What are Common Additives in Commercial Flour and are They Safe to Consume?
Commercial flour is widely used in our daily consumption of bread, pasta, snacks, and baked goods. Flour is made from cereal grains that undergo a milling process to remove the husk, bran, and germ to produce flour. However, to enhance the flour’s quality, shelf-life, and appearance, manufacturers use a variety of additives during the manufacturing stage.
Some of the common additives that are added to commercial flour include enzymes, bleaching agents, and preservatives. Enzymes are added to improve the flour’s stability, and to enhance the dough’s elasticity and texture. Bleaching agents are used to improve the flour’s color and to speed up the aging process. Preservatives are added to prolong the flour’s shelf life.
The question remains, are these additives safe to consume? The Food and Drug Administration (FDA) approves additives and regulates their use in food products. Before an additive is added to food, it is thoroughly tested to ensure that it is safe for human consumption. Enzymes that are used in commercial flour are derived from natural sources, and they are safe to consume. Bleaching agents are also generally recognized as safe by the FDA when used in small quantities.
However, some preservatives have been linked to health issues. For instance, potassium bromate, a preservative that is sometimes added to flour, has been shown to cause cancer in laboratory animals. As a result, the use of potassium bromate is banned in some countries, including the European Union and Canada.
In conclusion, most additives in commercial flour are safe to consume when used in small quantities. However, it is essential to be aware of preservatives that have been linked to health concerns and to choose flour products that do not contain these preservatives.

Introduction
Flour is an essential ingredient used in baking and cooking, making it one of the most important staples in a pantry. With the popularity of commercial flour, one might wonder about the presence of additives in these products. While these ingredients may enhance the texture, taste, and appearance of flour, many people are concerned about their safety. In this blog post, we will identify some common additives found in commercial flour and explore whether they are safe to consume or not.
What are Additives in Flour?
Commercial flour is not just made up of flour grains, but it may contain other components including additives. Additives are defined as any substance that is added to food intentionally. These might be ingredients that improve freshness, texture, taste, or enhance the appearance of the final product. Here are a few common additives found in commercial flour:
- Bleach
- Bromate
- Ascorbic acid (vitamin C)
- Amylase
- Malted barley flour
- Fungal enzymes
- DATEM
Bleach
Flour bleaching agents are added to flour to improve its baking quality and enhance its appearance. The bleaching process is performed with the help of agents such as chlorine or benzoyl peroxide. As a result, the flour becomes whiter and has a finer grain size. Although the American government regards bleach in flour as safe for human consumption, many consumers remain concerned about this additive.
Bromate
Potassium bromate can be used to increase the dough’s strength and reduce the baking time of bread. However, this ingredient has been known to cause cancer in rodents, and therefore its use is banned in some countries including India, the European Union, Canada, and the United Kingdom. In the United States, the FDA does not allow flour manufacturers to use potassium bromate in flour, although traces of it have been found in some bread products.
Ascorbic acid (vitamin C)
As a dough conditioner, ascorbic acid not only improves bread texture but also improves the nutritional value of baked goods. Although ascorbic acid has no adverse effects, most of us consume an adequate amount of vitamin C in our daily diets, making it redundant for manufacturers to add more into flour.
Amylase
Amylase is a natural enzyme found in flour and helps to break down the starches, resulting in better bread texture. While it is considered safe, some who are intolerant to gluten may experience adverse effects after consuming amylase. If you have never had any problems with gluten, this ingredient is safe to consume.
Malted barley flour
Malted barley flour contains natural enzymes that break down starches and protein in dough, allowing for better fermentation and a smoother texture. Strictly speaking, malted barley flour is a natural ingredient and is generally safe to consume.
Fungal enzymes
Fungal enzymes are used to break down the starches in flour, helping to improve the bread’s texture. With a few exceptions, most enzymes are safe to eat and consume. They are often used in flour blends to aid in the baking process.
DATEM
DATEM or diacetyl tartaric acid ester of monoglyceride is designed to improve the emulsification of fats and oils in bread dough. It is a generally safe-to-consume ingredient and is approved by the FDA. However, some people may have concerns about consuming any additive, even if it is deemed safe.
Conclusion
Commercial flour has additives to enhance its texture, taste, appearance, and shelf life. Some additives, such as bleach and potassium bromate, have aroused controversy regarding their safety. However, the use of most additives used in commercial flour is approved by regulatory authorities like the FDA. It is essential to consider the source of your flour and check the ingredient list to be sure of what you are consuming. However, the good news is that most additives present in commercial flour are safe to consume, and you can continue to enjoy baking without significant health-related concerns.

FAQs – What are common additives in commercial flour and are they safe to consume?
What are common additives in commercial flour?
There are many different types of additives that can be found in commercial flour. Some of the most common additives include:
- Enrichment additives: These additives include nutrients like iron, niacin, and thiamin that are added to flour to replace nutrients lost during the refining process.
- Preservatives: These additives are used to extend the shelf life of flour and prevent it from spoilage. Common preservatives used in commercial flour include calcium propionate.
- Improvers: These additives are used to enhance the texture, flavor, and overall quality of flour. Common improvers used in commercial flour include ascorbic acid and potassium bromate.
Are they safe to consume?
Most of the additives used in commercial flour have been approved by regulatory agencies like the FDA and are generally considered safe for consumption. However, some additives like potassium bromate have been linked to health concerns and have been banned in many countries.
If you have concerns about consuming commercial flour or additives, you may want to consider using alternative flour options like whole wheat flour, almond flour, or coconut flour, which typically have fewer additives.

What is Whole Wheat Flour?
Whole wheat flour is made by grinding whole wheat kernels into a fine powder. Unlike refined flour which only uses the endosperm of the wheat kernel, whole wheat flour includes all three parts of the wheat kernel: bran, germ and endosperm.
Benefits of Whole Wheat Flour
Whole wheat flour is known to have several health benefits:
- High in Fiber: Whole wheat flour is high in fiber which aids in digestion and keeps you full for longer durations
- Low in Fat: Whole wheat flour contains lesser fat than refined flour
- Rich in Vitamins and Minerals: It is a good source of vitamins B1, B3 and B5, and minerals like zinc and iron.
- Manages Blood Sugar: Whole wheat flour has a low glycemic index which makes it better suited for people with diabetes as it does not spike blood sugar levels.
Where to Buy Whole Wheat Flour?
You can find whole wheat flour in your local grocery stores or online. Make sure to read the label and check that the flour contains 100% whole wheat if you want to derive maximum benefits.
Conclusion
Whole wheat flour is a healthy alternative to refined flour with high fiber content, low fat and rich in vitamins and minerals. Incorporating it into your diet can help manage blood sugar and improve digestion.
