WebJul 14, 2024 · Why is caffeine more soluble in methanol than water? The solubility of the two compounds decreases with decrease in polarity of the solvent used. This implies that … WebMany experts say that the less caffeine you consume, the better. Others say more than 150 mg of caffeine a day is too much, while others say more than 300 mg a day is excessive. Avoiding caffeine as much as possible is your safest course of action.

WebCaffeine, unlike 3-CGA, has a limited solubility at room temperature of 16 mg/mL46. However, all four coffees analyzed showed comparable extraction kinetics to those of 3-CGA. In all coffees sampled, fast ini- tial extraction was seen over the first 180 minutes, with a slower rate of extraction after 180 minutes.
