Like any new identified edible
mushroom or wild unknown
fruit.
I would check in with my body often.
The usual rub it on your skin, then mouth, then tongue, then a small bite, wait a couple hours ..... then after a week, eat a ton of it, or stop when you notice your throat/belly/poop/skin tell you it id enough.
So the short
answer is to start very small and slowly increase it. You have a few months to figure it all out. Also you are being smart by double checking and asking
online. I feel the same way about eating raw amazake/koji
It is mostly made of fibre, so I can make you 'go' if you have been avoiding fibre for a while.
Going forward you can temporary store your scoby in some sugar+water, while you cut of a small piece to slowly eat it.
