If he had autism he wouldn't be very social, but very shy. I don't think flapping his arms is a sign of autism, but if you're concerned about it, ask a neurologist about it, or his doctor, either way. :) â¥ Cute T â¥ Â· 9 years ago.
If it weren't for food preservatives, we couldn't enjoy many of the great foods the world has to offer. Common antimicrobial preservatives include sodium nitrate, calcium propionate, disodium EDTA, potassium sorbate, sodium benzoate, and sulfites.
Sodium benzoate is a preservative commonly used in fruit pies, jams, beverages, salads, relishes, and sauerkraut -- foods that have an acidic pH. Chemical preservatives, such as sodium benzoate are frequently used in processed foods to prevent the growth of bacteria, yeast or other nasty microorganisms that could spoil your food. When sodium benzoate is combined with water, benzoic acid is produced. Benzoic acid is the active form of the preservative - the form that protects foods. Benzoic acid is also found naturally in some fruits such as cranberries, plums, and apples.
