Quality of coffee (Coffea arabica L.) seeds stored as dry cherry, with different moisture contents
Arabica coffee harvested in Ijaci, Minas Gerais, Brazil, was stored as dry cherry (without hulling) from August 1999 to January 2000. Moisture contents ranged from 10.28 percent to 16.25 percent. Some of the berries were partially dried before storage. Data are presented on changes in density, titratable acidity, phenolic compounds, polyphenoloxidase (catechol oxidase) activity, potassium leaching and sugars during storage. High moisture content did not affect bean quality. The intense bleaching previously reported in beans stored with high moisture contents was not observed. Partial drying reduced bean quality after storage.
