CURATOR_JUDGMENT via cbclaw_foodon_promotion

Commercial food mixture - FOODON is correct parent ontology. Trypticase peptone is a pancreatic digest of casein (equivalent to tryptone). Often bundled in BBL/BD Trypticase Soy Broth formulations which also include soy peptone. Mapped to generic FOODON parent 'protein hydrolyzates' since no exact FOODON term exists. CLOSE_MATCH.

CURATOR_JUDGMENT via manual review of MICRO ontology coverage

MICRO has the exact label; FOODON:03315306 was a parent.
