RESEARCH PROJECT

The objective of this project was to develop a non-toxic, bio-degradable, ecofriendly and economical surface coating for extension of shelf life of mature Alphonso mango.

Post harvest losses in mangoes have been estimated in the range of 25-40% from harvesting to consumption stage. Present methods of minimizing post- harvest losses like low temperature storage, use of chemicals like waxes and modified atmospheric packaging have got limitations.

Calgon Bio-Organics Pvt ltd in collaboration with a premier scientific Institute, CSIR, has developed a polysaccharide based surface coating. This surface coating forms a semi-permeable membrane which creates a modified atmosphere, similar to control atmosphere used in storage but at low cost. It also forms a physical and chemical barrier against invading pathogens.

The technology developed by Calgon Bio-organics Pvt Ltd in collaboration with CSIR:

• Is edible, Non-toxic, Bio-degradable, eco-friendly product.
• Is bio- compatible and non-antigenenic.
• Is made from naturally occurring substances.
• Is washable.
• Is non-hazardous and easy to handle.
• Offers ease of application. Only dipping of Mangoes and drying is allowed.

The ingredients of the formulations are approved by US FDA and recognized as GRAS.
