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.
Sugar is also one of the common food preservatives, often used to extend the shelf life of desserts and sweet food items, such as canned fruit or candy. Sometimes natural sugar is replaced by high fructose corn syrup in many processed foods, to act as a less expensive sweetener and preservative.
