Abstract: The object of the present invention is to provide a dispersion stabilizer that can minimize coagulated precipitation of a protein under acidic conditions, especially in the pH range of around pH 5 which is closer to neutrality than the range around the isoelectric point of the protein. It is possible to stabilize dispersion of protein particles around pH 5, and thus prepare an acidic protein food, by using a legume seed polysaccharide esterified with a succinic acid derivative having a hydrocarbon chain bonded to the 2-position carbon of succinic acid or succinic acid. The hydrocarbon chain of the succinic acid derivative preferably has 2 to 18 carbon atoms, and is most preferably an octenyl group. The esterified legume seed polysaccharides also have high emulsifying ability.

Abstract: According to the 3D-CAD system of the present invention, basic graphic elements (PL, LL, SL, VL) are set based on linear, area or volume coordinate parameters, and the plurality of basic graphic elements are continuously connected to generate a basic graphic. The basic graphic elements constituting the generated basic graphic are continuously differentiable even after deformation, thereby generating a desired solid graphic (identical topology graphic). By using these patches for approximately expressing all surfaces, the surfaces are handled consistently, the data quantity describing the graphics is greatly reduced, and the load of operational processing of the computer is reduced. Whether or not an element can be deleted is determined based on a reference counter RC showing whether said element is the component of another element.
