Abstract: The present invention relates to a method for quantifying 3,6-anhydro-L-galactose using high-performance liquid chromatography and a differential refractometric index detector, whereby L-AHG and D-galactose, which are saccharification products of agarose or agar, can be independently quantified by controlling the separation conditions of the high-performance liquid chromatography/differential refractive index detector, even though the two materials are difficult to separate due to having similar molecular weights and structures.

Abstract: The present invention relates to a heat-resistant agarase and a monosaccharide production method using same. More particularly, in the present invention, a heat-resistant agarase may be used to produce galactose and 3,6-anhydro-L-galactose at high yield by efficiently breaking down agarose or agar without a chemical pretreatment, a neutralization process, or an agarotriose hydrolase treatment process.
