We touched on hidden animal ingredients briefly when talking about the gelatin problem, but there are a number of other animal products in food that you might not suspect just based on the name. Here’s a roundup of some common ones. Feel free to add any you know of in the comments!

Gelatin – made from boiled skin, cartilage, and bones
Sugar – conventional sugar is often processed with bone char to whiten it
Isinglass – used in fining wine, this is made from fish bladders
Casein – a milk protein found in some non-dairy cheeses
Albumin – egg whites
Cochineal – found in some red fruit juices, made from insect blood (also known as carmine, natural red #4, or crimson lake)
Lactic Acid – unless they specify that this is plant-derived or vegan, it could come from blood or muscle tissue
Whey – another milk derivative
