Impact of emulsifiers on the quality and rheological properties of gluten-free breads and batters

The effects of the emulsifiers lecithin (LC), di-acetyl tartaric ester of monoglycerides (DATEM), distilled monoglycerides (DM) or sodium stearoyl lactylate (SSL) were studied in a gluten-free (GF) batter and bread formulation. Three different levels, i.e. low, medium, and high, were evaluated and compared to a control bread with no emulsifier. The rheological properties of the emulsifiers at their optimum level as well as their effect on starch retrogradation were investigated. Standard baking tests were carried out and the breads were tested over 5 days of storage. Rheological tests suggested that LC reduced the elasticity of the batter and increased the batter consistency during gelatinisation ( P
