Chocolate field glossary

Precursor

A compound that can be transformed into later aroma or flavor-active compounds, especially during roasting.

Post-harvest · working definition

Use the word
with precision.

Why it matters
It explains why a dried bean may not smell like finished chocolate even though it contains the building blocks for later aroma.
Common confusion
A precursor is not already the final flavor compound; heat and process conditions determine what it becomes.
Practical example
Amino compounds and reducing sugars formed or freed during post-harvest work can participate in Maillard reactions during roasting.
