Abstract
Abstract Hydrolysis of plant kingdom polysaccharides by treatment with SPS-ase preparations. SPS-ase is an enzyme adapted to hydrolyzing the water-soluble protein binding polysaccharide present in soy flour decomposed by use of conventional pectinases, which polysaccharide is believed to be widespread in plant kingdom substances. Treatment with an SPS-ase preparation can clarify juices, wines and beers, hydrolyze process wastes such as sugar beet pulp, pomace, and soy milk remanence, improve the digestability of silage, and reduce the viscosity of wort.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
36 words
A process for hydrolyzing plant kingdom polysaccharides which comprises treating a polysaccharide containing plant kingdom substance with an SPS-ase preparation, said SPS-ase being characterized as capable of degrading the water-soluble polysaccharide which binds to soy protein.
Claim 2
Dependent Claim
36 words
A process for hydrolyzing plant kingdom polysaccharides which comprises treating a polysaccharide containing plant kingdom substance with an SPS-ase preparation, said SPS-ase being characterized as capable of degrading the water-soluble polysaccharide which binds to soy protein.
Claim 3
Dependent Claim
15 words
The process of claim 1 further comprising clarifying juices, wines or beers by the treatment.
Claim 4
Dependent Claim
26 words
The process of claim 1 further comprising liquefying a polysaccharide containing process waste material by treatment an aqueous suspension of such material with said SPS-ase preparation.
Claim 5
Dependent Claim
33 words
The process of claim 1 further comprising treating an aqueous suspension of a process waste material selected from the group consisting of sugar beet pulp, pomace and remanence from production of soy milk.
Claim 6
Dependent Claim
17 words
The process of claim 1 further comprising treating fresh silage with a solution of said SPS-ase preparation.
