Prolonging expiration dates

Last time we discussed expiration date you were interested in looking into prolonging the expiration date by change to storage conditions from room temperature to refrigerator. Have you had any chance to investigate that further?

Once a standard is taken out of transpiration control packaging the evaporation rate will cause an increase in concentration of roughly 0.3% per year. This rate of evaporation can be reduced to around 0.1% or less by refrigeration. The expiration date is still one year.
