Description
Technical Field
The invention relates to a feed additive, in particular to a feed additive for reducing fishy smell in algae DHA enriched quail eggs and application thereof.
Background
Docosahexaenoic acid (Docosahexaenoic acid, DHA), commonly known as brain gold, belongs to omega-3 long chain polyunsaturated fatty acids (omega-3 PUFAs). . A large number of researches show that DHA is a main nutrient for the growth and maintenance of cells in a nervous system, is an important constituent component of brain, nervous tissue and retina, and plays an important role in the aspects of infant intelligence, optic nerve development, prevention and anticancer of adult cardiovascular and cerebrovascular diseases and the like. Life science research shows that DHA has a crucial effect on intelligence and vision development of fetuses and infants. Since DHA is hardly synthesized in animals, mainly by exogenous food supplementation, DHA has become a great focus of nutrition for pregnant and parturients and children in recent years.
Currently, DHA supplements are mainly deep sea fish oil DHA, algae oil DHA, DHA enriched eggs and the like, wherein DHA in the deep sea fish oil is mainly acetyl type, DHA in the algae oil is mainly triglyceride type, DHA in yolk is mainly lecithin type, researches show that the difference of human body absorption rates of DHA in different existing forms is obvious, wherein the formyl type DHA absorption rate and the ethyl type DHA absorption rate are about 21%, the triglyceride type DHA absorption rate is about 57%, and the lecithin type DHA absorption rate is more than 90%.
The egg yolk of the poultry is rich in lecithin, the fatty acid composition in the egg yolk lecithin is extremely easy to be influenced by the diet fatty acid composition, and about 80% of eicosapentaenoic acid (EicosapentaenoicAcid, EPA) and DHA in the egg yolk are directly regulated and controlled by omega-3 PUFA in the diet of the egg-laying poultry. And omega-3 PUFAs in the yolk are mainly present in the phospholipids of the yolk. Thus, the addition of omega-3 PUFAs to the diet of egg-laying birds is an important route for human access to phospholipid-type DHA. The high absorption rate of the lecithin-type DHA makes the DHA-enriched egg product an optimal product for supplementing DHA to human body. Omega-3 PUFA-rich flaxseed (linseed oil), fish oil or microalgae powder, microalgae oil (mainly derived from schizochytrium, ukenella, crypthecodinium cohnii) and the like are added into the feed for laying fowl, so that DHA content in yolk can be obviously increased, but fishy smell and other flavor of the yolk can be increased, and the edible acceptance is reduced. The fishy smell of DHA enriched eggs is mainly influenced by substances such as Trimethylamine (TMA), amino acid, fatty acid and the like, and the expected effect is not achieved at present mainly through means of improving the lipid stability of DHA feed additives, artificially deodorizing aldehyde and ketone volatile substances related to the fishy smell, adding antioxidants and the like.
Therefore, providing a feed additive capable of reducing fishy smell in algae-derived DHA enriched quail eggs is a technical problem to be solved by those skilled in the art.
Disclosure of Invention
In view of the above, the invention provides a feed additive for reducing fishy smell in algae source DHA enriched quail eggs and application thereof, and a method for producing low fishy smell algae source DHA enriched quail eggs by adopting the feed additive. The invention solves the problem of fishy smell and other smell which are unacceptable for algae DHA enriched quail eggs, and has important significance for improving the edible acceptance of DHA enriched eggs and developing DHA enriched egg industry.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a feed additive for reducing fishy smell in algae DHA enriched quail eggs comprises the following raw materials in parts by weight: 40-70 parts of orange peel, 10-20 parts of walnut green seedcase, 10-20 parts of artemia and 10-20 parts of haematococcus pluvialis. Wherein the grain size of the orange peel, walnut green seedcase and artemia powder is 1-2mm, and the grain size of haematococcus pluvialis algae powder is below 200 μm.
Further, the algae source is algae powder, algae oil or algae liquid.
Further, the orange peel is orange peel powder, the walnut green seedcase is walnut green seedcase powder, the artemia are artemia dry powder, and the haematococcus pluvialis is wall-broken haematococcus pluvialis powder.
Further, the granularity of the orange peel powder is 1-2mm, the granularity of the walnut green seedcase powder is 1-2mm, the granularity of the artemia dry powder is 1-2mm, and the granularity of the haematococcus pluvialis powder is less than 200 mu m.
The beneficial effect of adopting above-mentioned further scheme lies in: the scheme provided by the invention is beneficial to improving the appetite of quails, promoting the feeding, reducing the waste of feed, and the wall-broken haematococcus pluvialis algae powder is more beneficial to the absorption of the astaxanthin of quails.
The invention also provides a preparation method of the feed additive for reducing fishy smell in algae DHA enriched quail eggs, which comprises the following steps:
(1) Weighing the raw materials according to the parts by weight;
(2) Crushing the weighed orange peel, walnut green seedcase and artemia by a crusher, and breaking the wall of haematococcus pluvialis by a wall breaking machine;
(3) And uniformly mixing the crushed raw materials to obtain the poultry egg feed additive.
The invention also provides an application method of the feed additive for reducing the fishy smell in the algae DHA enriched quail eggs in the quail feed, wherein the addition amount of the feed additive is 2-4% of the mass of the feed.
Furthermore, the daily feeding amount of the feed containing the additive is 15-30 g/quail; the feeding is carried out twice, and the time interval between the two feeding is 10-12 hours.
The adoption of the method has the further beneficial effects that: by adopting the method to continuously throw the feed for 3-7 days, the DHA content in the quail eggs can be maintained at 400-800 mg/100g yolk, the fishy smell is lower than the perception level of common personnel, the main substance TMA of the algae DHA enriched in the fishy smell of the quail eggs has no obvious difference from the TMA content of the normal quail eggs, and the TMA content in the algae DHA enriched quail eggs is obviously reduced.
The invention has the beneficial effects that: the components in the feed additive are synergistic mutually, so that the fishy smell and other smell of the algae DHA enriched quail eggs can be obviously reduced. Wherein the effective components of pericarpium Citri Junoris powder and pericarpium Juglandis can regulate yolk flavor, reduce TMA formation in quail body, and inhibit fishy smell; the artemia dry powder and haematococcus pluvialis algae powder are rich in high-efficiency antioxidant components, so that the color of yolk can be optimized to be orange red, and the odor such as smell generated by oxidation of polyunsaturated fatty acids such as DHA in the yolk can be inhibited.
