What is 4-hydroxy-5-methyl-3(2h)-furanone?
4-hydroxy-5-methyl-3(2h)-furanone, also known as EHMF or strawberry furanone, is an organic heterocyclic compound classified as a flavoring agent. With CAS number 19322-27-1, this compound features a furanone ring structure with hydroxyl and methyl functional groups. It is structurally related to natural flavor compounds found in fruits, particularly strawberries, though it is typically synthesized for commercial use rather than extracted directly from fruit sources.
Common Uses
This flavoring agent is utilized primarily in the food and beverage industry to impart fruity, sweet, and strawberry-like flavor characteristics. Common applications include:
- Fruit-flavored beverages and soft drinks
- Yogurt and dairy products
- Confectionery and candy
- Baked goods and desserts
- Nutritional supplements and functional foods
- Ice cream and frozen desserts
The compound is valued for its ability to enhance fruity flavor profiles at low concentration levels, requiring only small amounts to achieve the desired sensory effect in finished products.
Safety Assessment
According to FDA records, there have been zero adverse events reported associated with 4-hydroxy-5-methyl-3(2h)-furanone and zero product recalls linked to this additive. The compound has not generated significant safety concerns in regulatory databases.
Toxicological data on this compound is limited in publicly available literature. Like many synthetic flavoring agents, safety assessments typically evaluate acute toxicity, chronic toxicity, genotoxicity, and potential reproductive effects. The limited adverse event history suggests that at levels used in food applications, this compound has not demonstrated notable toxicological effects in consumer populations.
The absence of FDA GRAS (Generally Recognized as Safe) status indicates that this additive has not undergone the formal GRAS notification process or received an affirmative GRAS determination. This does not necessarily indicate safety concerns; rather, it reflects the regulatory pathway chosen by manufacturers and the extent of safety documentation submitted to FDA.
Regulatory Status
4-hydroxy-5-methyl-3(2h)-furanone is not listed on the FDA's GRAS list, meaning it does not have the formal determination that experts generally recognize it as safe for its intended use. However, it may be used in foods under the Food Additive Amendment if it has been approved through the food additive petition process or under relevant regulations for flavoring substances.
In the European Union, this compound may be listed among approved flavoring substances under Regulation (EC) No 1334/2008, which establishes rules for flavoring agents in foods. Regulatory status can vary by country and region, and manufacturers must ensure compliance with local food additive regulations in markets where they distribute products containing this ingredient.
The compound's regulatory history shows no bans or restrictions in major regulatory jurisdictions, and it continues to be available for use in flavoring applications where regulations permit.
Key Studies
Published scientific literature on 4-hydroxy-5-methyl-3(2h)-furanone is relatively limited compared to more extensively studied food additives. Available research has focused on:
- Flavor chemistry and sensory characteristics of the compound
- Synthesis methods and industrial production
- Stability of the compound in various food matrices
- Comparative flavor profiles with natural fruit compounds
The lack of extensive toxicological literature may reflect both the limited use history and the general safety profile of synthetic flavoring agents in this chemical class. Additional safety data may exist in manufacturer submissions to regulatory agencies that are not publicly available.
