[0088] Embodiments 1-7 and comparative examples 1-12: hydrolysis reaction

[0089] Using the catalyzer and substrate recorded in Table 1, mix and pulverize raw material 0.374g (in C 6 h 10 o 5 The unit is 2.00 mmol) and 40 mL of water, 0.324 g of the unground substrate, 0.050 g of the catalyst, and 40 mL of water were added to a high-pressure reactor (inner volume 100 mL, autoclave manufactured by Oem Labotec Co., Ltd., manufactured by Hasteroy C22), While stirring at 600 rpm, it was heated from room temperature to the reaction temperature described in Table 1 at 10 to 30°C / min (average temperature increase rate: 11.3°C / min). When the highest reaction temperature is reached, keep the temperature for the time recorded in Table 1, then stop heating, and air-cool the reactor at 10-30°C / min (average cooling rate 16.7°C / min). After cooling, the reaction solution is centrifuged The separation device separates into liquid and solid, and the supernatant sample is analyzed. In addi...

Abstract

The present invention provides a method for manufacturing cellooligosaccharide comprising oligomers having a degree of polymerization of 3 to 6, which is characterized by causing plant biomass, a carbon catalyst and water to be co-present, and performing a heated hydrolysis reaction under conditions such that, in a graph representing the relationship between the reaction temperature (vertical axis) and the reaction time (horizontal axis) the product of temperature and time in the 170 to 230 DEG C range is 80 to 365 DEG C per min. The maximum reaction temperature X (oC) and the retention time Y(min) at the maximum reaction temperature preferably satisfy the relationships represented by formulas (1) to (3): Y > -0.0714 X + 15 (1); Y < -X + 210 (2); and X > 175 (3).

Description

technical field [0001] The present invention relates to a method for producing cellooligosaccharides containing oligomers with a degree of polymerization of glucose of 3 to 6 by hydrolysis of plant biomass using a carbon catalyst. Background technique [0002] Cellooligosaccharides are oligosaccharides formed by the polymerization of glucose through β1,4 bonds. In recent years, they have discovered functions such as moisturizing properties, inhibiting stickiness, imparting refreshing taste, reducing starch aging, and inhibiting protein denaturation. They are expected to be used in medicine, cosmetics, Utilization in the field of food and feed. [0003] In particular, cellooligosaccharides having a degree of polymerization of glucose of 3 or more are expected to improve the above-mentioned functionality and impart new functionality. [0004] However, the cellooligosaccharides currently used in industry are produced by enzymatic reactions, and the main components are glucose ...
