coffee

Coffee is a beverage brewed from roasted coffee beans (seeds of the genus Coffea). Coffee is one of the most popular beverages in human society and an important cash crop. It is the second-highest futures trading volume in the world (the highest is oil).

Coffee is generally divided into two types: Arabica, which is highly regarded, and Robusta, which has coarser grains, lower acidity and stronger bitterness. Once the coffee is ripe, it will go through the process of picking, processing and roasting. The caffeine in coffee has a stimulating effect on the human body. Coffee is one of the most popular beverages in the world. It can be made in many ways, such as espresso, cappuccino, latte, etc., usually as a hot drink, but also as a cold drink. Before drinking, you can calculate the estimated caffeine intake to reach the standard of moderate intake. Most studies suggest that moderate coffee consumption is beneficial, even beneficial to healthy adults.

Main Ingredients

Sucrose: During the roasting process, part of it will be thermally hydrolyzed into formic acid, acetic acid, lactic acid, and glycolic acid. Therefore, the higher the sugar content of the green beans, the more sour they will be during shallow roasting, which can increase the complexity of the coffee aroma; part of it will undergo caramelization reaction during the process and become caramel, which can increase the flavor of the coffee.

Caffeine: Slightly bitter, with a melting point of 237°C, the caffeine in roasted coffee beans is almost completely preserved and will be incorporated into the cup during extraction. The main function of caffeine is to stimulate the central nervous system, heart and respiratory system. A moderate amount of caffeine can also reduce muscle fatigue and promote the secretion of digestive juices. Because it promotes kidney function and has a diuretic effect, it helps the body excrete excess sodium ions. However, excessive intake can lead to caffeine poisoning.

Chlorogenic acid: During light to medium roasting (first to middle second crack), about 50% of chlorogenic acid will be degraded into quinic acid (sour and astringent). Coffee is also the main source of chlorogenic acid for humans.

Fats: The most important of these are acidic fats and volatile fats.

Acidic fats: This means that the fat contains acid, the strength of which varies depending on the type of coffee.

Volatile fat: It is the main source of coffee aroma and emits about forty aromatic substances.

Protein: During the baking process, protein will participate in the Maillard reaction with sugars, thereby producing a complex aroma that is intoxicating.

Fiber: accounts for 70% of roasted coffee beans and cannot be extracted.

Minerals: Contains small amounts of lime, iron, phosphorus, sodium carbonate, etc.
