Abstract

The invention relates to a method for preparing aroma rapeseed oil by adopting a micro-channel reactor. The method comprises the following steps: step one, pumping a rapeseed enzymatic hydrolysis solution and an enzyme solution into the micro-channel reactor, mixing in a first mixing module and then entering into a reaction module to carry out enzymatic hydrolysis; step two, carrying out high-temperature enzymatic activity passivation, and ending the enzymatic hydrolysis; step three, sufficiently mixing a reaction system with reducing sugar and rapeseed oil so as to obtain a mixed reaction system; step four, the mixed reaction system entering into a second high temperature module, quickly raising the temperature to a technological requirement temperature, and carrying out a Maillard heat reaction; and step five, the reaction system flowing to a low temperature module, and flowing out of the micro-channel reactor to obtain a rapeseed oil crude product. According to the method, the enzymatic hydrolysis process can be accurately controlled, the heat reaction temperature and aftertreatment temperature can be quickly and accurately controlled; and by using an unamplifying effect of the micro-channel reactor, the method is easy for upgrading amplification, 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 rapeseed oil in a microchannel reactor. Background technique [0002] Rapeseed oil is one of the main edible oils in my country. It is rich in unsaturated fatty acids and has high nutritional value. Rapeseed is the most important oil crop in China, mainly produced in the Yangtze River Basin, southwest, northwest and other regions. China's rapeseed planting area and total output ranks first in the world, accounting for about 30% of the world's rapeseed planting area and total output [Dong Jiabao, Zhang Changgui, Wang Zhenxu. Research and Application of Edible Rapeseed Protein [J]. Grain and Oil, 2005, (12 ): 11-13]. [0003] The aroma substances of strong-flavor rapeseed oil are mainly produced by the Maillard reaction of amino acids and reducing sugars in rapeseed during the heating process, mainly including some aldo-ketoacids, sulfur-c...
