Description of drawings
Fig. 1 is the change curve of protein, fat, content of ashes in the egg-white powder behind the irradiation of the present invention.
The specific embodiment
The specific embodiment one: the step of the method for present embodiment is as follows;
Step 1, egg-white powder adopt transparent polyethylene plastic bag packaging (PE), and every bag of weight is 20kg;
The plastic bag packaging of egg-white powder step 1 is equipped with step 2,, adopt 60Co-γ rays that it is carried out radiation treatment, source strength 50,000 Curie, the irradiation absorbed dose of radiation is 3.3～5kGy, radiation dose rate is 1.2～1.8Gy/min, namely obtains the egg-white powder fresh-keeping, storage that is beneficial to of the present invention.
The specific embodiment two: the difference of present embodiment and the specific embodiment one is in the step 2 to adopt the 60Co-γ rays radiation treatment, and the irradiation absorbed dose of radiation is 4kGy, and radiation dose rate 1.5Gy/min namely gets the egg-white powder of fresh-keeping, storage of the present invention.Present embodiment is best present embodiment.
Studies show that:
Egg-white powder irradiation fresh-keeping effect is remarkable, is the egg-white powder of irradiation under 3.5～5kGy at irradiation dose, can effectively kill the microorganism in the egg-white powder, prolongs the shelf-life of egg-white powder; Egg-white powder behind the irradiation has not only kept original every physical and chemical index, good functional and appearance color preferably, has also kept preferably palatability, is suitable for food industry and uses.
When irradiation dose was 4kGy, irradiation produced certain destruction to the protein in the egg-white powder, fat; In 4～10kGy dosage range, along with the increase of irradiation dose, the loss of protein, fat seldom.In 4～10kGy dosage range, irradiation is little on inorganic salts impact in the egg-white powder, with to compare difference without the egg-white powder of irradiation not remarkable.Although irradiation causes certain destruction to nutriment in the egg-white powder, do not affect the nutritive value of egg-white powder integral body, adopting irradiation technique is to solve the fresh-keeping a kind of effective ways of egg-white powder.
