Coffee bean
Coffee Bean
A Coffee Bean is the seed of the coffee plant, and the source for coffee. It is the pit inside the red or purple fruit often referred to as a cherry. Even though they are seeds, they are referred to as 'beans' because of their resemblance to true beans.
Pronunciation
/kɒfi biːn/
Etymology
The term "coffee bean" is derived from the Dutch "koffieboon", which in turn was borrowed from the Ottoman Turkish "kahve". The Turkish word was borrowed from the Arabic "qahwah".
Description
The two most economically important varieties of coffee plant are the Arabica and the Robusta; ~60% of the coffee produced worldwide is Arabica and ~40% is Robusta. Arabica beans consist of 0.8–1.4% caffeine and Robusta beans consist of 1.7–4% caffeine. As coffee is one of the world's most widely consumed beverages, coffee beans are a major cash crop and an important export product, counting for over 50% of some developing nations' foreign exchange earnings.
Processing
Coffee beans are typically processed by either the wet process or the dry process. The wet process is used to remove the pulp and mucilage, while the dry process involves drying the beans in the sun. After processing, the beans are roasted to varying degrees, depending on the desired flavor. They are then ground and brewed to create coffee.
Health Effects
Coffee beans contain a number of compounds which can have an effect on the human body, including caffeine, antioxidants, and diterpenes. These can have both positive and negative health effects.
