Description
Technical Field
The invention belongs to the technical field of edible blend oil, and particularly relates to edible blend oil containing lutein ester and a preparation method thereof.
Background
Edible oil, also known as "edible oil", refers to animal or vegetable fat used in the process of making food, is an indispensable nutrient in human life, and is an important source for providing energy required in life activities. Due to the source of raw materials, processing technology, quality and other reasons, common edible oils are mostly vegetable oils and fats, including millet oil, rapeseed oil, peanut oil, hemp seed oil, corn oil, olive oil, camellia oil, palm oil, canola oil, sunflower oil, soybean oil, sesame oil, linseed oil (linseed oil), grape seed oil, walnut oil, peony seed oil and the like. The simple grease has single component and can not meet the requirement of people on health care. Most of the conventional blend oils are prepared by simply mixing two or more kinds of edible oils such as soybean oil, peanut oil, corn oil, rapeseed oil and the like, and the blend oils are difficult to meet the requirements of consumers in the aspects of oily nutrient components, stability, health care and the like.
Visual fatigue is a series of symptoms and signs mainly caused by discomfort of eyes due to overuse of eyes or overuse of eyes and failure of timely and effective rest. The reason for this may be two: one is that the eyeball is in a search fixation state for a long time, and the extraocular and ciliary muscles are metabolized more, resulting in increased accumulation of metabolic waste products (including oxygen radicals), thereby causing structural damage and functional decline of myocytes. Secondly, the recovery time of macula lutea and retina is prolonged because the cell is over-consumed and the supply of necessary nutrients is not timely. The light radiation damage of the retina becomes serious eye disease threatening the eye health of China. The density of lutein in the retina positively correlates with the level of lutein in the plasma. Therefore, it is a common knowledge that supplementation with lutein can effectively alleviate the occurrence of macular degeneration, and the development of functional foods and dietary supplements using lutein as a functional factor is also a concern in the food industry. Lutein, in turn, is present in plant tissues, usually in the form of a lutein ester formed by combination with fatty acids, which is metabolized in the body to form lutein. Lutein ester has been approved as a new food raw material in China, and the daily intake is not higher than 12 mg.
Lutein ester is a natural antioxidant present in plant cells and is metabolized in the human body to lutein. Lutein is regarded as a 'vitamin of eyes' and has unique effects on preventing cataract, the incidence of senile macular degeneration and the occurrence of juvenile myopia, and lutein also has health care effects of resisting cancer, preventing the occurrence of cardiovascular diseases, enhancing the immunity of the organism and the like.
At present, various health care products for relieving asthenopia, namely lutein/lutein ester, strong acid, which has strong destructive effect on the stability of the lutein/lutein ester, exist in the market, the products rapidly enter the stomach and intestine after oral intake, and the bioavailability of the lutein/lutein ester is greatly reduced due to the low pH (0.9-1.8) of gastric juice.
Chinese patent application CN108013159A discloses a functional edible oil capable of protecting eyes and a preparation method thereof, wherein the functional edible oil comprises the following raw materials: 5-10 parts of almond oil, 20-40 parts of soybean oil and 5-10 parts of linseed oil, wherein the functional additive consists of lutein and vitamin A, and the content of the lutein is not more than 0.8g per kg of the functional edible oil; the vitamin A content is 6-10 mg. Although the invention adds a certain amount of lutein, which has the effect of protecting eyes of human bodies, the adopted lutein is easy to be unstable and destroyed under high temperature.
In summary, there is a need to develop an edible blend oil containing lutein ester, which can effectively protect eyesight, alleviate asthenopia symptoms, protect eyes from light damage, delay aging of eyes and prevent pathological changes, is stable and easy to be absorbed by human body, contains unsaturated fatty acid beneficial to human health, and can reduce cholesterol in human body.

Test example II animal Cholesterol test
1. Test materials: the edible blend oil containing lutein ester prepared in the examples 1-3 and the comparative examples 1-2.
2. The test method comprises the following steps: the method comprises the following steps of feeding mice for two weeks, carrying out health examination, randomly dividing 120 healthy mice into 6 groups, namely an obesity model group, a control group and an experimental group, wherein the weight of each mouse is 18-22 g, and the number of the mice is half that of the healthy mice. The obesity model group takes the weight-gaining feed; 15ml/kg of the blend oil and the fattening feed of comparative examples 1-2 are respectively taken by a control group; the experimental groups respectively take 15ml/kg of the blend oil and the fattening feed of the embodiment 1-3 of the invention. The fattening feed is prepared by adding 10g of milk powder, 10g of lard oil, 1.5g of cholesterol and 0.3g of deoxycholic acid into 100g of basic feed. After the feeds of all groups are respectively prepared into fluid feeds, the mice are subjected to intragastric administration for 1 time every day for 7 weeks, the weight is weighed once a week, blood is collected from the heart parts of the mice 24 hours after the last intragastric administration, serum is collected, and the contents of Total Cholesterol (TC), Triglyceride (TG) and high density cholesterol (HDC-C) in the serum of the rats are detected.
3. Test results
The test results are shown in table 2.
TABLE 2 Table of the results of TC, TG, HDC-C detection in mouse serum
As can be seen from the test results in Table 2, the TC, TG and HDC-C contents in the experimental group are obviously lower than those in the obesity model group compared with the obesity model group, and the edible blend oil containing lutein ester provided by the invention is proved to have the effect of obviously reducing the cholesterol content in the body of a mouse.
