Method for increasing natural astaxanthin content of eggs

Abstract

The invention discloses a method for increasing the natural astaxanthin content of eggs. The feed for increasing the natural astaxanthin content of eggs is composed of basic feed and a premixed material mixed with natural astaxanthin, the premixed material is formed by mixing natural haematococcus pluvialis, haematococcus pluvialis oil, feed-grade cuttlefish paste or shrimp paste, spiral seaweed powder and edible lactic acid bacteria, and the basic feed is formed by mixing corn, bran, soybean cake, fish oil, salt and methionine. According to the method, natural haematococcus pluvialis and haematococcus pluvialis oil are added to traditional chick feed, the proportion of esterified astaxanthin in the eggs is increased, the loss amount of astaxanthin in the egg cooking process is reduced, the feed favor is improved by adding the cuttlefish paste or shrimp paste, spiral seaweed powder and edible lactic acid bacteria, the food digestibility and biological value are increased, the astaxanthin content in the eggs is greatly increased, the growth environment is controlled, and astaxanthin accumulation is promoted.

Description

technical field [0001] The invention relates to the technical field of poultry eggs, in particular to a method for increasing the natural astaxanthin content of eggs. Background technique [0002] Astaxanthin is an essential element for the human body and has a variety of physiological effects, such as anti-oxidation, anti-tumor, cancer prevention, immunity enhancement, and vision improvement. Generally, adults need to meet the daily intake of 10 mg. Astaxanthin intake. [0003] Under normal feeding conditions, eggs will not contain natural astaxanthin. At present, there are generally two ways to feed laying hens to have astaxanthin: one is to synthesize astaxanthin or Phaffia rhodozyme Feeding laying hens, so that the eggs have a certain amount of astaxanthin for the human body to absorb, but the astaxanthin contained in the eggs is D-astaxanthin, which cannot be absorbed by the human body and has certain toxicity. Synthetic astaxanthin and red astaxanthin Phaffia yeast f...

[0003] Under normal feeding conditions, eggs will not contain natural astaxanthin. At present, there are generally two ways to feed laying hens to have astaxanthin: one is to synthesize astaxanthin or Phaffia rhodozyme Feeding laying hens, so that the eggs have a certain amount of astaxanthin for the human body to absorb, but the astaxanthin contained in the eggs is D-astaxanthin, which cannot be absorbed by the human body and has certain toxicity. Synthetic astaxanthin and red astaxanthin Phaffia yeast feeding food directly used by humans violates relevant national laws;

[0004] Second, Haematococcus pluvialis is the only natural source of astaxanthin identified by the Ministry of Health of China in 2010 as a new resource food catalog. By feeding Haematococcus pluvialls, eggs have astaxanthin, but traditional feed formula and feeding methods The egg conversion rate of astaxanthin contained in Haematococcus is extremely low, usually not more than 10%
