Method for preparing strong-fragrance peanut oil through microchannel reactor

Abstract

The invention relates to a method for preparing strong-fragrance peanut oil through a microchannel reactor. The method comprises the following steps of step I, pumping peanut enzymolysis reaction fluid and an enzyme solution into the microchannel reactor, performing mixing in a first mixing module to obtain a mixture, enabling the mixture to enter a reaction module, and performing an enzymolysis reaction; step II, performing high-temperature enzyme activity inactivation, and ending the enzymolysis reaction; step III, thoroughly mixing a reaction system with reducing sugar and peanut oil so as to obtain a mixed reaction system; step IV, enabling the mixed reaction system to enter a second high-temperature module, rapidly raising the temperature to reach the temperature required by a technology, and performing a Maillard reaction; and step V, enabling the reaction system to flow across a low-temperature module and flow out of the microchannel reactor so as to obtain crude products of the strong-fragrance peanut oil. Through the adoption of the method disclosed by the invention, the enzymolysis process can be accurately controlled, and the thermal reaction temperature and the post-treatment temperature can be quickly and accurately controlled; and through the usage of the microchannel reactor, amplification effects are not generated, upgrading and amplification are easy, and seamless amplification from research and development to production can be realized.

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...
