E471s (Mono & di glycerides of fatty acids) are always Halal [for Hanafis]

because it undertakes istihalah (change of nature and quality) as is the case of vinegar, which is halal for hanafis regardless of the origin (alcohol).

I think the jami'at ul muftiyeen of SA or Mufti Husain (hafidhahullah) published something on this years ago, but can't find this now.

So far I found this post by Mufti Husain Sahab, in which actually, E471s are implicitly confirmed to be not permissible if they come from animal sources:
