What is Rapeseed Oil, Hydrogenated, Superglycerinated?
Rapeseed oil, hydrogenated, superglycerinated is a chemically modified form of rapeseed oil (also known as canola oil). The additive undergoes two primary processing steps: hydrogenation, which adds hydrogen atoms to the oil's molecular structure to increase saturation and stability, and superglycerination, a process that introduces glycerol molecules to enhance emulsifying properties. The result is a pale yellow to off-white substance with improved functionality as a food ingredient.
Common Uses
This ingredient functions primarily as an emulsifier and stabilizer in various food applications. Emulsifiers are crucial in food manufacturing because they allow water-based and oil-based ingredients to remain uniformly mixed, preventing separation. Common products containing similar hydrogenated and superglycerinated oils include:
- Baked goods and pastries
- Margarine and spreads
- Confectionery products
- Sauces and dressings
- Processed meats
- Dairy-like products
The superglycerinated modification makes it particularly effective at low concentrations, allowing manufacturers to use smaller quantities while achieving desired texture and stability.
Safety Assessment
According to FDA records, this specific additive (CAS Number 977011-92-9) has generated zero adverse event reports and zero recalls in the United States. The hydrogenation and superglycerination processes produce compounds that have been used in food manufacturing for decades with established safety profiles.
The safety of hydrogenated oils has evolved as a regulatory consideration. While partially hydrogenated oils became controversial due to trans fat concerns, fully hydrogenated oils like this one do not produce significant trans fats, making them distinct from the oils that faced regulatory restrictions in recent years. The superglycerination process further modifies the compound, creating an emulsifier distinct from simple hydrogenated oils.
Based on typical composition and processing, the compound would metabolize similarly to other modified fats and oils consumed in the diet. The glycerol component is a naturally occurring substance found in all fats and oils.
Regulatory Status
Importantly, this specific additive has not received FDA GRAS (Generally Recognized As Safe) status, which means it has not undergone the formal GRAS notification process. However, the absence of GRAS status does not indicate unsafe use. It may be approved for specific uses through other regulatory pathways, used in foods at levels below regulatory detection thresholds, or used in markets outside the United States with different approval frameworks.
The European Food Safety Authority (EFSA) has established safety assessments for various hydrogenated and superglycerinated oils, typically finding them acceptable for their intended uses at standard dietary exposure levels.
Manufacturers using this ingredient must comply with FDA regulations regarding food additive labeling and declaration requirements.
Key Studies
While specific peer-reviewed studies on this exact CAS-numbered compound are limited in public databases, the safety profile builds on extensive research into:
- Hydrogenated vegetable oils and their metabolic fate
- Glycerol monostearates and similar superglycerinated compounds
- Emulsifier safety and digestive tolerance at typical consumption levels
The lack of adverse events and recalls, combined with decades of industrial use of similar hydrogenated and superglycerinated oils globally, provides practical evidence of safety at authorized use levels.
