Rice is best stored as paddy because the husk provides some protection against insects and helps prevent grain quality deterioration. A safe or hermetic storage system prevents the grain from getting wet after drying and also gives protection from insects, rodents, and birds.
Rice can be stored for longer periods if:
- Moisture content is maintained at less than 14% for grain and 12% for seed;
- Grain is protected from insects, rodents, and birds; and
- Grain is protected from re-entering of moisture by rain or from the surrounding air.
A rule of thumb for seed is that the life of the seed is halved for every 1% increase in moisture content or a 5°C increase in storage temperature above recommended levels.
