What is Polished Rice?
Polished Rice or White Rice is nothing but after the result of milling a traditional Paddy Rice whose upper husk with bran is removed and then polished for colour, texture, and taste.
How is Rice Polished?
Industrial Method of Polishing Rice
- The Rice paddy is weighed and then transported to the Rice Mill.
- This paddy is placed in a Grain Pit for pre-processing storage.
- Later on, the stored grains are moved to a large weighing machine through conveyors to Determine the Weight of the Raw material. It also helps in assessing the quantity loss in transportation.
- After weighing, the rice paddy is cleaned, the waste product is removed, and further weighing is carried out.
- The cleaned rice paddy is further moved to a large boiling container for partial boiling to make it softer. Again the weighing process is completed.
- It is then conveyed to a Heated Silo Storage for further moisturizing and dry heating.
- The paddy is again shifted from the Storage Silo to weight to know them before and after moisturizing and drying weight of the paddy grain.
- Rice paddy is then moved to the Milling Machine. Here, at the very first step, the paddy is passed from the “Destoner” for removal of husk and then the Sheller for cutting the upper bran layer of the Rice paddy.
- Further, the product is then passed through a “Whitener and Polisher” section, where the rice is polished to change its pale texture to shiny and white.
- Again the product is weighed.
- Now the rice is passed through Grader, which grades the rice according to the size.
- Now the full-size Rice and Broken Rice are collected separately and weighed.
- The broken rice and full-size rice is then stored in the Hopper section. Further, they are packed separately in bags with predefined weight.
- Finally, the shiny Polished White Rice is transported to the market dealers and later to the consumers.
Note: The removed husk in the processing is used for animal feeding. Whereas the powdered bran removed is also very useful like it is used for feeding fishes etc.
Small Scale Method of Polishing Rice / Domestic Method
- At a small scale, Race is polished and processed using “Rice Polisher Machine”.
- These machines use abrasion techniques to remove the husk from already steamed and dried rice paddy, and then side chopping is carried out to remove the upper bran coating.
- Further, it also has a section called “Whitener and Polisher”, where the rice is polished for smooth texture and white colour.
- Nowadays, multicoloured rice is also processed from these machines.
Difference Between Polished Rice and Unpolished Rice
|It is shiny and in general White in colour.
|Unpolished rice is traditionally Brown coloured.
|It has a smooth texture.
|Unpolished RIce is uneven.
|Rice Kennel is mostly devoid of upper bran coatings.
|Upper Bran layer of rice is retained on the whole even after the processing.
|Fiber quotient is very low in Polished white rice.
|Fiber is higher in unpolished rice ( whole grain ) as compared to White Rice.
|Polished white Rice is Easy to cook and takes less time.
|It takes longer to cook unpolished rice.
|It is Devoid of nutritional values on a large perspective due to excessive processing.
|Unpolished rice Contains higher Nutritional value such as Iron, Magnesium, Zinc, Calcium etc.
|It Can lead to bloating, gastritis etc.
|It is good for the bowel system.
Nutritional Value in Polished Rice ( per 100g )
**The nutritional value may vary to some extent from manufacturer to manufacturer. Please check the package for real values. The above data has been roughly approximated using Indian and US recommendations for adults.
What is Single Polished Rice?
Well, you must have heard of single polished rice too.
In Single Polished Rice, only the uppermost thin layer of bran is removed along with the paddy husk rather than the whole chunk of bran from the rice kennel.
Thus, they retain a large chunk of fiber and nutritional value. You can think it to be better than Polished Rice and less nutritional than Unpolished Brown Rice.
What is Parboiled Rice?
One more type of rice processing is present, which is known as Parboiled Rice.
In this process, the rice paddy is soaked for a few hours and boiled partially along with the husk. Later they dried completely. This makes the upper shaft of the husk loosen up. Thus, it becomes easier to remove the upper husk without even hampering the top nutritional layer of bran.
Although this gives a rigid, translucent texture to the rice.
They contain more minerals and nutrition than the “Polished rice” and “Single polished rice”.

Is Eating White Polished Rice healthy
While processing the Polished white Rice, the essential bran minerals, nutrients, and fiber gets removed. So, the end processed product has very low nutritional value and is rich in starch.
Also, at the stage of polishing and whitening- several powdered elements are used like talc, bran powder, glucose etc.
Thus, if we compare it with unpolished brown Rice, Polished shiny Rice is way less healthy.
Consuming Polished Rice can also lead to gastritis. Also, since they are less in fiber, regularly consuming them in high proportions leads to bad bowel movements.
Since polished White Rice has a Glycemic Index of approximately 70, it can spike sugar levels in the body. So, people who have diabetes should avoid having Polished white Rice.
It is to note that brown sugar, although it dissolves slower, can also lead to a rise in sugar level in the body. They, too, should be consumed by a diabetic person only on the doctors/nutritionist advice.
Also, if you are more concerned about your diet and health, it’s always better to take advice from a dietitian.

Q.) Why is polished rice bad?
A.) Polished rice is not good for health as a large chunk of nutritional value is removed in the processing.
Q.) Is unpolished rice better than polished?
A.) Since Unpolished Brown rice incorporates all the minerals and nutrition (like iron, calcium, zinc etc. ), they are far superior to polished rice without enough nutrition quotient.
Q.) Which is the Best Rice for daily use?
A.) For daily consumption, if possible, one should try to have unpolished brown Rice or parboiled Rice. They are quite nourishing and healthy.
Q.) Do Indians eat lots of rice?
A.) Yes, India is just second to China in the production and consumption of rice in the world.

A.) It’s because eating rice at night can lead to an instant spike in blood sugar levels due to a high Glycemic Index ( 70 ).
Q.) How is rice polished?
A.) Rice is polished with the help of the Rice Polishing Machine.
Q.) What Does a Rice Polishing Machine Do?
A.) Rice Polishing machines remove the husk and upper bran layer of the rice kernel. Further, it whitens/polishes the rice grain.
Q.) How can you tell if rice is polished?
A.) Polished rice can be distinguished through its smooth texture and shiny whitish colour.
