How maida is made
When we think about the delicious foods we enjoy, many of them are made from maida, or refined flour. From samosas to burgers, maida plays a crucial role in our daily diets. But have you ever wondered how maida is made? In this blog, we will explore the complete process of maida production, shedding light on its origins and the steps involved in its manufacturing.

The Origins of Maida
Maida primarily comes from wheat, which is the same grain used to make the roti we consume daily. The difference lies in the processing method, which separates the parts of the wheat grain to yield pure maida. Understanding the structure of wheat is key to grasping how maida is produced. A wheat grain consists of three parts:
- Bran: The outer layer, rich in fiber and minerals.
- Endosperm: The middle part that contains carbohydrates and proteins, primarily in the form of starch and gluten.
- Germ: The innermost part, which is packed with vitamins and minerals.
During the production of maida, the bran and germ are removed, leaving only the endosperm, which is then ground into flour.
The Maida Production Process
The journey of maida begins in the fields, where wheat is harvested using a harvester. This machine separates the wheat grains from the chaff. Once harvested, the wheat is collected in bags and transported to the factory.
Step 1: Initial Processing
At the factory, the wheat is unloaded at the dumping or intake point. From there, it moves through a series of processes to ensure cleanliness and quality:
- Sampling and Testing: Samples of wheat are taken for laboratory testing to check moisture, protein, gluten, and mineral content.
- Cleaning Process: The wheat undergoes pre-cleaning to remove large impurities like ropes, plastics, and paper using a rotating drum sieve.
- Gravity Cleaning: The wheat is passed through a gravity cleaner that uses inclined screens to separate other grains and stems.
- Magnetic De-Stoning: A magnetic de-stoner removes ferrous metal pieces like nuts and bolts from the wheat.
Step 2: Final Cleaning
The wheat then goes through a vibro separator to eliminate any remaining small impurities. Following this, it is sent to a de-stoner, where air is blown from below to separate stones and heavier materials from the lighter wheat grains.
The Milling Process
After cleaning, the wheat is ready for milling. The milling process can be broken down into several key steps:
Step 1: Moisture Adjustment
The cleaned wheat is sent to a moisture measuring device, where its moisture content is assessed. If needed, water is added to increase moisture levels between 7% to 20%.
Step 2: Cracking
The wheat is then sent to a cracking mill, where it is cracked open rather than ground. This process separates the bran, germ, and endosperm into a mixture.
Step 3: Purification
This mixture is passed through a purifier, which uses a series of vibrating screens to sort the endosperm from the bran and germ. Hot air is blown from below to help lift the lighter bran and germ away from the heavier endosperm.
Step 4: Grinding
The endosperm is then sent to a roller mill where it is ground into semolina. This semolina is further processed until it reaches the desired fineness, which is generally between 10 to 100 microns.
Why is Maida Different?
A common question arises: if maida is made from wheat, why does it taste different from whole wheat flour or semolina? The primary reasons are:
- Absence of Bran and Germ: The removal of bran and germ means that the fiber and minerals that moderate carbohydrate taste are absent, leading to a more intense flavor.
- Particle Size: The particle size of maida is significantly smaller than that of wheat flour or semolina, which allows it to mix quickly with saliva, enhancing its taste.
Conclusion
The process of making maida is intricate, involving various steps from harvesting to milling. Each stage is designed to ensure the purity and quality of the flour that we use in our daily cooking. By understanding how maida is made, we can appreciate the effort that goes into producing this essential ingredient in our kitchens.
