Coffee beans using cryopreservation method is the best recipe?

Coffee is a fresh food, as long as it comes into contact with the air, it is easy to oxidize, so it is common to buy good coffee beans, but because of a large amount of coffee, these beans will lose their original baking flavor during the shelf life. Therefore, it is wise to buy the right amount and finish the cooking within the expiration date. If possible, it is best to finish it within a week at a time.

However, if the coffee beans bought cannot be consumed in a short period of time, how can they be preserved in order not to lose their freshness? This must be known. Roasted coffee beans are stored at room temperature for about two weeks, but during this period, oxygen should not be allowed to enter as far as possible, so they must be packed in sealed cans.

If it must be preserved for more than two weeks, it is best to use freezing. As long as it is sealed and preserved, the quality will not change for two months after opening. If you want to use it, just take out the required quantity from the freezer, and even if it is taken out of the freezer, you can grind it immediately. If you buy ground coffee powder, please avoid using room temperature preservation, because even in a sealed container, the coffee powder will gradually lose its fragrance after four days.

At this time, the use of cryopreservation is the best prescription. Put the coffee powder in a sealed jar and freeze it. The taste and aroma can be preserved for about a month.
