(2000), and ross et al. (2004), who showed that g0 (storage modulus) and g00 (loss modulus) of dough decreased when subjected to mixing times over the optimum kneading value. the result of g0 having a maximum value at the optimum mixing time is intuitive, in that the dough has the highest elasticity at optimum kneading.from tables 3 and 5 it is possible to observe that, for all samples not including cysteine, all the parameters (hardness,resistance to extension and g0) indicative of coherentand elastic dough increase with mixing time without reaching a maximum value. in the samples without cysteine, the maximum value was not reached because the dough was not mixed properly; with the used prototype mixer it was impossible to mix the dough for more than 20 s, because of this the dough became strong and too difficult to process.on the other hand, in all samples (white and whole) where cysteine was added, hardness, resistance to extension and g0 at 1 hz reached maximum values at 15 s of mixing time. the result supports the hypothesis that in those conditions (prototype mixer with high speed revolution) and with this kind of raw material (white and whole flours plus cysteine), 15 s correspond to the optimum mixing time. this also confirms the fact that cysteine addition reduces the mixing time by decreasing the elastic (solid-like) component of the dough and aiding in dough relaxation, which is in accordance with srinivasan et al. (2000) and abd elmoneim and abdullahi (2002).tables 4 and 5 show that cysteine addition increased the fluid-like properties of the dough. for each mixing time,and for both kinds of samples (white and whole), dough hardness, resistance to extension and storage modulus (g0) at 1 hz were lower while adhesiveness and extensibility were higher when cysteine was added. as a consequence of the effect of cysteine on disulfide bonds the dough becomes easily extensible and machinability increases. this hypothesis is supported also by the result reported in fig. 1, where the turns/minute of the prototype mixer during kneading time are showed. for both samples, with and without cysteine,motor power loss during mixing can be observed. in dough without cysteine the power loss was higher than 15%, while in the sample where cysteine was utilised the power loss decreases (7%), thus indicating increased machinability.3. 实验结果与讨论3.1 混合时间和半胱氨酸对面团的流变学性质的影响混合的步骤是主要的聚合物形成不同的构象，进而形成一定粘弹性的面团。表3和
