Paper Title
Production of Bioethanol and Biomaterials from Mangosteen Peelwaste by Popping Pretreatment

Abstract
Mangosteen peel waste (MPW) is lignocellulosic agricultural residues that has the potential to produce bioethanol and bio-materials. This paper presents the multiple potential of bio-sugar, α-mangostin and bioethanol production from mangosteen peel waste. The MPW can produce biosugar (164.7 g/kg MPW) from in-house produced cellulase and pectinase at a 90 % conversion rate. The separate hydrolysis and fermentation (SHF) produce bioethanol (63.2 g/kg MPW) with an ethanol conversion yield of 75 %. In addition, we attempted to enhance α-mangostin production by pretreatment and enzymatic hydrolysis. The extraction of α-mangostin increased by 1.46-fold after a combination of popping pretreatment and enzymatic hydrolysis. These results suggest that popping pretreatment can improve the bio-sugar, α-mangostin and bioethanol production of MPW. Keywords - Mangosteen peel, popping pretreatment, Bio-sugar, Bioethanol
