1. Flexible non-airtight packaging: this is the most economical packaging. It is usually adopted by local small bakeries because they can guarantee rapid supply. Coffee beans can be consumed in time. Coffee beans packaged in this way can only be stored for a short time. 2, air-tight packaging: after loading the coffee, vacuum and seal it. Due to the formation of carbon dioxide in the baking process, this package can only be packaged after the coffee is left for a period of time to Degas, so there is a storage interval of several days. Coffee beans are kept longer than coffee powder. Since it does not need to be separated from air during storage, the cost is low. Coffee packed in this way should be used up within 10 weeks. 3, one-way exhaust valve packaging: After baking, the coffee is placed in a special one-way exhaust valve. This exhaust valve allows gas to go out, but cannot come in. There is no need for a separate storage phase, but there is a slight loss of fragrance due to the deflation process. It avoids the formation of corrupt taste, but it cannot prevent the loss of aroma. 4. Pressurized packaging: this is the most expensive way, but it can keep coffee for two years. After baking for a few minutes, the coffee can be vacuum packed. After adding some inert gas, keep the proper pressure in the package. The coffee beans are preserved under pressure to make the fragrance flow on the fat, thus improving the aroma of the beverage.
