摘要
A simple and fast capillary electrophoresis method was used for the analysis of wheat flour proteins related to grain hardness. The study has shown that the ratio of the peak areas of two proteins, puroindolines a acid b, can be used to distinguish hard and soft varieties of breadwheat. In addition, the results indicate that hard breadwheats can be further separated into two different sub-types. This novel finding suggests that hard breadwheat may have evolved from the original soft breadwheat by two different routes. The method has the potential to provide a new diagnostic tool for wheat breeders and the milling industry. (C) 1999 Elsevier Science B.V. All rights reserved.
