A process for preparing a phosphoric ester having reduced odor, comprising contacting a phosphoric ester with at least one of an inert gas and steam at 100&deg; to 160&deg; C. in a packed tower; a process for preparing a phosphoric ester having reduced odor, comprising repeating a set of processes comprising (A) heating a phosphoric ester, and contacting the heated phosphoric ester with at least one of an inert gas and steam; and (B) cooling the phosphoric ester obtained in the step (A); a process for preparing a phosphoric ester having reduced odor, comprising adding water to a phosphoric ester, and distilling water from the phosphoric ester under reduced pressure; and a process for preparing a phosphoric ester having reduced odor, comprising reacting an organic hydroxy compound with a phosphorylation agent, while introducing an inert gas into the mixture of the organic hydroxy compound and the phosphorylation agent. The phosphoric ester is useful for, for instance, a shampoo, a cleaning agent, a facial cleansing agent, an emulsifier, and the like.

A process for preparing glucose-1-phosphate from an .alpha.-glucan and orthophosphate using a phosphorylase immobilized onto an anion-exchange resin is disclosed. The anion-exchange resin used is a synthetic polymer resin into which an anion exchange group; a primary to quarternary ammonium group, a phosphonium group, or a sulfonium group, is introduced. This type of immobilized phosphorylase ensures (i) an effective utilization of phosphorylase, (ii) a higher reactivity of a higher absorbance of the phosphorylase to the resin, (iii) an excellent phosphorylase activity retention performance, and (iv) a higher physical strength of the resin.

Immobilized phosphorylase

Fat or oil is hydrolyzed with water and lipase effectively by supplying the fat or oil and water continuously each at a constant rate or semicontinuously in portions and simultaneously withdrawing a solution containing fatty acid(s) and an aqueous solution containing glycerol formed by the enzymatic reaction from the reaction system continuously at the same rates as those of the supplied fat or oil and water respectively or semicontinuously in portions to thereby maintain the glycerol concentration in the aqueous phase of the reaction system constant within a range of 10 to 40% by weight.
