10、logical propertiesAbstractThe effects of cysteine and processing parameters (mixing speed and time) of white/whole dough viscoelastic properties were evaluated.The same amount of cysteine (20 mg/kg) was added for each mixing time (10, 15, 20 s) in order to assess its effect on dough rheological prop

11、erties. Fundamental (rheometer) and empirical (texture analyser) rheological measurements have shown that dough viscoelastic properties (ranging from more solid-like to more fluid-like) were affected by cysteine and kneading conditions even if induced changes by cysteine were substantially larger th

12、an those induced by mixing time. The cysteine addition increased the fluid-like properties of the dough; in fact, dough hardness, resistance to extension and storage modulus (G0) were lower while adhesiveness and extensibility were higher where cysteine was added.3. Results and discussion3.1. Effect

13、s of mixing time and cysteine on dough rheological Properties The mixing step permits the organisation of different conformational arrangements of the key biopolymers (particularly gluten proteins and starch) present in the system and promotes numerous interactions between dough components (Ross et

14、al., 2004; Zheng et al., 2000). The dough at optimal mixing is fully hydrated and therefore the key molecules of the system are well lubricated, thus forming a coherent viscoelastic mass. Tables 3 and 5 show the effect of mixing time on the rheological properties of the different dough systems. The

15、results are in general agreement with those of Letang, Piau, and Verdier (1999), Zheng et al. (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 maxim

16、um 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 elasti

17、c 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 stron

18、g 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 re

19、volution) 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, wh

20、ich 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 stor

21、age 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

22、. 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

23、 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5表明了混合时间对面团的流变学特性的影响。研究结果与Letang, Piau, and Verdier (1999), Zhenget al. (2000), and Ross et al. (2004) 的研究基本一致，面团的储能和能耗会在最佳的和面条件下，会随着和面时间的增加而降低。凭直觉可以得到面团储存的能量的最佳值，在这个条件下，面团

24、有最高的粘弹性。从表3和表5可以看出，所有不加半胱氨酸的样品，所有的参数（硬度，抗延展阻力，储存的能量都是面团粘弹性的重要指标）随着和面时间延长而增加且没有达到最大值。没有添加半胱氨酸的样品没有达到最大值，因为面团混合不均匀，在原型的搅拌器中，不可能20多秒时间内混合面团，此时面团变硬，很难去加工。另一方面，所有的样品，添加半胱氨酸，硬度，抗延展阻力和储存的能量在1Hz，混合时间15s的情况下，可以达到最大值。实验结果支持了这种假设，在原型搅拌器中，高速旋转的情况下，添加半胱氨酸的小麦粉，15s是最佳的混合时间。同时也证明了添加半胱氨酸可以通过降低面团的弹性和面团的醒发来减少混合时间，这跟Srinivasan et al. (2000) and AbdElmoneim and Abdullahi (2002) 的研究结果一致。 表四和五表面添加半胱氨酸可以增加面团的流变学特性。对于每一组不同的混合时间的处理，在1Hz的条件下，面团的硬度，抗延展性和存储的能量明显低于添加半胱氨酸的处理，但是粘附性和延展性更高一些。由于半胱氨酸对面团二硫键的作用，使得面团更容易伸展，加工特性增加，图一也证明了这一点。对
