Abstract

The present invention relates to a method of using a microchannel reactor to prepare coffee essence. The method comprises the following steps: step 1, a coffee bean enzymolysis reaction solution and an enzyme solution are pumped into the microchannel reactor, the materials are mixed in a first mixing module, and the mixture enters into a reaction module to be subjected to an enzymolysis reaction; step 2, an activity of enzymes is inactivated using a high temperature and the enzymolysis reaction is terminated; step 3, a reaction system is fully mixed with reducing sugar and refined oil to obtain a mixed reaction system; step 4, the mixed reaction system enters a second high temperature module, a temperature is rapidly increased to the temperature required by a technology, and a Maillard thermal reaction is conducted; and step 5, the reaction system flows through a low temperature module and flows out the microchannel reactor to obtain the coffee essence crude products. The method can accurately control the enzymolysis processes and can conduct the rapid and accurate control of the temperature of the thermal reaction and the temperature of a post-treatment. The microchannel reactor is free of amplification effects and easy to upgrade and amplify, and can realize the seamless amplification from research and development to production.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a method for preparing coffee essence in a microchannel reactor. Background technique [0002] The processing technology of coffee beans directly affects the flavor of coffee products. [0003] At present, the processing of coffee adopts the traditional production process: the coffee beans are roasted and roasted at high temperature to produce a strong flavor. In the whole process, roasting and roasting is the key aroma production process. The flavor substances of coffee are mainly composed of reducing sugar and amino acids in coffee beans. It is formed through the Maillard reaction during the roasting and heating process, mainly including nitrogen-containing heterocyclic compounds represented by pyrazine, caramelization reaction products, and oil oxidation products. However, the aroma production process of this traditional process is difficult to be accurately controll...
