| Cucumbers were selected as the research objects, and the changes of physical and chemical indexes of different
cucumber varieties under different temperature environments were analyzed, including water content, decay degree, weight
loss rate, respiratory intensity, soluble solids content, relative conductivity, chlorophyll content, titratable acid content and
flavonoid content. Three temperature environments of 6, 12 and 18 ℃ were set for the experiment. The results showed that
the decay degree and relative conductivity were the largest at the end stage at 6 ℃. The change of respiratory intensity of cu⁃
cumber was stronger than that of cucumber, and the flavonoid content of cucumber was stronger than that of cucumber. At
12 ℃, the rot rate was the lowest at the end stage, and the rot degree of dry cucumber was less than that of cucumber. The
chlorophyll content and titratable acid content changed the most. The change in weight loss rate was the largest at 18 ℃.
The soluble solids content of dry cucumber first increased and then decreased, and the soluble solids content of cucumber
decreased all the time. In summary, compared with 6 ℃ and 18 ℃, the storage quality of cucumber at 12 ℃ is the most stable and the storage time is the longest. |
