咖啡老化作用 Coffee Deterioration
咖啡老化作用 -咖啡豆會隨著時間慢慢老化，通常會有幾個現象，首先會緩慢的流失芳香化合物，芳香化合物是咖啡烘焙後自然產生的風味來源，具有高揮發性，所以咖啡豆放愈久、風味愈少。同時，咖啡會有氧化及受潮現象，會慢慢發展出不討喜的味道、帶有木頭味、喝起來平淡。
Coffee deterioration - Coffee beans will deteriorate slowly over time. There are usually several phenomena. First, they will slowly lose aromatic compounds. Aromatic compounds are the source of flavor naturally produced after coffee roasting and are highly volatile. The longer the time, the less flavor. At the same time, the coffee will be oxidized and dampened, and it will slowly develop an unpleasant, woody, bland taste.
