Embodiment 1

[0021] (1) Preparation of composite coating solution: mix pullulan, glycerin and gum arabic in a weight ratio of 3:1:2, add water and stir to make a solution with a solid content of 2.7%, and then ultrasonicate at a power of 150W After 15 minutes of treatment, add lysozyme and chitinase (weight ratio: 1:3), so that the enzyme content reaches 0.75% by weight of the solution;

[0022] (2) Preservation by smearing: wash fresh eggs, dry them, soak them in the compound coating solution for 10 seconds, take them out and dry them at 60°C.

Embodiment 2

[0024] (1) Preparation of composite coating solution: mix pullulan, glycerin and gum arabic in a weight ratio of 2:3:1, add water and stir to make a solution with a solid content of 5%, and then ultrasonicate at a power of 100W After 30 minutes of treatment, add lysozyme and chitinase (weight ratio: 1:1), so that the enzyme content reaches 0.5% by weight of the solution;

[0025] (2) Preservation by smearing: wash fresh eggs, dry them, soak them in the composite coating solution for 20 seconds, take them out and dry them at 40°C.

Embodiment 3

[0027] (1) Preparation of composite coating solution: mix pullulan, glycerin and gum arabic in a weight ratio of 5:0.5:0.5, add water and stir to make a solution with a solid content of 1%, and then ultrasonicate at a power of 500W After 5 minutes of treatment, add lysozyme and chitinase (weight ratio: 1:5), so that the enzyme content reaches 1.5% by weight of the solution;

[0028] (2) Preservation by smearing: wash fresh eggs, dry them, put them into the compound coating solution and soak them for 5 seconds, take them out and dry them at 70°C.

Abstract

The present invention discloses edible compound film coating liquid used for preservation of eggs. The compound film coating liquid is composed of pullulan, glycerin, arabic gum, a bacteriostatic agent and water. The pullulan, glycerin and arabic gum are mixed at a weight ratio of (2-5):(0.5-3):(0.5-3), water is added for stirring, and a solution with a solid content of 1-5% is prepared, then a ultrasonic treatment at a powder of 100-500 W is conducted for 5-30 minutes, and finally the bacteriostatic agent is added to the solution to enable a weight content of the bacteriostatic agent being 0.5-1.5% to obtain a finished product. The compound film coating liquid can reduce a weight loss rate, maintain a yolk index and stabilize an egg white pH value and a Huff value during egg storage processes, and the film coated eggs can still reach class A or AA after 28 days of storage, so that spoilage and deterioration of the eggs can be better prevented and a shelf life of the fresh eggs is extended.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a composite coating solution for keeping eggs fresh, and also relates to a method for keeping eggs fresh. Background technique [0002] Eggs are an important raw material for food processing. There are 7,000 curved pores on the surface of the eggshell that are invisible to the naked eye to communicate with the environment inside and outside the eggshell. Eggs are exposed to the air. On the one hand, they are easily infected by microorganisms such as bacteria or mold. On the one hand, the moisture and carbon dioxide in the egg will evaporate rapidly, thereby accelerating the spoilage of the egg. In addition, the microbial toxins or pathogenic bacteria produced may endanger the safety of consumers and cause foodborne diseases. Therefore, the preservation of eggs is a hot issue in the research of the food processing industry. [0003] At present, egg preservat...
