Bread improvers: Comparison of a range of lipases with a traditional emulsifier

This study compares three generations of lipase enzymes with the emulsifier, diacetyl tartaric esters of mono-glycerides (DATEM), on white wheat flour bread. Baking recipes with addition of DATEM (4500 ppm), Lipopan F-BG (15 ppm), Gryndamyl Exel-16 (115 ppm), Lipopan Xtra-BG (25 ppm) and Lipopan 50-BG (27.5 ppm) were test-baked after 60 and 150 min fermentations, to study their effects on the baking characteristics of volume, oven rise, crust colour, crumb texture and colour, shelf-life, flavour and aroma. The enzymes and emulsifier preparation caused significant increase in bread oven rise and specific volume with the exception of Lipopan 50-BG, which failed to improve loaf volume in the short fermentation method. There was no significant difference between other lipase enzymes and DATEM as a bread volume improver. Increase in fermentation time resulted in increase in volume in all samples, except for Lipopan-Xtra.
