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
The invention belongs to edible oil product field, relate in particular to based corn oil for children only of a kind of DHA of containing and preparation method thereof.
Background technology
Since the nineties in last century, DHA is that the unrighted acid DHA is a large focal spot of child nutrition article always.Britain brain nutrient research institute croft professor and Japanese famous nutritionist Austria are by accounting for the secret that beautiful professor has disclosed DHA the earliest, and their result of study shows: DHA is one of people's brain development, important substance of growth.
Along with the progress of society and the raising of people's living standard, people pay attention to healthy diet more, and the head of a family also is happy to drop into substantial contribution and buys the requirement of growing that various nutriment satisfy child.For the 2-10 children in year, the critical period of health and intelligence development also is the important period of children through the various nutrition of food intake just.How can guarantee child take in capacity, directly influence intelligence development critical nutrients---DHA receives the numerous head of a familys' attention especially.
Simultaneously the expert points out, directly obtaining DHA on one's body from marine fishes is difficulty very, modern science can be from marine microalgae the high DHA of dna purity, ordinary consumer can reach additional purpose through edible DHA series products fully.Owing to the absorption of human body reason, especially infant's absorbability is relatively poor, and every day, the magnitude of recruitment of DHA should be greater than the intake of regulation; At present; The main path that replenishes children DHA is the edible nutriment such as milk powder that contain DHA, and DHA adds with powder form in the milk powder, and the purity of DHA is lower in the pulvis; Be generally about 10%, impurity and useless composition account for larger proportion.The necessity that utilizes people all will eat every day---edible oil replenishes DHA and then is in the blank phase of product.
Summary of the invention
The objective of the invention is to, overcome the deficiency of prior art, the based corn oil for children only that a kind of DHA of containing is provided is to aim at a intelligence developing type children special-purpose edible oil that the children in 2-10 year develop, and does not contain EPA basically, and the purity of DHA is high.The present invention also provides the preparation method of the based corn oil for children only that contains DHA.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of based corn oil for children only, contain DHA in the said based corn oil for children only.The percetage by weight content of DHA in based corn oil for children only is: 0.3-1.2%, surplus is a corn oil.
The present invention also contains the lutein of 0.005-0.2wt%.Because it is oxidized that DHA is prone to, lutein is the patron saint of DHA, can promote the big cerebro-retinal growth of infant, and promotes the absorption of brain to DHA, plays mutual sorbefacient effect.
The preparation method who contains the based corn oil for children only of DHA according to the invention comprises following processing step:
(1) extraction of DHA
A) esterification is got the 100kg refined fish oil and is put into stirred tank, is heated to certain 50-70 ℃ temperature, under agitation adds the ethanol solution that 30-60kg contains NaOH, reacts 5-7 hour down at 60-90 ℃, uses brine wash then, obtains crude fish oil second fat;
B) at vacuum 0.05-0.08MPa, temperature is 30-70 ℃ and obtains the fish oil carboxylate after the dehydration deodorization down the crude fish oil second fat that obtains after the dehydration deodorization esterification through thin film evaporator;
C) through single flash, DHA and EPA total amount are more than or equal to 60% in the refined fish oil that obtains in the secondary molecular distillation apparatus for the fish oil carboxylate that obtains among the distilation steps b.
D) redistillation obtains DHA concentrate through twice distillation with refined fish oil in the secondary molecular distillation apparatus, and wherein DHA content is greater than 86%.
(2) with each component according to certain ratio of weight and number under nitrogen protection, after stirring with 20-50 rev/min, quantitative package.
The preparation method who contains the based corn oil for children only of DHA of the present invention, middle a) the described salt solution of step (1) is that concentration is the Nacl solution of 1%-8%.
The preparation method who contains the based corn oil for children only of DHA of the present invention, c in the step (1)) temperature of first order molecular clock is that 115-125 ℃, pressure are 30-70Pa in the described secondary molecular clock; The temperature of second level molecular clock is that 120-130 ℃, pressure are 8-15Pa.
The preparation method who contains the based corn oil for children only of DHA of the present invention, d in the step (1)) temperature of first order molecular clock is that 103-115 ℃, pressure are 5-12Pa in the described secondary molecular clock; The temperature of second level molecular clock is that 105-120 ℃, pressure are 1-8Pa.
According to Chinese Soclety of Nutrition in " the DRIs Chinese DRIs " of writing in 2000 age-based section provide to meals in the balanced ratio of ω 6, ω 3 be fit to Chinese balance suggestion---the golden ratio that 2 years old to 60 years old was 4～6:1 is carried out rational allocation, simultaneously according to the requirement of the infant DHA every day intake 100mg of World Health Organization (WHO) regulation add the high-purity of from high-quality fish oil, extracting, the balanced allotment of DHA that does not contain EPA forms.
DHA makes through distillation processing repeatedly with molecular distillation technique in the refining deep sea fish oil, and the DHA that is extracted is compared to traditional DHA, and it is good to have a color and luster, and smell is pure, and peroxide value is low, does not contain the characteristics of EPA.Molecular distillation technique has fully shown its unique effect in DHA extracts, operating temperature is low, and heated time is short, fabulous prevention polymerization and the decomposition of DHA; Higher separation degree has effectively guaranteed the desired color and luster of product, smell and purity, has improved product quality.Owing to adopt the multistep molecular distillation technique, EPA is separated from DHA to greatest extent, make end product not contain EPA basically, thereby improved the purity of DHA greatly.
Product of the present invention is an oily liquids, and color is shallow slightly than corn oil, because children's amount is less, manner of packing is taked inner wrapping usually, and its packing specification form has 200ml, 500ml, and 1L etc. make things convenient for family to use, and cooking is cold and dressed with sauce all can.
The invention has the beneficial effects as follows: contain DHA in the based corn oil for children only of the present invention; DHA makes through repeatedly distilling to handle with molecular distillation technique in refining deep sea fish oil; The DHA that is extracted is compared to traditional DHA, and it is good to have a color and luster, and smell is pure; Peroxide value is low, does not contain the characteristics of EPA.Meeting provides high-quality, DHA product selection more reliably more for the children that are in the additional DHA of quick urgent need campaign, simultaneously, also can bring good social benefit and economic benefit to company.
