摘要:
This invention provides a novel process for producing cyclodextrin by reacting cyclodextrin glycosyl transferase having an optimum pH on the alkaline side with gelatinized starch. According to this invention, cyclodextrin can be obtained in the form of a pure crystal in a high yield by reacting a glucomylase with the reaction mixture liquid formed by the above enzymatic reaction to decompose unreacted starch, concentrating the liquid, adding a small amount of cyclodextrin as a seed crystal and recovering the precipitated cyclodextrin.

摘要:
The present invention relates to a novel process for recovering cyclodextrins, characterized in that a solution containing cyclodextrins as well as starches, dextrins, reducing sugars and the like is brought into contact with a hydrophobic, synthetic adsorption resin comprising a porous polymer to adsorb only cyclodextrins, the cyclodextrins thus adsorbed being eluted thereafter with water while being heated to separate and recover said cyclodextrins.

摘要:
An encrypted-traffic discrimination device includes an input interface, a flow discrimination section, a data accumulation section, a selective data calculation section, a calculation result determination section, and an output interface. The flow discrimination section discriminates the input traffic into separate flows based on at least a transmission origin address and a transmission destination address. The data accumulation section accumulates characteristic amount data of the traffic for each of the separate flows. The selective data calculation section executes an evaluation computation utilizing specific data from the characteristic amount data. The calculation result determination section that, based on a calculated evaluation computation value, executes threshold value determination to determine whether or not the traffic is encrypted, and, if the traffic is determined to be encrypted, which encryption format the traffic is encrypted with.
