Title

EFFECT OF HOT WATER AND DILUTE ACID PRETREATMENT ON THE CHEMICAL PROPERTIES OF LIQUORICE ROOT

Pages

  129-140

Abstract

 In this study, previously extracted liquorice root was prehydrolyzed and the resulting chemical compositions (extractives, lignin content, holocellulose percent), the hydrolysis process yield and weight loss were measured. PRE-HYDROLYSIS process was done by HOT WATER, followed by 0.5 percent sulfuric acid and also alone sulfuric acid with different concentrations (0.5, 1, 1.5 and 2 percent). The samples were pre-hydrolyzed in HOT WATER at 150oC and 30, 60 and 90 minutes as well as in the mixture of HOT WATER and 0.5 % sulfuric acid at 150oC and 30 minutes and also in pure sulfuric acid, at 130oC and at 60 minutes. The results showed that the pre-hydrolyzed treatment with HOT WATER in 60 minutes was the best treatment in respect of weight loss, lignin content and holocellulose percent. Also, in the case of pre-treatment with sulfuric acid, 2% level of acid was a good option in terms of maximum holocellulose percent and minimum lignin content, so it can be suggested to produce higher value-added products such as bioethanol from LICORICE ROOT.
