What Are Coffee Beans? The coffee beans you use to brew are actually the seeds of the fruit called a coffee cherry. The coffee plant is perennial plant, which means that it returns every year. Coffee beans contain high concentrations of certain compounds – such as caffeine, and therefore should be consumed in moderation. Find out more about this well-known seed. Origin The roasted seeds of the coffee plant are used to make the coffee beverage that is brewed. The beans are a sought-after and profitable international commodity. Coffee plants are woody, evergreen shrubs that grow in the tropical regions. The majority of the world's beans is grown in the Bean Belt, which includes the regions around the Tropic of Cancer and the Tropic of Capricorn. The most popular story about the origin of coffee began in Ethiopia with a goatherder named Kaldi. He noticed that his animals became extremely energetic after eating the bright red berries of some coffee plants. Kaldi shared his discovery with the abbot of a nearby monastery, who came up with a drink made from the berries. From there, the energizing effect of the berries spread. Coffee beans today come from two major varieties of the Coffea plant: Arabica and Robusta. Robusta is mostly in Africa and Indonesia and is generally less expensive than arabica. In addition to the major varieties, there are smaller, specialty beans that are a mix of robusta and arabica. These beans are called peaberries and are much more flavorful than standard beans. When roasting, beans may lose moisture, which could result in them becoming bitter or stale. It is crucial to make use of fresh, high-quality beans for your coffee. coffee beans unroasted , climate and processing method can influence the four elements of taste: acidity and bitterness along with sweetness and saltiness. These elements can be used in a variety ways to create different flavor profiles, from sweet and fruity to nutty and even smoky. When coffee beans are heated they react with amino acids in their seeds, forming hundreds of aromatic compounds that influence their flavor profile. This process is called the Maillard Reaction and it is the same chemical reaction that happens in virtually every cooking. The result is that the smell of roasted coffee is a reflection of these chemical compounds. The Maillard Reaction is responsible for the overall flavor, however volatile and nonvolatile components also contribute to the taste of coffee. Green beans, whether unroasted or not, can possess a flavor that is earthy, floral or fruity. Bitterness is often associated with roasts with a full body that contain more caffeine. However, it could also be caused by improper brewing or storage. Flavored coffee beans are coated with flavor oils to help preserve the beans while adding the flavor and aroma. These oils that are flavored can be composed of chemicals as well as natural flavors, such as cinnamon, vanilla and chocolate. The flavors bond to beans by using an extremely chemical compound known as polyphenol. Health Benefits Coffee beans are packed with a variety of nutrients that are good for health, such as magnesium, potassium and B vitamins. They also provide a valuable source of antioxidants, which help prevent the oxidative stresses (which can lead to chronic diseases like atherosclerosis and cancer). The antioxidant chlorogenic acids in coffee beans are especially beneficial against obesity-related diseases like diabetes or high cholesterol levels. Coffee is also a natural energy booster which makes people feel more energetic and alert. The caffeine it contains stimulates neurochemicals in the brain, improves concentration and vigilance, enhances cognitive function and helps control blood sugar levels within the body. Drinking moderate amounts of coffee has been proven to decrease the risk of developing Parkinson's disease and dementia. It also boosts happiness, mood energy, concentration, and satisfaction. Anti-aging: The antioxidants (including caffeine and the chlorogenic acids) in coffee act as natural moisturizers for the skin, increasing cell turnover, which reduces wrinkles and fine lines. They also possess UV-protection capabilities blocking light and preventing sun-induced damage to the skin. Anti-depressant: Coffee beans can be used as an antidepressant by increasing serotonin and dopamine in the brain, which increases the amount of happy hormones. It can also relieve inflammation and pain, acting as a natural painkiller and improving the effectiveness of prescription painkillers. Coffee also has cafestol and kahweol. These are diterpene esters with lipolytic properties in the adipose tissues, aiding in fighting cellulite. Caffeine Coffee is a popular drink across the globe. It is now an integral part of most morning routines. Coffee beans are the seeds of the coffee plant, or the coffee cherry. They are a source of caffeine, which is a natural stimulant. The amount of caffeine in coffee can differ based on how it is roasted or prepared, as well as the method of brewing it. There are a few rules that can help you select the right coffee. The average coffee bean contains approximately 2 milligrams per bean. However the exact amount will differ based on the size and the degree to which it has been roast. There is a widespread belief that dark roasts have more caffeine than light roast ones however this isn't the reality. A dark roast coffee bean will contain less caffeine in it than lighter roasts due to its lower density, but the amount of caffeine will be similar. The daily limit recommended for caffeine is 400 milligrams. A typical cup of coffee contains 95 milligrams. If you are not sensitive to caffeine staying within this limit should not have any negative consequences. Caffeine is not harmful to those who aren't. However it is essential to keep track of how much caffeine you consume and to avoid overdoing.
