Finally, the ground coffee bean and an acid-neutralizing composition mixture is brewed with water to provide a brewed coffee having reduced acidity. Using paper filters has also been shown to reduce acidity as they remove excess oils. Neutralization does not necessarily mean attaining neutral pH (ie., pH 7), rather, neutralization refers to the equivalence point for a particular acid-base reaction and will depend upon the respective strengths of the particular acid and base, their relative concentrations, and the buffering properties of the solution containing the acid and base. By Robin Wasserman. A method for decreasing the acidity of an acidic food or acidic beverage, comprising adding an acid-neutralizing composition to the acidic food or acidic beverage, wherein the acid-neutralizing composition comprises calcium carbonate, potassium hydroxide, magnesium hydroxide, and potassium chloride and wherein the acid-neutralizing composition does not impair the flavor, aroma, and taste integrity of the acid food or acid beverage. All coffee beans start out the same little green bean; it's the roasting process that determines the color and just how much acidity is retained. irritation eyes, skin, respiratory system; cough, sneezing; eye, skin burns; vomiting, diarrhea Target Organs Eyes, skin, respiratory system Personal Protection/Sanitation ( See protection codes) Skin: Prevent skin contact Eyes: Prevent eye contact Wash skin: When contaminated Remove: When wet or contaminated Change: Daily Coffee is so acidic because its filled with organic acids, such as citric, malic, acetic, and chlorogenic acids.
