Problems solved by technology

The additive type is that the red yeast rice produced or purchased by the researcher is added to the feed; the fermented feed type is that the red yeast rice seeds are inserted into the fermentation raw materials for solid-state fermentation, but due to the way of feed fermentation and the feed raw materials characteristics, not very suitable for solid-state fermentation to produce pigments
[0008] (2) None of them clearly mentioned the types of pigments in red yeast rice products in feed:
[0009] In the existing reports, whether it is self-made or purchased red yeast rice products, most of them only mentioned the use of red yeast rice or red yeast rice pigments in general, and did not explicitly mention the type of pigment in the red yeast rice products in the feed.
[0010] (3) Lack of qualitative and quantitative methods for pigments:
[0016] (5) Some red yeast pigments are not stable and changeable:
[0018] (6) Improper control of monascus pigment in feed will affect feed users' judgmen

[0073] Embodiment 1: the preparation of red yeast orange pigment material

[0074] Monascus orange pigment is prepared as follows:

[0075] The production process of Monascus orange raw material is as follows: Figure 7 Shown:

[0076] The preparation method of the monascus orange pigment is as follows: inoculate the Monascus seed liquid producing the monascus orange pigment into (g / L) cornstarch 60, ammonium sulfate 5.0, KH 2 PO 4 2.0,K 2 HPO 4 2.0, MgSO 4 ·7H 2 O 0.5, CaCl 2 0.1, FeSO 4 ·7H 2 O 0.01, ZnSO 4 ·7H 2 O 0.01, MnSO 4 ·H 2 O 0.03, NaNO 3 2.0, lactic acid to adjust the pH to 4.0, the inoculum amount, 10%; after 120 hours of fermentation, the fermentation is ended, and the color value of the fermentation liquid: 450-600U / mL. Add 10-20% (according to the volume of fermentation broth) soybean oil to the fermented liquid, stir at 30°C for 30 minutes, centrifuge, collect the oil phase by centrifugation, add cornstarch 1-2 times the mass of the oil phas...

Embodiment 2

[0079] Embodiment 2: the preparation of red yeast yellow pigment material

[0080] Monascus yellow pigment is prepared by the following method:

[0081] The production process of Monascus yellow pigment is as follows: Figure 8 Shown:

[0082] The preparation method of Monascus yellow pigment is: inoculate the Monascus seed liquid producing Monascus yellow pigment into (g / L) cornstarch 60, ammonium sulfate 5.0, KH 2 PO 4 2.0,K 2 HPO 4 2.0, MgSO 4 ·7H 2 O 0.5, CaCl 2 0.1, FeSO 4 ·7H 2 O 0.01, ZnSO 4 ·7H 2 O 0.01, MnSO 4 ·H 2 O 0.03, NaNO 3 2.0, lactic acid to adjust the pH to 4.0, the inoculum amount, 10%; after 120 hours of fermentation, the fermentation is ended, and the color value of the fermentation liquid: 450-600U / mL. Add 10-20% (according to the volume of fermentation broth) soybean oil to the fermentation broth, stir at 30°C for 30 minutes, centrifuge, collect the oil phase by centrifugation, add cornstarch 1-2 times the volume of the oil phase, and ...

Embodiment 3

[0086] Embodiment 3: the preparation of monascus red pigment material

[0087] The monascus red pigment is converted from the residual pigment in the fermentation broth after the oil phase is separated from the monascus yellow pigment or the monascus orange pigment fermentation broth of Example 1 or Example 2. The amount of pigment in the fermented liquid after separating the oil phase is about one-third of the amount of the pigment in the fermented liquid.

[0088] The production process of Monascus red pigment is as follows: Figure 9 Shown:

[0089] Add 3-5% (mass volume ratio) feed material (corn flour or soybean meal powder containing protein) in the fermented liquid after embodiment 1 or embodiment 2 centrifugation oil phase, and be warming up to certain temperature (50-60 degree) for a certain period of time (30-60min), and some residual pigments in the fermentation broth react with the proteins, peptides and amino acids in the feed materials to produce monascus red p...

Abstract

The invention discloses a laying hen feed capable of increasing yolk chromaticity and realizing accurate proportioning, and belongs to the technical field of biological fermentation feed production. Amonascus pigment material in the laying hen feed is produced from monascus through a liquid fermentation method, the chemical structure and the content stability of monascus yellow pigment and monascus orange pigment in the monascus are protected through a series of key technologies and measures. The monascus pigment material can be added into the feed according to a certain proportion after color value measurement, wherein the color value of the monascus yellow pigment in the feed is 0.4-10 KU/Kg, the color value of the monascus orange pigment is 0.4-12 KU/Kg, and the color value of monascusred pigment is 1-15 KU/Kg. The feed provided by the invention can improve the chromaticity value of egg yolk (raw yolk and cooked yolk) of eggs of laying hens fed at a certain growth stage. The invention discloses the effect of the types and the adding amounts of the monascus pigment on improving quality of eggs, accurate ingredient proportioning of the laying hen feed can be realized, and the effect of stably and effectively improving the yolk chromaticity of laying hens is achieved.

Description

technical field [0001] The invention relates to a laying hen feed capable of increasing egg yolk and capable of realizing precise ingredients, and belongs to the technical field of biological fermentation feed production. Background technique [0002] Eggs are the most common nutritious food rich in protein, and there is a huge demand at home and abroad. The color depth of egg shells and yolks is one of the key points that consumers pay attention to. The yolk color is formed by the deposition of fat-soluble pigments into the yolk during egg formation. Since modern chicken farms adopt a centralized feeding mode, the sources of natural pigments in laying hen feed mainly come from two aspects, one is from the feed raw materials themselves, such as corn; the other is from the added pigments. Sometimes considering cost and other aspects, there may be insufficient natural pigments in the feed of laying hens, and the laying hens cannot obtain enough natural pigments, which will c...
