Problems solved by technology

The traditional method of producing lutein eggs involves adding lutein feed to the diet of laying hens to promote the deposition of lutein in the egg yolk, but there are the following problems: (1) The enrichment content is low (about 1 mg) and it is not easy to Control; (2) Long production cycle; (3) High production cost; (4) Lutein is enriched inside the egg, lacking additional cultural connotations in perception
[0007] As an alternative technology, the method of preparing lutein functional eggs with shells can be expected to solve the above problems, and this method has not been reported at home and abroad.

Abstract

The invention discloses a method for preparing a lutein visual function intensifying egg by nondestructively penetrating an avian eggshell membrane. The method comprises the steps of enzymolysis treatment of the eggshell membrane, treatment with a lutein penetrating agent, vacuum packaging and ultrahigh pressure treatment and the like. According to the method provided by the invention, mainly through firstly carrying out the enzymolysis treatment on the eggshell membrane of an egg, the permeability of the eggshell membrane is ameliorated; the penetrability of an eggshell is promoted through the ultrahigh pressure treatment; thus, the penetration efficiency of lutein and the content of the lutein in the egg are improved; further, the problems that the lutein is low in enrichment content, and further, is difficult to control, long in production period and high in production cost and the like in a conventional method are solved; meanwhile, after the treatments of the above steps, the physical characteristics of the color, the aroma and the taste of the egg cannot be changed either; the storage of a lutein functional egg is facilitated; and moreover, the method is green, environment-friendly, safe and reliable in treatment process.

Description

technical field [0001] The invention relates to the technical field of poultry egg processing, in particular to a method for preparing lutein-enhanced visual function eggs by non-destructive penetration of poultry egg shell membranes. Background technique [0002] So far, the main method of producing functional factors at home and abroad is to increase the content of functional factors in poultry eggs through feed feeding. However, there are many disadvantages such as low content, difficult control, long production cycle, extremely low conversion utilization rate, and high production cost. However, there has been no breakthrough in the technology of preparing functional poultry eggs by the eggshell direct infiltration method, and there have been no reports so far. [0003] The functional poultry egg products prepared by the direct infiltration method with shells not only have the function of nutritional enhancement; but also have a sense of mystery, because the functional f...
