Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
56 words
A PROCESS FOR PRODUCING FRUCTOSE BY FERMENTATION, WHICH COMPRISES INOCULATING AND CULTURING A FRACTOSEPRODUCING MICROORGANISM IN A MEDIUM CONTAINING SORBITOL AS A CARBON SOURCE, A NITROGEN SOURCE AND INORGANIC SALTS, THEREBY PRODUCING AND ACCUMULATING FRUCTOSE IN THE MEDIUM, AND THEN SEPARATING THE SO-ACCUMULATED FRUCTOSE, THE SAID MICROORGANISM BELONGING TO ONE OF THE GENERA BACILLUS AND PSEUDOMONAS.
Claim 2
Dependent Claim
56 words
A PROCESS FOR PRODUCING FRUCTOSE BY FERMENTATION, WHICH COMPRISES INOCULATING AND CULTURING A FRACTOSEPRODUCING MICROORGANISM IN A MEDIUM CONTAINING SORBITOL AS A CARBON SOURCE, A NITROGEN SOURCE AND INORGANIC SALTS, THEREBY PRODUCING AND ACCUMULATING FRUCTOSE IN THE MEDIUM, AND THEN SEPARATING THE SO-ACCUMULATED FRUCTOSE, THE SAID MICROORGANISM BELONGING TO ONE OF THE GENERA BACILLUS AND PSEUDOMONAS.
Claim 3
Dependent Claim
102 words
A PROCESS FOR PREPARING A FRUCTOSE-CONTAINING SWEETENING COMPOSITION BY FERMENTATION, WHICH COMPRISES INOCULATING AND CULTURING FRUCTOSE-PRODUCING MICROORGANISM IN A MEDIUM CONTAINING SORBITOL AS A CARBON SOURCE, AN INORGANIC NITROGEN SOURCE AND INORGANIC SALTS, DISCONTINUING THE CULTURE WHEN THE FRUCTOSE PRODUCED AMOUNTS TO ABOUT 20-50% BASED ON THE SORBITOL, THEN FILTERING THE CULTURE MEDIUM, TREATING WITH A MEMBER SELECTED FROM THE GROUP CONSISTING OF ACTIVATED CARBON AND ION-EXCHANGE RESIN, AND CONCENTRATING THE RESULTING LIQUID TO FORM A COLORLESS TRANSPARENT VISCOUS FRUCTOS-CONTAINING LIQUID SWEETENING AGENT HAVING A SORBITOL CONCENTRATION OF ABOUT 30%, THE SAID MICROORGANISM BELONGING TO ONE OF THE GENERA BACILLUS AND PSEUDOMONAS.
