Embodiment 1

[0054] The present embodiment provides a kind of processing method and rapeseed oil of strengthening rapeseed oil flavor, and this method comprises the following steps:

[0055] Step 1: Selection of raw materials: select fresh rapeseed with full grains and no mildew as raw materials;

[0056] Step 2: crushing: crushing the rapeseed obtained in step 1 through a grinder and collecting the crushed rapeseed powder, wherein the crushing degree is 20-40 mesh;

[0057] Step 3: microwave treatment: microwave the rapeseed powder obtained in step 2, wherein the microwave power is 200W, and the microwave treatment time is 2 minutes;

[0058] Step 4: Dry steaming: dry-steam the rapeseed powder obtained by microwave treatment in step 3, collect the steam distilled during the dry steaming process, and obtain a condensate after the steam is condensed; wherein, dry steaming is to dry the microwave-treated rapeseed powder Put the seed powder into the distillation bottle separately for distill...

Embodiment 2

[0062] This example provides a processing method for enhancing the aroma of rapeseed oil and rapeseed oil. The difference between this example and Example 1 is that the microwave power in Step 3 is 300W, and other raw materials and experimental conditions are the same.

Embodiment 3

[0064] This example provides a processing method for enhancing the aroma of rapeseed oil and rapeseed oil. The difference between this example and Example 1 is that the microwave power in Step 3 is 400W, and other raw materials and experimental conditions are the same.

Abstract

The invention discloses a processing method for enhancing the aroma of rapeseed oil and rapeseed oil. In the method, the rapeseed oil is sequentially crushed, microwave-treated and dry-steamed to obtain a condensate, and the condensate is mixed with the finished oil and then statically prepared. Put layers, take the supernatant to obtain the fragrant rapeseed oil. In the present invention, the condensate with strong fragrance is obtained by dry steaming and pulverizing rapeseed powder, which is mixed with rapeseed oil, and the obtained rapeseed oil not only has strong flavor and clear color, but also simplifies the production and processing technology of strong fragrance rapeseed oil , to solve the problems of low oil yield and cumbersome production links in the traditional process, and reduce the loss of aroma substances in the refining process of aromatic rapeseed oil, save costs, shorten production time, and improve the economic benefits of aromatic rapeseed oil production.

Description

technical field [0001] The invention belongs to the field of preparation of strong-flavored rapeseed oil, and in particular relates to a processing method for enhancing the fragrance of rapeseed oil and rapeseed oil. Background technique [0002] The formation of the characteristic flavor of Luzhou-flavored rapeseed oil has a lot to do with the source of raw materials, pretreatment, roasting process and subsequent refining process, and the flavors produced are different due to different processing techniques and methods. Pressing is the traditional method of oil extraction, including hot pressing and cold pressing. Hot pressing is to press the rapeseed after the frying process to obtain strong flavor rapeseed oil. Some biologically active substances; cold pressing is directly pressed without high-temperature fried seeds, which retains the biologically active substances in rapeseed to a greater extent, but the obtained rapeseed oil has a weaker aroma and lower oil yield. An...
