Embodiment 1

[0022] a CO 2 The method for the controlled atmosphere preservation of eggs comprises the following steps:

[0023] (1) Put 90 selected fresh eggs with uniform size and clean shells into the modified atmosphere bag, number the eggs before putting them in, and measure the initial weight of each egg.

[0024] (2) After putting in the eggs, add 400g of silica gel desiccant into the modified atmosphere bag.

[0025] (3) Seal the modified atmosphere bag, and fill the modified atmosphere bag with CO through the air inlet of the modified atmosphere bag 2 , followed by CO 2 Detector detects CO 2 content, so that CO 2 The volume fraction reaches 80%.

[0026] (4) Store the inflated modified atmosphere bag in an artificial climate box at 25°C.

Embodiment 2

[0028] Adopt the method identical with embodiment 1, difference is in step 3, CO 2 The volume fraction is 60%.

Abstract

The invention relates to the technical field of eggs preservation and particularly relates to a method for modifying atmosphere to preserve eggs by CO2. The method comprises the following steps of: placing fresh eggs with clean shells into an atmosphere modifying bag; adding a drying agent into an atmosphere modifying bag; modifying the atmosphere and inflating the atmosphere modifying bag with CO2; and preserving packaged eggs in an environment at the temperature of 10-30 DEG C. According to the method, the cost is low, the operation is simple and the preservation effect is remarkable; the method has a good promotional value.

Description

technical field [0001] The invention belongs to the technical field of keeping eggs fresh, and in particular relates to a CO 2 Methods of preserving eggs under controlled atmosphere. Background technique [0002] Eggs are a high-quality and cheap source of protein. my country's egg production ranks first in the world for more than 20 consecutive years, and fresh eggs are mainly consumed (accounting for more than 90% of the total production). There are many egg farming industries in my country, and the distribution is relatively scattered. Eggs are easy to deteriorate during storage, especially in summer when the temperature is high. At present, the storage methods of eggs mainly include liquid immersion method, refrigeration method, film coating method, and modified atmosphere method. People respected. However, most of the modified atmosphere gases used are binary gases and ternary gases, which are relatively expensive, which hinders the further application of modified at...
