Why Does White Rice Boil Over? Rice is the staple food for more than half of the world’s population. Farmers have cultivated the grain for centuries. It is one of the most important crops in some countries, such as India and China. People use rice to produce rice wine, sake, and popular alcoholic beverages in Japan. You can eat rice either boiled or cooked with other ingredients to form dishes like: Pilafs Risottos Paella Many types of rice vary by shape and color according to their origins: A white long-grained from Thailand Brown short-grained from Nepal Black medium-grain from Italy Red/purple short-grain from California. Today, my main focus is on white rice. Let me answer some questions below. Why Does White Rice Boil Over? White rice boils over because of the shape and size of the pot you are using. A tall, narrow pot will make it boil over unless you reduce the heat and stir often. In fact, for every inch (2.5 cm) of pot height, you need to reduce the heat by 10° F (5° C). So, if you’re using a 2-inch-tall (5-cm-tall) pot, turn on the burner just high enough to keep the water simmering. Stir rice frequently during boiling. This allows any dry grains on top to get wet. Because of this, they won’t stick together as they cook and form clumps near the surface. That way, you’ll avoid the dreaded boil-over. To prevent a boil-over when cooking white rice on top of the stove, use a wider pot. A wider pot will create less chance of its contents rising above the surface level. That is, if they’re stirred too vigorously or if any grains stick together as they cook near the surface. The space around a grain of rice expands during cooking. So if you accidentally mash it into something that sticks together, the rice will have room to expand and won’t cause a boil-over. A wider pot also has another advantage. It’s easier to see what’s going on at the bottom of the pot during cooking. This is because there are fewer shadows from the sides of the pot above it. That is especially important if your stove has to weaken flame power. Rice edges and extinguishes itself in a wide pot. This creates unattended boiling, an invitation to disaster. Why Is My White Rice Bubbling? You're white rice bubbles because there are still pockets of water trapped within your sticky grains. So, if we look at what’s happening on the molecular level, you see that these water molecules are at a much lower temperature than the rest of the rice. As this is an unstable situation, they will soon move to a region of higher energy or heat. And when these pockets of steam expand and burst outwards, it causes the rice to bubble. How long will my white rice keep bubbling? Although your rice may still appear to be bubbling after it has cooked, most of the hot steam will die down on its own accord. That is within one or two minutes at most. This means that if you want your perfect serving of steaming white rice waiting for you upon arrival at the table, then you should keep cooking. This will ensure that most of the water has already evaporated by cooking them out of the oven. This prevents any further bubbling in your rice as you serve it to your guests. Should You Wash Lundberg Rice? No. It would help if you did not wash Lundberg rice. This is because the manufacturer advises against it. They say it could cause discoloration of grains and spurs to form on the surface and an uneven cooking time. Should we still rinse our Lundberg Rice, though? Let’s look at its nutritional values: The sodium content in 1 cup of uncooked Lundberg Brown Rice is 144 milligrams The potassium content is 6 percent of the daily recommended value The calcium content is 8 percent, and the iron content is 3 percent of the daily recommended value. However, if you get concerned about your health, you can go ahead and wash the rice. In this case, you will destroy Lundberg rice goodness. Some people reported that they got stomach ache when they cooked the rice without washing. Yet, this is a small percentage. So, if you haven’t experienced any health issues with uncleaned Lundberg rice, you can continue cooking it as per the manufacturer’s instructions. Does Lundberg Rice Have Arsenic? Yes, Lundberg rice boasts arsenic.The company has been testing for arsenic in their rice for the past five years. The average level of inorganic arsenic in their rice over this time is 93 parts per billion (ppb), or 4.2 micrograms per serving. Despite the low levels of arsenic measured, the company has gone to great lengths to educate consumers about its products. They reassure you that their products are safe. To separate themselves from other foods that have come under scrutiny by researchers and the media due to heightened awareness surrounding food safety issues. Lundberg created an online resource center called “Food Facts.” This is where they share information with consumers on various aspects of the food industry. They provide information on the various pesticides and herbicides used to grow their rice, as well as arsenic levels. The website also explains that most of the arsenic in our food comes from natural sources not related to any human activity. They explain that there are safer ways to remove arsenic than using a chemical process. They have experimented with a new way of removing it via fermentation instead of chemical treatment. In addition, they explain how they test for other common pesticide residues such as: Dieldrin DDT Aldicarb Atrazine They also give consumers information on how to read an ingredients label. This helps consumers not to purchase foods made with these substances. “Food Facts” is definitely for their customers. But the layman quickly understands the information they share. You can read these fact sheets and feel reasonably confident that Lundberg rice does not contain any harmful levels of arsenic. They reaffirm this confidence in their product through visible quality control measures. The measures get implemented at every production level. In short, Lundberg appears to be a company with nothing to hide regarding its food safety standards. Their website informs consumers of the process used to test for pesticides, herbicides, and other contaminants commonly found in rice. They also include how they go about testing for arsenic. They even share an example of how to read an ingredients list. So, you can make good purchasing decisions following the ingredients list. A recent (2007) test conducted by Dr. David Plunkert of the FDA found that 100% of independently tested samples of rice purchased from grocery stores contained arsenic. The arsenic levels boosted levels ranging from one to six parts per billion. Why Does My Rice Smell Musty? Your rice smells musty because you left it too long in storage, causing humidity to get to the grains. Most people store their uncooked rice in airtight containers. The containers, unfortunately, prevent access to fresh air. When you store food items like rice in airtight containers without allowing it to breathe, moisture from both the inside and outside builds up around them. Although you might not see or feel this moisture with your bare hands at first, you’ll start noticing a damp smell once you open the container. This can linger for a while until you cook the rice again and it gets cleaned. It may incline you to want to throw out that batch of rice. But try this first: place your container outside or in a well-ventilated area; open it up once every week for about five minutes. You’ll notice that the smell will dissipate. Alternatively, keep the container partially open at all times instead of closing it completely. This way, moisture from both inside and outside can escape, letting no excess humidity come in. It’s also recommended that you store your containers on off-white paper plates or newspapers. Not only do they provide better ventilation than plastic bags, but they’re also less likely to lead to sticking or to food poisoning. This only applies to some types of rice because the grains come from different places and have different characteristics. For example, while long-grain rice varieties like basmati grow in high altitudes with lower humidity. Short-grain varieties like jasmine grow in humid regions where the weather is warm year-round. Thus, they absorb moisture more quickly from their surroundings than others would. As always, cook the rice right away after opening it. If left for too long on a plate or bag, they’ll continue absorbing water. They will also become mushy by the time you get around to cooking them. Small amounts of oxidization won’t be harmful, but allowing them to soak up too much moisture may form mold. This won’t happen to all rice types, but only those that absorb lots of moisture from their surroundings. And as long as the process is gradual enough (as opposed to you leaving out your bag of rice for weeks on end). It probably won’t be obvious until you cook them and notice an off-putting smell. Always store uncooked grains like rice in airtight containers that allow them some fresh air. If possible, keep them outside or in newspapers where they’ll get better ventilation than plastic bags can provide. In most cases, this will ensure that your rice won’t develop a musty smell during storage. Does Raw rice Mold? Yes! Raw rice molds and attracts bacteria when stored for long. I base this answer on the science of microbiology. Raw rice will become contaminated with bacteria and mold spores. The longer you store raw rice, the more likely it is to grow mold. Food storage experts do not recommend consuming foods more than a few days old. That is in warm environments where bacterial growth can occur. The growth of molds on foods like raw rice occurs because they need water or moisture to germinate and develop into large colonies of cells. Aspergillus fungi grow on your food every day, whether you can see it. These spores can carry deadly diseases such as: Pulmonary infections, Allergic reactions and other illnesses. Consuming raw rice or drinking water contaminated by molds can cause serious disease that requires immediate medical attention. Most people with allergies to foods react to proteins on the surface of molds and certain types of fungi. People with asthma may also develop respiratory problems when breathing in mold spores that become airborne when food is being prepared. Exposure to aspergillus mold can cause: Shortness of breath Wheezing Tearing eyes Coughing Scratchy throat Vomiting Nausea Dizziness The danger of consuming raw rice is even more problematic for children. This is because they do not have a fully developed immune system like adults, who are less likely to become affected by bacteria and toxins naturally present in the environment. The bottom line is that raw rice can become contaminated with bacteria and mold because of various factors, including exposure to heat, air, and moisture. Suppose you want to protect your family’s health. In that case, I recommend you avoid eating foods like raw rice. This is because they can provide an excellent food source for bacterial growth or aspergillus molds. In turn, this could have serious consequences for your overall well-being. Conclusion As you can see, many factors can affect the way your rice cooks and tastes. Some of these things may be easy to identify, like how long it’s cooked or if you used too much water, but others might not be so clear at first glance. If you ever notice anything strange about the consistency of your rice (or any other food), do a quick internet search for it. There is always someone who has experienced a similar situation before and already figured out what went wrong with their cooking process. We hope this article helped answer some questions about white rice boiling over. Why does my white rice bubble up when I cook it, should you wash Lundberg Rice, does Lundberg Rice have arsenic? Etc.
