Release Agents


What is a Release Agent?

Release agents are substances that aid the removal of food products from their molding or packaging. In the baking industry, release agents help remove baked goods from baking pans, moulds, tins, trays, conveyor belts or packaging. The most commonly used release agents are lipids such as oil and butter.1

High fat baked goods tend to be removed more readily from baking pans compared to their low-fat counterparts. The most common food release agents are:1

  • Fats and oils
  • Waxes
  • Emulsifiers (e.g lecithins and magnesium stearate)
  • Silicones
  • Flour and starches
  • Their combinations

Origin

Traditional release agents such as oil and butter have been used for centuries for the removal of baked goods from baking containers. The industrialization of baked products brought about the need for automation and the need for systems to help release the product and speed up production.

Today, a wide variety of release agents are used in the baking industry depending on the application, type of product, formulation, production process and desired shelf life of the product.2

Function

Release agents’ main function is to aid in the removal of baked goods from pans or packaging. These same substances often have other functions in the bakery system (e.g fats used for lubrication, aerating, and other functions).

Nutrition

Release agent’s nutritional contribution to baked goods is negligible.

Commercial production

The production and or synthesis of release agents varies with the type of agent.

Application

Release agents are used in the baking industry to improve the quality of the products and the production process of such products. Other benefits include: 4

  • Cleaner work environment
  • Reduction of undesirable build up in bakery wares and waste
  • Increasing bakery wares lifespan
  • Reduction of processing times
  • Reduction of cost by improving the quality of the released products
  • Efficient production process

Some considerations when choosing the right release agent for baked goods production:2,4

  • Method of application: release agents can be sprayed, dripped or brushed on the surface of the baking pan or tray. In industrial applications, automatic systems such as air-less spray for low viscosity substances or air-mix spray systems for high viscosity substances are commonly used. Smaller scale bakeries use more traditional methods such as brushing or spraying directly from the can.
  • Baked product formulation: high fat baked goods may require lower amounts of release agent.
  • Baking process: processing conditions (e.g temperature, mixing times, baking times) should be taken into account when choosing the right release agent.
  • Type of baking container: material, shape of container i.e. pan, tin or tray.
  • Shelf life of the product: release agents should withstand the natural deterioration reaction of the baked goods and must be oxidation resistant to avoid quality deterioration.

Regulations

In the US, the FDA established that release agents are considered production aids and must follow the CFR Title 21 Part 178.3860.5

In the EU, release agents are considered  production aids, and thus are regulated by the EU Commission Regulation No 1333/2008 on food additives.1
