How does the coffee capsule produced and keep fresh?

May 14 , 2021

Coffee capsule is a coffee category first invented and produced by Nestlé, and it was once very popular. A set with only a few dozen pieces in a box is not cheap, and it must be used with a coffee capsule machine that is also not cheap. Despite this, the sales volume of coffee capsule has always been relatively good, so let’s briefly introduce it.


The production principle of coffee capsule

Coffee capsule is to seal by coffee capsule sealing machine and roasted coffee powder in a special capsule within 4 hours. (Currently aluminum nespresso coffee capsules is generally more environmentally friendly) Drinking needs to be put into a special coffee machine and extracted by standard procedures. Preservation instructions Put the standardized ground and roasted coffee powder into a capsule composed of a seal, filter membrane, heat-resistant container, etc., and immediately fill it with nitrogen and seal it.


Because it is quickly sealed in a light-proof, dry and inert gas-filled capsule, the loss of aromatic substances in the coffee powder is minimized, so the original flavor and taste of the coffee can basically be retained. Of course, this quality cannot be preserved forever. The shelf life of coffee capsule currently on the market is usually 12-18 months. coffee capsule features a unique flavor. During the roasting process, the coffee oil attaches the aroma components to the powder in a gaseous form. Ordinary brewing methods cannot dissolve most of the fat, so the flavor and taste are not good, but the coffee capsule uses high pressure to make high-temperature water vapor pass through the coffee powder in a short time, which can emulsify the fat in the water and form a layer. The foam of the cream preserves the aroma of the coffee. Stable quality The roasted and ground coffee powder is stored in contact with air, and the coffee loses a lot of high-quality flavor. The production process of coffee capsule can prevent coffee powder from oxidation, acidification and aroma volatilization. In addition, the production of coffee capsule on the assembly line is fully standardized, which basically guarantees the stability of the quality of each cup of coffee. Convenient and fast brewing. One coffee capsule machine can be used to make a cup of coffee. Put the capsule into the corresponding position of the coffee machine and press the switch, just wait for less than 1 minute. The operations of grinding, filling, pressing powder, and cleaning coffee grounds of ordinary coffee machines are completely omitted, which saves time!
