Refined microcrystalline wax is a food excipient commonly used for various purposes in the food industry. Here's a breakdown of its properties, functions, and safety considerations:
What is Refined Microcrystalline Wax?
- Natural origin: Refined microcrystalline wax is a purified wax derived from petroleum or certain plant sources. The refining process removes impurities to ensure a safe and consistent product for food applications.
- Properties: It appears as a white or yellowish odorless and tasteless solid with a slightly greasy feel.
Functions of Refined Microcrystalline Wax in Food:
- Coating agent: One of the primary functions of refined microcrystalline wax is as a coating agent. It can be used to:
- Protect fruits and vegetables: A thin wax coating can help minimize moisture loss and extend shelf life of certain fruits and vegetables.
- Coatings in candies and chewing gum: It can provide a protective layer, control texture, and enhance gloss in some candies and chewing gum.
- Glazing agent: In some cases, refined microcrystalline wax may be used as a glazing agent for bakery products to give them a shiny appearance.
- Mold release agent: It can also function as a mold release agent in some food processing applications.
Safety and Regulations:
- Generally recognized as safe (GRAS): Regulatory bodies like the US FDA consider refined microcrystalline wax generally recognized as safe (GRAS) for use in food products at permitted levels.
- Dietary considerations: The amount of wax typically used in food coatings is minimal and not a significant source of calories or nutrients.
- Regulations: There are established limitations on the amount of refined microcrystalline wax that can be used in different food applications.
