Problems solved by technology

[0002] In recent years, the production of poultry eggs has developed rapidly and the market supply is sufficient. However, there is a large backlog of eggs and even spoilage in the production area during the peak production season, which has caused huge economic losses to the poultry industry.
Commercially available fresh eggs have not been fresh-keeping treated and have a short shelf life. Some fresh eggs have decreased freshness indicators, hygienic conditions, and nutritional value after purchase, and even loose yellow and deteriorate, losing their edible value.

[0017] The hydrophobic agent can be one or more of food-grade shellac, liquid paraffin, beeswax, polyvinyl acetate, oleic acid, and stearic acid.

[0018] The surfactant can be one or more of Span-80, Span-65, Span-60 and Span-20.

[0019] The invention is applied to fresh-keeping treatment of poultry eggs, and the treatment process is as follows: firstly, the poultry eggs are washed, and then the surface of the poultry eggs is sprayed with a coating agent, and the water is dried.

Embodiment 3

[0021] Weigh 5g of pullulan, 100g of glycerin, 20g of hydrophobic agent, and 50g of surfactant, mix them, add a small amount of ethanol-water solution with a volume ratio of 10:1, heat and stir until completely dissolved, and then use a volume ratio of 10 :1 Dilute to 1L with ethanol-water solution.

[0022] The hydrophobic agent can be one or more of food-grade shellac, liquid paraffin, beeswax, polyvinyl acetate, oleic acid, and stearic acid.

[0023] The surfactant can be one of Span-80, Span-65, Span-60, Span-20 or any combination of several.

[0024] The invention is applied to fresh-keeping treatment of poultry eggs, and the treatment process is as follows: firstly, the poultry eggs are washed, then immersed in the film coating agent for 200 seconds, and the water is taken out and dried in the air.

Abstract

The invention relates to the technical field of fresh keeping, and in particular to an egg coating fresh-keeping agent. The invention aims to provide a natural, nontoxic and safe egg coating fresh-keeping agent. The technical scheme of the invention comprises that: each liter of the egg coating fresh-keeping agent contains 5 to 100g of pullulan sugar, 10 to 100g of glycerin, 10 to 50g of hydrophobic agent, 1 to 50g of surfactant, and the balance of solvents. The egg coating fresh-keeping agent has the advantages that: the coating fresh-keeping agent of the invention is used for forming a film on the surface of an egg, so that the exchange of the matters inside and outside the egg shell and infection of various harmful microorganisms can be prevented in the storage process of the egg, the loss of dry matters and moisture can be reduced, and the egg can have a good storage quality.

Description

technical field [0001] The invention relates to the field of fresh-keeping technology, in particular to a fresh-keeping agent coated with poultry eggs. Background technique [0002] In recent years, the production of poultry eggs has developed rapidly and the market supply is sufficient. However, there is a large backlog of eggs and even spoilage in the production area during the peak production season, which has caused huge economic losses to the poultry industry. Commercially available fresh eggs have not been fresh-keeping treated and have a short shelf life. Some fresh eggs have decreased freshness indicators, hygienic conditions, and nutritional value after purchase, and even loose yellow and deteriorate, losing their edible value. Therefore, solving the storage and preservation of poultry eggs has always been a focus of attention. [0003] Commonly used poultry egg storage methods include refrigeration, immersion, modified atmosphere, radiation, and coating methods. T...
