Function and performance
Antioxidant protection in fats and oils
AC-AP helps limit oxidative deterioration in lipid-containing systems.
Access to the oil phase
The palmitate group makes this vitamin C derivative suitable for oil-phase incorporation.
Study conditions
Oil-system studies tracked oxidation induction time, acid value and peroxide value. Storage trials used 0.1 and 0.2 g/kg at 20°C in half-filled bottles for up to 60 days. These are study conditions, not a general food-use limit or a finished-product shelf-life claim.
