Embodiment 1

[0016] A method for long-distance transportation and preservation of papaya, which adopts the following steps:

[0017] 1) Harvesting treatment of papaya: When the ripeness of papaya fruit is when the surface of the pericarp begins to change color until 1 / 4 of the pericarp turns yellow, it is harvested. After harvesting, select fruits without damage and no pests and diseases and put them into sodium hypochlorite with a concentration of 0.15g / L After sterilizing and cleaning in the disinfectant solution for 20 minutes, put it in clean water, rinse it, and place it in a ventilated and cool place at 10°C to dry;

[0018] 2) Fresh-keeping treatment of papaya: Fumigate dried papaya with 1-methylcyclopropene at a concentration of 3 mg / L for 12 hours in a closed space at 10°C, soak in preservative A for 4 minutes, remove and drain The surface soaking solution is placed in preservative B for 15 minutes, removed, dried, and stored in a ventilated and cool place at 10°C; the preservativ...

Embodiment 2

[0022] A method for long-distance transportation and preservation of papaya, which adopts the following steps:

[0023] 1) Harvesting treatment of papaya: When the ripeness of papaya fruit is when the surface of the pericarp begins to change color until 1 / 4 of the pericarp turns yellow, pick the fruit without damage and no pests and diseases and put it into sodium hypochlorite with a concentration of 0.20g / L After sterilizing and cleaning in the disinfectant solution for 15 minutes, put it in clean water, rinse it, and place it in a ventilated and cool place at 15°C to dry;

[0024] 2) Fresh-keeping treatment of papaya: fumigate the dried papaya with 1-methylcyclopropene at a concentration of 2 mg / L for 18 hours in a closed space at 15°C, soak in preservative A for 6 minutes, remove and drain The surface soaking solution is soaked in preservative B for 10 minutes, removed, dried, and stored in a ventilated and cool place at 15°C; the preservative A is composed of the following...

Embodiment 3

[0028] A method for long-distance transportation and preservation of papaya, which adopts the following steps:

[0029] 1) Harvesting treatment of papaya: When the ripeness of papaya fruit is when the surface of the pericarp begins to change color until 1 / 4 of the pericarp turns yellow, it is harvested. After harvesting, select fruits without damage and pests and diseases and put them in sodium hypochlorite with a concentration of 0.17g / L After sterilizing and cleaning in the disinfectant solution for 18 minutes, put it in clean water and rinse it, and place it in a ventilated and cool place at 12°C to dry;

[0030]2) Papaya preservation treatment: the dried papaya was fumigated with 1-methylcyclopropene with a concentration of 2.5 mg / L in a closed space at 12°C for 15 hours, then soaked in preservative A for 5 minutes, and then removed and drained. Dry surface soaking liquid, soak in preservative B for 12min, take out, dry, and store in a ventilated and cool place at 12°C; de...

Abstract

The invention provides a method for retaining freshness of pawpaw during long-distance transport and belongs to the technical field of fruit fresh-keeping storage. The method is characterized in that a sodium hypochlorite disinfection solution is used for rapidly disinfecting and sterilizing picked pawpaws, thereby inhibiting production of endogenous ethylene in the pawpaws; with a fresh keeping treatment way that fumigation by virtue of 1-methyl cyclopropylene is combined with soaking by virtue of a fresh keeping agent A and a fresh keeping agent B, fresh keeping effect on the pawpaws is obviously improved, maturation and senility of the pawpaws are delayed, hardness, crispness, color and flavor of the pawpaws are well maintained, disease resistance of the plants is effectively maintained, antioxidant strength of the plants is also enhanced, oxidation of nutritional ingredients is prevented, and nutrients of the pawpaws are protected from being destroyed; and in a transportation process, treated food packages are vacuumized and filled with nitrogen and then are used for packaging the pawpaws and put into a sealed shockproof box, so that the overall freshness and quality of the pawpaws are greatly improved, rotting and physical damage produced to the pawpaws in a long-distance transport process is avoided, and high quality of the pawpaws is maintained.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping and storage of fruits, in particular to a method for long-distance transportation and fresh-keeping of papaya. Background technique [0002] Papaya belongs to the perennial shrub or small tree of the genus Papaya in the family Rosaceae. It is a fruit tree widely planted in tropical and subtropical regions. , amino acids, a variety of inorganic minerals, vitamins, organic acids, protease, papaya alkali, etc., known as "Baiyi Fruit", papaya contains an enzyme that can digest protein, which is beneficial to the body's digestion and absorption of food. It has the effect of invigorating the spleen and eliminating food; papain and papain have the effects of resisting Mycobacterium tuberculosis and parasites and relieving spasm and pain, and can kill insects and fight tuberculosis; Nutrients to enhance the body's disease resistance. [0003] Papaya is a respiratory climacteric fruit. The release ...
