Interesterified: Nutrition, Pros & Cons
Interesterified fats are vegetable oils that have been chemically or enzymatically modified to alter their melting points and physical properties. Commonly used in Indian packaged foods, bakery shortenings, and vanaspati as a trans-fat-free alternative to partially hydrogenated oils, they are still high in saturated fatty acids and may present metabolic and cardiovascular concerns.
Pros
- Serves as a functional, trans-fat-free alternative to partially hydrogenated vegetable oils in commercial food production and spreads under regulated quality standards. [FSSAI]
Cons
- Often high in saturated fatty acids, which should be strictly limited to maintain optimal cardiovascular health. [ICMR-NIN]
- Clinical evidence suggests that interesterified fats can adversely affect blood lipid biomarkers, similarly to or sometimes worse than natural saturated fats. [PubMed]
Key nutrients
- Saturated Fatty Acids — Interesterified fats are typically rich in saturated fats (such as palmitic or stearic acid) to achieve a solid or semi-solid consistency at room temperature.
