Problems solved by technology

However, it takes a long time to prepare chitosan solution with this method, which is not conducive to the postharvest treatment of fruits and vegetables, especially the postharvest on-site treatment in fruit and vegetable production areas, and the surface viscosity of fruits treated with chitosan is large. Soaking in polysaccharide solution is not ideal for directly inhibiting fungal diseases of fruits

Embodiment 1

[0027] A method for improving post-harvest Newhall navel orange fruit storage and preservation effect, specifically comprising the steps of:

[0028] (1) Newhall navel orange post-harvest fruit pretreatment: the post-harvest fruit is selected, cleaned, sterilized and disinfected; wherein, sterilization is soaked in 0.5% sodium hypochlorite for 5 seconds;

[0029] (2) Post-harvest Newhall navel orange fruit soaking treatment: Soak the pretreated fruit in a joint solution composed of Cardozan and acidic electrolyzed water for 5 minutes, take it out, drain the water, and wrap it in a 0.015mm polyethylene film bag Packing, and finally placing the packed fruit in a relative humidity of 85% and a temperature of 18°C ​​for storage.

[0030] Among them, Kadozan is diluted 800 times before mixing with acidic electrolyzed water; the pH value of acidic electrolyzed water is adjusted to 2.0, and the effective concentration is 80mg L -1 , the oxidation-reduction potential is 1321mV; the d...

Embodiment 2

[0032] A method for improving post-harvest Newhall navel orange fruit storage and preservation effect, specifically comprising the steps of:

[0033] (1) Newhall navel orange post-harvest fruit pretreatment: the post-harvest fruit is selected, cleaned, sterilized and sterilized; wherein, sterilization adopts 0.5% sodium hypochlorite soaking for 10s;

[0034] (2) Post-harvest fruit soaking treatment of Newhall navel orange: Soak the pretreated fruit in the joint solution composed of Cardozan and acidic electrolyzed water for 10 minutes, take it out, drain the water, and wrap it in a 0.015mm polyethylene film bag Packing, and finally the packed fruit is stored under conditions of 90% relative humidity and 19°C.

[0035] Among them, Cardozan is diluted 600 times before mixing with acidic electrolyzed water; the pH value of acidic electrolyzed water is adjusted to 2.5, and the effective concentration is 90 mg L -1 , the oxidation-reduction potential is 1313mV; the diluted Kadozan...

Embodiment 3

[0037] A method for improving post-harvest Newhall navel orange fruit storage and preservation effect, specifically comprising the steps of:

[0038] (1) Newhall navel orange post-harvest fruit pretreatment: the post-harvest fruit is selected, cleaned, sterilized and disinfected; wherein, sterilization adopts 0.5% sodium hypochlorite soaking for 8 seconds;

[0039] (2) Post-harvest Newhall navel orange fruit soaking treatment: Soak the pretreated fruit in the joint solution composed of Cardozan and acidic electrolyzed water for 6 minutes, take it out, drain the water, and wrap it in a 0.015mm polyethylene film bag Packing, and finally the packed fruit is stored under conditions of 90% relative humidity and 17°C.

Abstract

The invention discloses a method for improving the storage and fresh-keeping effects of picked Neuron navel orange fruits. The method specifically comprises the following steps: (1) pretreatment of the picked Neuron navel orange fruits: selecting, cleaning, sterilizing and disinfecting the picked fruits; and (2) soaking treatment on the picked Newborn navel oranges: soaking the pretreated fruits in a combined solution consisting of cardolike and acidic electrolyzed water for 5-10 minutes, then taking out the soaked fruits, draining water, packaging the drained fruits with 0.015 mm polyethylene film bags, and finally storing the packaged fruits under the conditions that the relative humidity is 85-90% and the temperature is 17-19 DEG C. After being treated by the method disclosed by the invention, the infection index of the Neuron navel orange fruits can be effectively reduced, the storage quality of the picked fruits can be well maintained, and the storage resistance of the picked Neuron navel orange fruits can be improved.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, in particular to a method for improving the storage and fresh-keeping effect of post-harvest Newhall navel orange fruit. Background technique [0002] Newhall navel orange is a citrus species that has been developed in southern China in recent years. It is widely cultivated in Fujian, Jiangxi, Sichuan, Chongqing, Hunan, Hubei, Guangxi and other places in China. Newhall navel oranges are very popular because of their beautiful fruit appearance, good commerciality, and excellent meat quality. Newhall navel oranges mature intensively in November-December. Due to factors such as postharvest fruit physiological metabolism, aging and disease, Newhall navel orange fruits suffer from serious postharvest rot loss. Therefore, it is necessary to adopt necessary fresh-keeping technology measures for Newhall navel orange fruit to delay the physiological metabolism and aging of ...
