In 2017, there were reports of plastic rice being sold in markets in India, particularly in the states of Andhra Pradesh and Telangana. Consuming plastic rice can be dangerous to human health, leading to cancers, birth defects, immune system suppression, and developmental problems in children. While it is difficult to differentiate between real and fake rice by simply looking at it, there are several simple techniques to identify plastic rice.

What You'll Learn
The water test: real rice sinks, fake rice floats
The water test is a simple and effective way to identify whether rice is real or fake. Plastic rice tends to float on top of the water, whereas real rice will sink to the bottom and stay there. To perform the test, take a glass or bowl of water and drop a tablespoon of raw rice inside. Stir the mixture for a few seconds and then let it settle. If the rice floats to the top, it is likely to be made of plastic. Real rice will sink due to its density.
This test is especially useful as it is difficult to differentiate between real and fake rice by simply looking at or observing the rice. Plastic rice may have a shine that is not seen in normal rice, but this is not always a reliable indicator.
It is important to be able to identify plastic rice as it can be very dangerous to human health. Plastic is toxic and can cause endocrine disruption, leading to the development of cancers and other serious health issues. Consuming plastic rice could also lead to birth defects, immune system suppression, and developmental problems in children.

The oil test: real rice floats, fake rice sinks
The oil test is one of the ways to differentiate between real and fake rice. It is a simple and effective method that can help you identify plastic rice and safeguard your health. Here is how you can perform the oil test:
Preparing the Rice
Start by taking a small amount of rice, about a tablespoon or a handful, and place it in a bowl. This rice sample will be used for the oil test. It is important to use a clean bowl and dry rice grains for accurate results. Ensure that the rice is free from any debris or foreign particles that might interfere with the test.
Heating the Oil
Pour oil into a separate pan or container. The amount of oil should be sufficient to completely submerge the rice sample. Heat the oil to a high temperature. You want the oil to be hot but not smoking. Use a thermometer for accuracy if needed. The ideal temperature will depend on the type of oil used, but it is generally safe to heat the oil between 325-375 degrees Fahrenheit (around 160-190 degrees Celsius).
Adding the Rice to the Oil
Once the oil is hot enough, carefully add the rice sample to the pan or container. Be cautious to avoid any splashing or burning yourself. You can use a spoon or spatula to gently place the rice into the oil. It is important to ensure that each grain of rice is fully coated in oil. Stir the rice gently to ensure even coating.
Observing the Reaction
Pay close attention to how the rice reacts in the hot oil. Real rice will typically float to the top of the oil. Meanwhile, plastic rice will sink to the bottom of the container. The plastic rice may also form a layer or film on the surface of the oil due to the melting of the plastic. This melting point will vary depending on the type of plastic used in the rice.
After performing the oil test, you can determine whether the rice is real or fake based on its floating or sinking behaviour. If the rice floats and shows no signs of melting, it is likely genuine. However, if the rice sinks and creates a layer on the oil's surface, it may be an indication of plastic rice. It is important to note that the oil test is a simple method for preliminary testing, and further tests or laboratory analysis may be necessary for conclusive results.

The smell test: fake rice smells like burning plastic
The smell test is one of the simplest ways to identify plastic rice. Plastic is known to give out a peculiar smell when burnt, and this simple trick can help you identify if the rice is real or fake. Take a few grains of rice and burn them with a matchstick. If the rice is made of plastic, you will see the rice curling in and giving out a peculiar smell, similar to charred wood or formaldehyde, whereas real rice may turn black but will not give out the smell of burning plastic.
It is worth noting that rice can have microplastics, depending on the type of rice you buy. Studies show that people consume 3 to 4 mg of plastic for every 100 g of rice they eat, with the number jumping to 13 mg per serving for instant or pre-cooked rice. Washing your rice can reduce plastic contamination by 20 to 40%.
If you suspect that your rice has a plastic smell, it could be due to the storage container. Clear plastic bins that are not marked as food-safe may contain additives that can migrate into the ingredients. These can be phthalates or other petrochemical/organic compounds, which are as unsafe in food as gasoline.
Spoiled rice may also have a sour or musty smell, and it will be slimy or gooey instead of airy and fluffy. It may also have blue, black, or green mold spores. Throw out rice that exhibits any of these signs to avoid food poisoning.

The mould test: real rice grows mould, fake rice doesn't
The mould test is a foolproof technique for checking the quality of rice, but it takes a long time. To do this, simply boil the rice and leave it outside in a box for 2-3 days. If the boiled rice is made of plastic, it will remain unchanged and will not develop any fungus. However, real rice will grow mould if it is kept outside for such a long time at room temperature.
The mould test is similar to the water test, which involves adding a handful of rice to a bowl of water and stirring well. Real rice will sink to the bottom, while plastic rice will float. However, it is difficult to differentiate between real and fake rice by simply looking at it, so the mould test is a more reliable method.
Another similar test involves adding a few grains of rice to a bowl of hot oil. In this case, the plastic rice will submerge and go to the bottom of the bowl, while the real rice will float above. Additionally, the plastic rice will form a layer on top of the oil due to the melted plastic.
It is important to note that consuming plastic rice is extremely unhealthy and can lead to serious health issues such as cancer, birth defects, immune system suppression, and developmental problems in children. Plastic rice is made of synthetic or semi-synthetic organic compounds that are dangerous to human health. Therefore, it is crucial to take the necessary steps to avoid consuming this fake rice.

The shine test: fake rice has a shine that real rice doesn't
Plastic rice is a serious concern in India, with reports of fake Chinese rice being sold in grocery stores in Andhra Pradesh and Telangana. Consuming plastic rice can be dangerous to human health, as it is made of synthetic or semi-synthetic organic compounds. It is important to be able to identify plastic rice to avoid any adverse health effects. One distinctive feature of plastic rice is that it has a shine that real rice does not. Here are some tests to identify fake rice based on this characteristic:
The Shine Test:
The shine of plastic rice is one of the key indicators that differentiate it from real rice. While it may be challenging to distinguish between real and fake rice by appearance alone, the shine test, in combination with other techniques, can help confirm the presence of plastic rice. Here are some steps to perform the shine test effectively:
- Observe the rice closely: Examine the rice grains for any unusual shine or glossiness. Plastic rice may exhibit a noticeable shine that stands out from the natural appearance of real rice.
- Compare with authentic rice: To enhance your assessment, it is helpful to have a sample of authentic, uncontaminated rice for comparison. Place the suspected plastic rice alongside the authentic rice and look for any discrepancies in shine or overall appearance.
- Utilise different lighting conditions: Evaluate the rice under various lighting setups. Observe the rice in natural daylight, artificial lighting, and even dimly lit environments. The shine of plastic rice may become more apparent or exhibit subtle differences when viewed under diverse lighting conditions.
While the shine test is a valuable tool, it should be noted that other tests, such as the water test, burning test, and mould test, are also essential for comprehensive verification. Combining multiple tests will increase the accuracy of your identification and help ensure the safety of your food. Remember, if you have any doubts about the authenticity of your rice, it is always best to err on the side of caution and avoid consuming it.
