Problems solved by technology

However, the ripening of bananas by ethephon is easy to cause the bananas to rot and affect the color of the bananas, thereby affecting the commodity value of the bananas
Moreover, due to the difference in pH value of the ripening environment, it is difficult to quantify the decomposition of ethylene, which makes it difficult to control the ripening process and effect

Embodiment 1

[0016] Example 1 Effect of 4-P-PDOT treatment on banana fruit ripening

[0017] The harvested banana fruits were divided into two groups: normal ripening group and 4-P-PDOT treatment group.

[0018] Normal ripening group: put the banana fruit in a culture room at 25°C until it matures naturally, observe and record the peel color of the banana fruit on day 0, day 3, day 6, day 9, day 12, day 15, day 17 and day 19 The change.

[0019] 4-P-PDOT treatment group: Banana fruits were soaked in 30 μM 4-P-PDOT solution for 2 hours, and then placed in a 25°C culture room. 12 days, 15 days, 17 days, 19 days observed and recorded the change of banana fruit peel color.

[0020] The results showed that under normal ripening conditions, the banana fruit gradually changed from green to yellow after harvesting, reached a full yellow state at 15 days after harvesting, and black spots appeared at 17 days after harvesting. Under the condition of 4-P-PDOT treatment, the banana fruit gradually c...

Embodiment 2

[0021] Example 2 Effect of 4-P-PDOT treatment on banana fruit ripening

[0022] The experimental method is the same as in Example 1, except that the only difference is that the concentration of the 4-P-PDOT solution used in the 4-P-PDOT treatment group of the present embodiment is 100 μM, and the soaking time of the banana fruit in the 4-P-PDOT solution for 6h.

Embodiment 3

[0023] Example 3 Effect of 4-P-PDOT treatment on ethylene release and quality of banana fruit

[0024] Under normal maturation and 4-P-PDOT treatment (the treatment method is the same as in Example 1), samples were taken at time points of 0 day, 3 days, 6 days, 9 days, 12 days, 15 days, 17 days, and 19 days, and the determination Relevant physiological indicators (including banana fruit ethylene release, banana fruit firmness, etc., each treatment was measured 3 times at each stage).

[0025] Ethylene release from banana fruit: determined according to the instructions of the ethylene detector of Shenzhen Kernuo Electronic Technology Co., Ltd., each treatment was measured 3 times at each stage.

[0026] The hardness of banana fruit was determined according to the instructions of the hardness tester of Hangzhou Top Instrument Co., Ltd. Each treatment was tested 3 times at each maturity level.

[0027] Determination of banana fruit starch content: take 0.5g banana pulp, grind i...

Abstract

The invention belongs to the technical field of acceleration of fruit ripening, and discloses an application of 4-P-PDOT in acceleration of banana fruit ripening. The banana fruits treated by the 4-P-PDOT have increased endogenous ethylene release amounts, and turn yellow ahead of time; moreover, the hardness, the starch and the soluble sugar qualities of the treated banana fruits are not affected. The invention further provides a method for accelerating ripening of the banana fruits. The method comprises the following steps: soaking harvested banana fruits in a 4-P-PDOT solution for a certain period of time, air-drying the soaked banana fruits, and carrying out normal-temperature storage. Compared with existing methods for accelerating ripening of the banana fruits, the method is simple in operation, safe, effective, and free of damages to the qualities of the banana fruits; moreover, the method has practical and wide application values.

Description

technical field [0001] The invention relates to the technical field of fruit ripening, and more specifically, relates to the application of 4-P-PDOT in accelerating the ripening of banana fruits. Background technique [0002] Banana is one of the most important fruits and the fourth largest food crop in the world. Banana ripening is an indispensable link in the banana industry chain. Banana ripening techniques commonly used at home and abroad mainly include modified atmosphere method, fumigation method, ethephon method and so on. However, most of the banana ripening methods currently used have certain limitations, such as inconvenient operation, heavy workload, resulting in rotten bananas and affecting the quality of bananas. At present, the widely used banana ripening method is the ethephon method. The harvested banana fruit is soaked in ethephon solution, and ethephon decomposes to produce ethylene under the condition of pH=8, thereby promoting the ripening of banana fr...
