Harmless extraction cost of lutein is high

The blogger detected a content of 0.399mg/kg of lutein in the yellow swan egg. Does it exceed the standard? What is the standard?

Li Zhuanjian said that according to the report of the World Health Organization (WHO), the recommended dosage is 0-0.03mg/kg. In China, there is no regulation in the normative documents for food additives, but according to the "Safety Use Standards for Feed Additives" (Ministry of Agriculture Announcement No. 2625), lutein can be added to feed as a feed additive, with a dosage of 25mg/kg in meat and poultry feed and 8mg/kg in egg and poultry feed.

Some consumers are concerned that the nutritional value of eggs is related to the color of the yolk, which may also be the reason why businesses use colorants to add color to the yolk. Li Zhuanjian analyzed that the core nutritional value of eggs mainly depends on the protein, fat, vitamins, and mineral components, and cannot be judged solely by the color of the egg yolk. The depth of egg yolk color mainly reflects the amount of carotenoids in the mother hen's diet, such as lutein, zeaxanthin, capsaicin, etc. These natural or compliant added pigments will deposit into the egg yolk, making it darker and more orange in color, but this does not necessarily mean that the overall nutritional value of the egg is higher
