  "summary": "Inosinic acid is a savoury flavour enhancer that barely tastes of anything alone. Its power is in combination: with glutamate it multiplies savoury intensity many times over, which is why Japanese dashi pairs kombu seaweed with dried bonito rather than using either by itself.",
  "derivation_summary": "Produced by bacterial fermentation, or by hydrolysing yeast RNA. It occurs naturally in meat and fish — bonito flakes are the classic source — and the commercial route is not usually declared.",
