Low pH, microbiologically stable, unpasteurized food compositions with reduced sourness and reduced salt content and methods of making same are provided. These food compositions are prepared without receiving a pasteurization or other heat treatment by acidifying a foodstuff with a membrane acidic electrodialyzed composition, and/or addition of edible inorganic acids and/or their metal acid salts, to provide low pH values of about 4.6 or less, wherein the total organic acid content is 0.22 moles per 1000 grams of food composition or less, effective to enhance microbiological stability yet without introducing an objectionable sour taste or otherwise adversely affecting organoleptic properties of the resulting food compositions.
