Reduction of major peanut allergens Ara h 1 and Ara h 2, in roasted peanuts by ultrasound assisted enzymatic treatment.

Highlights: [•] The study provides an approach to reduce allergenic proteins in peanut product. [•] A sequential process of ultrasonication followed by enzyme digestion was developed. [•] Ultrasound assisted protease digestion greatly increased peanut protein solubility. [•] Ultrasound–enzyme combination significantly lowered Ara h 1 and Ara h 2 in peanuts. [•] Ultrasound–enzyme combination significantly lowered IgE binding of peanut extract. [ABSTRACT FROM AUTHOR]
