Optimization of pectin extraction from cocoa husk using citric acid by Response Surface Methodology (RSM) / Noor Fatin Toha

Pectins are complex carbohydrate molecules found in cell wall and middle lamella of plant. Cocoa husk, a by-product in cocoa processing was investigated as a potential source of pectin. This study examined variables that influence pectin extraction from cocoa husk using citric acid. The variables us...
