Abstract

The invention relates to a coating preservation method for eggs. The method comprises the following steps: (1) selecting fresh and crack-free eggs, cleaning the eggs and then adding water to soak the eggs; (2) taking 1 to 2 parts of xanthan gum, 1.6 to 2.05 parts of composite plant essential oil, 0.125 to 0.25 part of licorice flavonoids, 30 to 35 parts of an emulsifier and 50 to 100 parts of ganoderma lucidum polysaccharide, mixing the above-mentioned materials and adding the obtained mixture into water under stirring so as to obtain 1000 parts by weight of an essential oil emulsion; and (3) taking the essential oil emulsion and water according to weight parts, mixing the essential oil emulsion and water so as to obtain a spraying liquid, coating the shells of the eggs with the spraying liquid and drying the eggs at 37 DEG C in the air for preservation. According to the invention, the surface of each egg is coated by a layer of a preservative film which inhibits enzymatic activity of the eggs, alleviates decay of life, achieves the purpose of freshness and quality retention, increases the shelf life of the eggs and saves social cost; moreover, the coated preservative on the surfaces of the eggs is colorless and transparent after drying, so the advantages of safety and low cost are obtained.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a coating preservation method for eggs. Background technique [0002] Eggs have high nutritional value. They not only contain essential nutrients such as protein, fat, minerals and vitamins, but also contain lecithin, cephalin and neurophospholipids, which are indispensable for the human brain and nervous system, especially protein. The content is higher, and it is easy to digest and absorb, and can be used by the human body almost completely, so it can be called high-quality food. Over the years, it has always been one of the important nutritious foods in the daily life of the broad masses of the people. [0003] Eggs are perishable foods, and the deterioration of eggs is closely related to the condition of the eggs themselves, the type and quantity of bacteria, and the environment in which the eggs are located. Whether the microorganisms contaminated inside the egg ...
