Processing Methods
Mucilage
The sticky, sugar-rich layer of pectin and simple sugars surrounding the coffee seed beneath the fruit skin. Mucilage composition and its management during processing profoundly influence the final cup flavor.
詳細分析
Mucilage is 80-90% water with the remainder being pectin, reducing sugars, and organic acids. During fermentation, microbes metabolize these sugars into alcohols, esters, and acids that either enhance or damage cup quality depending on control. In honey processing, the percentage of mucilage left on the bean determines the honey color designation. Mechanical mucilage removers (demucilagers) can strip 60-100% of the layer for washed processing without water fermentation.
