Yes. It’s very helpful when producing things that need a degree of caramelisation - a few of us on the what have you eaten today thread in the low carb section of the forum have experimented and it works far better than erythritol for producing caramel. However for ordinary sweetening purposes I don’t see an advantage (it’s more expensive than alternatives). Minimal impact on BG in my experience.
I think this is a sugar substitute product commonly used and marketed in Japan. I’ve never tried myself but the product seems very popular and safe as well.
