Description

Be rich in the production method of DHA and vitamin E composition egg

Technical field

The present invention relates to a kind of production method of egg, especially a kind of stability that does not influence laying hen health and can improve DHA, the production method that is rich in DHA and vitamin E composition egg of prolongation shelf life of products.

Background technology

Polyunsaturated fatty acid (PUFA) can keep the mobile relatively of cell membrane, to guarantee the normal physiological function of cell; Make the cholesterol esterification, reduce blood cholesterol and triglycerides; Reduce blood viscosity, improve blood microcirculation; Improve the activity of brain cell, enhance memory power and thinking ability.For this reason, polyunsaturated fatty acid (PUFA) becomes the nourishing healthy hot research fields.At present, more for research in the polyunsaturated fatty acid is ω-3 and ω-6 series.ω-3 series has alpha-linolenic acid (ALA), EPA, DHA etc., is mainly derived from the deep-sea algae and reaches the abyssal fishes as food; ω-6 series has linoleic acid (LA), and arachidonic acid (AA) etc. are mainly derived from vegetable fat.There are some researches show that there are the competition effect in ω-6PUFA and ω-3PUFA in metabolism; The two must keep suitable ratio in meals; Otherwise can cause nutrient imbalance; Therefore WTO advises ω-6/ ω-3=(5-10): 1, and Japan suggestion ω-6/ ω-3=(2-4): 1, China suggestion ω-6/ ω-3=(4-6): 1.Yet, there is survey data to show, ω-6PUFA is obviously higher in the Chinese meals, and ω-6/ ω-3 ratio is extremely uneven, causes body fat mass in human body too much, and cholesterol is too high, thereby causes the generation of angiocardiopathy.

DHA is commonly called as " brain gold ", is the important member of ω-3PUFA family, except that having ω-distinctive physiological function of 3PUFA family; DHA still is a kind of main nutrients that nervous system cell is grown and kept, and is that (content is up to 20% in the human brain cortex, and proportion is maximum in eye retina for brain and amphiblestroid important composition composition; Account for 50%); Therefore, DHA is most important to tire infant intelligence and eyesight growth, also can reduce the risk of suffering from the Alzheimers senile dementia; And can slow down the decline of the cognitive ability relevant with age growth, DHA keeps the bone density peak value of whole body and vertebra that positive role is also arranged to healthy young man simultaneously.Though edible abyssal fishes can play the effect that replenishes DHA, receive the restriction of conditions such as season, region.Current, released the concentrated fish oil goods that are rich in DHA on the domestic and international market, like the SuperuEPA-200 of the U.S.; The Efeed that the big profit of Australia is come, the polyenoid health of China Wuxi etc., but DHA is a long-chain polyunsaturated fatty acid; Have very high biologically active, meanwhile also be easy to take place the bad change of oxidation.For preventing its oxidation, the researcher has thought a lot of ways, as adding anti-oxidant, adopts encapsulated processing, adopt coating technique to be made into powder-product etc., but its effect is unsatisfactory, and has increased production cost greatly.In addition, although these products can reach health-care effect, from people's eating habit, they are more near " medicine ", thereby have limited the acceptability of these products.

Egg always is traditional important foodstuffs that China people are liked; It also is the wholefood of ideals of human being; The egg nutrient balanced composition is rich in needed by human nutrients such as protein, phosphatide, VA, VB, VB2, VD, calcium, iron, lysozyme, therefore is known as " the desirable nutrition library " of human body; Be described as " spirit of life ", often be used to estimate the standard of other animal food.

At present, existingly both at home and abroad utilize raw materials such as fish oil, fish meal, linseed, purple perilla, seaweeds to add in the bird inlay feed, behind the certain hour of feeding, just can obtain being rich in the relevant report of the egg of DHA or ω-3PUFA composition.The Chinese patent of publication number CN102160607A was once announced a kind of " can make egg be rich in the All Pure Nature egg feedstuff of DHA "; Pass through in this patent evenly to mix according to a certain percentage at corn, dregs of beans, fish meal; Through feeding laying hen a period of time, can in egg, improve DHA content.The Chinese patent of the patent No. 200710009909.3 discloses a kind of " improving the chicken feed addictive of DHA content of eggs "; This patented technology will be rich in the ω-fish oil of 3PUFA composition, seawood meal, linseed and make up according to a certain percentage; Be processed into feed addictive afterwards; Its addition accounts for 4 ~ 8% of egg feedstuff weight, through feeding laying hen a period of time, can make that DHA content is increased to 5 ~ 6 times in the egg.The patent No. 200710200246.3 discloses a kind of " food stuff for chicken laying of eggs with brain gold component and method for using and products obtained therefrom "; This patented technology is with after the oil expression of purple perilla seed; The oil and the cake of gained are all joined in the feed as additive; Through feeding laying hen after a period of time, make that DHA content is improved in the egg that hen produces, can reach 0.12% ~ 0.38%.The Chinese patent of publication number CN102415504A has been announced a kind of " containing the egg feedstuff premix of Sargassum protein powder enrichment DHA "; This patented technology is processed into laying-hen compound feed by a certain percentage through the egg feedstuff premix that will contain Sargassum protein powder enrichment DHA; Through feeding laying hen after a period of time; As to account for shell egg ratio 23%, egg size in yolk be that 62 grams calculate, and the content of the DHA of egg reached in per 100 gram shell eggs contain 80 ~ 130mg.

Though above-mentioned document discloses the various methodologies that improves DHA in the egg, the maximum disadvantage that DHA content improves in feed and the product is easy to generate the bad change of oxidation exactly, shortens shelf life of products.Yet, up to now not about how preventing the relevant report of the bad change of DHA oxidation in feed and the egg.

Summary of the invention

The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, a kind of stability that does not influence laying hen health and can improve DHC to be provided, prolonging the production method that is rich in DHA and vitamin E composition egg of shelf life of products.

Technical solution of the present invention is: the production method of a kind of DHA of being rich in and vitamin E composition egg is characterized in that carrying out as follows:

A. the following feed of filling a prescription of the laying hen of feeding;

By quality ratio: corn 500 ~ 650; Dregs of beans 200 ~ 240; Feed is with corn protein powder 15 ~ 20; Rice bran meal 20 ~ 30; Corn DDGS20 ~ 50; Wheat bran 20 ~ 30; Stone flour 65 ~ 70; Calcium monohydrogen phosphate 5 ~ 15; Fish oil 15 ~ 100; Linseed 30 ~ 100; Salt 2 ~ 4; Methionine 0.8 ~ 1; Vitamin premix 0.3 ~ 0.5; Absorbent-type vitamin E powder 0.1 ~ 0.5; Microelement pre-mix material 1 ~ 1.5; Choline Chloride 1 ~ 2; The happy Bio-Aid0.5 of benefit bacterium ~ 1; Section's dimension enzyme 0.25 ~ 0.5; Phytase 0.1 ~ 0.2; Compound betaine 0.2 ~ 0.4;

B. after three weeks, collect the egg that laying hen produced.

The present invention is the feed of multiple compositions such as being added with fish oil, linseed and vitamin E of between laying cycle of laying hens, feeding, and various component interactions can make and be rich in DHA and vitamin E in the egg simultaneously (DHA content is not less than 300mg/100g; Content of vitamin E is not less than 8mg/100g); Satisfy the requirement of day meals recommended intake of authoritative department proposition, improve the stability of DHA in feed and the egg again, guarantee product quality, prolong the product shelf life; The intoxicating phenomenon that also can avoid laying hen to produce simultaneously because of edible too much fish oil, vitamin E; Guarantee that laying hen is healthy, under the prerequisite that guarantees production performance, improved the immunologic function of bird inlay.
