What is Licorice Extract Powder?
Licorice Extract Powder (CAS Number 977070-62-4) is a concentrated flavoring ingredient derived from the roots and rhizomes of Glycyrrhiza species plants, most commonly Glycyrrhiza glabra. The extract is produced through solvent extraction processes that concentrate the plant's flavor compounds and active constituents, then dried into a powder form. The primary flavor-active compound in licorice is anethole, along with glycyrrhizin, which provides sweetness without caloric content.
Common Uses
Licorice Extract Powder is used as a flavoring agent in a variety of food and beverage applications, including:
- Confectionery products (candies, licorice candies, gums)
- Beverages (herbal teas, soft drinks, flavored waters)
- Tobacco products (in some jurisdictions)
- Pharmaceuticals and dietary supplements
- Baked goods and desserts
- Savory products (sauces, seasonings)
The ingredient's dual function as both a flavoring agent and non-nutritive sweetener makes it valuable in reformulation efforts aimed at reducing sugar content in food products.
Safety Assessment
Licorice Extract Powder has not received formal FDA GRAS (Generally Recognized as Safe) status, indicating that while it has a history of use in foods, it has not undergone the formal FDA GRAS affirmation process. However, licorice has been used traditionally and in foods for centuries across numerous cultures.
The FDA maintains zero recorded adverse events and zero recalls associated with Licorice Extract Powder in their database, suggesting a good safety profile in food use. Individual constituents of licorice, particularly glycyrrhizin, have been studied extensively in isolation. At typical food flavoring levels, licorice extract exposure is generally considered minimal.
It is worth noting that whole licorice consumption in large quantities has been associated with certain health concerns in clinical literature, primarily related to glycyrrhizin content and its potential effects on electrolyte balance and blood pressure with chronic, high-dose consumption. These effects are associated with medicinal doses of licorice root, not the trace amounts typically present in flavored food products.
The European Food Safety Authority (EFSA) and other regulatory bodies in Europe permit licorice extract as a flavoring agent, though some jurisdictions may impose restrictions on maximum levels or specific applications.
Regulatory Status
Licorice Extract Powder is permitted for use as a flavoring agent in the United States under FDA regulations (21 CFR § 182.20), though formal GRAS status has not been established. It is listed in the Code of Federal Regulations as a substance generally recognized as safe for its intended use as a flavoring agent.
Regulatory status varies internationally. The ingredient is approved in the European Union as a flavoring agent (FL 04.010), though EU regulations may impose maximum use levels depending on the specific food category. Different countries maintain varying requirements for natural flavor declarations and maximum permissible concentrations.
Key Studies
Most safety data on licorice relates to glycyrrhizin, the primary bioactive compound. Research has focused on:
- Absorption and metabolism of glycyrrhizin in the gastrointestinal tract, which is limited when consumed at typical food flavoring levels
- Historical use patterns and epidemiological data in populations with long-standing licorice consumption
- Comparative analysis of glycyrrhizin content in various licorice products and food applications
The gap between traditional use and formal GRAS designation reflects the ingredient's natural product status rather than identified safety concerns. Most available data comes from traditional use documentation and studies of licorice as a medicinal substance rather than as a food flavoring agent at typical use levels.
