The structure name of each part of coffee bean

The coffee fruit is wrapped in a hard outer skin (cut skin), the inner layer is gelatinous pulp (pulp), and then the inner layer is endocarp (parchament), and the inside is tightly wrapped in the seed called silver skin, and the inside is wrapped in green seeds, that is, coffee beans.

There are usually two pairs of seeds, each hemispherical, with a plane opposite to each other, forming an ellipsoidal bean called flat bean, and about 5% of the seeds are single ellipsoidal, and this bean is called pea berry. Due to the scarcity of round beans, they are often made into brand-name products with high prices. There is also a sunken groove in the middle of the seed, called center cut, which is also covered with silver skin.

The Robosta coffee tree, which originated in the Congo in Africa, accounts for about 20% of the world's production. 30%. Robesta coffee tree is suitable for planting in the lowlands below 500 meters above sea level, has strong adaptability to the environment, can resist bad climate, resist diseases and insect pests, and does not need much manual care during soil preparation, weeding and pruning, and can be allowed to grow in the wild. It is a kind of coffee tree that is easy to cultivate. But its flavor is more bitter than Arabica, and its quality is much lower, so it is mostly used to make instant coffee. Because it is made in Africa, most Africans drink Robosta coffee. The Liberian coffee tree is produced in Liberia in Africa, and its cultivation history is shorter than that of the other two coffee trees, so the planting is limited to a few places such as Liberia, Surinam and Gaiana. As a result, the output accounts for less than 5% of the world's output. Liberian coffee trees are suitable for planting lowlands, and the coffee beans produced are very fragrant and bitter. Arabica Arabica robusta Robusta is usually grown in the mountains at higher elevations, usually in the lower tropics.
