Premix and feed capable of efficiently coloring yolk and stabilizing color after heating

Abstract

The invention discloses a premix and a feed capable of efficiently coloring yolk and stabilizing the color after heating. The feed comprises the following components in parts by mass: corn, soybean meal, corn protein powder, rice bran, turmeric powder, soybean phospholipid powder, soybean oil, stone powder, calcium hydrophosphate, sodium chloride, baking soda, choline with the purity of 60%, methionine, lysine, phytase, composite vitamins, a trace element premix and a natural haematochrome premix. According to the feed, curcumin is matched with aniseed to provide yellow pigment; a natural haematochrome premix is used for providing haematochrome such as capsorubin, capsorubin and carotene; natural pigment absorption can be promoted by matching with proper grease, natural chromaticity can beprotected from being oxidized by matching with antioxidant substances, the chromaticity of fresh yolk can averagely reach 13 degrees or above, yolk coloring is stable after heating, intestinal tracthealth can be improved by matching with intestinal tract immunity improving substances, and nutrient absorption is promoted.

Description

technical field [0001] The invention relates to a chicken feed, in particular to a premixed material and a feed with efficient coloring of egg yolk and stable color after heating. Background technique [0002] The chromaticity of the fresh egg yolk of ordinary eggs can generally reach 6-11 degrees (DSM color fan standard), but the color of the egg yolk changes greatly after heating, and it will fade to 1-2 degrees. This problem makes eggs be greatly restricted in food processing, especially in cake and pastry companies that use a large amount of eggs; and this kind of eggs will also be disliked by consumers who pay attention to food color, fragrance, and hotels and restaurants. happiness. [0003] Usually, the sources of yolk pigment mainly include natural pigments and synthetic pigments: natural pigments mainly come from corn and by-products in bulk raw materials, marigolds rich in natural pigments, raw red pepper powder, meal or its extracts, etc. , The synthetic pigment...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of the existing ordinary egg yolks, which have obvious light yolk fading and unstable natural coloring, and high cost, the invention provides a premix and feed with efficient coloring of egg yolk and stable color after heating, and adopts turmeric powder to replace the commonly used Marigold powder and its extracts, combined with aniseed ingredients to provide natural yellow pigments, such as lutein, zeaxanthin, curcumin, etc., can save formulation costs; use natural red pigment premix to provide red pigments, such as capsanthin , capsanthin, carotene, etc., combined with appropriate oils can promote the absorption of natural pigments, combined with antioxidant substances can protect the natural color from oxidation, and can make fresh egg yolks reach an average of 13 degrees and above, and heating After egg yolk coloration is stable
