Title
Extraction method for increasing antioxidant activity of raw garlic using steam explosion
Abstract

Novel extraction method for increasing the antioxidant activity of raw garlic was proposed using steam explosion. Raw garlic was hydrolyzed by high temperature (183–258 °C) and pressure steam (10–45 atm), and then crushed by the rapid decompression. The antioxidant activity of raw garlic treated by steam explosion was higher than that of black garlic, i.e. aging garlic. The lowest EC50 value, i.e. the highest antioxidant activity, of extract from raw garlic was obtained at a steam pressure of 45 atm for a steaming time of 5 min, but the highest amount of phenolic compounds, i.e. 93.7 mg-catechin equiv./g-dry raw garlic, was obtained at a steam pressure of 30 atm for a steaming time of 5 min.

► Steam explosion was used for increasing antioxidant activity of raw garlic. ► 93.7 mg-catechin equiv./g-dry raw garlic was obtained at 45 atm and 5 min of steam explosion. ► Antioxidant activity of steam-exploded raw garlic was higher than that of black garlic.
