Isinglass is made from sturgeon
air bladders. In other words, it's more like a lung then a bladder. It's used as a clarifying agent in white wines and some beers (like Guinness.) It's also filtered out before the wine is bottled. I used to work in the wine industry and I never saw it used in red wines. More often then not though, egg whites and milk were used instead of isinglass since they are cheaper.
I don't typically buy convenience foods anyway, but I'm more concerned with synthetic chemicals then with things that come from natural sources.
