The work aims to study the effect of perm-selective membranes of amine carrier on the quality of broccoli. With the perm-selective membrane as the packaging materials, and the pure LDPE membrane treatment, treatment of modified basement membrane with diatomite and natural placement as the control group, the above-mentioned membranes were stored at the room temperature, and the quality change of broccoli wrapped in all kinds of packaging materials was regularly measured. According to the change of mass loss rate, chromatic aberration, total soluble solid, hardness, browning, vitamin C and other indicators of the broccoli in various packaging materials during the storage, the fresh-keeping performance of perm-selective membranes prepared was evaluated. After the 9 days' storage, the mass loss rate, chromatic aberration, total soluble solid, hardness, vitamin C and other indicators of the broccoli packaged in the self-made perm-selective membranes were higher than those of the control group in question, but the browning was lower than that of the control group. The perm-selective membranes can effectively control the respiratory rate of fruits and vegetables by regulating the selective permeation of CO2 and O2 in the package, so as to prolong the storage period.
