Problems solved by technology

[0006] Studies have found that if DHA is lacking in the critical stage of brain development, it may lead to abnormal growth and development of fetal brain cells and optic nerve cells, resulting in mental retardation and visual developmental disorders; the baby's brain development process is delayed or blocked, resulting in mental retardation, and may also cause children. inattention

Embodiment 1

[0024] Comprising the following components by weight percentage: DHA is 1.0%, EPA is 0.8%, and the balance is corn oil,

[0025] The preparation method comprises the following process steps:

[0026] (1) Extraction of DHA

[0027] a) Esterification Take 100kg of refined fish oil and put it into a stirring tank, heat it to a certain temperature of 50-70°C, add 30-60kg of anhydrous ethanol solution containing sodium hydroxide under stirring, and react at 60-90°C for 5-7 hours, and then wash with a Nacl solution with a concentration of 1%-8%, to obtain crude fish oil ethyl fat;

[0028] b) The crude fish oil ethyl fat obtained after dehydration, deodorization and esterification is dehydrated and deodorized by a thin-film evaporator at a vacuum degree of 0.05-0.08 MPa and a temperature of 30-70°C to obtain fish oil esterification;

[0029] c) the fish oil esterification product obtained in the distillation step b is distilled more than twice in a secondary molecular distillation...

Abstract

The invention belongs to the field of edible oil products, and in particular relates to DHA-containing corn oil special for pregnant and nursing women and a preparation method thereof. The invention adopts the technical scheme that the corn oil special for the pregnant and nursing women contains DHA. The corn oil comprises the following components in percentage by weight: 0.8 to 2.5 percent of DHA and EPA in a total amount and the balance of corn oil, wherein the weight part ratio of the DHA to the EPA is 5 to 4. The invention also provides a preparation method for the corn oil special for the pregnant and nursing women. The corn oil provides more nutrient substances for the pregnant and nursing women, and balances the nutrient composition in the grease so that the nutrient components therein are closer to the nutrient structure of the human body and can meet the requirement of brain growth of embryos and nursing children for the DHA.

Description

technical field [0001] The invention belongs to the field of edible oil products, in particular to a DHA-containing special corn oil for pregnant women and lactating women and a preparation method thereof. Background technique [0002] DHA, or the unsaturated fatty acid docosahexaenoic acid, has been a major focus of children's nutrition since the 1990s. Professor Croft of the British Institute of Brain Nutrition and Professor Oyu Zhanmei, a famous Japanese nutritionist, first revealed the mystery of DHA. Their research results show that: DHA is one of the important substances for human brain development and growth. [0003] To maintain the normal functions of various tissues, the human body must ensure that there are sufficient fatty acids. If they are deficient, they can cause a series of symptoms, including growth retardation, abnormal skin scales, mental retardation, etc. Among various fatty acids, linoleic acid ω6 and a-linolenic acid ω3 are essential fatty acids that ...
