Can you provide information about baby corn to extend shelf life?

Question

My research work is using Modified Atmosphere Packaging to extend the shelf life of organic baby corn and I want some information about its chilling injury and suitable film. (A.W.)

Answer

Corn or baby corn is not chilling sensitive and should be kept as close as possible to 0°C.  Regarding MAP, oxygen concentrations in the range of 3-5% and carbon dioxide in range of 5-10% are conditions that are usually reported as beneficial to quality and shelf-life.  Below are some references on corn.  I doubt that conditions for baby corn would differ.

I hope this is helpful. – Marita Cantwell
