Researchers investigated how treating corn stalk with a small amount of acid affects getting sugar from it. They tested different conditions and found that using 0.75% sulfuric acid at 150℃ for 30 minutes gave the best results. This method recovered 85.64% of a sugar called xylose from the corn stalk. After treatment, they got a total of 49.74 grams of sugar from just 100 grams of corn stalk. The temperature of the treatment was the most important factor for getting the most sugar out of the corn stalk, while the amount of acid was the main factor for recovering xylose. The process also made the tough structure of the corn stalk easier to break down.
