| Abstract: | The factors responsible for the poor breadmaking quality of the high yielding wheat cultivar, Maris Huntsman, have been studied by fractionation of its flour, followed by reconstitution and small scale test baking. Interchange of components with those from quality Canadian Western Red Spring (CWRS) wheat demonstrated the unique importance of the gluten component. Further fractionation revealed that the proportion of ‘residue protein’, i.e. protein insoluble in lactic acid solution, was much lower in Maris Huntsman than the CWRS. However, no improvement in quality resulted when this deficiency was overcome by the addition of extra residue protein derived from Maris Huntsman. Other studies involving interchange of Maris Huntsman and CWRS gluten components showed that there is a lack of quality in both the lactic acid-soluble and -insoluble components of Maris Huntsman gluten. |
