Problems solved by technology

Due to the absorption of the human body, especially the poor absorption capacity of infants and young children, the daily supplement of DHA should be greater than the prescribed intake. At present, the main way to supplement children's DHA is to eat nutritional products such as milk powder containing DHA, and DHA in milk powder It is added in the form of powder, and the purity of DHA in powder is relatively low, generally about 10%, and impurities and useless ingredients account for a large proportion

Embodiment 1

[0024] The weight percent content of DHA in the special corn oil for children is: 0.3%, and the balance is corn oil.

[0025] The preparation method of the special corn oil for children containing DHA of the present invention comprises the following processing 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 distillat...

Embodiment 2

[0034] The weight percentage content of the DHA in the special corn oil for children is: 1.2%, the lutein is 0.2wt%, and the balance is corn oil.

Embodiment 3

[0036] The weight percentage content of the DHA in the special corn oil for children is: 0.8%, the lutein is 0.015wt%, and the balance is corn oil.

Abstract

The invention belongs to the field of edible oil products and particularly relates to DHA-based (docosahexaenoic acid) corn oil for children only and a preparation method thereof. The technical scheme of the invention is as follows: the DHA-based corn oil for children only comprises the following components by weight percentage: 0.3% to 1.2% of DHA and corn oil in balancing amount. The invention further provides a method for preparing the DHA-based corn oil for children only. The DHA is prepared from refined deep-sea fish oil by undergoing distillation treatment for multiple times on the basis of the molecular distillation technique, wherein compared with the conventional DHA, the extracted DHA has the characteristics of good color, pure taste, low peroxide value and EPA-free (eicosapentaenoic acid), thereby providing an option of the DHA-based product having better quality and higher reliability for children badly in need of DHA supplements in growth spurt and bringing good social and economic benefits to manufacturers.

Description

technical field [0001] The invention belongs to the field of edible oil products, in particular to a special corn oil containing DHA for children 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] With the progress of society and the improvement of people's living standards, people pay more attention to healthy diet, and parents are willing to invest a lot of money to buy various nutritional products to meet the growth and development requirements of their children. For children aged 2-10, it is a critical period for physical and intellectual development, and it is also a...
