What Are Coffee Beans? The coffee beans you use to make coffee are actually seeds of a berry called the coffee cherry. The coffee plant is perennial, meaning that it will grow every year. Coffee beans are high in concentrations of certain compounds, such as caffeine, and should be consumed in moderation. Find out more about this popular seed. Origin Coffee is a brewed beverage made from the seeds that have been roasted (beans) of the coffee plant. The beans are among the most popular and lucrative international commodities. The coffee plants are evergreen, woody shrubs that thrive in tropical climates. The Bean Belt includes the areas that surround the Tropic of Cancer, and the Tropic of Capricorn. The most popular legend of coffee's origin starts with the goat herder Kaldi in Ethiopia. He noticed that his herd became especially active after eating the bright red berries of some coffee plants. Kaldi shared his discovery with the abbot of a nearby monastery, who made a drink out of the berries. From there, the energy-boosting effect of the berries grew. The coffee beans we have today come from two main varieties of the Coffea plant: Arabica and Robusta. The latter is found mostly in Africa and Indonesia and is usually less expensive than arabica. There are also smaller varieties that are a mixture of arabica & robusta. These beans are referred to as peaberries and are more flavorful than regular beans. During roasting, beans could lose their moisture, which can cause them to become stale or bitter. To avoid this, it is important to use only fresh, top quality beans for your coffee. Flavor The four components of flavor — acidity, bitterness, sweetness, and saltiness -are influenced by variety of beans, the climate, and the method of processing. The amount of these components can create a wide range of flavor profiles that range from fruity and sweet to nutty, or even smoky. When coffee beans are heated, they react with the amino acids contained in their seeds to form hundreds of unique aromatic compounds that affect the flavor profile of the coffee. This reaction is referred to as the Maillard Reaction, and it occurs in nearly all cooking. The result is that the smell of roasted coffee reflects those substances. While the Maillard Reaction affects the overall flavor of the roast, nonvolatile as well as volatile compounds are also a part of the flavor of a coffee. The taste of a unroasted or green bean may be earthy, floral, fruity, or chocolatey. Bitterness is often linked to roasts with a full body that contain more caffeine. However, coffeee beans could also be caused by improper preparation or storage. Flavored coffee beans are coated with flavor oils to help preserve the beans while adding an aroma and flavor. These flavored oils are a combination of natural and chemical flavors that can include everything from vanilla to cinnamon to chocolate. The flavors are bound to the beans by a chemical compound called polyphenol. Health Benefits Coffee beans contain a vast range of nutrients that boost health like magnesium, potassium, and B vitamins. They're also a good source of antioxidants, which help to prevent oxidative stress (which can cause chronic illnesses like cancer and atherosclerosis). The antioxidant chlorogenic acid found in coffee beans is especially effective against obesity-related illnesses like diabetes and high cholesterol levels. Coffee is a natural energy booster that helps people feel more alert. Caffeine stimulates neurochemicals, which enhances alertness, memory, and cognitive function. It also helps control blood sugar levels. Drinking moderate amounts of coffee has been shown to reduce the risk of Parkinson’s disease and dementia. It can also improve mood, satisfaction and energy levels, as well as concentration. Anti-ageing: The antioxidants (including caffeine and the chlorogenic acids) in coffee serve as a natural moisturizer for the skin, increasing cell turnover to reduce wrinkles and fine lines. They also provide UV-protection which block light and prevent sun-induced damage to the skin. Anti-depressant: Coffee beans can be used as an antidepressant that boosts serotonin and dopamine in the brain to increase the amount of happy hormones. It also helps relieve pain and inflammation by acting as a natural analgesic while improving the effectiveness of painkillers. Cafestol and Kahweol are diterpene esters compounds that have lipolytic qualities. They help reduce cellulite. Caffeine Coffee is one of the most popular drinks in the world and it has become an integral part of many morning routines. Coffee beans are actually seeds of a plant called the coffee plant, also known as the coffee cherry. they contain the natural stimulant, caffeine. The amount of caffeine in coffee is contingent on the method of roasting or prepared, as well as the method of brewing it. However, there are some fundamental rules regarding the amount of caffeine found in each coffee bean that will allow you to make informed choices when selecting your joe. The average coffee bean contains about 2 milligrams of caffeine, however the exact amount can vary depending on the bean's size and the degree of roasting it has been. There is a common misconception that darker roasted beans have more caffeine than lighter roasted ones, but this is not the case. A dark roast coffee bean will have less caffeine than light roasts due its lower density, however the total amount of caffeine will be the same. A typical cup of brewed coffee contains about 95 milligrams of caffeine within it, but the daily limit for consumption is 400 milligrams. If you're not sensitive to caffeine staying within this limit isn't likely to cause any adverse consequences. For those who aren't sensitive to caffeine may enjoy their coffee, however it's essential to be aware of the amount of caffeine you're ingesting and avoid excessive consumption.
