"Kosher" gelatin in Yogurt! Is this an oxymoron?

So I was looking at the ingredient list of some popular flavored yogurt brands, (like Dannon) and what do I see… but “kosher gelatin” on the list. I looked at several brands and noticed the same thing. As far as I can tell, this is a recent development, I’ve never noticed gelatin in yogurt before. This was a source of some concern for me because I don’t eat beef products, and gelatin is usually made of inedible parts of beef.

Isn’t it impossible to mix gelatin with yogurt and still be kosher?
Could gelatin mixed with a milk product ever be a kosher food?
I understand there are such things as “gelatin substitutes” made from plant or algae sources, but always thought “gelatin” is a very specific animal product.

No. There are many thickening agents past gelatinous beef-related animal products that could permit Kosher consumption of thickened yoghourt. You could even have a beef-gelatin thickened yoghourt made of goat’s milk.

A Google search for “kosher gelatin” finds many articles on this: for instance, here. There are a number of ways around the milk-meat problem in this situation. Fish-derived gelatin is one possibility. Another is that (in the view of some authorities) hides treated by correct kosher procedure aren’t considered as meat, therefore hide-derived beef gelatin can be OK.

Just because one of the ingredients is kosher does not make the entire dish kosher.

Is the yogurt marked as being kosher or just the gelatin?

The upshot is, if it says “gelatin” it’s from an animal source. There is no such thing as gelatin from a non-animal source.

On a somewhat related subject, this thread discusses kosher cheese and kosher rennet.

There is a thickening agent called “agar agar” made from seaweed. It is vegetarian and kosher. I don’t eat it cause anything the texture of gelatin gives me the creeps.
