Hi Dr Faiza Quddus . I think you can use Bacterol and Snow Fresh, were compared to the standard metabisulphite treatment used by industry. Bacterol gave similar protection to sodium metabisulphite, while Snow Fresh showed potential as a substitute.See the link: http://era.daf.qld.gov.au/458/

Addition of lemon juice (antioxidants) reduces the pH on the surface of the banana and delayed the chemical reaction.

Vacuum packing the fruit reduces the amount of oxygen available.

Unfortunately, I am not for potassium metabisulphite.
