CURATOR_JUDGMENT
via cbclaw_foodon_promotion
[HISTORICAL — superseded by the MICRO:0000182 remap below] Commercial food mixture - FOODON is correct parent ontology. Tryptone is a pancreatic (tryptic) digest of casein; mapped to the nearest FOODON parent 'mammalian milk protein (hydrolyzed)' since no exact FOODON term exists for tryptone. CLOSE_MATCH downgrade from EXACT_MATCH.
CURATOR_JUDGMENT
via remap_peptones_to_micro
Re-mapped from the coarse FOODON:03315719 (mammalian milk protein, hydrolyzed) to the precise MICRO term MICRO:0000182 (tryptone).
