Abstract

The present invention relates to the technical field of fruit packaging and particularly discloses a non-refrigeration transportation, preservation and packaging method of dragon fruits. The method comprises the following steps: S1, washing: fresh dragon fruits are placed in pure water for ultrasonic washing; S2, soaking: the dragon fruits are soaked in a nutritional supplement preservative for 2-4 minutes, and then the dragon fruits after being soaked in the nutritional supplement preservative are taken out to be drained; S3, bagging: the drained dragon fruits are packaged into packaging bagsand an aqueous solution of the preservative and a bactericide is evenly sprayed on the dragon fruits; S4, aerating: mixed air is aerated in the packaging bags and the mixed air comprises the following components in concentrations: 3%-5% of carbon dioxide, 85%-90% of nitrogen and 5%-12% of oxygen; and S5, storing: a gamma-ray radiation treatment is used and the treated dragon fruits are then stored centrally in the packaging bags. The non-refrigeration transportation, preservation and packaging method can realize storage and transportation of the dragon fruits under normal temperature and effectively reduce transportation and preservation costs.

Description

technical field [0001] The invention relates to the technical field of fruit packaging, in particular to a non-refrigerated transport and fresh-keeping packaging method for dragon fruit. Background technique [0002] Dragon fruit, also known as red dragon fruit, dragon fruit, fairy honey fruit, jade dragon fruit. Cactaceae, the genus Tianchi. The fruit is oval, 10-12 cm in diameter, red or yellow in appearance, with green rounded triangular fronds, white, red or yellow pulp, and fruit with black seeds. [0003] Dragon fruit is rich in nutrients and has unique functions. It contains vegetable albumin and anthocyanins, which are rare in general plants, rich in vitamins and water-soluble dietary fiber. Dragon fruit is a cool fruit. Under natural conditions, the fruit matures in summer and autumn, and is sweet and juicy. [0004] Dragon fruit is rich in nutritional value and has a good taste, but mature dragon fruit is easy to deteriorate, so when long-distance transportation...
