It is higher, and 10mmol/L effects are better than when at 0-4 days, 5mmol/L effects were better than 1mmol/L and 10mmol/L, 6-8 days
1mmol/L and 5mmol/L, therefore, can prove that oxalic acid can suppress the reduction of eggplant fruit total phenol content by the above results.
Reference picture 5, it can be seen that Flavonoid Content changes over time presentation gradually increased trend, and Flavonoid Content
Change over time roughly the same under each concentration oxalic acid treatment, change is little, and each group is without obvious difference.
Reference picture 6, it can be seen that the trend of the content presentation entire lowering of anthocyanin, but the pattern of each test group
Plain glycosides water average content is also maintained on control group, and 5mmol/L and 10mmol/L groups will compared with 1mmol/L on the whole
It is high.Therefore, as can be drawn from Figure 5：Oxalic acid can suppress the reduction of eggplant pericarp Anthocyanin content, and fresh-keeping effect and oxalic acid
Concentration is related, when being less than 6 days storage period, 5mmol/L concentration oxalic acid solution best results, when being more than 6 days storage period,
10mmol/L concentration oxalic acid solution best results.
In a word, it can be proved with reference to Fig. 2-6 result of the test, oxalic acid treatment can effectively keep the various colors of eggplant pericarp
Stablizing relatively for element, extends storage period to realize to the overall Preservation Treatment of eggplant, and integrate various concentrations oxalic acid solution
Treatment effect is it can be found that its optium concentration is 5mmol/L.
