ABSTRACT = {After industrial mango processing, tons of residues such as peels and kernels are discarded as waste. Nevertheless, almost 60% of the mango kernel is due to starch on a dry weight basis. Herein, starch from mango (Manguifera Indica L.) kernel was applied to obtain a starch fatty ester with vinyl laurate, in DMSO, under basic catalysis. FTIR, 1H and 13C NMR confirmed that a starch ester with a degree of modification of 2.6 was produced. TGA showed that the modified starch has higher thermal stability than its precursors and higher than a vinyl laurate/starch physical blend. SEM data showed that granular shape and smooth surface on mango starch changed after chemical modification to a continuous and shapeless morphology. This industrial reject derivative behaved as an efficient alternative environmentally friendly fluid loss controller in oil drilling fluids, even in conditions of high temperatures and high pressures (HTHP) drilling.},
