Extraction of microcrystalline cellulose (mcc) from cocoa pod husk via alkaline pretreatment combined with ultrasonication

The aim of this study was to extract microcrystalline cellulose (MCC) from cocoa pod husk (Theobroma cacao L.) via alkaline treatment and ultrasonication. The sieved cocoa pod husk (CPH) was treated with 2% w/v sodium hydroxide (NaOH) for 5h at 80oC in a water bath. Then, it was bleached by aqueous...
