Introduction,ovides employment for some twenty million people. Its gradual spread across the world, both as a crop and as a beverage, has been remarkable. The coffee tree is indigenous to Ethiopia but the early history of its cultivation and the use of coffee as a beverage, as we know it, is centred on Arabia. IMeasured 发表于 2025-3-24 08:53:33
Water and Mineral Contents,in exported green, whilst roasted coffee may contain up to 5%(w/w). Instant coffee contains up to 4 or 5%(w/w) as sold, though during processing liquid extracts may contain up to 50% or more. Water present at low levels is often referred to as moisture, the level of which plays an important part inFelicitous 发表于 2025-3-24 10:57:50

Nitrogenous Components,ecause the green coffee bean contains a wide range of different chemical compounds, but rather that these compounds react and interact at all stages of coffee processing to produce a final product (a cup of coffee) with an even greater diversity and complexity of structures.

Chlorogenic Acids,lly known as chlorogenic acids (CGA). Possibly the first report to describe these substances is attributable to Robiquet and Boutron.. These workers, while searching for physiologically active substances in coffee, isolated from green coffee beans an acidic substance which gave a green pigment with同来核对 发表于 2025-3-25 02:56:14
