and in bread preservation due to their properties of preventing starch crystallization and dispersing fats [12, 13]. 

Esterification of methyl glucoside (obtained Ifom starch or glucose and methanol) with methyl esters of stearic or oleic acid leads to the desired products (Scheme 4.7). By...
