Pillsbury

Information gathered on Nov 25, 2008

According to the representative over the phone (who asked their nutrition  expert and then called me back).

All glycerides used in their products are of vegetable origin.

The sugar used in their products may or may not be vegan.

"Enzymes" are not vegan.

The Original Flavor Crescent Rolls are vegan.

Though they were nice to me, they were unwilling to look up more than one or two products for me, so this is all the information I was able to get.  As I was asking only about their refrigerated bread products, I don't know for sure whether or not this information is applicable to their other product lines.
