specific Embodiment approach 1

[0009] Specific embodiment one: the steps of the method of this embodiment are as follows;

[0010] Step 1, the egg white powder is packed in a transparent polyethylene plastic bag (PE), and the weight of each bag is 20kg;

[0011] Step 2. Pack the plastic bag containing egg white powder in step 1, and irradiate it with cobalt 60-γ rays. The source intensity is 50,000 curies, the absorbed radiation dose is 3.3 to 5 kGy, and the radiation dose rate is 1.2 ~1.8Gy / min, the egg white powder which is beneficial to preservation and storage of the present invention can be obtained.

specific Embodiment approach 2

[0012] Specific embodiment two: the difference between this embodiment and specific embodiment one is that cobalt 60-γ-ray irradiation treatment is adopted in step two, the radiation absorbed dose is 4kGy, and the radiation dose rate is 1.5Gy / min, which obtains the present invention Preserved and stored egg white powder. This embodiment is the best embodiment.

[0013] research shows:

[0014] Irradiation of egg white powder has a remarkable fresh-keeping effect. The egg white powder irradiated at a radiation dose of 3.5-5kGy can effectively kill the microorganisms in the egg white powder and prolong the shelf life of the egg white powder; the irradiated egg white powder is not only better It maintains the original physical and chemical indicators, good functionality and appearance color, and also maintains good palatability, which is suitable for use in the food industry.

[0015] When the irradiation dose is 4kGy, the protein and fat in the egg white powder are damaged by ...

Abstract

A method for freshness-retaining storage of egg white powder relates to the freshness retaining method of food. The method solves the problem that the existing egg white powder is quite easy to breed worms and mildew and not suitable for storage. The irradiation treatment method of the method for freshness-retaining storage of egg white powder comprises the following steps of: 1, packaging the egg white powder with a transparent polyvinyl plastic bag; and 2, performing irradiation treatment on the plastic bag containing the egg white powder in the step 1 by using cobalt 60-gamma, wherein the irradiation adsorbed dose is 3.3-5 kGy and the irradiation dose rate is 1.2-1.8 Gy / min; therefore, the egg white powder suitable for freshness-retaining storage is obtained. The irradiated egg white powder obtained by the method provided by the invention is obvious in freshness retaining effect; irradiation is capable of effectively killing microorganisms in the egg white powder, thereby prolonging the quality guarantee period and the storage period of the egg white powder; the nutrient substances in the irradiated egg white powder are not influenced by irradiation and the microbiological indicator thereof completely satisfies the national food standards; no pathogenic bacterium is detected; and simultaneously, the production cost is also reduced. The method for freshness-retaining storage of egg white powder can be widely applied to the food industries.

Description

technical field [0001] The invention relates to a fresh-keeping method for food. In particular, it relates to a method beneficial to fresh-keeping and storage of egg white powder. Background technique [0002] At present, egg white powder is spray-dried from egg white. It is one of the high-quality animal proteins with good nutritional value and rich in amino acids. Egg white protein is widely used in the food industry because of its good functional properties. The use of egg white powder can make the flavor of the product better without increasing the cost. In meat filling products, it can greatly improve the bad phenomena such as retrogradation, divergence, and slag caused by the use of starch in the product, improve the product structure, and improve the quality of the product. Product quality; used in the aquatic product processing industry, the use effect is better, can effectively reduce production costs, save storage costs, and facilitate transportation; good econom...
