Technical Field

The invention belongs to the technical field of edible blend oil and oil processing, and particularly relates to dietary fatty acid nutrition balance blend oil and a preparation method thereof.

Background

With the gradual improvement of the living standard of people, the production and consumption of edible vegetable oil in China are obviously increased, and the edible vegetable oil can be regarded as an important source of energy and nutrients in daily life of people. Wherein the essential fatty acids required by human body mainly comprise 3 kinds of alpha-linolenic acid of omega-3 series, linoleic acid of omega-6 series and DHA. Arachidonic acid is derived from linoleic acid and, when not synthesized enough, must be supplied by food, and may be classified as essential fatty acids, which are essential for maintaining human health like amino acid balance. However, the physiological needs of human body and the nutrient supply of food need to have a balance relation, and only then can the nutrient balance be kept and the absorption and utilization of nutrients be facilitated. If the balance relationship is not balanced, that is, the food nutrition does not adapt to the physiological needs of the human body, the health of the human body is adversely affected. Therefore, as early as 1977, the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) of the united nations recommended to world authorities the optimal intake ratio of the three fatty acid components in edible fats and oils, namely, Saturated Fatty Acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA), 1:1: 1. The polyunsaturated fatty acids include linoleic acid of the omega-6 series and alpha-linolenic acid of the omega-3 series. In 2014, the chinese nutrition society introduced 2013 edition of chinese resident Dietary nutrient Reference Intakes (DRIs), and recommended standards were specified for two important polyunsaturated fatty acids: omega-6: omega-3 ═ (4-6): 1. In the diet of residents in China, the content of omega-3 fatty acid is very low, and on the contrary, the content of omega-6 series linoleic acid in soybean oil is as high as 60 percent, so that the intake of polyunsaturated fatty acid in a human body is seriously unbalanced, and the intake is one of important reasons for the continuous increase of the morbidity of cardiovascular and cerebrovascular diseases in China. In addition, linoleic acid and linolenic acid are converted in the human body by competing for the same enzymes and are absorbed after conversion. When linoleic acid is taken up excessively, linolenic acid is not converted by enough enzyme and cannot be absorbed naturally. Therefore, the ratio of linoleic and linolenic acid intake must be controlled.

Compared with the common population, the daily life and nutrient absorption of infants and pregnant women are greatly different, and the acquisition of balanced dietary fatty acid is vital to ensuring the normal growth and development of infants and fetuses and the health of pregnant women. The nutrition for babies in different regions and different races is different after birth. After the baby in China is born, linolenic acid and linoleic acid are needed to be supplemented because of the problem of nutrient intake. Edible oil is one of the most important ways to ingest unsaturated fatty acids in the infant and young child period. At present, most of edible oil on the market is single-variety vegetable oil, and cannot meet the requirement of infants on dietary balance of fatty acid. The chinese nutrition society gives the following recommended intakes for different age groups: the year of 0-3, wherein the recommended daily DHA intake is 100 mg; no recommended intake is above 4 years old, and the requirement is 0-3 years old; for infants of 0-6 months, the recommended intake ratio of linoleic acid/linolenic acid is 8.4:1 per day, and the intake amount of arachidonic acid is 150 mg; infants older than 1 year of age recommend a linoleic acid/linolenic acid intake ratio of 6.6:1 per day.

In the infant period, DHA is used as a fatty acid, and has particularly remarkable effects of enhancing memory and thinking ability, improving intelligence and the like. And the people with high DHA content in vivo have stronger psychological bearing capacity and high intelligence development index. The reason is that: the human memory and thinking ability depend on the function of the nervous tissues such as brain cells and synapses for controlling information transmission, i.e., the transmission range, direction and action of information in the nervous system. DHA accounts for about 25% of its fat content in nerve tissues, synapses are key parts for controlling information transmission, and consist of synaptic membranes and gaps, and DHA contributes to structural integrity and functional exertion. When DHA is lacked in diet for a long time, DHA-containing PL is lacked in the synaptic membrane, and the structure is destroyed, thereby adversely affecting the information transfer and thinking ability.

DHA during pregnancy can optimize the phospholipid composition of fetal cerebral pyramidal cells. After 5 months of the fetus, the stimulation of the fetus' hearing, vision and touch due to fetal education can cause the neurons in the sensory center of the fetal cerebral cortex to grow more dendrites, so that the fetus needs to be supplied with more DHA by the mother. In addition to the above brain development, DHA plays an important role in the maturation of retinal photoreceptor cells during infancy. By supplementing a large amount of DHA, the neural cell maturity of the brain and retina of the infant can be improved.

The walnut kernel has high oil content in nuts, and mainly contains unsaturated fatty acid. The walnut oil contains essential fatty acids such as linoleic acid, linolenic acid, and arachidonic acid. Wherein the content of linoleic acid is up to 64 percent, and the content of linolenic acid is up to 10 percent, which is obviously higher than that of colza oil, peanut oil, soybean oil and the like. The proportion of linoleic acid and linolenic acid in the hickory nut oil is 6.4: 1, the proportion of the infant formula to infants of 1 year and older recommended by the Chinese academy of nutrition is 6.6:1 very close to, and also contains 4% arachidonic acid. Therefore, the walnut oil is one of the accepted healthy edible oils in the world.
