Fermentation process recipe

Using the bulk fermentation method produce a control sample to the standard recipe and a test sample without adding sugar. Compare the two batches to see if adding sugar speeds up the process, checking the effects on yield, loaf shape, loaf volume and product taste. 

As with fermentation and downstream processing, precise formulation recipes are... 

As in the steady-state simulation of continuous processes, it is convenient to convert from a process flowsheet to a simulation flowsheet. To accomplish this, it is helpful to be familiar with the library of models (or procedures) and operations provided by the simulator. For example, when using SUPERPRO DESIGNER to simulate two fermentation reactors in series, the process flowsheet in Figure 4.25a is replaced by the simulation flowsheet in Figure 4.25b. In BATCH PLUS, however, this conversion is accomplished without drawing the simulation flowsheet, since the latter is generated automatically on the basis of the recipe specifications for each equipment item.

The aroma is influenced by the recipe but also by the fermentation, e. g., the Strecker aldehydes increase and those from lipid peroxidation decrease if the dough matures at lower temperatures (Table 15.60). An extension of the kneading process...
