Abstract

The invention discloses a method for simultaneously producing pressed rapeseed oil and leaching flavored rapeseed oil, comprising the following steps: 1) rapeseed pretreatment; 2) flaking: conductingflaking on rapeseeds; 3) cooking: putting the rapeseeds in a cooking pot and conducting cooking for 120-140 DEG C for 30-40 min; 4) pressing: pressing a mixed material for 3-5 min under a pressure of70-90 atmospheres to get pressed crude oil and rapeseed cakes; 5) leaching: taking the rapeseed cakes, adding soybean meal for mixing, and conducting leaching with 6# solvent oil to obtain leaching crude oil; 6) rapeseed oil refining: refining the pressed crude oil to obtain the pressed rapeseed oil; and 7) refining of flavored rapeseed oil: refining the leaching crude oil to obtain the flavored rapeseed oil. The method for simultaneously producing pressed rapeseed oil and leaching flavored rapeseed oil of the invention produces the pressed rapeseed oil and the leaching flavored rapeseed oil at the same time through once pressing, the pressed rapeseed oil meets the national standard of fourth grade oil, and the flavored rapeseed oil has rich nutrients and unique flavor, and meets food standards and requirements.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of rapeseed oil, in particular to a method for simultaneously producing pressed rapeseed oil and extracting flavor rapeseed oil. Background technique [0002] There are many existing rapeseed oil processing methods. For example, in Chinese patent CN 106929140A, a flavor rapeseed oil processing method is disclosed, which includes the following steps: ①Cleaning and flaking: screening, magnetic separation and stone removal of rapeseed , the impurity index after cleaning is less than 0.4%, and the rapeseed is flaked; ②Fried seeds: uniformly mix the rapeseed with grape seeds, melon seeds, pine nuts, and Humulus to obtain a mixed material, and then mix the mixture The temperature of the material is cooled to -3°C, and then within 10 minutes, the temperature is rapidly raised to 103-105°C, kept for 8-10 minutes, and then a 60Co radiation device is used, the activity of the cobalt source is 3....
