Understanding Food Thickeners: Categories and Their Global Demand

Food thickeners are essential ingredients used in the food industry to improve the texture, consistency, and appearance of products. They are especially important in sauces, soups, dressings, and desserts. Thickeners play a significant role in creating the perfect mouthfeel and viscosity for different food applications. The global demand for food thickeners is divided into various categories, based on their composition and functional properties. Let’s explore the different types of food thickeners and their usage based on their global demand percentage.

1. Starch-Based Thickeners (34% Global Demand)

Starch-based thickeners are the most widely used in food production due to their availability, cost-effectiveness, and versatility. They are derived from plants, including corn, potatoes, and tapioca. These thickeners work by absorbing water and swelling, which increases the viscosity of the mixture.

Common Starch-Based Thickeners:

• Corn Starch: The most common starch-based thickener, widely used in sauces, gravies, and puddings.

• Potato Starch: Often used for its smooth texture and ability to withstand high temperatures, it’s common in soups and stews.

• Tapioca Starch: A gluten-free option used in gluten-free recipes and in puddings.

• Wheat Starch: Derived from wheat, used in Asian food and certain sauces.

• Modified Starches: These are chemically treated to enhance their thickening properties in specific applications.

Benefits of Starch-Based Thickeners:

• Economical and easy to use.

• Commonly available and versatile for various types of food applications.

• Can be used in both hot and cold food preparations.

2. Protein-Based Thickeners (12% Global Demand)

Protein-based thickeners are derived from animal or plant proteins and help provide structure and viscosity to food products. These thickeners are particularly useful in dairy products, baked goods, and meat products.

Common Protein-Based Thickeners:

• Egg Whites: Used in meringues, custards, and certain sauces.

• Whey Protein: Derived from milk, commonly used in protein fortification and in dairy-based products.

• Soy Proteins: Often used as a vegan alternative in food thickeners for sauces and soups.

• Milk Proteins: Contribute to the thickness of dairy-based foods like puddings and creams.

• Collagen: Derived from animal tissues, it is used in gelling applications, particularly in gelatin-based products.

Benefits of Protein-Based Thickeners:

• Natural and provide additional protein content to the food.

• Useful for products that require structure, such as baked goods and gel-like textures.

• Can enhance the mouthfeel of certain products.

3. Hydrocolloid-Based Thickeners (45% Global Demand)

Hydrocolloids are a diverse group of water-soluble substances that form gels, improve texture, and provide viscosity in food products. Hydrocolloid-based thickeners are gaining popularity due to their ability to work in small quantities, making them very efficient.

Common Hydrocolloid-Based Thickeners:

• Gum Arabic: Used in beverages and confectionery for its gelling and emulsifying properties.

• Guar Gum: A popular thickener in gluten-free recipes, sauces, and salad dressings.

• Xanthan Gum: A common thickener in gluten-free baking, salad dressings, and beverages.

• Carrageenan: Often used in dairy products and plant-based alternatives, particularly for gel formation.

• Agar-Agar: Derived from seaweed, it is used to make firm gels, especially in vegan-friendly products.

• Others: Such as locust bean gum, pectin, and gelatin, used in various food products like jams and candies.

Benefits of Hydrocolloid-Based Thickeners:

• Extremely efficient in small quantities.

• Often provide gelling properties, ideal for confectionery and jelly-like products.

• Can work in both acidic and neutral pH environments.

• Often used in plant-based and gluten-free food products.

4. Other Food Thickeners (9% Global Demand)

Other types of thickeners include specialized ingredients that do not fall into the main categories above but still find applications in the food industry.

Common Other Food Thickeners:

• Sodium Alginate: A seaweed-derived thickener used in food processing and for gel formation.

• Carboxymethyl Cellulose (CMC): Commonly used in processed foods for its stabilizing and thickening properties.

• Hydroxypropyl Methylcellulose (HPMC): Often used in vegan and vegetarian food products as a thickener and emulsifier.

Benefits of Other Food Thickeners:

• Provide unique functionalities such as emulsification, stabilization, and water retention.

• Useful in niche applications such as plant-based food and processed foods.

Conclusion: The Rising Demand for Diverse Food Thickeners

The global demand for food thickeners is shifting as consumers and manufacturers alike search for products that offer convenience, texture improvement, and a wider variety of uses. Hydrocolloid-based thickeners lead the charge in terms of global demand due to their versatility and ability to work efficiently in low quantities. However, starch-based thickeners still hold a large share of the market, particularly in everyday food products like sauces and soups.

As food innovation continues, it’s likely we will see an increased focus on protein-based thickeners and other specialized ingredients, particularly as demand for plant-based and clean-label products grows.

Understanding the various types of thickeners and their functions can help manufacturers make better choices for product development, while consumers can enjoy foods that meet their texture and dietary preferences.
