Page 1 of 9 Cereal Food Application Sheet Dough strengthening Content: Benefits Products Performance Usage In industrial baking, strong stable dough is a basic requirement for optimal dough machinability and high quality baked products. Thus, dough strengthening is an important part of making high-quality bread improvers. Lipopan enzymes have good dough-strengthening properties for industrial bread-making. With Lipopan, bread improver manufacturers have enzymatic options for cost-efficient replacement of emulsifiers in a vast range of baked goods. Benefits Lipopan enzyme products unlock the dough-strengthening potential of the natural lipids in flour. The key benefits of using Lipopan enzymes for dough strengthening are: Replacement of emulsifiers allowing significant savings in ingredient costs. Good dough stability, improved loaf volume and a fine, white crumb appearance. Reduction or elimination of the acidic flavour commonly associated with some emulsifiers.

Page 3 of 9 Performance Performance of Lipopan F Lipopan F products are used in a broad range of baking processes with different grades of flour and are particularly well suited for Turkish-style, French-style and overnight fermented bread. In formulations containing special ingredients, such as milk powder, butter or other fats/oils with short fatty acid chains sensitive to lipase, Lipopan F products may cause off-odours or off-flavours. Turkish-style bread, overnight fermented bread and French-style bread are all examples of relatively long procedures where good performance is obtained even with low dosages of Lipopan F BG. Examples of typical Turkish- and French-style bread and overnight fermented bread are shown in Pictures 1, 2 and 3 and Figure 1. In these procedures, dosages of only 4-20 ppm Lipopan F BG resulted in optimum performance, which was fully comparable to the performance of DATEM. In contrast to bread without emulsifiers or Lipopan F BG, the bread with Lipopan F BG showed good volume and a very nice open bloom. FSMA FSMA + 0.3% DATEM FSMA + 6 ppm Lipopan F BG Picture 1.

Performance of Lipopan Lipopan can be used in a broad range of baking processes with different grades of flour, and is particularly well suited for straight dough and Chorleywood baking processes. Straight dough The example in Figure 2 shows that rolls and pan bread produced using straight dough process Lipopan products show volume and crumb structure comparable with bread made by using DATEM, and that Lipopan provides the same effect as Lipopan F but at lower dosage.

Chorleywood baking process Figure 3 shows that in a typical Chorleywood baking process just 40-4 ppm of Lipopan can match 0.4% DATEM in regards with volume and crumb appearance. While Figure 4 and picture 4 show that 27 ppm of Lipopan results in the same volume and crumb structure as 0.2% DATEM.

Butter tolerance Lipopan has higher butter tolerance than Lipopan F. The tolerance needs to be evaluated in each specific procedure, but in many cases up to % butter fat will be acceptable. Performance of Lipopan 0 The combination of hemicellulase or xylanase and fungal alpha-amylase is used extensively in the baking industry. The optimum effect of these products is limited due to the potential dough stickiness caused by higher dosages. Lipopan 0 BG can significantly improve dough volume without causing any dough stickiness. Therefore Lipopan 0 BG in addition to xylanase/amylase has good potential for improving the quality of breads. When used for dough strengthening, Lipopan 0 BG can partially replace distilled mono-glycerides. As shown in Picture, the crumb structure of the bread is significantly improved when Lipopan 0 BG is added. Control Pentopan Mono Pentopan Mono Fungamyl Picture.
