The effect of solvent type on Total Phenolic Content (TPC) was also studied. TPC was determined using spectrophotometric Folin-Ciocalteau method and external calibration with Gallic acid. The obtained results showed that water was the most efficient solvent to extract total phenols from Salvia officinalis L. Moreover, texturing and expansion by DIC pretreatment had a great impact on polyphenol yields and revealed greater extraction kinetics. Likewise, drying kinetics of DIC-treated sage was enhanced compared to the raw material. DIC-assisted extraction can be considered as a promising technology to use in the case of the Moroccan Salvia officinalis L. as an important Mediterranean source of natural phenols.
