Food additives have been used for hundreds of years. They are added to food for preservatives and flavoring, to alter the texture, or to boost appeal to the senses. We do not know if a new additive is safe from the first time it is tested. That is why it is important to be aware of what additives are in common processed food items.

Please read the following information if you want to know what food chemicals are, how they are commonly used in food items and how to identify the chemical in food items.

What are common chemicals found in food?


There are many chemicals added to food in order to improve its taste, texture, and shelf life. Some of these additives are natural, while others are synthetic. Natural additives include salt, sugar, and spices, while synthetic additives include preservatives, flavorings, and colorings. Most processed foods contain at least one additive, and some contain several. Some common additives used in processed foods are listed below:

  • Salt: Used to enhance flavor and preserve food.
  • Sugar: Used to sweeten food and improve texture.
  • Preservatives: Used to prevent spoilage and extend shelf life.
  • Flavorings: Used to enhance the taste of food.
  • Colorings: Used to improve the appearance of food.
  • Monosodium glutamate (MSG) – Used as a food additive to enhance flavor
  • Acrylamide – a chemical that can form when starchy foods are cooked at high temperature, e.g. fried or roasted
  • Artificial food coloring – used to enhance the appearance of fresh and processed meat foods
  • Artificial sweeteners – Artificial sweeteners are chemicals (ingredients) that imitate the taste of sugar
  • Calcium sulfate – an additive used to add hardness to processed foods
  • Sodium Benzoate – a common food preservative to prevent spoilage

How many chemical additives are in our food?

There are an estimated 10,000 chemical additives in our food. The Food and Drug Administration (FDA) only regulates a fraction of these additives, and many of them are generally recognized as safe. However, some of these chemicals have been linked to health problems, such as cancer and endocrine disruption.

The most commonly found food additives include:

Preservatives – These prevent food from spoiling or growing bacteria. They can be natural (like salt) or artificial (like BHA), but they’re often used together so you’ll see multiple preservatives on the ingredient list. Some preservatives are banned in other countries but are still used here because they were grandfathered in before regulations changed.

Colorants – These make food look more appetizing by adding color to it. There is no evidence that this makes food taste better or has any health benefits! Some colorants have been linked to various health problems like allergic reactions and hyperactivity in children.

Flavor enhancers – These improve the taste by adding chemicals that simulate natural flavors in foods like butter or cheese. The problem? These chemicals aren’t regulated by the FDA so there’s no way to know exactly what’s in them!

BHA and BHT: These preservatives help prevent food from spoiling by preventing fats from becoming rancid. They are often added to meat products, like hot dogs and ham, as well as baked goods like bread and cookies. Some studies have shown that BHA may be linked to cancer and neurological damage when consumed in high doses over time. Studies also show that these preservatives can cause gastrointestinal irritation when consumed at high doses over long periods of time.

Sodium nitrite: This additive is used to preserve meat products such as hot dogs, salami, and bacon by preventing bacterial growth during processing. Sodium nitrite has been linked to a variety of health issues including cardiovascular disease and risk of cancer.

Sodium Benzoate: Sodium benzoate is used as a preservative for foods like juices and sodas. It also prevents mold from growing on foods that contain vitamin C (ascorbic acid). When sodium benzoate comes into contact with vitamin C, it produces benzene — a known carcinogen linked to leukemia. In one study, rats given sodium benzoate had increased levels of DNA damage after drinking orange juice containing sodium benzoate.

What harmful chemicals are in our food?

There are many harmful chemicals in our food, including pesticides, herbicides, and other toxic chemicals. These chemicals can cause serious health problems, including cancer and birth defects.

Pesticides are used to kill insects and fungus on crops. They can be absorbed through your skin or inhaled if you are near where they are being sprayed. Some pesticides have been found to cause cancer in animals or humans and some have been shown to affect the nervous system or cause reproductive problems.

Herbicides are used to kill weeds on crops before they grow out of control. These chemicals can be absorbed through your skin or inhaled if you are near where they are being sprayed. Some herbicides have been found to cause cancer in animals or humans and some have been shown to affect the nervous system or cause reproductive problems.

Antibiotics are used to promote growth in livestock and poultry by preventing bacteria from growing inside their bodies. These antibiotics can build up in meat when used at low levels for a long time period; this is called “sub-therapeutic use” (STU). This buildup may be harmful because it creates resistance to antibiotics that could otherwise cure infections caused by bacteria that have become resistant due to STU.

Why are food chemicals in food?


There are many different chemicals found in food. Some of these chemicals are present naturally, while others may be added during processing or packaging. Chemicals can be added to food for a variety of reasons, such as to preserve freshness, enhance flavor, or improve texture. While most food chemicals are considered safe, some may pose a health risk if consumed in large quantities.

Food chemicals are used in everyday life by everyone from farmers to chefs and bakers. They’re added to foods such as apple juice and soda pop to make them more appealing to consumers.

Food chemicals can also help preserve foods by killing harmful bacteria or preventing them from growing. Others help increase shelf life by preventing oxidation or causing fats or oils to become solid again after they’ve been melted down for use in cooking or baking.

Some food additives have been used for thousands of years without any negative health effects being reported, so it’s difficult to know whether they’re dangerous or not. However, many studies have been conducted on the safety of various additives — both natural and artificial — and their results have led many governments around the world to regulate their use in foods sold commercially.

What are the risk due to chemicals in food?

The risk of chemical additives in food is that they may be toxic or cause other adverse health effects. Some chemicals may also be carcinogenic.

Chemicals are used in food to make it last longer, to improve its taste and texture, and preserve its color. They are also used as preservatives, dyes, and flavoring agents (e.g., MSG).

Additives can be added directly to food during processing or added later during packaging processes. These can be natural or synthetic chemicals, but there is no distinction between them when it comes to safety regulations.

The main risk of additives is that they may be toxic or cause other adverse health effects. Some chemicals may also be carcinogenic (cancer causing). These risks depend on the amount of additive consumed at one time, the duration over which it is consumed, and whether there are other factors that increase an individual’s susceptibility to the effects of these substances (e.g., age).

How do you identify chemicals in food?

There are many ways to identify chemicals in food. One way is to look for additives. Additives are substances that are added to food to improve its taste, texture, or appearance. Food additives can be natural or artificial. Another way to identify chemicals in food is to look for food additives. Food additives are chemicals that are added to food to improve its taste, texture, or appearance. Artificial food additives are usually made from petroleum products and are not found in nature.

The best way to identify chemicals in your food is by reading the label. There are two kinds of labels on foods: mandatory and voluntary. Mandatory labels tell you how much fat and calories are in the packaged food, how many servings there are per container (usually 1), and whether there may be allergens present (such as wheat). Voluntary labels tell you more about the ingredients in the product than mandatory labels do. Voluntary labels often give a short description of what each ingredient does and where it comes from (for example, “natural flavor” or “cane sugar”).

How do you test for chemicals in food?

The most common method for testing the presence of chemicals in food is through the use of a food tester. This device is able to detect the presence of chemicals by measuring the electrical conductivity of the food. If the conductivity of the food is higher than that of a control sample, then it is likely that there are chemicals present in the food.

The most common type of food tester is a pH meter. This device measures how acidic or basic (or how alkaline) a substance is. It does this by measuring how much hydrogen ions are present in a solution. If there are more hydrogen ions than usual, then it can be assumed that there are more acids present in the solution than normal — which could be an indication that there are some types of pesticides present in your food.

Another type of chemical testing involves looking at certain types of proteins (like myoglobin), which can help determine whether or not there are any toxic metals present in your food. These proteins tend to bind with certain metals and make them visible under an electron microscope — which makes it possible for scientists to determine if these metals are present in their samples.

How do I know which food chemicals are in my food?

There are a few ways to find out which food chemicals are in your food. One way is to check the food label. The food label will list all of the ingredients in the food, as well as any food additives that are present. Another way to find out which food chemicals are in your food is to contact the manufacturer of the food product. The manufacturer should be able to provide you with a list of all of the ingredients and additives that are in their products.

The Food Label

When checking for artificial coloring agents on a food label, look for words like “artificial color” or “color added.” If some artificial coloring agents are not listed on the label, it does not mean that they are not present in the product — only that they were not included on the list of ingredients.

Manufacturer Contact Information

The manufacturer should also be able to tell you what other chemicals may be present in their products. For example, many manufacturers will include warnings about allergens such as peanuts or nuts in their products, so if there is an allergy warning on a package then there may be other allergens present as well.

What we should notice about the food chemical?


When we buy food, we should always check the label for any chemicals that may have been added. These chemicals can be harmful to our health and we should try to avoid them as much as possible. Some of the most common food chemicals are artificial sweeteners, preservatives, and flavorings.

Artificial Sweeteners

Artificial sweeteners are one of the most common food additives. They are added to many different types of foods because they make them taste better without adding calories or carbohydrates. Unfortunately, artificial sweeteners can have negative effects on your health. They have been linked to weight gain and diabetes, so it’s best to avoid them whenever possible.


Preservatives are used in many types of processed foods to extend their shelf life and prevent spoilage; however, these chemicals can also be harmful if consumed in large quantities over an extended period of time. Some common preservatives include sodium benzoate (E211), potassium sorbate (E202), sodium nitrite (E249), propyl gallate (E310), and ethoxyquin (E320), benzoic acid, potassium bromate. The FDA has approved these preservatives in small amounts; however, they may cause stomach upset when consumed in large quantities.


Flavorings can mean anything from MSG (Monosodium Glutamate), which is often used as a flavor enhancer in Chinese food, to food coloring made from petroleum byproducts like coal tar dyes or carmine (a red dye made from crushed beetles). Carcinogens are also found in many flavorings such as nitrate, and nitrites used to preserve meats such as hot dogs and bacon.


If you’re looking to buy some organic food items, it is important that you know the shelf life of the said food items. You should also be aware of the chemicals and ingredients used in each item. You can find these details on certain food websites associated with organic food products.
