Plastic rice is a grain product made to resemble rice, usually made from broken rice and other cereals, fortified with micronutrients, and containing harmful chemicals. While food safety agencies have not found evidence supporting claims of plastic rice being passed off as real rice, the public has raised concerns about the possible flooding of the Nigerian market with this substance. This text will discuss several methods to identify plastic rice and protect oneself from its consumption.
Characteristics and Values Table for Identifying Plastic Rice in Nigeria
| Characteristics | Values |
|---|---|
| Water Test | Pour a tablespoon of raw rice in a glass of water and stir. If the rice goes to the bottom, it is real. If it floats at the top, it is plastic rice. |
| Mold Test | Boil the rice and leave it in a warm place for 2-3 days. If mold appears, the rice is real. If it doesn't, it is plastic rice. |
| Hot Oil Test | Drop some rice into a pan with extremely hot oil. If the grains contract and melt, it is plastic rice. |
| Fire Test | Burn a handful of rice with a lighter. If it smells like burning plastic, it is fake. |
| Observation | If the rice forms a thick layer at the top of the container during or after cooking, it is likely plastic rice. |
| Taste Test | Taste raw rice on the spot when purchasing. Plastic rice is thick and hard. |
| Bounce Test | If the rice holds its shape and bounces when rolled into a ball, it may be plastic. However, this is disputed, as properly cooked rice can also bounce. |
| Color Test | When molding a few grains of rice, if the powder is a bright white color, it is real. If it has a yellow discoloration, it is fake. |

Water test: Real rice sinks, plastic rice floats
While food safety agencies have yet to find evidence of plastic rice, there are some simple ways to identify it from the comfort of your home. One of the simplest ways to identify plastic rice is to perform a water test.
The water test is a simple and effective way to identify plastic rice. All you need is a glass of water and a tablespoon of the rice in question. Here's how you can perform the water test:
- Take a glass of cold water: Fill a transparent glass with cold water. This will serve as your testing container.
- Add a tablespoon of rice: Place a tablespoon of the rice you want to test into the glass of water. Using a measuring spoon ensures you have a consistent amount of rice for testing.
- Stir the mixture: Stir the rice and water gently for a few seconds. This helps to ensure that the rice is fully saturated and dispersed in the water.
- Wait and observe: After stirring, wait for about 30 seconds to let the mixture settle. Observe the surface of the water for any grains of rice that float. Real rice will sink to the bottom, while plastic rice will remain buoyant and float on the surface.
It is important to note that this test relies on the different densities of real rice and plastic rice. Real rice, being primarily made of carbohydrates and proteins, has a higher density than water and thus sinks. On the other hand, plastic rice, which may be made of synthetic materials or improperly processed broken rice mixed with other cereals, can have a lower density than water, causing it to float.
By performing this water test, you can quickly and easily identify whether the rice in question is potentially plastic or authentic rice. However, it is always important to use multiple tests in conjunction for more comprehensive results.

Fire test: Burn rice and smell for burning plastic
The fire test is one of the ways to identify plastic rice. Here is a detailed, step-by-step guide on how to perform the fire test:
Prepare the rice
Firstly, get a handful of rice grains that you want to test. It is important to note that this test involves fire, so ensure you take the necessary precautions. Always have a fire extinguisher or water nearby to put out the fire in case it spreads. Perform the test in a safe, open space, away from flammable objects and substances.
Ignite the rice
Using a lighter or any other ignition source, carefully ignite a few grains of rice from the handful. Be cautious to avoid burning yourself. You can use a pair of tongs or heat-resistant gloves to hold the rice grains while igniting them.
Observe the flame and smell the smoke
Once the rice grains are burning, pay close attention to how the rice reacts to the flame. Observe if the rice catches fire easily and how it burns. Synthetic materials, such as plastic, typically melt under high heat and produce a distinct chemical or plasticky odour. Listen for any unusual sounds during the burning process as well.
Examine the residue
After the rice grains have finished burning, carefully examine the residue left behind. Synthetic fibres often leave behind a hard, shiny, plastic-like bead. This residue may provide additional clues as to the composition of the rice.
Compare the results
Finally, compare your observations with the expected characteristics of burning real rice. Real rice, being primarily composed of carbohydrates and proteins, should exhibit different burning behaviour from plastic rice. Real rice is expected to burn more like plant-based materials, producing an odour similar to burning paper, leaves, or wood and resulting in flaky, ashy remains.
The fire test is a useful tool for identifying plastic rice, but it should be used with caution due to the inherent risks associated with open flames. Always prioritise safety when conducting this test.

Oil test: Plastic rice melts in hot oil
Although food safety agencies have not found evidence of plastic rice, there are concerns about its presence in Nigeria. Plastic rice is believed to be made from potatoes and synthetic resin, and consuming it can affect the endocrine system, causing hormonal changes and potentially leading to liver cancer.
One way to identify plastic rice is through the oil test. Here is a step-by-step guide:
Oil Test:
- Place a pan on the stove and turn on the heat to a medium-high setting.
- Wait for the pan to get hot, ensuring it reaches a temperature of at least 200 degrees.
- Drop a thin layer of rice into the hot pan of oil.
- Observe the rice grains carefully. If the rice is plastic, it will contract and melt, forming a layer of plastic on the sides of the pan.
- Real rice will not melt in hot oil and will instead fry or cook as expected.
It is important to note that the oil test is not the only method to identify plastic rice. Other tests include the water test, fire test, mold test, and boiling test. These tests involve observing the rice's behaviour in water, burning it with a lighter, checking for mold growth, and observing its behaviour during boiling, respectively.
While the existence of plastic rice in Nigeria remains uncertain, conducting these tests can provide reassurance and help protect yourself and your loved ones from potentially harmful substances.

Appearance: Plastic rice forms a thick layer at the top
Although food safety agencies have found no evidence of plastic rice, there are some simple ways to identify it. One tell-tale sign is the formation of a thick layer at the top of the cooking vessel. This is a result of the plastic melting and forming a layer on the surface.
The "fake plastic rice" saga has been a trending topic in Nigeria, with the NCS assuring Nigerians that they will uncover the people behind the importation of the potentially harmful product. While it may be challenging to differentiate plastic rice from normal or adulterated rice by sight, there are some simple tests that can be performed at home.
The water test is one of the simplest ways to identify plastic rice. Simply place a tablespoon of raw rice in a glass of water and stir. If the rice floats to the top, it is likely plastic rice, as real rice will sink to the bottom. Another test is to burn a handful of rice with a lighter. If it catches fire and emits a plastic burning smell, it is likely plastic rice.
It is important to be vigilant when purchasing rice and to perform these simple tests to ensure the product is safe for consumption. Plastic rice has been known to contain chemicals like phthalates, which can interfere with the hormonal and reproductive systems. While the exact origin of the plastic rice rumours is unclear, they began circulating on social media in China around 2010 and have since spread to other countries, including Nigeria.

Mould test: Plastic rice won't grow mould
While there is little evidence to support the existence of plastic rice, there are still concerns about its presence in Nigeria. Plastic rice is believed to be made from potatoes and synthetic resin, and it can allegedly cause serious health issues if consumed.
One of the ways to identify it is through a mould test. Here's how you can perform this test:
Mould test
Leave the boiled rice in a warm place for 2-3 days. If mould does not appear, the rice is likely plastic. Real rice will develop mould because it is affected by the weather and temperature, whereas plastic rice will not be affected by these factors.
Other tests
- Water test: Place a tablespoon of rice in a glass of water and stir. If the rice floats, it is likely plastic.
- Fire test: Burn a handful of rice with a lighter. If it smells like burning plastic, it is fake.
- Hot oil test: Add a thin layer of rice to a pan of hot oil. If the grains contract and melt, the rice is likely plastic.
- Microwave test: Combine equal parts rice and water in a microwave-safe bowl. Microwave for 3-5 minutes, then skim the surface. If there is a thick layer of melted plastic, the rice is likely fake.
These tests can help identify potential plastic rice, but it is important to note that food safety agencies have not found significant evidence of its existence.
