Abstract

The invention discloses a method for segmented degreening of citrus. The method comprises the steps of storage degreening, middle-stage degreening and later-stage degreening. By controlling temperature, moisture, time, ethylene concentration, ethylene flow rate and circulating air flow rate of each step, the problem that the concentration of ethylene varies for different steps in citrus degreening is solved, and the situation that fruit base rotting or fruit rotting caused by improper ethylene concentration is avoided; meanwhile, through proper internal circulation of air, uniformity of temperature and moisture of the surfaces of citrus and uniformity of ethylene concentration can be maintained, so that uniform and consistent citrus degreening is achieved, fruit color is fresh, bulk treatment can be achieved, cost is low, and taste is good.

Description

technical field [0001] The invention relates to the technical field of fruit ripening, in particular to a segmented degreening method for citrus. Background technique [0002] After the citrus matures, the body becomes soft and easily deteriorates, leading to rot during transportation and storage. For this reason, immature green fruits are usually picked, which is convenient for transportation and storage. After the greening treatment, they can be packaged and marketed. The chlorosis process of citrus requires a temperature of 28-29°C and a relative humidity of 90%-95%. Under these conditions, 3-5μL / L of ethylene can achieve the maximum chlorosis rate. Too high temperature or too low ethylene concentration is not conducive to chlorosis of citrus, and the volume fraction of carbon dioxide will also affect chlorosis. At present, citrus chlorosis treatment mostly adopts ethephon solution soaking or constant concentration of ethylene gas chlorosis. The former is convenient an...
