Studies on aroma generation in lulo ( Solanum quitoense): enzymatic hydrolysis of glycosides from leaves (original) (raw)

Food Chemistry, 2003

Abstract

Five C13-norisoprenoid glycosides, isolated from lulo (Solanum quitoense) leaves, were subjected to enzymatic hydrolysis with a commercial glucosidase (emulsin) and also with an enzymatic preparation having glycosidase activity, isolated from lulo fruit pulp. The volatile compounds generated after reaction were characterized by capillary GC and capillary GC–MS. Lulo fruit glycosidases were extracted by ammonium sulfate precipitation at pH 6.5 and
