[0028] Example 1:
[0029] The antistaling agent in this example is prepared per liter as follows: Dissolve 10 mg of N-(2-chloro-4-pyridine)-nitrogen-phenylurea (CPPU) in 20 ml of absolute ethanol, add an appropriate amount of water, and then Then add 10mg of gibberellin, and dilute to 1000ml with water to obtain the preservative.
[0030] Choose to harvest seven to eight mature bananas on a sunny day. Each combed banana is divided into individual fingers. Choose the bananas with no disease, insect pests and mechanical damage. Cut the flat fingers, wash and dry (25℃, drying time is about 0.5 ~1 hour); soak the dried banana with the above-mentioned preservative, soak for 10 minutes; place it in the room to dry (25℃, the drying time is about 0.5-1 hour), and then use a polyethylene plastic film bag (0.03mm) Pack and store at room temperature at 25℃ and relative humidity of 70-90%. After 90 days, the good fruit rate of banana fruits was over 95%, and the fruit quality remained basic...

[0031] Example 2
[0032] The preservative in this example is prepared per liter as follows: Dissolve 5 mg of N-(2-chloro-4-pyridine)-nitrogen-phenylurea (CPPU) in 20 ml of absolute ethanol, add an appropriate amount of water, and then Then add 10mg of gibberellin, and dilute to 1000ml with water to obtain the preservative.
[0033] Choose to harvest seven to eight mature bananas on a sunny day. Each combed banana is divided into individual fingers. Choose the bananas with no disease, insect pests and mechanical damage. Cut the flat fingers, wash and dry (25℃, drying time is about 0.5 ~1 hour); soak dried bananas with the above-mentioned preservative, after soaking for 5 minutes; dry indoors (25℃, drying time is about 0.5-1 hour), and then use polyethylene plastic film bag (0.03mm) Pack and store at room temperature at 25℃ and relative humidity of 70-90%. After 90 days, the good fruit rate of banana fruits was over 95%, and the fruit quality remained basically unchanged.
