The Economic value of cultivated Coffee

Coffee is the second largest raw material product after petroleum in international trade and one of the largest tropical food raw materials in the world. Coffee is most commonly used as a beverage, and among the world's three major beverages, coffee consumption is the largest. At present, there are hundreds of kinds of foods made of coffee, which are favored by consumers because of their convenience and nutrition.

Because coffee contains starch, lipids, proteins, sugars, caffeine, aromatic substances and natural detoxifiers and other organic components, it has a wide range of uses in the food industry, such as coffee candy, coffee preserved fruit, coffee ice cream, coffee jelly, etc. In addition to being used as a staple beverage and a range of foods, caffeine is used in medicine as an anesthetic, stimulant, and cardiac stimulant. In recent years, the New York Blood Center in the United States has also extracted a substance called "cutting enzyme" from coffee beans, which can convert "B type" blood into "O type" and expand the new use of coffee. Coffee pulp can still be used for wine, vinegar, feed and fertilizer, and can also produce a sticky, non-flammable and impermeable glue. In addition, coffee flowers can extract high-grade spices, tannins in coffee fruits and organic acids obtained from fermentation of coffee residue can be made into tannins. In short, coffee has a wide range of uses in both food development and pharmaceutical supplies and industry.

Cultivated coffee has early income and high output value. A small amount of harvest can be obtained 2~3 years after planting, and the harvest period reaches 20~30 years. The average yield of dry beans per mu is 100~150 kg. The output value reached 2500~3750 yuan (calculated by 25 yuan per kilogram of dry beans). High yield reached more than 250 kg, and the output value was higher.

World coffee consumption is high, about three times that of cocoa and four times that of tea. According to statistics, in 1976, the total export volume of coffee in the world reached 3.65 million tons. In the 1970s, the total export volume of coffee in the world increased by 2.2% on average every year, reaching 4.1 million tons in 1980 and 5 million tons in 1990. At present, China's coffee production not only fails to meet the needs of the domestic people, but also fails to meet the requirements of some friendly countries to purchase Chinese-produced coffee. Therefore, the proper development of coffee production is of great significance to the implementation of the diversified management policy, the increase of economic benefits, the exchange of foreign exchange and the satisfaction of the needs of the people.
