Chemicals are everywhere, even in the food that we eat every day. Chemicals in food are substances that are added intentionally or unintentionally during the processing, packaging, or cultivation of food. While some chemicals are natural components of foods, like vitamins and minerals, others are added for different purposes such as flavoring, coloring, or preserving. They play an important role in making our food safer, tastier, healthier, and more convenient.
But not all chemicals in food are good. Some chemicals may be harmful if consumed in large amounts. Hence it is important to understand the types and uses of chemicals in our food. In this article, we are going to learn some applications of Chemicals in food in our daily lives.
Real-Life Applications of Chemicals in Food
Some of the real-life applications of chemicals in food are as follows:
Chemicals as Preservatives
Preservatives are chemicals that are added to the food to prevent the growth of bacteria, yeast, and mold thus protecting its consumers from food-borne diseases. Preservatives not only reduce the risk of food spoilage but also maintain its freshness. These chemicals help to extend the shelf life of products thus reducing wastage of food. This allows us to enjoy our treats for longer.
Examples of chemicals used as a preservative are Sorbic acid, citric acid, sodium benzoate, Potassium sorbate, etc.
Chemicals as Flavor Enhancers
Chemical flavor enhancers are used to improve the taste and aroma of food products. Such chemicals intensify the taste of food and make our meals more flavorful and enjoyable thus adding that extra flavor/taste to our favorite dishes.
Examples of chemicals used as a food enhancers are Monosodium glutamate (MSG), Hydrolyzed vegetable protein (HVP), Yeast extract, etc.
Chemicals as Artificial Sweetening Agents
Artificial Sweetening Agents are chemicals added to sugar-free products to provide sweetness without adding any extra calories. These chemical agents are sweeter than sugar so only a small amount is added to achieve the required sweetness. Artificial sweetening agents are used in food items that are marked as sugar-free. Thus people suffering from diabetes who have to control their sugar intake can also enjoy sweet food items without affecting their health.
Some examples of artificial sweetening agents are:
- Aspartame: Aspartame is a low-calorie sweetener made from aspartic acid and phenylalanine.
- Saccharin: Saccharin is one of the oldest artificial sweeteners. It is a hundred times sweeter than sucrose and is used in diet sodas and other low-calorie products.
- Neotame: Neotame is derived from aspartame. It is used in many food items and soft drinks, including dairy products, desserts, and flavorings.
Chemicals as Antioxidants
Some foods turn brown when they are left open in the air. This happens because of a process called oxidation, which can make food go bad faster. Antioxidants help slow down this process, keeping our fruits, vegetables fresh for a longer time.
Examples of Chemicals used as Antioxidants are Vitamin C (ascorbic acid), Vitamin E (tocopherols), Citric acid, Beta-carotene, Butylated hydroxytoluene (BHT), etc.
Chemicals as Food Colorants
Chemical colorants, both natural and synthetic, are added to food products to enhance visual appeal, and maintain consistency. They are used in a wide range of processed foods, beverages, and confectionery products. Some of the examples of food coloring chemicals are:
- FD&C Red No. 40 (Allura Red): This red coloring agent is found in candies, soft drinks, and baked food.
- Chlorophyll: It is a green pigment found in plants. It is used to add green color to foods such as candies, ice creams, and soft drinks.
- Beta-carotene: This is a natural orange pigment found in fruits and vegetables like carrots, pumpkins, and sweet potatoes, used as a food coloring agent.
Chemicals as Emulsifiers
Emulsifiers are chemicals that are used in food production to create stable emulsions, which are mixtures of two or more immiscible substances, such as oil and water. For instance Oil and water-based ingredients like mayonnaise and salad dressings stay mixed together in foods because of emulsifiers. Emulsifying agents stabilize these mixtures, preventing separation and ensuring a smooth texture.
Examples of chemicals used as an emulsifiers are Lecithin, Soy Lecithin, mono and diglycerides, Gum Arabic, etc.
Chemicals for Nutrient Fortification
Nutrient fortification is the process of adding one or more nutrients to food items to make them healthier. This is mainly done for foods that lack nutrients, like grains, cereals, etc. Chemicals are used to fortify certain food products with essential vitamins, minerals, and nutrients to address nutritional deficiencies and promote public health.
Examples:
- Milk is often fortified with vitamin D.
- Breakfast cereals may contain added vitamins and minerals. These additions help in addressing nutrient deficiencies and promote overall health.
- Fruit juices like orange juice are fortified with calcium and vitamin D to increase their nutritional value.
