There are several ways to identify plastic rice:
1. Check the texture: Plastic rice will have a smooth and shiny texture, unlike real rice which has a slightly rough texture.
2. Check the smell: Plastic rice may have a chemical or plastic-like smell when cooked, while real rice will have a natural and pleasant aroma.
3. Check the appearance: Plastic rice may appear unnaturally white or translucent, while real rice will have a more natural color and appearance.
4. Check the behavior when cooked: Plastic rice may not cook properly and may remain hard or have a strange texture when cooked, while real rice will cook normally.
5. Conduct a flame test: Burn a few grains of rice with a match or lighter. Real rice will burn and turn to ash, while plastic rice may melt or produce a plastic-like smell.
It is important to purchase rice from reputable sources and to be cautious of unusually cheap or suspicious-looking rice. If you suspect that you have purchased plastic rice, it is best to dispose of it and report it to the appropriate authorities.
