Mechanical extraction of ferulic acid from banana stem waste
The present of ferulic acid (FA) in plants attract the attention of many researchers, especially in food, pharmaceutical and cosmetic industries. Banana stem waste (BSW) was generated from banana plantation. In this study, FA was extracted from BSW by using sugarcane press machine. There were three...

The first objective was to characterize the compositions of BSW and extracted BSW juice (EBJ). The characterization of BSW was done based on the compositions of moisture, lignin, cellulose and hemicellulose. For the EBJ, it was characterized based on the compositions of total phenolic and glucose. The second objective was to analyze factors affecting FA extraction from BSW.
