    • This invention relates to a process for readily and efficiently preparing L-rhamnose with the use of a marine alga belonging to the family Monostromaceae, Ulvales. According to the process of the present invention, rhamnan sulfate is extracted from a marine alga belonging to the family Monostromaceae such as Monostroma nitidium Wittrock and the obtained extract is hydrolyzed by adding acid(s) thereto followed by heating or treating thereof with a cation exchange resin followed by heating to thereby give a solution containing free L-rhamnose. Since the solution thus obtained contains a large amount of salts, the removal of these salts is significantly important in the preparation of L-rhamnose. In the present invention, an effective process therefor is combined with a conventional method by using an ion exchange resin to thereby establish an efficient desalting process. Further it is effective to elevate the purity of L-rhamnose by adding baker's yeast, which selectively ferments various sugars, to the solution containing L-rhamnose. The present invention makes it possible to economically prepare L-rhamnose. Thus a large amount of the same can be supplied as a raw material to the fields of pharmaceuticals, agricultural chemicals and food.

    • [Object]
      It is intended to provide a crystalline maltitol powder less prone to consolidation, which is free from the formation of a lump during delivery or storage thereof, does not require pulverization or re-classification in use, is easy to handle in transfer, package opening, addition or mixing to another foodmaterial, and so on, and allows for automated transportation and so on.
      [Means for solving the object]
      The crystalline maltitol powder less prone to consolidation is obtained by charging crystalline or powdery maltitol into a shelf type dryer, a tunnel-type dryer, a cylindrical container, or the like and subjecting the equipment or container to a treatment wherein an air having a temperature of 30 to 33°C and a relative humidity of 5% is allowed to flow into the equipment or container from one side thereof and withdrawn out of the other side thereof at a space velocity of 11 to 12 for consecutive 24 hours. Even when the relative humidity is 45%, the crystalline maltitol powder less prone to consolidation can be obtained by combining therewith other conditions such as an appropriate space velocity of the feed of air and an appropriate treatment duration.
