Uncooked rice can be stored on the shelf in a tightly sealed container. The shelf life of brown rice is shorter than that of white rice. The bran layers contain oil that can become rancid. Refrigerator storage is recommended for longer shelf life. Cooked rice can be refrigerated for up to seven days or stored in the freezer for six months.
All cereals keep best in airtight containers that keep out moisture, dust and insects.
At home, a tightly sealed plastic bag is sufficient protection. Instant hot cereals keep up to one year in their original box, but a tightly covered container is better. Since wholegrain cereals are rich in natural oils, purchase containers that do not have a rancid odor. Store wholegrain cereals in tightly covered containers or sealed plastic bags in the refrigerator where they should remain fresh for 5 months. When stored at room temperature, they will stay fresh one month.
