The Best Method for Polishing Rice

Rate this post

Rice is one of the world’s most significant agricultural crops, and it provides a staple diet for more than half of the world’s population. Rice is so vital that there are hundreds of types available across the globe, each with its own nutritional value, taste, and features.

Polished rice is a phrase that few of us have heard of, which is unsurprising given that it conjures up visions of rice that is pricey, uncommon, and only accessible to a select few.

It couldn’t be farther from the truth. Polished rice is fairly common, and even if you haven’t heard of the precise name, you have almost certainly come across it. Simply defined, polished rice is white rice, and if you’ve ever eaten white rice, you’ve had polished rice.

So, what exactly is polished rice, and how do you get it?

How To Polish Rice?

To get polished rice, you may either purchase it at a shop, purchase a home rice polisher that polishes the rice for you at varied thickness levels, or do it by yourself by washing the brown rice and physically kneading it to bruise the rice grains. Hand polishing will not provide the same benefits as machine polishing, but it is an efficient way if you just want to soften and digest your rice.

What is Rice Polishing?

Rice polishing is the process of removing the outer coats of rice grains using a machine. This is the procedure that transforms filthy brown rice grains into polished, glossy white rice grains.

Although this procedure makes the rice more appealing and appetizing, rice polishing and milling are also responsible for removing the majority of the nutrients in rice.

Rice’s nutrients are largely focused on its outer layers. Fats, proteins, and vitamins are all concentrated at the surface, while starch is concentrated inside.

Many nutrients are taken away when the outer layers are removed, which is why white rice, a kind of polished rice, is thought to be less nutritious than brown rice, which is less processed.

Most commercial manufacturers, however, inject some of these elements back into the rice at some stage throughout the processing, so it is not fully nutritionally barren. Most health advocates, however, say that the natural and unprocessed nature of unpolished and less processed rice delivers more superior forms of health advantages.

Whichever side of the nutritional spectrum you fall on, it is an undeniable truth that white rice is the most widely eaten form of rice worldwide.

How Do I Get Polished Rice?

You can acquire polished rice by doing one of the following.

1. Buy Already Polished Rice

White rice, also known as polished rice, is commonly accessible in most supermarkets and comes in a variety of flavors. This is the simplest and maybe most cost-effective method of obtaining polished rice.

2. Buy a Rice Polishing Machine

A rice polishing machine designed exclusively for the house will enable you to polish your brown rice to various degrees of thickness and processing levels. This is quite important if you want to manage how much of the outer layers are removed, or the rice polishing ratio.

The rice polishing ratio may not be as significant when preparing rice for eating (although some foodies are fastidious about the precise texture and taste of the rice they use), but it is critical for people who drink or make sake.

Some high-end rice cookers will also have this feature, which will polish the rice for you.

3. Polish the Rice Yourself

Lastly, if you do not want to invest in a home rice polisher or a high-end rice cooker, or if you are one of those individuals who like DIY projects for the sake of science, you may polish your own brown rice.

True, it will not miraculously transform brown rice into white rice, but it will significantly improve digestibility and simplicity of cooking. In the next part, we will look at the basic procedure.

How to Polish Rice

This approach is a simple way to polish or prepare brown rice without using a rice polisher at home.

You may simply polish rice by following these steps:

  1. Using a measuring cup, calculate the amount of rice required. If you’re cooking your rice in a rice cooker, use the measuring cup that came with it.
  2. Put your rice in a metal strainer or colander over a dish. This step may be done in the sink for convenience.
  3. Moving fast, cover the rice with water and rinse and swirl the rice grains around for approximately 10 seconds. This is done to remove any dirt or contaminants detected on the surface of the rice. Remove the water.
  4. If the rice water is still unclean, repeat the rinse procedure 2-3 times more, but do it fast. Rice is inherently designed to absorb water when it comes into touch with it. Working slowly will cause the rice to absorb all of the unclean water, which is not what you want.
  5. Place the colander back in the bowl after washing and begin pressing and kneading the rice, pushing it around the colander or strainer. Consider it similar to softly caressing the rice grains. This is known as bruising, and it is the process that softens and breaks down the outer bran, allowing water to soak through. This causes the brown rice to absorb more water, making it softer and more digestible.
  6. Clean the rice twice and see how the damaged rice emits brown-colored water.
  7. Grab a handful of grains and massage them between your fingers. The surface should be rough. If it is still smooth, the rice has not been sufficiently crushed, and you should repeat steps 5 and 6.
  8. Again, this procedure should not take long and should only take you around 10 minutes.

Polishing rice in this manner will not turn brown rice into the gleaming white rice seen in shops, but it will make brown rice lighter, more digestible, and simpler to boil.

Polished Rice vs Unpolished Rice

Polished rice is just white rice that has had its outer hull, bran, and germ removed during the manufacturing process. Unpolished rice, on the other hand, is rice that has only had the inedible outer hull removed, leaving the bran and germ intact. Unpolished rice is something like brown rice.

Why Is Rice Polished?

Rice is polished for many purposes. The following are some of the benefits of polishing rice:

  • By eliminating part of the insoluble fiber, polishing rice enhances digestion.
  • Improves palatability
  • Enhances the taste and texture of rice
  • Improves hunger appeal: Shiny, silky white rice grains are seen as more enticing than rougher unpolished rice grains.
  • Polished rice cooks more quickly than unpolished rice.
  • Polished rice has a longer shelf life than unpolished rice because the lipids and proteins remain intact, but unpolished rice might become rancid much quicker.

On the other hand, there are several drawbacks of eating polished rice:

  • Nutrients are removed during the procedure. Even if it is enhanced afterwards, enriched foods are not regarded optimal from a whole foods standpoint since the nutrients included in it do not have the same health-supportive natural energy as intact, unpolished rice.
  • Since it is low in fiber and high in starch, it is not recommended for persons who are trying to control their blood sugar levels to eat excessive quantities of it.
  • It has a higher glycemic index, which raises the risk of developing diabetes.

What Are the Benefits of Unpolished Rice?

Most dietitians believe that unpolished rice, such as brown rice, is the healthier option for the following reasons:

  • Insoluble fiber content is high.
  • Includes nutrients such as vitamins and minerals that help the body’s important functions.
  • It has a lower glycemic index and does not produce blood sugar spikes.
  • Aids in weight loss
  • Less processed and more natural
  • Contains intact chemicals that aid in cholesterol management and the prevention of hypertension and other disorders.
  • Compounds with anti-cancer activity may be present.

The Philippine Rice Research Institute claimed in an email to us that brown rice or unpolished rice is preferable than white rice or polished rice in terms of health advantages.

Unpolished rice is high in fiber, healthy fats, protein, and B vitamins, which can lower the risk of cancer, diabetes, and heart disease.

Apart from the health advantages, the manufacturing of unpolished rice or brown rice saves manufacturers energy and fuel by eliminating the polishing and whitening procedures. This makes it more cost-effective and environmentally beneficial.

In general, unpolished rice is the best option in terms of advantages, although polished white rice has vital applications as well. I think polished rice may be part of a balanced diet as long as consumption is controlled and a variety of nutritious items are included.

I’ve Heard of Polished Rice in Relation to Sake. What is the Connection?

Sake is a Japanese alcoholic beverage that is primarily derived from fermented rice. Polished rice is essential here since it greatly influences the flavor of the sake.

The rice polishing ratio is a term used in sake-making and drinking circles. It is a value that indicates how much the rice has been polished, or how much of the outside bran has been removed. The percentage represents how much of the rice core remains after polishing.

A rice polishing ratio of 60%, for example, suggests that 60% of the rice core remains after 40% has been polished away. A lower value indicates that more of the outer layer has been removed, and they are often regarded as more premium and pricey owing to reduced yield.

You may be wondering why polishing is so crucial here. Since the outer layers include fat and protein, they may impart a strong and peculiar taste character to the sake. As a result, the cleanest tasting sake has more of the outer layers removed or a lower polishing ratio, and is typically more costly.

What is the Rice Polishing Ratio of Rice For Consumption?

So all of this discussion of rice polishing ratios brings us back to our polished rice for eating. Rice polishing ratios for normal consumption range from 90-92%, which indicates that just 8-10% of the outside bran is removed, preserving some of the beneficial components contained in rice.

Rice used to make sake is often polished to a ratio of 70-50%, or even less in certain situations.
