The original flavor of Baked Lays chips is suitable for vegans as it does not contain any animal-derived ingredients. However, the same cannot be said for all of the other flavors of Baked Lays. Other flavors, like barbecue and sour creme and onion are not vegan, as they do contain animal-derived ingredients.
The full ingredients list for the original Baked Lays flavor is: Dried Potatoes, Corn Starch, Corn Oil, Sugar, Sea Salt, Soy Lecithin, Dextrose, and Annatto Extracts. There is nothing within the ingredients that would make this product unsuitable for vegans.
However, the barbecue flavored Baked Lays are not vegan due to the fact that the flavoring contains milk-based products. Additionally, the sour creme and onion flavored Baked Lays are not vegan because they contain milk-based ingredients, including milk and sour cream. So, of the three available choices when it comes to Baked Lays, only the original flavor is suitable for vegans.
