How to extend shelf life of fruits/Methods of Extension of shelf life of fruits 

 Using growth regulators; NAA, GA3. e.g. Pineapple.

 By covering with a polythene sheet. e.g. Banana.

 By hot water treatment. e.g. Mango.

 By covering with wax. e.g. Mango, Banana.

 By applying pesticides or fungicide. e.g. Litchi.

 Controlled on modified atmosphere storage. e.g. Pineapple, Papaya, Banana.

 By using hypobaric on the sub-atmospheric storage method.

 By using various chemicals. e.g. KMnO4, CaNO3, CaCl2. e.g. Guava.

 By using Ice ban cooling. e.g. Pear.

 By using evaporative cooling in cool chambers.
