The method of claim 1 wherein the acid-neutralizing composition further comprises gelatin. The gelatin is useful in the composition for neutralizing tannic acid, an acid present in the fruit of many plants, and one of the acids present in coffee. The consumption of acidic food and beverages often results in physical discomfort in the form of indigestion and heartburn among other discomforts. Carbon dioxide dissolves in water to produce carbonic acid (H2CO3), The carbonic acid reacts with OH- to produce the carbonate ion that precipitates with calcium ion. In these methods, the acidity of coffee is reduced through the use of an acid-neutralizing composition. Low-acid coffee is a generic term used on coffee varieties purposely grown, roasted, and ground to have the least possible effect on your stomachs acidity levels.
