Observation: Organic and name brand food items appear to have less preservative based ingredients?

Over the past year I've been paying much more closer attention to ingredients in food, especially with my 3 year old son eating more then ever. I had always been a generic store brand (Walmart Great Value, Kroger brand, etc) purchaser up until recently.

While organic and store brands may not always mean better it's clear that more often then not it means less preservative based ingredients.

Here's two examples, both items my family consumes. These are just two examples, have been seeing this repeated in dozens of items.

Peanut butter

Kroger brand (food retailer here in Ohio and in the Midwest): Roasted Peanuts, Sugar, Contains 2% or Less of: Molasses, Fully Hydrogenated Vegetable Oils (Rapeseed, Cottonseed, Soybean), Salt.

Costco Kirkland organic: Dry Roasted Organic Peanuts and Sea Salt

Notes: Fully Hydrogenated Vegetable Oils are pretty bad you if you research them are often found in highly processed foods and in items to maintain shelf life. There's no comparison to the organic equivalent here.

Vanilla ice cream

Kroger vanilla bean ice cream: Milk, Cream, Sugar, Corn Syrup, High Fructose Corn Syrup, Whey, Skim Milk, Natural and Artificial Flavor, Stabilizer (Guar Gum, Cellulose Gel, Mono- and Diglycerides, Locust Bean Gum, Cellulose Gum, Carrageenan), Vanilla Bean.

Tillamook vanilla bean ice cream: Skim Milk, Milk, Sugar, Pasteurized Egg Yolks, Vanilla Extract, Tara Gum, Guar Gum, Vanilla Bean, Natural Flavor.

Notes: Once again the cheaper store brand is far unhealthier, containing high fructose corn syup, and additional additives and stabilizers.

Coffee creamer

Kroger: Water, Sugar, High Oleic Soybean Oil and/or High Oleic Sunflower Oil, Less than 2% of Natural and Artificial Flavors, Sodium Caseinate (a Milk Derivative*), Dipotassium Phosphate, DATEM, Carrageenan

Natural Bliss Vanilla: Skim Milk, Cream, Sugar, Natural Flavor

Notes: There's more additives and fat content based items in the store brand. Once again we see Carrageenan being used which itself is a controversial ingredient.
