Does boiling destroy caffeine?
Boiled coffee had caffeine contents equal to or greater than filtered coffee, depending upon the length of boiling time. The variable caffeine contents in coffee resulting from the mode of preparation should be recognized and addressed by both food composition data bases and epidemiologists. Caffeine is a stable compound. It is produced in the bean when the coffee seed matures, and it likes your coffee rather a lot. Reheating coffee at home doesn’t alter the number of caffeine molecules it contains.Caffeine remains heat-stable up to 460°F (238°C), a temperature higher than the typical range used for cooking and baking, which is 300 to 425°F (149 to 220 °C). That means recipes containing coffee, tea, or espresso powder do have some caffeine.Caffeine remains heat-stable up to 460°F (238°C), a temperature higher than the typical range used for cooking and baking, which is 300 to 425°F (149 to 220 °C).

Does caffeine dissolve in water?
Caffeine (Figure 1a) being one of widely used alkaloids, can either be extracted from various sources or obtained commercially [34,35]. Caffeine is readily soluble in water (20 g/L at room temperature and 660 g/L at boiling temperature). The solubility in ethanol is relatively high (15 g/L). Caffeine powder is soluble in water. I like to add it to the heated water phase of formulations. It is not soluble on its own in oil, so you would require an emulsifier in this case.
Is caffeine acidic or alkaline?
The bottom line. With an average pH of 4. While this doesn’t present a problem for most coffee lovers, the acidity can negatively affect certain health conditions in some people, such as acid reflux and IBS. H of Coffee The potential of hydrogen or pH value of coffee on average stays between 4. A low acid coffee has a pH value closer to 5. H scale.
