Embodiment 1

[0031] a. Add 5kg corn oil and 10kg comfrey seed oil into the mixing tank I at the same time according to the mass ratio of 1:2, and fill it with nitrogen at 40°C to keep the pressure in the mixing tank I at 0.1MPa, and stir for 45min. Rotating speed is 40r / min, stand still, and drop to 25 ℃ by the internal cooling system temperature of mixing tank I;

[0032] b. Add 85kg corn oil to the mixing tank II, and add the mixed oil in the mixing tank I at the same time, so that the mass fractions of corn oil and comfrey seed oil are finally: 90% corn oil and 10% comfrey seed oil;

[0033] c. Under the condition of 30°C, fill the mixing tank II with nitrogen gas, keep the pressure inside the mixing tank II at 0.1MPa, stir for 120min at a speed of 40r / min, and let it stand still to obtain corn blended oil containing comfrey seed oil .

Abstract

The invention belongs to the technical field of edible blend oil, and particularly relates to a corn blend oil containing lithospermum seed oil and a preparation method thereof. The corn blend oil comprises the following components in percentage by weight: 85-95% of corn oil and 5-15% of lithospermum seed oil. The corn blend oil containing lithospermum seed oil solves the problems of unbalanced fatty acid composition and low linolenic acid content in the corn oil, enhances the nutritive value of the corn oil, and has higher nutritive value than the single corn oil. The preparation method is simple to operate, has the advantages of reasonable technique and low production cost, can easily implement industrialized production, and can satisfy the demands of mass consumers.

Description

technical field [0001] The invention belongs to the technical field of edible blending oil, and in particular relates to a corn blending oil containing comfrey seed oil and a preparation method thereof. Background technique [0002] Corn oil is a vegetable oil made from corn germ, mainly composed of unsaturated fatty acids. Among them, linoleic acid is an essential fatty acid for the human body, which is an integral part of human cells. It can be combined with cholesterol in the human body, showing fluidity and normal metabolism, and has the effect of preventing and treating cardiovascular diseases such as atherosclerosis. Sitosterol in corn oil has the effect of lowering cholesterol, is rich in vitamin E, has antioxidant effect, can prevent dry eye disease, night blindness, dermatitis, bronchiectasis and other functions, and has certain anticancer effect. Due to the characteristics of corn oil, but also because of its high nutritional value, good taste, and not easy to det...
