Embodiment 1

[0054] This embodiment is used to illustrate the modified atmosphere preservation method for eggs provided by the present invention.

[0055] Put 6 of the fresh eggs selected above into a packaging bag, put the eggs on the egg tray, and then put them in an aluminum foil bag, and use 50% CO 2 +7vol%O 2 +43vol%N 2 The mixed gas is packaged in modified atmosphere with XT-400 vacuum (inflatable) packaging machine. The standard volume of the mixed gas in the aluminum foil packaging bag is 2500ml, and the air pressure in the aluminum foil packaging bag after packaging is 1.3 standard atmospheric pressure. Store in a room temperature library with a temperature of 25°C and a relative humidity of 60%. Sampling on the 6th, 12th, 18th, 24th, and 30th day of storage. Three bags were taken out each time to measure the air cell diameter, Hough unit and protein gel strength, and the results are shown in Table 1.

Embodiment 2

[0057] This embodiment is used to illustrate the modified atmosphere preservation method for eggs provided by the present invention.

[0058] Put 6 of the fresh eggs selected above into a packaging bag, first place the eggs on a pulp egg tray, then put them in an aluminum foil bag, and use 50% CO by volume at a temperature of 15°C and a relative humidity of 90%. 2 +11vol%O 2 +39vol%N 2 The mixed gas is packaged with XT-400 vacuum (inflatable) packaging machine in modified atmosphere. The standard volume of the mixed gas in the aluminum foil packaging bag is 1800ml, and the air pressure in the aluminum foil packaging bag after packaging is 0.8 standard atmospheric pressure. Store at room temperature at a temperature of 15°C and a relative humidity of 90%. Sampling on the 6th, 12th, 18th, 24th, and 30th day of storage. Three bags were taken out each time to measure the air cell diameter, Hough unit and protein gel strength, and the results are shown in Table 1.

Embodiment 3

[0060] This embodiment is used to illustrate the modified atmosphere preservation method for eggs provided by the present invention.

[0061] Put 6 of the fresh eggs selected above into a packaging bag, first place the eggs on a pulp egg tray, then put them in an aluminum foil bag, and use 50% CO by volume at a temperature of 30°C and a relative humidity of 60%. 2 +9vol%O 2 +41vol%N 2 The mixed gas is packaged in modified atmosphere with XT-400 vacuum (inflatable) packaging machine. The standard volume of the mixed gas in the aluminum foil packaging bag is 3600ml, and the air pressure in the aluminum foil packaging bag after packaging is 2.3 standard atmospheric pressure. Store in a room temperature library at a temperature of 30°C and a relative humidity of 30%. Sampling on the 6th, 12th, 18th, 24th, and 30th day of storage. Three bags were taken out each time to measure the air cell diameter, Hough unit and protein gel strength, and the results are shown in Table 1.

Abstract

The invention discloses an atmosphere-modified packaged egg. The atmosphere-modified packaged egg comprises a packaging bag and an egg arranged in the packaging bag and is characterized in that the packaging bag is filled with a mixed gas of CO2, O2 and N2. The invention also discloses an atmosphere-modified egg preservation method. The method comprises the following steps of: (1) putting an egg in the packaging bag; (2) carrying out atmosphere-modified packaging on the packaging bag with the mixed gas of CO2, O2 and N2; and (3) preserving the egg packaged in the step (2) in an environment of 10-40 DEG C. In the atmosphere-modified packaged egg and the atmosphere-modified egg preservation method provided by the invention, O2 is introduced on the basis of a conventional atmosphere-modified egg preservation method so as to improve the preservation quality of the eggs under an anaerobic condition and prolong the preservation time of the eggs. The atmosphere-modified packaged eggs stored at a room temperature can achieve favorable preservation effect, can be locally preserved and have extremely high popularization values.

Description

technical field [0001] The invention relates to a packaged egg and a fresh-keeping method for the egg, in particular to a modified-atmosphere packaged egg and a fresh-keeping method for the egg. Background technique [0002] Eggs are a high-quality and cheap source of protein. my country's eggs have ranked first in the world for more than 20 consecutive years. In 2008, the total egg output reached 22.9687 million tons, accounting for about 40% of the world. Due to the low conversion rate of egg processing in my country, the current domestic consumption of eggs is mainly fresh eggs, accounting for more than 90% of egg production. [0003] Fresh egg consumption has been the main form of poultry egg consumption in my country for many years, and it will still be the mainstream of poultry egg consumption in my country for a long time to come. Due to the restriction of the shelf life of eggs, and the scattered sources of poultry eggs in my country, it takes a long time to collect...
