i found some research about the frozen condition on the pizza. This time, i cant find it on the net. Instead, i went to the FAIR PRICE mart to check out the frozen condition of the pizza, specifically, Hawaiian pizza with mushroom.

IT need to be kept frozen of below -18 degrees celcius. it cannot refreeze after thawing. and has expiry date of 24 nov 07. since now is on the april, i guess it has shelf life of at least 6 months. need to research more on that.
