The carrot belongs to the root vegetables of umbelliferae, has delicious taste and good nutritional value, and is especially rich in carotene. The carotene has high nutrient content, wherein the beta-carotene can be converted into vitamin A in a human body, and the health condition of eyes and skin is improved; simultaneously, the health-care food also has the effects of improving the immunity of human bodies and preventing chronic diseases, such as diabetes, obesity, partial cancers and the like; and has remarkable effect of nourishing and protecting the liver. Because the structural characteristics of carotene are sensitive to light, heat and oxygen, and the extraction of carotene is limited by various factors, the common carotene extraction process mainly depends on an organic solvent extraction method, although the method has the advantage of high extraction efficiency, the carotene extracted by the method still needs to be processed again to be prepared into food, the process is complex, and certain organic solvent residues exist. Therefore, the development method is relatively simple, and the method can be directly prepared into the product rich in carotene and is an industrially feasible method.
CN201510891273.4 discloses a method for fortifying soybean oil with carotene, which is to add extracted carotene, phospholipid, vitamin E, etc. into soybean oil to fortify the nutrition of soybean oil.
CN201110250219.3 discloses a process for preparing carrot volatile oil. The method adopts the processes of drying, crushing, distilling, separating and the like to separate the volatile oil of the carrots, and has the disadvantages of complex process, high operation temperature and serious carotene loss.

(4) and (3) circulating treatment: adding the material liquid subjected to ultrasonic treatment in the step (3) into a colloid mill, and continuing to perform grinding-ultrasonic circulation treatment in the steps (2) - (3), wherein the circulation times are 2-3 times;
(5) and (3) centrifugal treatment: centrifuging the circularly treated feed liquid, collecting the edible oil rich in carotene at the upper part, and removing carrot residue and water at the lower part;
(6) and (3) reduced pressure distillation: distilling the edible oil sample obtained in the step (5) at 35-40 ℃ under reduced pressure, and recovering ethanol;
(7) freezing treatment: freezing the edible oil sample obtained in the step (6) at-10 to-15 ℃ overnight;
(8) freezing and centrifuging: and (4) centrifugally separating the semi-solidified crude oil obtained in the step (7) at-4 to-6 ℃ to remove ice crystals, and collecting the upper edible oil part to obtain the edible oil rich in carotene.
The edible oil is common edible oil such as soybean oil, corn oil, rapeseed oil, sunflower seed oil, etc.
The carrot granules in the step (1) are 2 x 2 mm-4 x 4 mm.
The carotenoid content of the edible oil rich in carotene produced by the method is more than or equal to 150mg/L (when carrot granules are mixed with 4 times of edible oil).
Compared with the prior art, the invention has the following advantages:
(1) the invention directly takes the edible oil and the carrots as raw materials to directly prepare the carrot oil product, thereby avoiding the traditional extraction and addition processes;
