Description

Compound tea oil for pregnant women and preparation method thereof

technical field

The invention relates to the technical field of edible oil, in particular to a compound camellia oil for pregnant women and a preparation method thereof.

Background technique

Camellia oleifera (camellia 0leifera Ahel) is a unique woody oil plant in my country. It is mainly distributed in the mountains and hills of 14 provinces (regions) in southern my country. At present, there are about 4 million hectares of Camellia oleifera forests in the country. The annual output of Camellia oleifera seeds exceeds 600,000 tons. Camellia oil extracted from Camellia oleifera seeds has high nutritional value and health care function, and its oleic acid is 3%-7% higher than that of olive oil. Tea oil contains tea polyphenols and camellia glycosides, rich in VE, VD, VK, carotene and squalene. Long-term consumption can enhance the elasticity and toughness of blood vessels, delay atherosclerosis, increase gastrointestinal absorption, and promote endocrine glands. Body hormone secretion, prevention and treatment of neurological decline, improve human immunity, etc. Camellia oil has been listed as a healthy edible vegetable oil to be promoted by the Food and Agriculture Organization of the United Nations. Camellia oil is composed of fatty acids, camellia glycosides, phospholipids, saponins, vitamin E, tannins and other components. Camellia oil is rich in unsaturated fatty acids, up to 93%. Among them, the monounsaturated fatty acid content exceeds more than 75%, and some even reach as high as 90%. The rest are polyunsaturated fatty acids such as linoleic acid and linolenic acid.

Maternal nutrition not only affects the health of pregnant women themselves, but also directly affects the growth and development of the fetus. Scientists at the Mayo Hospital in the United States suggest that during such a critical period of pregnancy, all women should supplement reasonable fatty acids and avoid using refined or hydrogenated edible oils. The lack of omega-6 fatty acids and omega-3 fatty acids in breastfeeding women will lead to problems such as milk production or nipple congestion and swelling. Whether the diet during pregnancy is reasonable or not, science plays an important role in the health of the next generation. In recent years, with the improvement of people's living standards, the diet structure is also changing. However, pregnant women in my country consume too much saturated fatty acids during childbirth, resulting in postpartum obesity, abdominal fat, body shape variation and normal development of the fetus. The main problems are Unreasonable dietary intake of saturated fatty acids, insufficient intake of some essential minerals and vitamins, and unbalanced fatty acids.

According to the census, pregnant women all over the country pay attention to the supplement of DHA, but they ignore that the intake of zinc is insufficient throughout pregnancy. Zinc is very important to the growth and development of the fetus. Zinc deficiency in pregnant women can affect the development of the fetal brain and cause embryonic development. Deformity, fetal growth retardation, growth stagnation and low birth weight infants, etc., insufficient intake of zinc-containing foods and excessive intake of refined foods by pregnant women are the main reasons for zinc deficiency during pregnancy.

Vitamin A is essential for maintaining normal vision, growth, cell differentiation, reproduction and the integrity of the immune system. According to the dietary survey results of pregnant women, the intake of vitamin A has not reached the RDA level, but taking too much vitamin A can lead to fetal malformation, so it is necessary to master the intake. n-3 polyunsaturated fatty acids such as EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), LNA (linolenic acid), are important components of brain cells, and are important for stabilizing cell membrane function and growth. Development plays an important role, especially in promoting the growth and development of the brain of fetuses and infants.

The above-mentioned ingredients are not contained in general meat, vegetables and fruits, etc. According to the current census, it is found that the above-mentioned fatty acids in the diet of pregnant women in my country are seriously lacking.

Contents of the invention

detailed description

In order to describe the technical content, achieved objectives and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments.

Camellia oil is composed of fatty acids, camellia glycosides, phospholipids, saponins, vitamin E, tannins and other components. Camellia oil is rich in unsaturated fatty acids, up to 93%. Among them, the monounsaturated fatty acid content exceeds more than 75%, and some even reach as high as 90%. The rest are polyunsaturated fatty acids such as linoleic acid and linolenic acid. Unsaturated fatty acids are essential fatty acids for the human body and are divided into monounsaturated fatty acids (mainly oleic acid) and polyunsaturated fatty acids. Excess saturated fatty acid is the chief culprit of human diseases. If its content exceeds 12%, fat accumulation will occur in the human body, thus causing serious heart diseases such as high blood pressure, hyperlipidemia, and arteriosclerosis. Monounsaturated fatty acid is a kind of safe fatty acid, which is very beneficial to the human heart, brain, lungs and blood vessels.

More than 80% of peanut oil components are unsaturated fatty acids, including linoleic acid, linolenic acid, arachidonic acid and other unsaturated fatty acids necessary for the human body. Rich in fat, lecithin, vitamins A, B, E, K, zinc, calcium, phosphorus, iron and other elements, rich in nutrition. Among them, the content of trace element zinc is also the highest in edible oils, with 8.48 mg of zinc per 100 grams of peanut oil.

Deep-sea fish oil is fat extracted from the liver of sharks, cod, etc., and mainly contains vitamin A and vitamin D.

Linolenic acid is the precursor of DHA and EPA, and the body's own enzymes can convert linolenic acid into DHA and EPA.

The key idea of the present invention is that tea oil is rich in monounsaturated fatty acid and is suitable as base oil, which can be supplemented with vitamins A, D, zinc, DHA, EPA, etc. that pregnant women lack in combination with deep-sea fish oil, soybean oil, and peanut oil.

Existing edible oils are mainly composed of fatty acids and glycerin. Edible oil, as the main source of fat and an energy substance necessary for human beings every day, can be a favorable carrier for supplementary products such as DHA. But at the same time, the daily intake of edible oil should also be properly controlled. Excessive intake of oil, in addition to causing obesity, will also lead to excess fatty acids in the blood, leading to diabetes and cardiovascular and cerebrovascular diseases. Camellia oil (the content of saturated fatty acid is 4%-6% lower than that of olive oil), the golden ratio of Ω3 and Ω6 is also better than that of olive oil; the golden ratio of 1:4 is more suitable for infants and young children at 1:4-1:6 , this problem is avoided to a certain extent.

According to research, monounsaturated fatty acids are not sensitive to oxidation, but polyunsaturated fatty acids such as DHA and EPA added in the compound camellia oil for pregnant women of the present invention are sensitive to oxidation, such as DHA is easily oxidized to produce a large amount of free radicals and oxides, which bring Oxidative stress, so adding vitamin E and β-carotene as antioxidants in an appropriate amount ensures the stability of compound tea oil for pregnant women and eliminates the oxidative stress of its metabolism in the body.

Vitamin E and β-carotene are fat-soluble antioxidants, and the combination of the two has a synergistic effect on antioxidant activity. It can not only inhibit the active oxidation of oil, but also inhibit the photooxidation. Beta carotene is the precursor of vitamin A. As long as it exists in the human body, when vitamin A is needed, it can be produced by β-carotene at any time. It acts as an antioxidant when not needed, eliminating free radicals and extending shelf life.

Experiments have shown that taking 10g of PUFA (mainly DHA and EPA) per day will cause more than two times the increase in peroxides in urine samples, while taking vitamin E and 500mg of β-carotene at the same time will reduce peroxides in urine samples by four times (compared to taking PUFA).
