Description
Technical field
The present invention relates to pigeon eggs technical field of preservation of fresh, and in particular to a method of extending pigeon eggs freshness date.
Background technology
Pigeon eggs is the high-grade nutrient product in current birds, beasts and eggs, and moisture and carbohydrate content ratio egg are contour, still
Its protein, fat and content of ashes ratio egg are low, therefore store transportation fresh-retaining difficulty bigger than egg for pigeon eggs, are unfavorable for
Long distance transportation and long-time are fresh-keeping.
The freshness date of pigeon eggs is generally 30~45 days at present, and common preservation method is ozone sterilization and atoleine film
Either pulullan polysaccharide film or polyacrylic acid film, ozone itself are poisonous gases, can damage cental system, cause to think
Dimension is disorderly, and atoleine and polyacrylic acid have certain toxicity, are medically considered as carcinogen, direct film is in eggshell table
Skin adversely affects health, and pulullan polysaccharide film is that a kind of corn is extracellular water solubility made of fermenting raw materials
Cement polysaccharide, colorless and odorless is nontoxic, is chiefly used in the fresh-keeping application of fresh fruit of vegetables etc., but is used on pigeon eggs that the effect is unsatisfactory,
Therefore urgently a kind of safe and non-toxic method of good preservation effect extends to the fresh-keeping of pigeon eggs.

The method of freshness date.
Technical solution：In order to solve the above technical problem, the present invention provides a kind of method extending pigeon eggs freshness date, packets
Include following steps：
1) hairbrush or blade is used to clear up pigeon eggs surface contaminants, until invisible dirt exists；
2) it is carried out disinfection to it sterilization using ultraviolet light to step 1) treated pigeon eggs；
3) eggshell is covered using food-level white oil sprayed on membrane to step 2) treated pigeon eggs；
4) pigeon eggs after spraying is placed in 2~4 DEG C, fresh-keeping warehouse preserves, and fresh-keeping warehouse keeps certain frequency ventilation.
Wherein, above-mentioned steps 2) uv disinfection radiation intensity be 10000~20000 μ W/cm2。
Wherein, above-mentioned steps 2) ultraviolet disinfection sterilizing time be 1~2h.
Wherein, above-mentioned steps 3) food-level white oil be ArChine Foodtech WO series white oils.
Wherein, above-mentioned steps 3) spray pattern and spray time be：When spraying respectively to pigeon eggs, each pigeon eggs spray
The mist time is 5~10s；When 100 pieces of egg doves spray at the same time, spray time is 30~120s.
Wherein, above-mentioned steps 3) sprayed on membrane thickness be 2~4nm.
Wherein, above-mentioned steps 4) ventilation frequency is that every 5~30min ventilations are primary.
Advantageous effect：The present invention has the following advantages：A kind of method of extension pigeon eggs freshness date of the present invention, use are ultraviolet
The method for the mode that sterilization and food-level white oil sprayed on membrane covering eggshell are combined is fresh-keeping to pigeon eggs progress, which can
At least extend pigeon eggs freshness date 60 days, longest fresh keeping time substantially reduced the market risk up to 105 days.
Specific implementation mode：

Experimental example
(60 pieces) of the pigeon eggs (each group of 60 pieces of embodiment) and control group crossed by test process to Examples 1 to 3 are city
Progress weight-loss ratio determination experiment after the pigeon eggs of conventional treatment on face (4 DEG C of preservations) store 105 days, yolk index, storage time,
It dissipates Huang rate to measure, be averaged.
The comparison of the various indexs of the pigeon eggs of 1 embodiment 1-3 of table and on the market conventional treatment (4 DEG C of preservations)
Note：Yolk situation is also to evaluate one of the important indicator of quality of egg, usually uses yolk index (yolk height and egg
Yellow diameter ratio, referred to as yolk index) reflect the freshness of egg, the yolk index of fresh -laid egg between 0.401~0.442,
The yolk index of common egg is between 0.35~0.4, and when yolk index is less than 0.25, membrane of yolk is easily broken, and occurs dissipating Huang
Phenomenon is second-rate egg.Hough unit is that its index is figured out according to the formula according to dense albumen height in egg size and egg
A kind of advanced method, the quality of egg and the freshness of egg can be weighed, according to surveying and determination, the Hough unit of fresh -laid egg 72 with
On, 100 is optimal, and for medium freshness between 60~72,60 or less is with low quality, and 30 when is most bad.It is to dissipate yellow egg to account for dissipate Huang rate
The percentage of total egg.
By table it can be seen that：Weight-loss ratio, yolk index, Hough unit, scattered yellow rate difference between embodiment 1-3 are not shown
It writes, but extremely notable with control group difference.Conclusion：Embodiment 1-3 is one of the best approach for extending pigeon eggs freshness date.
The above is only a preferred embodiment of the present invention, it should be pointed out that：Those skilled in the art are come
It says, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should be regarded as
Protection scope of the present invention.
