Abstract

One factor that influenced colloidal structure is the composition of water, oil, and surfactant in the emulsions. This study aims to build a Winsor phase diagram of a mixture of water, eugenol, and Tween 20 and understand the physical differences in a range of micellar structures from the different compositions of the combinations. There were eleven samples with varying compositions of water, eugenol, and tween 20, and then were mixed and observed in parameters such as phase, appearance, and consistency. The results showed that the emulsion's compositions ingredients affected the character of the final emulsion. There were three categories of emulsions as described in the Winsor phase diagram. Water in oil (w/o) microemulsion was formed in the higher oil composition. In contrast, the lower oil content was macroemulsion/ coarse emulsion. The balance of oil and water composition was categorized as a bicontinuous microemulsion. This diagram will further help in constructing the suitable emulsion category for specific purposes.

Abstract

Food foams provide texture and structure for many food products, such as meringues. Meringues, a fundamental of culinary arts,  commonly consist of whipped egg white and sugar and have about most of the air phase. These types of composition allow for making different products with the same ingredients; thus, meringue design is essential to investigate foam stability and ability. This study aims to examine the foam stability of meringue using the different components such as protein as emulsifiers (egg white and gelatin) and the composition of sugars (icing and granule) on the foam stability and formation of meringue. Using gelatin as an emulsifier showed the foam more stable than egg white (>24 h), and adding the icing sugar with gelatin made the foam texture smoother. On the other hand, foam formation was faster when using emulsifier egg white, but stability was less than gelatin. The more stable foam produced by the combination of emulsifier and sugar ingredients would provide a better texture of meringue after baking, a smooth surface, no hole, and a more crunchy sweet taste. It was concluded that the composition of the ingredients and type of emulsifier would affect the stability and ability of foam, resulting in the character of the meringue after baking.
