veggie burger

Ive been trying out the veggie burger recipe here and have been succesful with it. Except that customers want a vegan burger. The recipe here has sodium caseinate which is milk derived therefore not vegan. I switched to a soybean protein isolate, but it's just not working. Has anyone had any luck? Anyone done any further research in the matter? I really need some help.

From what i know, transglutaminase bind proteins that are rich in lysine and glutamine, so i suppose your best bet is to try and find some vegan protein that is rich in those to amino acids. I think i read that wylie dufresne bonded soybeans with tg so that should work in theory, so not sure why soybean protein isolate wouldn't work.

How are you adding the isolate ? Just raw in a powdered form ? You may want to add it is an emulsion by pre bowl chopping it with cold water (ice water would work best) and then drizzling with vegetable oil. This will then gel if you are steam setting or water setting your burger later on. I doubt the protein bonds will be as strong as TG though.
