Prebiotic activity score and bioactive compounds in longan (Dimocarpus longan Lour.): influence of pectinase in enzyme-assisted extraction [PDF]

open access: yesJournal of Food Science and Technology, 2014
The optimal extraction of bioactive compounds from longan fruit pulp using Pectinex® Ultra SP-L pectinase hydrolysis of the fruit homogenate was evaluated. The highest degree of hydrolysis (DH), as determined by the amount of reducing sugars released from the longan pulp, was obtained at a pectinase concentration of 2.5 % (v/w) (257 polygalacturonase ...
