Carrot sample CS-2 was pretreated by steam blanching for 2 min using
an autoclave (CERTOCLAV CV-EL GS, Austria) operating under
atmospheric pressure conditions.
All assays (US and conventional) were performed in duplicate.
After treatments, samples were cooled in an ice-water bath and
conveniently drained and dried with absorbent paper to remove
the excess of distilled water.
