Embodiment 1

[0025] Embodiment 1 banana ripening method

[0026] Control group: domestic conventional ripening methods: (1) Harvest bananas according to routine, wash, select, grade and carry out fresh-keeping treatment, put them into plastic baskets with polyethylene fresh-keeping bags inside, (2) prepare 500ppm ethylene fresh-keeping bags with tap water Use the solution, open the mouth of the fresh-keeping bag, spray the banana fruit with a sprayer until the fruit surface is moist, then tie the fresh-keeping bag tightly and seal it, and place it at 20°C to accelerate ripening. After 12 to 24 hours, the bag must be opened for ventilation for 1 hour, and then once a day for 10 minutes, 30 minutes, and 1 hour to remove the accumulated carbon dioxide and water vapor in the bag.

[0027] Treatment group: (1) same as the control group, put it into a plastic basket with a polyethylene fresh-keeping bag inside, (2) use 0.05M citric acid-sodium citrate buffer solution with a pH value of 3 to 4 t...

Embodiment 2

[0029] Embodiment 2 mango ripening method

[0030] Control group: domestic conventional ripening method: (1) Harvest mangoes according to routine, wash, select, grade and carry out fresh-keeping treatment, put them into plastic baskets with polyethylene fresh-keeping bags inside, (2) prepare 1000ppm ethylene with tap water Use the solution, open the mouth of the fresh-keeping bag, spray the mango fruit with a sprayer until the fruit surface is moist, then tie the fresh-keeping bag tightly and seal it, and place it at 25°C to accelerate ripening. After 12 to 24 hours, the bag must be opened for ventilation for 1 hour, and then once a day for 10 minutes, 30 minutes, and 1 hour, in order to remove the accumulated carbon dioxide and water vapor in the bag.

[0031]Treatment group: (1) same as the control group, put them directly into plastic baskets without fresh-keeping bags, (2) replace tap water with 0.2M acetic acid-potassium acetate buffer solution with a pH value of 3-4 to...

Embodiment 3

[0033] Embodiment 3 tomato ripening method

[0034] Control group: The control group is domestic routine ripening methods: (1) Harvest tomatoes according to routine, wash, select, grade and carry out fresh-keeping treatment, prepare 100ppm ethephon solution with tap water, and put tomato fruits into the ethephon solution Soak for 1 minute, then put it into a plastic basket with a polyethylene fresh-keeping bag inside, tie the fresh-keeping bag tightly and seal it, and place it at 25°C to accelerate ripening. After 12 to 24 hours, the bag must be opened for ventilation for 1 hour, and then once a day for 10 minutes, 30 minutes, and 1 hour, in order to remove the accumulated carbon dioxide and water vapor in the bag.

[0035] Treatment group: (1) Same as the control group, (2) replace tap water with 0.06M malic acid and sodium malate buffer solution with a pH value of 3-4 to prepare 100ppm ethephon solution, add 0.05% Tween 20, soak for 1 Minutes, directly put into a plastic ...

Abstract

The invention discloses a fruit and vegetable ripener and application thereof. The fruit and vegetable ripener is prepared from an ethephon solution of 100 to 1,000 ppm prepared by a buffering solution with the pH value of 3 to 4; as the pH value of the prepared ethephon solution is still retained between 3 and 4, ethephon is more stable, and fruits can directly absorb ethephon; ethephon absorbed by the fruits can release ethylene in the fruits, so that a sealed pack or a sealed ripening warehouse for maintaining the concentration of ethylene in the surrounding environment is not required. By the use of the ripener for ripening, ripening can be realized in the producing area, so that the operating land of a wholesale market is greatly saved; a preservative bag is open or is not sealed completely, so that the trouble of ventilation every day is avoided, and the workload is greatly relieved; meanwhile, the phenomenon that the fruits are discolored non-uniformly due to high concentration of carbon dioxide caused by severely rotted fruits or sealing as the humidity of a frequently sealed environment is extremely high is avoided.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable fresh-keeping, more specifically, to a fruit and vegetable ripening agent and application thereof. Background technique [0002] Climacteric fruits, such as tomato, banana, mango, papaya, avocado, etc., are usually harvested when the fruit reaches physiological maturity, that is, when the volume and weight no longer increase, but at this time the fruit is still inedible and the peel is green. The pulp is hard, sour, and astringent, and it needs to go through a stage called "post-ripening" to reach an edible state with good color, flavor and taste. These fruits can be naturally post-ripened after being placed on the plant or at a suitable temperature after harvesting, but it takes a long time, the post-ripening is inconsistent, and the coloring is uneven, which affects market sales and causes many difficulties in management and on the site. , commercially often need to carry out artifi...
