Ultrahigh-pressure cold-extracted coffee and preparation method thereof

Abstract

The invention discloses ultrahigh-pressure cold-extracted coffee and a preparation method thereof. The preparation method comprises the following steps: mixing coffee powder and water, performing sealing, and performing ultrahigh-pressure extraction to obtain an extract; and filtering and perfusing the extract, and performing sterilization under ultrahigh pressure so as to obtain the finished product. The ultrahigh pressure extraction mode improves the production efficiency and remarkably shortens the time. Compared with traditional cold-extracted coffee preparation processes, the method of the ultrahigh-pressure cold-extracted coffee innovatively uses an ultrahigh pressure technology twice. The first-time ultrahigh-pressure extraction obtains the coffee containing the required caffeine concentration by using cold water at a temperature of 4 DEG C in a short time, so that the preparation time is shortened, the production efficiency is improved, the extraction times are reduced, and theproduction convenience is improved. The second-time ultrahigh-pressure sterilization prolongs the shelf life of the product on the basis of ensuring the safety of the product. Meanwhile, by adoptingthe ultrahigh-pressure sterilization instead of adding the preservative in the traditional production, the method is favorable for meeting the pursuit of consumers on natural foods, and is favorable for meeting the approval of the society on the clean labels.
