Have you done a search for the information you seek? What efforts have you put into looking for this prior art? – Ron J. Feb 12 at 11:28
This is looks like a fairly labor-intensive search. Could you help us by narrowing it down to particular amino acids or vitamins, at least for a starting point? – Yorick Feb 13 at 14:47
Dear Friends, I have searched extensively using various strategy and key strings on TI ...but separate fat based coating of free amino acid and vitamin followed by combine fat coating feature is not available in patent database...i want to know any such reference in non-patent database. – KAnalysis Feb 14 at 7:56
