Popis: | The changes of some functional properties - solubility, emulsifying and foaming properties, heat-induced aggregation - of a native rapeseed globulin preparation after succinylation has been studied. In correspondence with the results obtained with the purified rapeseed 12 S globulin and other globulin preparations from plant seeds, a total blocking of the amino groups of the rapeseed globulin could not be attained. The highest degree of modification reached was 83%. The unmodified protein has high foam capacity and stability. Succinylation until 61% did not change these properties. The emulsifying activity and emulsion stability were slightly improved after a modification at a low or moderate level. The heat-coagulation of the native protein is depressed by increasing succinylation. |
