| Abstract: | Macromolecular integrity of egg yolk lipoproteins is an essential prerequisite towards retaining cake quality of Madeira cakes and fatless sponges. In Madeira cakes, the low density lipoprotein of yolk is the major determinant of yolk function. In fatless sponge-cake making, it assists aeration and foaming. The high density yolk lipoprotein inhibits aeration but helps to retain air whipped in by other egg constituents. Implications of these findings are discussed in terms of possible modes of action of lipoproteins during cake making. |
