The capitalist mode of production is born when labor power itself becomes a commodity, bought and sold. It is a commodity with a unique quality: it creates more value than it costs; it produces surplus-value. This is the shortest possible definition of capitalism: production for surplus-value.
Rice and beans are inexpensive foods that can be stored for 30 years or more if properly packaged, making them good candidates for emergency preparedness food supply. You can store a mixture of beans or a mixture of different rice types, but you must store rice and beans in separate containers. While simple canisters and plastic bags work well for general use storage, long-term storage requires air-tight containers and moisture prevention to prevent food spoilage.
For home purposes, as Garrick Saito has stated, you can store rice in the fridge for quite a long period. Though the longer you keep it in the fridge the more you risk giving yourself food poisoning of some form. Also the quality of it will decline due to dehydration and natural decomposition. would say about 2-3 days. It will last longer than that, but a good amount of water will evaporate and the rice will dry out, making it no longer appetizing. You can try spritzing a little water over the top of your rice and throwing it in the microwave in an attempt to reviving it.
