Characteristics of capsule Coffee
Unique flavor
During the roasting process of coffee beans, the coffee oil adsorbs the volatile aroma components on the powder in gaseous form.
The ordinary brewing method can not dissolve most of the oil components of coffee, thus affecting its flavor and taste, but if the high-temperature water vapor passes through the coffee powder in a short time by high pressure, the coffee oil and the same insoluble colloid can be emulsified in water, and a layer of cream-like coffee foam (cream) can be formed on the upper layer of the liquid, so that the aromatic substances of coffee can be retained. Therefore, after brewing, the capsule coffee has the strong aroma and mellow thickness of Italian espresso (espresso).
The quality is lasting and stable.
Usually, the coffee powder after baking and grinding is stored in contact with the air, and the high quality flavor of coffee can only be preserved for 3 days, because the flavor substances of coffee are very sensitive to the surrounding environment (such as humidity, temperature, oxygen) and are prone to acidification, oxidation and other reactions, resulting in deterioration of its quality. For example, the aromatic aldehydes themselves are easily oxidized, which will be accelerated by exposure to light; dimethyl sulfides are not only volatile, but also easily oxidized to unscented and non-volatile methyl sulfoxide and lose their fragrance.
The capsule coffee quickly seals the roasted and ground coffee powder in a dark, dry and inert gas (nitrogen) capsule, which can prevent the oxidation, acidification and volatilization of aromatic substances of the coffee powder, thus retaining the original flavor of the coffee for a long time. However, this quality cannot be preserved forever. at present, the shelf life of encapsulated coffee on the market is usually only 12 to 18 months.
In addition, the capsule coffee is produced through the assembly line to achieve standardization and avoid errors caused by manual operation, thus ensuring the stability of the quality of each cup of coffee to a large extent.
Easy to brew and easy to carry
The method of brewing capsule coffee is very simple and can be achieved through a capsule coffee machine. When brewing coffee, just put the capsule in the corresponding position of the coffee machine, press the switch and wait for about 1 min, completely omitting a series of operations needed by the ordinary coffee machine to brew coffee, such as grinding, loading powder, pressing powder, cleaning coffee grounds, etc., while ensuring the original flavor of coffee, it greatly reduces the brewing time of coffee. Some coffee machines can even automatically recycle the used capsule shell, which is convenient and easy.
