    Abstract: Provided is a preparation process of diglycerides which comprises reacting a fatty acid or lower alkyl ester thereof with glycerin in the presence of an immobilized partial glyceride lipase while removing water, which is generated upon reaction, out of the system. The reaction is preferably terminated when the acid value (AV) of the reaction mixture satisfies the following range: 50R-60>AV>70R-150 (with the proviso that AV>0). The present process makes it possible to efficiently prepare a high purity of diglycerides without impairing lipase activity even under reduced pressure. The present process is effective without being influenced by variations in reaction conditions such as fatty acid/glycerin ratio, reaction temperature or enzyme concentration. Particularly, even when the fatty acid/glycerin ratio is high, a high purity of diglycerides can be produced at a high reaction yield.

    Abstract: PCT No. PCT/JP96/01400 Sec. 371 Date Jan. 28, 1997 Sec. 102(e) Date Jan. 28, 1997 PCT Filed May 24, 1996 PCT Pub. No. WO96/38527 PCT Pub. Date Dec. 5, 1996The present invention relates to an enzyme-containing granulated substance comprising an enzyme-containing particulate substance and a coating layer which is formed on the particulate substance and comprises (a) water-insoluble or hardly water-soluble inorganic particles having an average particle diameter of 1 to 100 mu m, (b) water-insoluble or hardly water-soluble inorganic particles having an average particle diameter of 0.01 to 0.8 mu m and (c) a binder, and a preparation process thereof. The enzyme-containing granulated substance is not only high in productivity but also low in dusting characteristics and high in storage stability, and is hence useful as a formulation ingredient for detergents, in particular, bleacher-containing detergents.
