Improvement Acid Pretreatment of Corn Stover for Efficient Pentose Production

Pentoses are five-carbon sugars derived from various raw materials. They are increasingly important because they are used to produce high-value products such as xylitol, a highly sought-after sweetener known for its significant sweetness, which is utilized in various oral care products and foods.This study investigates the extraction of pentoses, specifically xylose from corn stover by employing a central composite design, and response surface methodology. The aim is to identify the optimal pretreatment conditions by evaluating the concentration of H<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>SO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> (% v/v), pretreatment time (min), and Liquid-Solid Ratio (LSR) (mL/g), ultimately achieving xylose yields of up to 31.93 g/L.
