A sunscreen that protects your skin from harmful UV rays, a preservative that increases the shelf life of fruits and vegetables and a molecular water filtration system are few of the several technologies on display at the Indian Institute of Technology (IIT), Delhi stall.

This year, the Foundation for Innovation and Technology Transfer, an organisation under the aegis of the IIT, has set up a stall to display the technologies developed by the faculty and researchers of IIT.

Officials claim these are cost-effective products and a major improvement over the ones currently being used for personal as well as industrial use.

Take the sunscreen. "It is at least four times more effective than the ones currently available," said Dr H.M. Chawla Head of IIT's chemistry department. The sunscreen protects the skin from UV-A and UV-B rays. "Most sunscreens available commercially only protect from UV-A rays," says Chawla. And there are no side-effects.

A newly developed preservative is better than its commercially available substitutes. Coat an apple with it and the apple won't rot at least for a month. "Even if you don't refrigerate it," says Rahul Srivastava .

Use it on a potato and the green spots that generally appear soon due to germination will not appear.  Other technologically superior productsare also on display.

All the products have already been tested. Chawla said these are now being displayed for business houses to take up the technology and start commercial production. "Several Indian and foreign companies have shown interest," he said.
