During the whole storage period, the banana peaks of banana fruit due to low and high temperature damage occurred quickly at both temperatures of 10°C and 30°C. The equilibrium state was maintained for a short period of time. The plant respiration measurement system found that the storage condition was at 15°C. Under the MAP system, the state of equilibrium is maintained for the longest period of time. In other words, MAP storage of bananas under this temperature condition can avoid the premature emergence of respiratory peaks in banana fruits, thereby prolonging their shelf life.
Through the plant respiration measurement system data processing and analysis, it was found that the O2 concentration and CO2 concentration change trend with temperature changes can be consistent by the exponential curve of the respiratory measurement system, that is, as the temperature rises, the O2 concentration in the bag decreases exponentially. The concentration of CO2 increases exponentially. The temperature has a great influence on the size of the gas concentration in the equilibrium state of the system. In addition, in the plant respiration system test, the Ro and Rc of bananas rose with the increase of temperature; the O2 concentration in the bag decreased with the increase of temperature, while the increase of CO2 with the temperature indicated that the temperature of fruits and vegetables The effect of respiratory intensity is greater than the effect of temperature on the breathability of the film.
Temperatures affecting the respiratory intensity of fruits and vegetables can be analyzed on the plant respiration assay system, either by changing the enzyme's kinetic parameters of the respiratory intensity of fruits and vegetables, or by affecting the gas concentration in the map system. Therefore, it is of great significance to apply the plant respiration measurement system to grasp the influence of the MAP temperature of fruits and vegetables on the respiratory intensity of fruits and vegetables under equilibrium conditions and the concentration of gas in the bags.
Plant Respiration Measurement System to Measure Changes in Banana Storage Quality
The temperature, oxygen, and CO2 concentrations are the three main technical parameters of the MAP storage, interconnected and mutually restricted. Temperature is one of the most important factors. The plant respiration assay system determines that any storage in the fruit's respiratory metabolism above must be based on an appropriate storage temperature. Only at the right temperature and proper gas composition can fruits and vegetables achieve the desired MAP storage effect.
