In the introduction to the study of meringue preparation, it is essential to provide a brief background on the behavior of egg proteins, which play a crucial role in forming stable meringues. Egg proteins, primarily ovalbumin, undergo denaturation and coagulation when subjected to various processes such as heating, beating, and mixing with other ingredients. For instance, when egg whites are beaten, the proteins unfold and form a network that traps air, creating foam. This process is fundamental in producing the characteristic stiff peaks of a well-made meringue. Heating eggs causes proteins to denature and coagulate, which can affect the texture and stability of the final product, while beating egg whites incorporates air and alters protein structure to produce volume and stiffness (McGee, 2004; McNutt, 2016). Additionally, mixing egg whites with sugar and acids influences their stability; sugar stabilizes the foam by increasing viscosity, and acids such as cream of tartar improve foam stability by affecting protein unfolding (Cauvain & Young, 2015). Several factors have been reported to affect the stiffness and stability of beaten egg whites, including the temperature of the eggs, the speed and duration of beating, the presence and concentration of stabilizers like sugar and acid, and the freshness of the eggs (Jellinek, 2012; McNutt, 2016). These variables interact to determine the final quality of the meringue. Understanding their roles is vital for producing an ‘ideal meringue mix’.

The art of creating the perfect meringue hinges significantly on the behavior of egg proteins, which are sensitive to various processing conditions. Egg proteins principally consist of ovalbumin, ovotransferrin, and other minor proteins that undergo structural transformations during physical and chemical treatments. These transformations influence the ability of egg whites to foam and develop stiffness, which are critical attributes for a successful meringue (McGee, 2004). When egg whites are beaten, the mechanical energy causes proteins to denature, unfold, and form a cohesive network that entraps air bubbles, leading to foam formation. This process is influenced by the degree of agitation, the temperature of the egg whites, and the presence of stabilizers such as sugar and acids. Heating egg whites beyond certain temperatures causes irreversible protein coagulation, which can diminish foaming capacity (McNutt, 2016). In contrast, beating egg whites at optimal temperatures—usually around 20-25°C—facilitates protein unfolding without premature coagulation, resulting in a more stable foam with fine, stiff peaks (Cauvain & Young, 2015). The addition of sugar and acids enhances foam stability by influencing protein structure and the viscosity of the surrounding liquid. Sugar, for example, increases the viscosity of the foam and retards the coalescence of air bubbles, while acids like cream of tartar promote protein unfolding, leading to increased foam stability (Jellinek, 2012).

Research indicates that the most critical factor for achieving an 'ideal meringue' is the temperature of the egg whites prior to beating. Eggs at room temperature tend to produce a more stable and voluminous foam compared to cold eggs, as warmer proteins denature more readily and form a finer network. Moreover, the speed and duration of beating are vital; over-beating can cause the foam to collapse, while under-beating results in a weak meringue that lacks volume and stiffness. The amount and type of stabilizing ingredients also markedly influence the final product. Sugar content, in particular, needs to be optimized—too little sugar results in a less stable foam, while excess sugar can make the meringue overly dense and sticky (McGee, 2004; Jellinek, 2012).

In conclusion, while multiple factors contribute to the optimal stiffness and stability of meringue, temperature of the egg whites before beating emerges as the most important. Proper temperature ensures better protein denaturation and stable foam formation, which are foundational to achieving the desired texture. Combining this with appropriate whipping techniques and stabilizers yields the ideal meringue mix that is light, stiff, and resilient—qualities essential for high-quality baked confections.
