I think as far as I'm aware that you shouldn't keep rice for longer than 24hrs after cooking, and that it's not suitable for freezing. Rice is apparently one of the biggest causes of food poisoning (so my DH tells me)... Sorry!
it will keep for 24 hours in the fridge(as long as you cool it quickly) and it freezes fine - we often store rissotto in the freezer for the kids (rice must be suitable for freezing or you wouldnt be able to buy frozen rice products). From the food standards agency:
It's true that you could get food poisoning from eating reheated rice. But it's not actually the reheating that's the problem it's the way the rice has been storedbeforereheating.
Uncooked rice can contain spores of Bacillus cereus, bacteria that can cause food poisoning. When the rice is cooked, the spores can survive. Then, if the rice is left standing at roomtemperature, the spores will germinate into bacteria. These bacteria will multiply and may produce toxins (poisons) that cause vomiting or diarrhoea. Reheating the rice won't get rid of these toxins.
So, the longer cooked rice is left at room temperature, the more likely it is that bacteria, or the toxins they produce, could stop the rice being safe to eat.
It's best to serve rice when it has just been cooked. If that isn't possible, cooltherice as quickly as possible (ideally within one hour) and keep it in the fridge for no more than oneday until reheating.
Remember that when you reheat any food, you should always check that it's piping hot all the way through, and avoid reheating more than once.
