Figure 4 Dependence of the relative shelf life of muffin (contour lines) on tartaric acid and potassium sorbate contents with sugar and glycerol fixed at their basic levels (90 g and 4 g, respectively, by 100 g flour and starch). Thirty of the 56 breads tested developed rope spoilage within 5 days; the high-type loaves were affected by rope spoilage more than the low-type loaves. The coded and natural values of design factors are shown in Table 2. (1) and data obtained from Table 2.

At first the liquid ingredients were mixed for 15 minutes at the first speed of the mixer. Rope spoilage of wheat bread was inhibited by adding 20-30 g of sourdough/100 g of wheat dough if the sourdough was fermented with Lactobacillus plantarum VTT E-78076,Pediococcus pentosaceus VTT E-90390 or Lactobacillus brevis (commercial starter culture) and the pH values of sourdoughs were adjusted below 4.0 and the amount of total titratable acidity value was >12. Mould spoilage I will make some small straight loaves, bun size, use the proofing oven setting (50min at 40c) to temp fate.
