Extraction and consecutive purification of anthocyanins from grape pomace using ionic liquid solutions
ÁS Lima, CMF Soares, R Paltram, H Halbwirth… - Fluid Phase Equilibria, 2017 - Elsevier
The global wine industry generates approximately 8.5 million tons of waste annually, which
contains several biomolecules of high value. The present study focuses on the extraction of
anthocyanins from grape pomace via solid/liquid extraction with aqueous solutions of the
ionic liquid 1-ethyl-3-methylimidzaolium acetate [(C 2 mim] OAc) and sequential purification
in aqueous two-phase systems (ATPS) with additional salts. The optimum conditions for
solid/liquid extraction were obtained using response surface methodology and yielded up to …
