I will def look at ingredients on candy (not that I eat all that much) more closely because being vegetarian, I wouldn't want to injest bug parts, either.
Yes shellac is not vegan so be careful. It's also used to coat tablets (like aspiring, ibuprofen and prescription drugs). Shellac may be generically referred to as either enteric coating, pharmaceutical glaze, confectioner's glaze, resinous glaze, pure food glaze or natural glaze. So watch for those on the ingredients list. I also wouldn't eat anything that is processed, packaged or manufactored in a warehouse...as a certain percentage of bug parts are FDA approved in warehouses (unless it is a Kosher certified warehouse).
I remove M&M's from the list but Skittles (only in the UK, in the US it is made with gelatin - which is made from animal skin and bones) and Junior Mints are examples of candies that are admittedly made with shellac.
My point was that a trace amount of edible wax in a huge amount of candy is not as bad as one
might original think...when one doesn't put it in perspective to the things we eat everyday and what they contain (including candies from the store). Do you know what artificial colors (which has been banned in several countries but is used in millions of US products) are made from?
Also, the link previously about paraffin being poisonous is in reference to the paraffin wax used to make candles...which is a different product than the edible Baker's wax. Make sure to read the package and get the kind safe for ingestion.
