Mono- and Diglycerides vs Monk Fruit Extract: which is worse?

What is Mono- and Diglycerides?

Mono- and diglycerides are emulsifiers derived from glycerol and fatty acids, most commonly sourced from soybean, palm, or sunflower oil. They are partial glycerides that exist between monoglycerides (one fatty acid chain) and diglycerides (two chains). They are chemically similar to fats but are not classified as trans fats even when made from partially hydrogenated sources.

What is Monk Fruit Extract?

Monk fruit extract is derived from the fruit of Siraitia grosvenorii, a melon native to southern China. Its sweetness (150–250 times that of sucrose) comes from mogrosides, particularly mogroside V, rather than simple sugars. It has been used in traditional Chinese medicine for centuries. The FDA granted GRAS status in 2010.

Documented risks

Mono- and Diglycerides: Generally recognized as safe at typical food levels. However, mono- and diglycerides can be derived from partially hydrogenated oils, meaning they may carry trace trans fats that do not appear on the trans fat label because they are classified as emulsifiers, not fats. Some researchers have noted this labeling gap. A 2019 study published in Lipids in Health and Disease noted potential concerns with industrial trans fatty acids in these additives. For most consumers, exposure is low, and regulatory agencies including FDA and EFSA consider them safe at permitted levels.

Monk Fruit Extract: Currently considered safe with no significant adverse effects reported in human studies. Animal studies have shown mogrosides to have antioxidant, anti-inflammatory, and possible anti-diabetic properties. No carcinogenicity, mutagenicity, or reproductive toxicity has been identified. Due to its relatively recent introduction as a food additive in Western markets, long-term human safety data are more limited compared to older sweeteners. Overall, the safety profile is favorable.
