Abstract

The invention belongs to the technical field of the extraction of vegetable fat. An extraction method of fruit-flavored rapeseed oil is characterized by comprising the following steps of 1), screening, cleaning and removing rapeseed impurity; 2), hulling and separating the rapeseed by adopting an automatic huller, so as to obtain a rapeseed kernel; 3), crushing and sieving the rapeseed kernel, soas to obtain hulled rapeseed meal; 4), crushing and sieving a freeze-dried fruit slice, so as to obtain lyophilized fruit meal; 5), uniformly mixing the hulled rapeseed meal with the lyophilized fruitmeal, extracting fat by adopting supercritical carbon dioxide, so as to obtain crude oil; 6), carrying out centrifugal separation on the crude oil, so as to subsequently obtain the fruit-flavored rapeseed oil. The method is simple in process flow, high in abstraction efficiency, environment-friendly and safe and the obtained fat is pure in fruit flavor and good in oxidation stability.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil extraction, and in particular relates to a method for extracting fruit-flavored rapeseed oil. Background technique [0002] At present, in the seasoning market for salads and other foods, there are seasonings that combine edible oil and various spices, but most of them are directly blended with edible flavors and spices, and freeze-drying may be shoddy. , it is necessary to use a safe and efficient method to extract oil and retain good flavor. Grease is a good flavor-carrying agent. Using the principle of "original taste", rapeseed powder and fruit powder can be compounded on the flavor raw materials, and then the oil and fruit flavor and aroma can be extracted simultaneously through supercritical carbon dioxide extraction to produce The flavored oil is green, safe and stable. Contents of the invention [0003] The purpose of the present invention is to provide a method for extracting fr...
