Catalytic hydrolysis of Gelidium amansii for 3,6-anhydro-D-galactose production |
| 초록 |
3,6-anhydro-D-galactose (L-AHG) is a major component of agarose in red algae with important biological functions in apoptosis induction, anti-allergy and anti-inflammation. Generally, L-AHG is produced by enzymatic hydrolysis to avoid 5-hydroxymethylfurfural (5-HMF) formation. Herein, L-AHG was extracted from Gelidium amansii using acid catalysts. Reaction conditions which maximized L-AHG production and minimized 5-HMF formation were determined using a statistical approach: 1.18% v/v catalyst concentration, 100°C and 15 min. Glucose and galactose in G. amansii were also extractable at higher temperatures with the latter being extracted first. Increase in catalyst concentration decreased the L-AHG yield and promoted 5-HMF formation. This study demonstrated an economical route for the production of valuable chemicals from red algae.
