Description 858-866
Beetroot stalks are regarded as agroindustrial waste, despite their nutritious and colourant characteristics. The pigments
found in beetroot waste stalks were extracted using an ultrasonication approach in this investigation. Multiple regression
analysis was used to investigate and assess the individual and interaction effects of power intensity, solid-solvent ratio, and
sonication period on the betalains. Under optimal conditions (power intensity of 79.801 W/cm2, solid-solvent ratio of 22.4
g/ml, and sonication time of 26.7 min), the maximum betacyanin (3 mg/g) and betaxanthin (4.36 mg/g) were achieved. All
responses of betalains extracted from beetroot waste stalks showed a significant (P
