Elaboration, characterization and color stability of an isotonic beverage based on whey permeate with carotenoid powder from pequi

The aim of our research was to elaborate, characterize and evaluate the stability under light/darkness different temperatures (4 25 ºC) color an isotonic beverage based on whey permeate with carotenoid extract powder from pequi, verify its microbiological safety sensory acceptance. 3% (w/v) concentration powdered pequi chosen because it has osmolality (314.89 mOsmol/L) in range hydroelectrolytic beverages light-yellow tint. evaluated for minerals Na (662 mg/L), K (1363.73 total carotenoids (75.9 mg/L) antioxidant capacity by radicals ABTS (10.79 μmol equivalent Trolox/100 mL) DPPH (73.38 mL), had good acceptance athletes remained within criteria during study. coordinate L* undergone less change C*, greater change. condition darkness at 4 ºC showed yellow tint, more than 30 days (t1/2=121.6 day). Due characteristics, potential benefits consumption athletes, besides being isotonic, bioactive properties natural constituents permeate. use permeate, often discarded as effluent, environment.
