The overall stability of the higher temperature foam expressed in terms of foam-to-liquid ratio was also lower as initial milk temperature increased. In the case of mechanically whipped milk foams, it was observed that higher milk temperatures resulted in dispersions having a lower bubble hold-up. The increase on foam stability is most probably related to the greater extent of protein denaturation induced by increasing steam injection time.
Observation on foams formed by steam injection revealed that steam injection time does not have a significant effect on initial bubble hold-up even though it increases general foam stability. The methodology involves characterizing the foam in terms of initial bubble hold-up, foam destabilization mechanisms and kinetics. A methodology to characterize and distinguish between milk foams generated by two main methods-mechanical agitation and steam injection-is presented. The present study aims to understand the mechanisms of foam formation in milk, with a view to producing a froth that is more appealing to consumers. There are also no reliable methods to evaluate foam characteristics, since most studies to date focus on avoiding milk foaming during packaging and heat treatment, or on the behaviour of pure protein foams. Though the main appeal of such products lies in their milky frothy top, there is a lack of understanding on the liquid properties and process parameters driving froth quality. Alexander Sher, in Bubbles in FAbstractįoamed beverages, such as cappuccino, have become very popular with consumers in recent years. Therefore, it can be concluded that instant cappuccino brews also provide a substantial amount of polyphenolic antioxidants and caffeine, in the range of decaffeinated and filtered coffee. As can be seen in Figure 10.2, the ranking of antioxidant capacity of instant cappuccino brews corresponded to the TPC, CGA derivatives, and caffeine content. Additionally, it was observed that instant cappuccino brews provided higher caffeine content than decaffeinated coffee brews, almost comparable to regular espresso brews, and depended on the content of instant coffee in their composition. This was also applicable to the antioxidant capacity of cappuccino brews. This observation was, however, attributed to the presence of milk-derived compounds, which can directly interfere with accurate polyphenol determination by reducing analytical recovery, causing overestimation of milk-prepared cappuccino brews. In contrast to the results obtained for coffee brews prepared with the addition of milk, instant cappuccino brews made with milk exhibited higher TPC than those made with water. (2012) determined significant differences in the TPC of water-prepared instant cappuccino brews, with regards to the cappuccino composition (the content of instant coffee) ( Figure 10.2). It’s long been known that the decaffeinating process doesn’t eliminate 100 percent of the caffeine in coffee, but there are no standards for acceptable levels in brewed decaf.Besides coffee, instant cappuccino brews are also often consumed and can be prepared either by brewing with water or milk, depending on consumer preferences. Results varied at each chain, but the magazine found that the decaf at McDonald’s consistently had the lowest levels of caffeine.
