Production of keto-disaccharides from aldo-disaccharides in subcritical aqueous ethanol

Isomerization of disaccharides (maltose, isomaltose, cellobiose, lactose, melibiose, palatinose, sucrose, and trehalose) was investigated in subcritical aqueous ethanol. A marked increase in the isomerization of aldo-disaccharides to keto-disaccharides was noted and their hydrolytic reactions were suppressed with increasing ethanol concentration. Under any study condition, the maximum yield of keto-disaccharides produced from aldo-disaccharides linked by β-glycosidic bond was higher than that produced from aldo-disaccharides linked by α-glycosidic bond. Palatinose, a keto-disaccharide, mainly underwent decomposition rather than isomerization in subcritical water and subcritical aqueous ethanol. No isomerization was noted for the non-reducing disaccharides trehalose and sucrose. The rate constant of maltose to maltulose isomerization almost doubled by changing solvent from sub-critical water to 80 wt% aqueous ethanol at 220°C. Increased maltose monohydrate concentration in feed decreased the conversion of maltose and the maximum yield of maltulose, but increased the productivity of maltulose. The maximum productivity of maltulose was ca. 41 g/(h kg-solution).

A novel two-step synthesis of α-linked mannobioses based on an acid-assisted reverse hydrolysis reaction

Instead of an enzyme-assisted reverse hydrolysis reaction for the synthesis of manno-oligosaccharides, we propose here a versatile new approach. By Fischer type glycosylation, a d-mannose solution of extremely high concentration (approximately 83% (w/w)) was incubated at 60 °C for 65 h in 0.5 M HCl. After dilution and neutralization, the small amount of formed β-linked oligosaccharides was hydrolyzed by β-mannosidase. The yields of α-d-Manp-(1→2)-d-Manp (7.9%), α-d-Manp-(1→3)-d-Manp (7.9%), and α-d-Manp-(1→6)-d-Manp (29.1%) isolated by an activated carbon column chromatography were almost identical to those of the enzymatic reaction, but the yield of α-d-Manp-(1→3)-d-Manp increased enormously by the present method.

Identification of oligosaccharides formed during stachyose hydrolysis by pectinex ultra SP-L

The commercial enzyme preparation Pectinex Ultra SP-L containing fructosyltransferase activity was used to hydrolyze stachyose. During this reaction, besides the formation of mono-, di-, and trisaccharides (DP 3), the presence of one pentasacch
