Description

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

Technical field

The present invention relates to a kind of production method of egg, especially a kind of not affect laying hen healthy and can improve the stability of DHA, extends the production method being rich in DHA and vitamin E component egg of shelf life of products.

Background technology

Polyunsaturated fatty acid (PUFA) can keep the relative flow of cell membrane, to ensure the normal physiological function of cell; Make cholesterol esterification, reduce blood cholesterol and triglycerides; Reduce blood viscosity, improve blood microcirculation; Improve the activity of brain cell, strengthen memory and thinking ability.For this reason, polyunsaturated fatty acid (PUFA) becomes the study hotspot in nutrition and health care field.At present, be ω-3 and ω-6 series for studying more in polyunsaturated fatty acid.ω-3 series has alpha-linolenic acid (ALA), EPA, DHA etc., is mainly derived from deep-sea algae and 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 ω-6PUFA and ω-3PUFA exist Competition in metabolism, the two must keep suitable ratio in meals, otherwise can nutrient imbalance be caused, therefore WTO advises ω-6/ ω-3=(5-10): 1, Japan suggestion ω-6/ ω-3=(2-4): 1, China suggestion ω-6/ ω-3=(4-6): 1.But have survey data to show, in Chinese Diet, ω-6PUFA is obviously higher, ω-6/ ω-3 ratio is extremely uneven, and cause body fat mass in human body too much, cholesterol is too high, thus causes the generation of angiocardiopathy.

DHA is commonly called as " docosapentaenoic acid ", the important member of ω-3PUFA family, except there is the distinctive physiological function of ω-3PUFA race, a kind of main nutrients of DHA or nervous system cell growth and maintenance, that (in human brain cortex, content is up to 20% for brain and amphiblestroid important composition composition, in eye retina, proportion is maximum, account for 50%), therefore, DHA to tire infant intelligence and visual acuity most important, also the risk suffering from Alzheimers senile dementia can be reduced, and the decline increasing relevant cognitive ability to the age can be slowed down, DHA keeps the bone density peak value of whole body and vertebra also to have positive role to healthy young man simultaneously.Though edible abyssal fishes can play the effect of supplementary DHA, be subject to the restriction of the condition such as season, region.Current, domestic and international market is released the concentrated fish oil goods being rich in DHA, as the SuperuEPA-200 of the U.S., the Efeed that the large profit of Australia is come, the vs Duo-xi-kang etc. of China Wuxi, but DHA is long-chain polyunsaturated fatty acid, there is very high biologically active, be meanwhile also easy to oxidation deterioration occurs.For preventing it to be oxidized, researcher designs a lot of ways, and as added antioxidant, adopts encapsulated process, adopt coating technique to be made into powder-product etc., but its effect is unsatisfactory, and considerably increases production cost.In addition, although these products can reach health-care effect, from the eating habit of people, they are closer to " medicine ", thus limit the acceptability of these products.

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

At present, have both at home and abroad and utilize the raw materials such as fish oil, fish meal, linseed, purple perilla, seaweeds to add in bird inlay feed, after certain hour of feeding, just can obtain the relevant report of the egg being rich in DHA or ω-3PUFA composition.The Chinese patent of publication number CN102160607A once announced one " can make egg be rich in the All Pure Nature egg feedstuff of DHA ", pass through at corn, dregs of beans, fish meal Homogeneous phase mixing according to a certain percentage in this patent, by feeding laying hen a period of time, DHA content can be improved in egg.The Chinese patent of the patent No. 200710009909.3 discloses one and " improves the chicken feed addictive of DHA content of eggs ", this patented technology by being rich in the fish oil of ω-3PUFA composition, seawood meal, linseed combine according to a certain percentage, be processed into feed addictive afterwards, its addition accounts for 4 ~ 8% of egg feedstuff weight, by feeding laying hen a period of time, DHA content in egg can be made to be increased to 5 ~ 6 times.The patent No. 200710200246.3 discloses one " food stuff for chicken laying of eggs with brain gold component and using method and products obtained therefrom ", this patented technology is after being extracted oil by purple perilla seed, the oil of gained and cake are all joined in feed as additive, after laying hen a period of time of feeding, in the egg that hen is produced, DHA content is improved, and can reach 0.12% ~ 0.38%.The Chinese patent of publication number CN102415504A has announced a kind of " the egg feedstuff premix containing Sargassum protein powder enrichment DHA ", this patented technology is by being processed into laying-hen compound feed by a certain percentage by the egg feedstuff premix containing Sargassum protein powder enrichment DHA, after laying hen a period of time of feeding, as accounted for shell egg ratio 23% in yolk, egg size is 62 grams of calculating, and the content of the DHA of egg can be made to reach in every 100 grams of shell eggs containing 80 ~ 130mg.

Although above-mentioned document discloses the various methodologies improving DHA in egg, the maximum disadvantage that in feed and product, DHA content improves is exactly easily produce oxidation deterioration, shortening shelf life of products.But, up to now not about how preventing DHA in feed and egg to be oxidized the relevant report of deterioration.

Summary of the invention

The present invention is the above-mentioned technical problem in order to solve existing for prior art, provides that a kind of not affect laying hen healthy and can improve the stability of DHC, extends the production method being rich in DHA and vitamin E component egg of shelf life of products.

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

A. the feed that laying hen of feeding is filled a prescription as follows;

By quality ratio: corn 500 ~ 650, dregs of beans 200 ~ 240, feed corn protein powder 15 ~ 20, rice bran meal 20 ~ 30, corn DDGS 20 ~ 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, benefit happy Bio-Aid0.5 ~ 1 of bacterium, section's dimension enzyme 0.25 ~ 0.5, phytase 0.1 ~ 0.2, compound betaine 0.2 ~ 0.4,

B., after three weeks, the egg that laying hen produces is collected.

The present invention feeds to be added with fish oil during Egg Production of Laying Hens, the feed of the Multiple components such as linseed and vitamin E, various component interaction, can make to be rich in egg DHA and vitamin E (DHA content is not less than 300mg/100g simultaneously, content of vitamin E is not less than 8mg/100g), meet authoritative department propose day meals recommended intake requirement, improve again the stability of DHA in feed and egg, ensure product quality, extend the product shelf phase, laying hen also can be avoided because of edible too much fish oil simultaneously, vitamin E and the intoxicating phenomenon produced, ensure that laying hen is healthy, under the prerequisite ensureing production performance, improve the immunologic function of bird inlay.
