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.
Potassium Benzoate replaces sodium benzoate where low sodium content is required. A preservative is an additive for foods, pharmaceuticals, personal care products, cosmetics and other industrial products to reduce spoilage that air, fungi, bacteria, or yeast can cause.
