Distilled Monoglycerides
Also known as: monoacylglycerols, E471, Distilled Monoglycerides
Overview
Distilled Monoglycerides (DMG) are purified monoacylglycerols derived from natural fats and oils, primarily through distillation processes. They are amphiphilic molecules, meaning they possess both hydrophilic and lipophilic properties, which allows them to reduce surface tension between oil and water phases. This characteristic makes them highly effective as emulsifiers, primarily used in the food industry to improve the texture, stability, and shelf life of products like margarine, spreads, and functional edible oils. Beyond their role in food technology, DMGs can also serve as carriers for bioactive compounds in emulsions and microemulsions, potentially enhancing the delivery and stability of these compounds. While extensively researched for their physicochemical properties and food applications, direct clinical research on their health effects as dietary supplements is limited. Their fatty acid composition, such as behenic acid-rich monoglycerides, can influence their crystallization and rheological properties.
Benefits
Distilled Monoglycerides primarily offer functional benefits rather than direct health benefits as a supplement. Their main advantage lies in their emulsifying properties, which can indirectly support the stability and delivery of other beneficial compounds. For instance, research indicates that DMGs can significantly improve the oxidative stability and antioxidant capacity of functional edible oils enriched with antioxidants, with some formulations showing up to a 7.5-fold increase in antioxidant capacity when combined with compounds like walnut extracts. This suggests a potential to enhance the bioavailability of phenolic antioxidants in enriched oils by creating stable emulsions. However, direct human health benefits from consuming DMGs themselves have not been conclusively established through clinical trials. The evidence supporting these effects is largely derived from food science and technology studies, focusing on their role in product formulation rather than their physiological impact on humans. There are no specific population-specific benefits identified, nor are effect sizes or clinical significance established due to the lack of human clinical trials.
How it works
Distilled Monoglycerides function primarily as emulsifiers, not as direct biological agents. Their amphiphilic nature allows them to position themselves at the interface between oil and water phases, reducing interfacial tension and creating stable emulsions. This physical property is crucial for stabilizing mixtures of immiscible liquids, such as oil-in-water or water-in-oil systems. When ingested, monoglycerides are metabolized by lipases in the digestive system into glycerol and free fatty acids, which are then absorbed. While DMGs do not have direct pharmacological targets, their emulsifying properties can indirectly enhance the absorption of co-administered lipophilic nutrients by improving their dispersion and stability within the digestive tract. They do not interact with specific biological pathways or body systems in a pharmacological sense, but rather facilitate the physical environment for other compounds.
Side effects
Distilled Monoglycerides are generally recognized as safe (GRAS) when used as food additives, and no significant toxicity has been reported. There are no documented common (greater than 5%), uncommon (1-5%), or rare (less than 1%) side effects associated with their consumption. No known drug interactions have been identified, and there are no established contraindications for their use. For special populations, there is no specific data, but standard caution is advised for individuals with known allergies to the source fats from which the monoglycerides are derived (e.g., vegetable oils or animal fats). Overall, the safety profile of distilled monoglycerides is considered very high based on their extensive use in the food industry over many years.
Dosage
The concept of a 'minimum effective dose' or 'optimal dosage range' for Distilled Monoglycerides as a dietary supplement is not established, as their primary role is functional within food formulations rather than as a direct health supplement. In food applications, they are typically used at low concentrations, generally ranging from 1% to 5% of the total formulation. There is no defined maximum safe dose, but they are considered safe at the levels commonly used in food products. Timing considerations are not applicable for their use. DMGs are typically incorporated into oil-in-water or water-in-oil emulsions. Their emulsifying properties can enhance the absorption and bioavailability of co-delivered lipophilic compounds. For optimal functional effects in food systems, DMGs are often combined with other emulsifiers, such as lecithin.
FAQs
Are distilled monoglycerides safe to consume?
Yes, distilled monoglycerides are widely used as food additives and are generally recognized as safe (GRAS) for consumption, with no significant toxicity reported.
Do they have direct health benefits?
No conclusive evidence supports direct health benefits from consuming distilled monoglycerides themselves; their main role is functional, primarily as emulsifiers in food technology.
Can they improve nutrient absorption?
Potentially, by stabilizing emulsions that carry lipophilic nutrients, distilled monoglycerides may enhance the absorption and bioavailability of these co-administered compounds.
Are there any known allergies?
Allergies to distilled monoglycerides are rare and, if they occur, are typically related to sensitivities to the specific source oils or fats from which they are derived.

(2010, 2012) investigated the crystallization and interfacial properties of behenic acid-rich monoglycerides. The research focused on the physicochemical effects of these compounds on fat crystallization and emulsion stability, providing insights into their role in influencing food texture and shelf life. The findings are technical and relevant to food science, but do not address clinical outcomes or human health benefits.

The research demonstrated a significant increase (up to 7.5-fold) in antioxidant capacity, suggesting that DMGs can improve the delivery and stability of bioactive compounds within emulsion systems. This is an experimental study and does not include human clinical data.

These studies suggest potential functional benefits in improving gut health and reducing pathogens in animals. However, these findings are preclinical and cannot be directly extrapolated to human supplementation or health benefits.
