Separating gelatin from Jell-O powder

So I’ve been doing a bit more cooking while confined to my home and I wanted to make a recipe that calls for gelatin. I don’t have any and I don’t expect to be doing another grocery run for a few weeks.

However, I have two things for sure: Jell-O powder and time. The powder, from the looks of the description, is mostly gelatin, sugar, artificial coloring, and flavoring. Let’s assume for simplicity’s sake that this is the only combination, and also that I don’t care if some coloring makes it into my final product. I also won’t care if a little sugar gets in. I mostly don’t want the artificial flavoring.

I don’t remember my chemistry well (and honestly I never learned too much about physical chemistry or materials chemistry), but here are some thoughts I had:

1. DIY centrifuge. I don’t know whether this works with powders.
2. Dissolve in water and boil off some of the materials. I imagine this will require a higher heat than I can produce, seeing as Jell-O needs to be boiled in the first place, and I don’t know what it’ll do to the gelatin.
3. Dissolve in something in which gelatin is (or isn’t) soluble, then filter. I don’t know what this would be.
4. Dissolve in water and precipitate out undesired substances via a chemical reaction. I don’t know what this would be either.

This task is probably impossible for me with my current experience and materials. Even if so, I hope it’s an interesting question to ponder.
