That's exciting!

These are good alternatives. But I do look forward to hearing if you're able to make marshmallows from marsh mallow (Athaea officinalis) root!

There is quite a debate, but early surviving recipes seem to have been gelled with fruit pectin & sugar, and mastic gum was also used for flavour as well as consistency later on.

'Corn' is a very old word indeed, which means roughly, cereal grain that is a regional staple of a country. As far as I can tell, refined culinary starch powder ('cornflour') can be made from various regionally common plants, including wheat or maize ('the corn of the New World', see also 'barleycorn'). So people who need gluten-free cornflour need to check carefully!
It's said that Hacı Bekir opened a confectionery shop in Constantinople in 1777 and sold loukum at that time. Pure culinary starch made from maize was patented by John Polson of Brown & Polson in 1854 as 'Patented Corn Flour', so over 80 years later. All very interesting!
