Examples
example 1
[0190] Example 1. Simulate the current method of modified atmosphere used in the United States to keep 4×450g of beef fresh, check the quality of the beef after 21 days of storage and test the changes of oxygen and carbon dioxide concentrations with the storage days. The results are shown in Table 1. figure 1 shown
[0191] Table 1 of the current mechanical atmosphere method oxygen & carbon dioxide concentration changes with storage days
[0192]
[0193]
[0194]
example 2
[0195] Example 2. The formulation of non-iron-based oxygen absorbing and releasing oxygen scavenger Ea and the combination formula of non-iron-based absorbing and releasing oxygen scavenger Ea and release agent Gb (Ea&Gb) combined formula (ratio of the two = 1:1) absorption and release characteristics Test, the results are shown in Table 9, Table 10, Figure 9, and Figure 10
[0196] Example 2Ea of the present invention non-iron-based oxygen-absorbing agent absorption-release characteristics table 9
[0197]
[0198] Example 2 of the present invention (Ea&Gb) combined formula (1: 1) absorption and release characteristics table 10
[0199]
example 3
[0200] Example 3. Select (Sz&Gb) combination scheme to keep fresh 450g pork, check the quality of pork after 21 days of storage and test the changes of oxygen and carbon dioxide concentration with the amount of medicine and storage days, see Table 11, 12, 13; Fig. 11, 12, 13.
[0201]Example 3 of the present invention (Sz&Gb) combined scheme fresh-keeping 450g pork characteristic data table 11
[0202]
[0203] Example 3 of the present invention (Sz&Gb) combined scheme fresh-keeping 450g pork oxygen absorption characteristic data table 12
[0204]
[0205]
[0206] Example 3 of the present invention (Sz&Gb) combined scheme 450g pork quality evaluation table 13 after storage 21d
[0207]
[0208] It can be seen from Figures 11 and 12 that:
[0209] (1) Carbon dioxide concentration of 4#5# (50~60%CO 2 ) remains stable; 3# carbon dioxide concentration (38%CO 2 ) showed a slow downward trend; 1#2# carbon dioxide concentration (20%~24%CO 2 ) decreased significantly ...
