Process Optimisation of Ultrasound-Assisted Extraction of Oligosaccharides from Coconut Husk.

ABSTRACT: A fractional factorial design was used to investigate the ultrasound-assisted extraction (UAE) of oligosaccharides from coconut husk, an agroindustry by-product. The effects of five key influencing parameters (X ₁, incubation temperature; X ₂, extraction duration; X ₃, ultrasonicator power; X ₄, NaOH concentration; X ₅, solid-to-liquid ratio) were studied. Total carbohydrate content (TC), total reducing sugar (TRS), and degree of polymerisation (DP) were the dependent variables. The optimal extraction condition was attained when oligosaccharides with a desired DP of 3.72 were extracted when the coconut husk in a liquid-to-solid ratio of 127 mL/g was treated with 1.05 percent (w/v) of NaOH solution at
