Abstract

The invention relates to a method for preparing strong-flavored peanut oil by using a microchannel reactor. The following steps are performed: Step 1: pump the peanut enzymatic hydrolysis reaction solution and enzyme solution into the microchannel reactor, mix in the first mixing module and then enter the reaction module Carry out enzymatic hydrolysis reaction; step 2, high temperature inactivation of enzyme activity, terminate the enzymolysis reaction; step 3, fully mix the reaction system with reducing sugar and peanut oil to obtain a mixed reaction system; step 4, the mixed reaction system enters the second high temperature module, quickly The temperature is raised to the temperature required by the process, and the Maillard thermal reaction is carried out; Step 5, the reaction system flows through the low-temperature module, and flows out of the microchannel reactor to obtain the crude product of Luzhou-flavored peanut oil. The invention can accurately control the enzymatic hydrolysis process, and can quickly and accurately control the thermal reaction temperature and post-treatment temperature; there is no amplification effect by using a microchannel reactor, and it is easy to upgrade and enlarge, and can realize 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 fragrant peanut oil in a microchannel reactor. Background technique [0002] Peanut oil is a traditional edible oil in China, and the flavor of fragrant peanut oil is the most important edible quality of peanut oil. [0003] At present, the processing of Luzhou-flavored peanut oil adopts traditional production technology: roasting and frying peanuts at high temperature to make oil or rolling peanuts first and then steaming and frying at high temperature to make oil. During the whole process, roasting is the key aroma production process. The flavor substances of peanut oil are mainly formed by the Maillard reaction of reducing sugars and amino acids in peanuts during the roasting and heating process, mainly including nitrogen-containing compounds represented by pyrazines. Cyclic compounds, caramelization reaction products and oil oxidation products...
