The ionization energy of Na is 495.8 kj/mol vs K has 418.8 kj/mol. Typically, under these conditions, the deacidification is accompanied by saponification of coffee oils resulting in alteration of the coffee's flavor and aroma. In the method, an acid-neutralizing composition comprising calcium carbonate, potassium hydroxide, magnesium hydroxide, and potassium chloride is utilized to produce a brewed coffee having a pH of from about 5.7 to about 6.1. Similarly to the phosphorus compound in the question, even strong bases generally react only with the former hydrogen atom, at least in water solution, so for instance potassium formate is $\ce{KCHO2}$ or $\ce{HCOOK}$. Accordingly, the coffee brewer may add more or less of the acid-neutralizing composition as desired.

The acid-neutralizing composition of the present invention may be formulated in a variety of ways. A process for preparing a better tasting coffee involving an intermediate step of treating partially roasted coffee beans with an aqueous alkaline solution of a foodgrade base, such as sodium hydroxide, ammonium hydroxide, calcium hydroxide, or ammonium bicarbonate, prior to final roasting is also known. As used herein, the term "antacid activity" refers to the ability of a substance to neutralize and/or to buffer an acid. A preferred dispersing agent useful for smooth dispersal of the composition in solution is carboxymethyl cellulose. Since the caffeine inside the coffee beans is tied to many acidic compounds, its natural for many people to assume that decaf coffee is less acidic. 1. In this example, a representative acid-neutralizing composition of the present invention is described. Most fruit juices and sodas are significantly more acidic than coffee so why doesn't a glass of apple juice require you to down a sleeve of antacids? "}},{"@type":"Question","name":"How acidic is coffee with cream? In another aspect of the present invention, an acid-neutralizing composition is disclosed.
