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.
Food preservatives can be classified into two general categories: antimicrobials or antioxidants. Antimicrobials inhibit the growth of yeasts, bacteria, and molds. Antioxidants slow air oxidation of lipids and fats, which causes foods to go rancid too quickly.
