example 1

[0040] Example 1: Opacity Calculation Feasibility Verification of Eggshell Rubber Protective Film of the Same Color

[0041] 30 dwarf chicken pure line and 30 white Laihang eggs from the experimental chicken farm of China Agricultural University were operated according to the above test procedures and ΔT were calculated respectively. The results are shown in Table 1 below.

[0042] Table 1 The results of three different methods of measuring the eggshell glue film of white shell and brown shell eggs

[0043]

[0044] Table 2 The rank correlation of the results of three different methods for measuring the protective film of white shell and brown shell eggshell

[0045] white shell egg △Tw~△Ew △Tw~△Rw △Ew~△Rw Rank Correlation (100%) 99.2 93.6 93 brown egg △Tb~△Eb △Tb~△Rb △Eb~△Rb Rank Correlation (100%) 96.6 94.2 94.7

[0046] (Note: △Tw, △Ew, △Rw respectively represent the opacity, color difference and reflectance difference of t...

example 2

[0051] Example 2: Take yellow, red, blue, white and pink cardboards with different colors but the same material, operate according to the above test steps and calculate the opacity change ΔT and color difference value ΔE of each colored paper respectively, the results are shown in figure 1 . ( figure 1 Among them, a, b, c, d, and e are five pink cardboards of yellow, red, green, white, and pink, respectively, and ΔT1, ΔT2, and ΔT3 are the opacities of the same color cardboard coated with three different solubility dye solutions, ΔE1, ΔE2, and ΔE3 are the color difference values ​​of the same color cardboard coated with three dye solutions with different solubility)

[0052] Depend on figure 1 It can be seen that △E varies greatly after the same concentration of MST glue coating blue is applied to different colored papers, and the change trend of different concentrations of the same colored paper is consistent, indicating that △E can only be used to compare the quality of egg...

example 3

[0055] Example 3: Comparison of the quality difference of different varieties of eggshell rubber protective film

[0056] 30 Dwarf chicken pure line and 30 Bailaihang eggs from the experimental chicken farm of China Agricultural University, and 30 Beijing duck eggs from a duck farm in Beijing. Use the above method to calculate the ΔT of the eggshell rubber protective film at the same time, and follow the above test steps Carry out the operation and calculate the opacity change ΔT (see figure 2 ).

[0057] Depend on image 3 (The overall comparison of the quality of the plastic film of various poultry eggs) The coloring of the plastic film shows that the quality of the plastic film of Peking duck is obviously better than that of chicken, which shows that there are great differences in the quality of plastic film between different species. However, the naked eye cannot accurately judge which type of rubber protective film has better quality. From the distribution of opacity,...

Abstract

The invention discloses a method for evaluating the quality of eggshell colloidal protection membranes with different colors. The method comprises: measuring the change of an XYZ color space by usinga spectrophotometer before and after an eggshell colloidal protection membrane is stained with a MST colloidal protection membrane blue, converting the XYZ color space into a RGB color space through aformula, finally converting into opacity, and evaluating the quality of the eggshell colloidal protection membrane by calculating the change of the opacity before and after the staining of the eggshell colloidal protection membrane, wherein the higher the change of the opacity before and after the staining of the eggshell colloidal protection membrane, the better the quality of the eggshell colloidal protection membrane, and the smaller the change of the opacity before and after the staining of the eggshell colloidal protection membrane, the worse the quality of the eggshell colloidal protection membrane. According to the present invention, the method has characteristics of simple operation, low cost and short detection time, and can be generalized to various poultry eggs with colloidal protection membranes, such that the variety with the excellent colloidal protection membrane and the variety with the poor colloidal protection membrane quality can be hybridized so as to select the variety with the excellent colloidal protection membrane quality, reduce the bacterial invasion chance on poultry eggs, and prolong the storage and fresh-keeping time of poultry eggs.

Description

technical field [0001] The invention relates to the use of opacity algorithm of chromatics, in particular to a method for evaluating the quality of eggshell glue protective films of different colors. Background technique [0002] In recent years, with the improvement of living standards, the demand for eggs is also increasing, but more food safety problems have followed. In 2010, a serious "egg crisis" broke out in the United States. Hundreds of consumers had symptoms such as fever, diarrhea, nausea, vomiting and abdominal pain after eating eggs contaminated with Salmonella. In our country, especially in summer when bacteria are easy to breed, poisoning incidents caused by bacterial pollution are not uncommon. [0003] In the United States, Japan, Australia and other countries, egg cleaning and disinfection and graded sales have been implemented. At present, there is no egg cleaning model in my country. Generally, eggs are collected directly from chicken farms and transport...
