Compatibility of Gelatin with Broad Bean Globulin in an Aqueous Medium

The phase state of mixture of gelatin and Broad Bean globulins in an aqueous medium has been studied. Phase diagrams were determined which demonstrated the compatibility of gelatin with total globulin and of gelation with 11S globulin of Broad Beans. Results indicate that compatibility of gelatin with total globulin differs only slightly from the compatibility with 11S globulin. The increase in compatibility of gelatin with 11S globulin with increasing ionic strength is particularly interesting. As a consequence it appears possible to extend the region of the one-phase mixed compositions suitable for the production of mixed gels.
