Wish-Bone salad dressing company

Look at the ingredients of their "Olive Oil Vinaigrette":

Ingredients: water, vinegar (rice wine, red wine and balsamic), high fructose corn syrup, extra virgin olive oil, soybean oil, contains less than 2% of: minced garlic*, marjoram*, orange peel, spice, salt, xanthan gum, sodium benzoate, sorbic acid, and calcium disodium edta (to preserve freshness) *dehydrated

Yum !

Given that oil and vinegar are both shelf stable and a vinaigrette is such a simple thing, why do they put all that other crap in it ?
