Fig. 1. Mean and interactions plots with LSD intervals. A and B: mean values for the batter relative density according to the improver incorporation and the fat replacement level,respectively; C and D: interactions between the fat replacement level and the improver incorporation for batter’s G0 and G00 , respectively. Improver incorporation (g/100 g of flour): 0 (none), L1 (lipase 0.003 g/100 g), L2 (lipase 0.006 g/100 g), E1 (emulsifier 0.5 g/100 g), E2 (emulsifier 1 g/100 g).
