What You'll Learn
Rinse rice before cooking to reduce plastic contamination
Rinsing rice before cooking is a common practice in many cultures, and it offers several benefits, including reducing plastic contamination.
Washing rice before cooking helps remove surface starch, which can make the cooked rice sticky and clumpy. By rinsing the rice, you can achieve a fluffier texture and improve the overall taste. This practice is especially important for certain types of cuisine that prefer loose, individual grains of rice. For example, in Hispanic cooking, rinsing rice is common to achieve the desired "granocito" texture. Similarly, in Persian cooking, rinsing or soaking rice is essential to achieve the characteristic fluffy texture and longer grains.
Additionally, rinsing rice is an effective way to reduce plastic contamination. According to a study published in the Journal of Hazardous Materials, rinsing rice before cooking can reduce plastic contaminants by 20 to 40 percent. Australian researchers found that packaged rice may contain significant amounts of microplastics, with consumers potentially ingesting three to four milligrams of microplastics per 100 grams of rice. Therefore, rinsing rice is a simple way to minimize your exposure to plastic contaminants and improve the overall safety of your food.
The process of rinsing rice is straightforward and only requires a few extra minutes and a deep bowl. Simply pour the dry rice into the bowl, cover it with water, and use your hands to move the rice around. Drain the water and repeat this process until the water runs clear. This method helps remove any unwanted contaminants, including heavy metals, dirt, dust, debris, chemicals, and even small bugs that may have found their way into the rice during processing or storage.
While rinsing rice has its advantages, it is worth noting that it can also remove some beneficial nutrients. Therefore, it is a matter of personal preference and depends on the specific requirements of your dish. However, when it comes to reducing plastic contamination and achieving the desired texture and taste, rinsing rice before cooking is a recommended practice.

Perform a water test: real rice sinks, fake rice floats
There have been persistent rumours of "plastic rice" being sold in Africa and elsewhere, driven by viral videos showing bouncing rice balls. However, food safety agencies have found little to no evidence to support these claims. Nevertheless, if you want to stay cautious and check your rice for plastic, one effective method is to perform a water test.
The water test is simple and can be done at home. Take a glass or bowl of water and add a spoonful or a handful of rice. Stir the mixture for a few seconds and then wait for about 30 seconds to a minute for the water to settle. If the rice is real, it will sink to the bottom due to its density. On the other hand, fake rice made of plastic will float to the surface. You may see some dirt or debris floating, but all rice grains should eventually sink if they are real.
It is important to note that real rice may sometimes float due to surface tension or other factors, so it is recommended to repeat the test a few times to ensure accuracy. Additionally, this test may not be effective if the fake rice is made of a mixture of edible starches or other materials that can sink in water.
While the water test is a useful tool, it is not the only way to identify plastic rice. Other methods include a microwave test, a boiling test, a fungal test, and a fire test. The microwave test involves combining equal parts rice and water in a microwave-safe bowl and cooking it. Fake rice will form a thick layer of melted plastic on the surface, while real rice will absorb the water and fluff up. The boiling test involves boiling a handful of rice and checking for a thick layer of plastic material on the surface. The fungal test involves storing boiled rice in a bottle for a few days; if the rice is fake, it will not be affected by fungus. Lastly, the fire test involves burning a handful of rice; if it smells like burning plastic, it is not safe to eat.
By performing these tests, you can ensure that your rice is safe and free from plastic contamination. While the existence of plastic rice may be a myth, it is always better to be cautious and take the necessary steps to protect your health and well-being.

Microwave a small amount: fake rice will melt
While there is little evidence that plastic rice is a widespread problem, there are some methods you can use to test your rice and stay on the safe side.
One way to test your rice is to microwave a small amount of it. Combine equal parts rice and water in a microwave-safe bowl, or use your usual ratio for cooking rice. After microwaving, check for a thin layer of plastic. If the rice grains contract and melt, you probably have plastic rice.
Other ways to test your rice include the water test, the smell test, and the oil test. For the water test, pour rice into a bowl and cover it with water. Stir the water for a few seconds and let it settle. Real rice will sink to the bottom, while plastic rice will float. For the smell test, heat the rice and check if it releases a plastic smell. For the oil test, add a thin layer of rice to a hot pan of oil. If the grains contract and melt, you probably have plastic rice.

Avoid rice from China
There are a few ways to avoid consuming rice from China. Firstly, you can opt for rice that is locally grown or produced in a country other than China. Check the labels on rice packages to identify the country of origin.
Secondly, you can look for organic rice options, as organic farming standards typically prohibit the use of synthetic pesticides and fertilisers. China's rice production is known for its heavy use of pesticides and fertilisers, so opting for organic rice reduces the likelihood of consuming rice from China.
Thirdly, you can source your rice directly from trusted farmers or suppliers who can guarantee their rice is not from China. This may involve buying from specialty stores or local markets where you can inquire about the rice's origin.
Finally, you can choose to consume alternative grains or pseudocereals like quinoa, millet, or buckwheat, which are not typically associated with Chinese production.
It is worth noting that the rumours of "plastic rice" from China have been largely debunked, with food safety agencies finding little evidence to support these claims. However, there have been instances of Chinese companies producing rice substitutes made from potatoes, sweet potatoes, and synthetic resins, which are passed off as premium rice grains. These substitutes are not made of plastic but are still misleading to consumers.
To summarise, avoiding rice from China can be achieved by choosing locally grown or organic rice, sourcing rice from trusted suppliers, or opting for alternative grains. Being an informed consumer and staying updated on the latest food safety news can help ensure you make the best choices for your health and align your purchases with your values.

Avoid instant rice, which has higher plastic levels
Instant rice is a convenient option for many, but it's important to be aware of its potential drawbacks. Research has shown that instant rice contains significantly higher levels of plastic contamination compared to uncooked rice.
University of Queensland research found that humans consume approximately 3 to 4 milligrams of plastic for every 100 grams of rice, but this number jumps to 13 milligrams per serving for instant rice. That's almost four times the amount of plastic!
The reason behind this significant increase in plastic content is thought to be due to industrial processing. The study also suggested that washing rice with water can help reduce plastic contamination.
To minimize your exposure to plastic contamination, it is advisable to avoid instant rice or at least reduce its consumption. Opting for uncooked rice and properly washing it before preparation can be a healthier choice.
While the health effects of consuming microplastics are still being studied, it is important to recognize that exposure to these contaminants may pose potential risks. By being aware of the issue and making informed choices, we can reduce our exposure to plastic contamination and promote healthier dietary options.
