illy coffee company brand culture illy coffee latest introduction

Illy coffee is very focused on the roasting process, in which the beans are placed in a large rotating cylinder. In the course of 12-15 minutes, the beans lose about 20% of their weight, but expand to 1.6 times their original volume. A series of physical and chemical reactions take place within coffee beans to create more than 1500 substances that are the source of espresso flavor and aroma. illy Coffee precisely controls every step of the roasting process and records in detail the characteristics of each batch, recipe, roasting time, temperature changes and final taste test results.

After the production and processing stages are complete, coffee must pass through the important final step of preservation and packaging; improper packaging will make all previous efforts useless. The proper inclusion must be able to preserve more than 1500 volatile substances rich in coffee aroma in coffee beans intact. Illy coffee in addition to purchasing, blending, baking and other aspects of care, there is a more important reason to make coffee aroma stronger, taste more mellow, is illy patented pressure packaging method. Francesco Illy found that after many experiments, the air in the container was removed, and then the inert gas (Inert Gas) after pressurization (1.3 bar) was injected. Observing the coffee cell tissue under the electron microscope, it was found that the coffee oil scattered scattered originally would be concentrated around the cell wall after pressurization, wrapping some aroma-rich and volatile chemicals in the cell, and isolating it from air contact for oxidation. As a result, coffee flavor and freshness can be preserved intact for up to three years. Through this technique, the precious aroma of the coffee beans is not lost. The higher air pressure in the container allows the aroma molecules in the coffee to be fixed in the coffee oil, and these aromas are released only when the coffee is used to extract espresso.

The inert gas pressurization method can ensure that the shelf life of coffee will far exceed the period of traditional vacuum packaging method or one-way valve packaging method; the shelf life can not only be extended, but also improve the taste. That's because volatile aromas are fixed in the oil in the coffee beans and cannot be released, making the aroma of coffee stronger. In the choice of packaging materials, illy also uses environmentally friendly materials. From the time of harvest to packaging, illy coffee beans undergo 114 inspections and tests in the hope of improving their quality. But the final judgment is still up to you.
