I downloaded the 114 pages of Gras exemption claim that Nestle submitted in 2000 (and approved in 2002) for the use of Bifidobacterium, Lactobacillus and Streptococcus thermophilus in infant formula and the expert statements. Given that Nestle have been working with Blis on possible use of K12 in infant formula it would seem likely that Nestle will do much of this detailed preparation work. There were over 40 pages of references to supporting journal articles! This suggests we can expect the Gras approval to be a slow and measured process.
