Abstract

The invention relates to a method for preparing rich-fragrance sesame seed oil by adopting a microchannel reactor. The method comprises the following steps: (1) pumping a sesame seed enzymolysis reaction solution and an enzyme solution into the microchannel reactor, carrying out mixing in a first mixing module, and then, subjecting the mixture to an enzymolysis reaction in a reaction module; (2) passivating enzyme activity by a high temperature to terminate the enzymolysis reaction; (3) thoroughly mixing the reaction system with reducing sugar and sesame seed oil, so as to obtain a mixed reaction system; (4) enabling the mixed reaction system to enter a second high-temperature module, rapidly heating the temperature of the mixed reaction system to a process required temperature, and carrying out a Maillard thermal reaction; and (5) enabling the reaction system to flow through a low-temperature module and flow out of the microchannel reactor, thereby obtaining a crude rich-fragrance sesame seed oil product. According to the method, an enzymolysis process can be accurately controlled, and a thermal reaction temperature and an aftertreatment temperature can be rapidly and accurately controlled; and by using the microchannel reactor, no scale effect is caused, upgrading scaling is facilitated, and seamless scaling from research and development to production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a method for preparing fragrant sesame oil in a microchannel reactor. Background technique [0002] Sesame oil is a traditional edible oil in China. The flavor of sesame oil is the most important edible quality of sesame oil. [0003] At present, the processing of Luzhou-flavored sesame oil adopts the traditional production technology: fry the sesame seeds at high temperature and press them to make oil; High-temperature steaming and pressing to make oil. During the whole process, roasting is the key aroma production process. The flavor substances of sesame oil are mainly formed by the Maillard reaction of reducing sugars and amino acids in sesame during the roasting and heating process, mainly including nitrogen-containing impurities represented by pyrazine. Cyclic compounds, caramelization reaction products and oil oxidation products, etc. However, the main purpose o...
