Looking at the description posted on here its protein profile will come from Pea Protein Isolate (PP and is used in the aquatic industry as a fishmeal replacement) combined with the refined milks which when used in combination (acid & rennet caesin produce a good profile when combined maybe even in conjunction with wpc80), the yeast willmore than likely be Brocacel (digestion aid) or i know some people that are utilising high Nucleotide Yeast (more solubility and amino profile). The cheese smell could be a good quality cheese powder (normally blue cheese powder) which was a in the original Grange Mix.
Hope that helps.
