Flavouring Agents in Food: Discover the Secrets in 2024

Introduction

More than 1200 distinct flavouring agents are used in food to add flavour or restore Flavors that have been lost or altered during processing. Hundreds of flavouring agents in foods are utilized to mimic natural Flavors.

In our kitchen, we typically use natural flavorings. On the other hand, the food and beverage industries use both artificial and natural flavoring agents for large scale production.

Nowadays, more and more consumers are searching for food and drink items with clean labels that are created with natural, identifiable ingredients. In today’s world it is important to know about ingredients used in processed foods and flavouring agents are one of them.

Whether you are a food technologist, home cook, chef or simply someone who wants to know about flavouring agents this article will help you to understand the role of flavouring agents in food.

How is flavour made?

Food comes in a variety of forms, flavors, and textures, and everyone of us has preferences based on the flavors of certain foods. The various sensations we experience from food products as a result of chemical interactions between the food and our sensory systems are known as flavors. Despite the fact that most of us only think of food in terms of its taste, both the senses of smell and taste contribute to its flavor.

Flavors are combination of aroma chemicals that are created for particular end-uses. The precise composition for flavors is confidential and belongs to the flavor supplier, or “flavor house,” as intellectual property. Based on sources flavour is categorized as Natural Flavors and Artificial Flavors. The flavorist can combine and create a flavor for a particular end-use application using hundreds of known aroma components at their disposal.

What are flavouring agents in food?

The substances which are used to give food, flavor and aroma are known as flavouring agents.

Different types of flavoring agents are:

• Natural
• Nature-identical Or Artificial flavoring agents
• Plant- or animal-based flavoring agents
• Process flavorings that take on flavor when heated; and smoke flavorings

What is flavour classification?

The FDA has defined Natural Flavors as ingredients which come from sources in nature, such as spices, fruits or vegetables.

Natural flavouring agents examples are:

• Herbs- mint                                       
• Spices- clove, turmeric, cardamon
• Aromatic Seeds- Cumin           
• Fruits- Lemon, Orange
• Vegetables- Onions, Garlic 

Artificial flavouring agents examples are:

• Monosodium glutamate(MSG)
• Nucleotides
• Maltol

How is artificial flavouring made?

In order to replicate a natural product, flavorists study the chemical composition of the original ingredient. After determining the molecular structure, flavorists use a variety of substances that match to the natural flavor’s flavor profile.

Advantages and disadvantages of flavouring agents

Advantages of Artificial flavouring agents:

Cost Effective

Artificial flavors can be created and produced by flavor engineers for much lower price than natural ones.

Meets Consumer Demand

The annual production of vanilla beans is insufficient to satisfy the demand for vanilla flavoring among consumers. Many popular flavors rely on natural materials that aren’t agriculturally scalable to meet global demand. Climate change affecting growing seasons and crop viability around the world, the bioavailability of natural flavors may place an importance on the ability to design alternatives safely.

Artificial Flavoring Is Safe

Artificial food flavors are monitored and tested from its creation to implementation in a final product. Sanitary conditions and strict storage requirements at manufacturing facilities ensure the safety of possible results.

Sustainable

In the production of natural ingredients, emissions caused by growing, processing and transporting them are more as compared to artificial flavors. Synthetic ingredients require less processing, less energy and a less production time.

Advantage of Natural flavouring agents:

Natural flavours are obtained by separating specific chemical component from natural sources, such as an essential oil from a specific fruits, nuts or vegetable.

A flavorist will use chemical component from a single or many natural sources to develop the flavor profile for a specific product. Mostly flavours are a combination of many different natural ingredients.

As it is obtained from natural sources it is safe and has no harmful effects.

Disadvantage

There is no disadvantage of using any natural flavouring agent in food.

Some people allergic to certain substances may have allergies. Example Natural flavours derived from common allergens like eggs or wheat.

In general, it is not found that artificial flavours cause allergic reactions. Like all other food additives, artificial flavours must pass different safety tests before being approved. Most natural and artificial flavours are made from the same chemicals and have a nearly same molecular structure
