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 reinforcing aroma of rapeseed oil and the rapeseed oil. The method includes the steps of sequentially conducting smashing, microwave treatment and dry-steaming on the rapeseed oil to obtain condensate, mixing the condensate with a finished oil product for standing and layering, and taking supernate to obtain the strong-aroma rapeseed oil. The strong-aroma condensate is obtained from dry-steamed and smashed rapeseed meal and then mixed with the rapeseed oil, the obtained rapeseed oil is strong in flavor and clear and bright in color and luster, the producing and processing process of the strong-aroma rapeseed oil is simplified, the problems that the oil yield is low and the production link is complicated in the traditional process are solved,the loss of aroma substances of the strong-aroma rapeseed oil in the refining process is reduced, cost is saved, the production time is shortened, and the production economic benefits of the strong-aroma rapeseed oil are improved.

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...
