FOOD SCIENCE factoids in orange text:

(1) Edible acids!

Salt and vinegar potato chips! Oranges! Lemons! Grape juice and wine! I'm not going to list all the foods and their natural acids. (Well, salt-and-vinegar potato chips aren't totally "natural", but they are addictive to me and I have to keep them out of my sight.)

Below is a table for your eyes only. Acids are super-important for both the natural preservation, but also contribute immensely to the flavor of the food. A whole book could be written on food acids (and likely another book on food alkali.)

A lot of "bad bacteria" such as Clostridium botulinum, Salmonella, E. Coli and Listeria are inhibited by acids.

Here are two tables you'll hopefully find informative:

Food Acid Examples of Foods Toxicity Information Metabolism
Citric
Lemons, limes, oranges, strawberries, tomatoes Generally safe. Excessive amounts may cause gastrointestinal discomfort. Converted to intermediates in the citric acid cycle; produces ATP
Malic
Apples, pears, cherries, grapes Generally safe. Excessive intake may cause gastrointestinal irritation. Converted to oxaloacetate in the citric acid cycle; involved in gluconeogenesis
Tartaric
Grapes, tamarind, bananas (cream of tartar) Generally safe in typical amounts. High doses may cause gastrointestinal issues. Metabolized in the liver; broken down into simpler compounds for excretion
Acetic
Vinegar (e.g., apple cider vinegar), pickles, fermented foods Safe in small amounts. Large amounts can cause digestive issues and damage tooth enamel. Converted to acetyl-CoA in the liver; enters citric acid cycle
Lactic
Yogurt, kefir, sauerkraut, fermented pickles, sourdough bread Safe and well-tolerated. High concentrations might cause digestive upset in sensitive individuals. Converted to pyruvate in the liver; involved in Cori cycle and gluconeogenesis
Formic
Some fruits and vegetables (minor amounts), honey Generally safe in small amounts. High concentrations can be irritating or toxic, but not typically encountered in food. Metabolized in the liver; converted to carbon dioxide and water
Oxalic
Spinach, rhubarb, beet greens, Swiss chard Safe in moderate amounts. High intake can interfere with calcium absorption and contribute to kidney stones in susceptible individuals. Metabolized in the liver; converted to carbon dioxide and water; can be excreted in urine
Phytic
Whole grains, nuts, seeds, legumes Generally safe. High amounts can inhibit mineral absorption but are usually not a concern with a varied diet. Metabolized by intestinal microbes; partially broken down to inositol and phosphates; mineral-binding effects

 

Bad Bacteria Preservation effectiveness of Food Acids
Clostridium botulinum Inhibited at pH below 4.6; stronger acids such as acetic and citric and effective
Salmonella Inhibited to some extent by lower pH; acids reduce growth but may not eliminate risk.
E. coli Growth reduced at pH below 4.5; acids are effective in inhibiting growth.
Listeria
Inhibited at lower pH but can survive in mildly acidic conditions; acids help but are not fully effective.

Food acids are a useful tool for controlling bacterial growth, but they are often used in combination with other preservation methods for better safety and effectiveness.
