60 eggs laid on the same day are taken, 10 eggs are randomly taken for the first time to test the egg yolk dispersion rate, the weight loss rate and the pH value as initial standard indexes. The remaining eggs were divided into 2 groups of 25 eggs, the first group being left at room temperature with the eggs treated by the method of the invention, the second group being left at room temperature without any treatment. Thereafter, 5 eggs were randomly picked from each of the two groups every 10 days, and the above-mentioned index was tested. And analyzing all test results after 30 days to obtain the effect evaluation of the humic acid egg preservative film.
Wherein, the powder of yellow: breaking the situation that whether the egg is yellow or not in the same position; weight loss: weighing with analytical balance (precision of 0.0001), and losing mass of the egg seed before and after storage; pH value: the accuracy was 0.01 as measured by a pH-25 acidimeter.
The test results are shown in table 1 below:
TABLE 1
The results show that the egg preservative film prepared by the invention can effectively prolong the storage time of eggs, and the yellow scattering rate is 16% less than that of untreated eggs, because the humic acid egg preservative film can effectively prevent air and bacteria from entering and delay the putrefaction of eggs. The humic acid egg preservative film can effectively reduce the evaporation of water and the internal dry consumption of eggs, so that the weight loss rate is reduced by 0.8 percent, and meanwhile, the change of the pH value of the treated eggs is obviously lower than that of the untreated eggs, so that the eggs can keep the internal stability of the eggs and the freshness of the eggs.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
