| Abstract: | Ultrasound,
enzyme and enzyme-mediated ultrasound assisted extraction processes have been
used for the extraction of dye from pomegranate rind. Optimum parameters for
dye extraction are found to be pH 10, extraction time 40 min and
temperature 50 °C.
The yields for ultrasound, enzyme, enzyme-mediated ultrasound assisted and
solvent extraction are found to be 29.2%, 26.5%, 35.6% and 8.8% respectively.
The dye obtained has been used for dyeing wool and cotton, keeping the optimum
dye bath concentration as 10% and 8% (w/v) respectively. The fastness
properties of wool are found to be very good while that of cotton is only
satisfactory. |
