A brief description of the Corn Starch Production Process

Corn Starch Production Process
The process of separating the starch from corn is one which involves several steps and procedures.  The corn starch thus obtained is from the endosperm of the kernel and is used in the production of several foods and other items.  The main aim of the corn starch production process is to release the starch from the cell structure and that too by ensuring that the germ is not damaged. When the process is over, 4 main derivatives are obtained and they are starch, fiber, germ, and gluten.  The following is a brief of the corn starch production process:

1. Corn cleaning and steeping
This is the first stage of the process and is done to free the corn of all kinds of impurities.  After cleaning, the corn is soaked in water so that it doubles in size.  Now the gluten bond weakens and the starch is thus released.

2. Milling, germ separation and drying
The second stage of the corn starch production process is one in which corn is coarsely milled so that the germ is separated from the fiber, gluten, and starch.  This process takes place in two main steps and for this, two discs, as well as 2 germ separations hydro cyclones, are employed. The corn germ which is thus obtained has corn oil and is made to remove from the slurry, washed and then removed from the water.

3. Grit milling and fiber washing
Fine milling process takes place by a special kind of a mill that grinds the harder parts of the corn.  The starch is thus removed completely and fiber is kept coarse.  Now the grit milk which has fine as well as the coarse fiber is pumped and is made to go through starch extraction and counter fiber washing processes.  Now, what happens is that the washed fiber leaves the system and is removed from the water and dried.

4. Starch and gluten separation, starch washing
The 4th step of the corn starch production process is starch and gluten separation from the starch milk which is obtained from the previous step.  In this process, the starch left leaves the separator as the underflow whereas, on the other hand, the gluten leaves the separator as overflow. 

5. Gluten dewatering and drying
Now the next step is the concentration of gluten in the disc nozzle separator as heavy phase, followed by leaving of gluten through the nozzles.  After this, the resultant concentrated gluten is made to go through a centrifugal decanter before the drying process.

6. Starch dewatering and drying
The starch slurry obtained is now dewatered through rotary drum filters or peeler centrifuge.  Now the dewatered starch cake is made to go through drying equipment and dried.

Indian corn starch is believed to be of the highest quality in the world and companies like HL Agro are surely responsible for this. Corn starch manufacturer & exporter, HL Agro caters to the unique starch requirements of the worldwide markets.  If you wish to purchase bulk corn starch or any other corn derivatives, you can contact the company for the most superior quality possible.

The two of the most commonly used sesame seed varieties include  hulled sesame seeds  and unhulled sesame seeds. There is often a comparison done between these two varieties and for your reference, we have brought a few of the main differences between hulled vs unhulled sesame seeds . Descriptions Hulled sesame seeds   are those kinds of sesame seeds from which the outer covering or hulls have been removed during the manufacturing process. On the other hand, unhulled sesame seeds are those which have their husk or hulls intact and not removed. Macronutrients and calories There isn’t a lot of difference between hulled and  unhulled ses...

Native & Modified Starches for food formulations

Starches from different sources, even those extracted from less common corn varieties, offer a range of functionality and present several potential advantages. Starch and derivatives have emerged as the most promising environment friendly ingredients over the years, offering varied application benefits in both food & non-food industries. These cost-efficient functional ingredients tend to influence appearance, texture, taste and shelf life of the products. We all want foods and beverages with great mouthfeel and taste, but don't want to fill up with fat, calories and sugar. Product developers recognize that low-fat, high-fiber and low carbs are critical factors today for baked goods and snack formulations. Starches help manufacturers to address these challenges. Starch can be extracted from more than 50 types of plants and supports sauces, puddings, pie fillings and soups. But no two starches are created equal, and that’s good for bakery and snack product developers seeking to ...
