According to the invention, L-arabinose with a mass percentage of 1-10% is added into crystal refined sugar, wherein the addition of the L-arabinose is carried out in a manner of a solution with a mass percentage concentration of 40-80%. The materials are sufficiently well mixed; the mixture is dried until a water content is below 0.8%; and the material can be manufactured into sugar cubes.
