Description

Technical Field

[0001] The invention belongs to the technical field of edible oils and relates to a camellia oil compound composition with lipid-lowering function. Background Art

[0002] Edible oil is an important source of energy for the human body and is indispensable in daily life. In addition to being used as a cooking medium, it can also be used in food processing areas such as pastries, salads, sauces and baked goods.

[0003] Edible oils are mainly divided into two categories: vegetable oils and animal oils. Vegetable oils are usually squeezed from plant seeds or fruits, while animal oils come from animal fats, such as lard. Since animal oils are not easily absorbed by the human body, vegetable oils are becoming more and more popular. With the improvement of living standards, people's consumption concepts of edible oils have also changed greatly. The criteria for choosing edible oils are no longer based on meeting hygiene and safety standards, but more on the health of edible oils.

[0004] Common vegetable oils include soybean oil, rapeseed oil, peanut oil, sunflower oil, cottonseed oil, etc. Although these vegetable oils have their own advantages, they have a single nutritional composition and lack linolenic acid, an essential fatty acid for the human body. Excessive consumption can lead to weight gain, increased cholesterol and triglyceride levels in the blood, and increased risks of cardiovascular and cerebrovascular diseases. Summary of the invention

[0005] In view of this, the present invention provides a camellia oil compound composition with lipid-lowering function. The camellia oil compound composition provided by the present invention is rich in nutrients and has a good lipid-lowering effect.

[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0007] A camellia oil compound composition with lipid-lowering function comprises the following components in parts by weight: 1 to 5 parts of camellia oil, 1 to 5 parts of linseed oil and 1 to 5 parts of perilla oil.

[0008] Preferably, the camellia oil compound composition with lipid-lowering function comprises the following components in parts by weight: 1 part of camellia oil, 1 part of linseed oil, and 1 part of perilla oil.

[0009] Preferably, the camellia oil compound composition with lipid-lowering function further comprises 0.1 to 0.5 parts of antioxidant.

[0010] Preferably, the antioxidant comprises one or more of ascorbyl palmitate, vitamin E, butylated hydroxyanisole, tert-butylhydroquinone or tocopherol.

[0011] The present invention also provides a method for preparing the camellia oil compound composition with lipid-lowering function described in the above scheme, comprising the following steps:

[0012] The camellia oil, linseed oil and perilla oil are mixed to obtain the camellia oil compound composition with lipid-lowering function.

[0013] Preferably, when the camellia oil compound composition with lipid-lowering function further comprises an antioxidant, the antioxidant is also added during the mixing.

[0014] Preferably, the method for preparing linseed oil comprises the following steps: cold-pressing linseed and then filtering, standing to clarify, degumming, deacidifying, decolorizing and deodorizing in sequence to obtain linseed oil.

[0015] Preferably, the flax seeds are pretreated before cold pressing; the pretreatment method is ultrasonic treatment and / or microwave treatment; the frequency of the ultrasonic treatment is 10 to 30 kHz and the time is 1 to 10 minutes; the power of the microwave treatment is 600 to 800 W and the time is 1 to 10 minutes.

[0016] Preferably, the preparation method of perilla oil comprises the following steps: pre-treating perilla seeds and then pressing them, filtering and standing to clarify, to obtain the perilla oil; the pre-treatment method is microwave treatment; the microwave treatment power is 600 to 800 W, and the time is 1 to 10 minutes.

[0017] The present invention also provides a food or health product with lipid-lowering function, the components of which include the camellia oil compound composition with lipid-lowering function described in the above scheme or the camellia oil compound composition with lipid-lowering function prepared by the preparation method described in the above scheme.

[0018] The invention provides a camellia oil compound composition with lipid-lowering function, comprising the following components in parts by weight: 1 to 5 parts of camellia oil, 1 to 5 parts of linseed oil, and 1 to 5 parts of perilla oil. Camellia oil is rich in monounsaturated fatty acids, wherein the oleic acid content is very high, generally between 74% and 87%. Oleic acid can reduce the levels of total cholesterol and low-density lipoprotein cholesterol in the blood, increase the level of high-density lipoprotein cholesterol, help maintain the function of vascular endothelial cells, and reduce the deposition of lipids in the blood vessel wall. Perilla oil contains a large amount of α-linolenic acid, the content of which is usually around 50% to 60%. α-linolenic acid belongs to the ω-3 series of polyunsaturated fatty acids, which can be converted into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the body through a series of enzymatic reactions. EPA and DHA have the effects of reducing triglycerides, reducing blood viscosity, and reducing the risk of atherosclerosis. Moreover, α-linolenic acid itself can also regulate blood lipid metabolism and inhibit the synthesis of triglycerides in the liver; flaxseed oil is also a good source of α-linolenic acid, wherein the α-linolenic acid content is generally 50% to 60%, and its mechanism of action is similar to that of perilla oil. The active substances produced after metabolism in the body can reduce the levels of triglycerides and cholesterol in the blood and improve lipid metabolism. At the same time, the components such as lignans in flaxseed oil also have antioxidant effects, which can reduce lipid peroxidation and prevent vascular damage. In summary, the present invention compounds camellia oil, linseed oil and perilla oil, and strictly controls the ratio of the three, to obtain a compound composition rich in nutrients and having a good lipid-lowering effect. The compound composition can play a health-care function of reducing lipids while meeting the human body's nutritional needs for oils and fats, and is suitable for people with high blood lipids, and has a broad market prospect. The results of the embodiment show that the camellia oil compound composition of the present invention can reduce the TC, TG and LDL contents in the serum of high-fat animal model mice, indicating that it has a certain lipid-lowering effect.
