Abstract:
Fruit pomace, a byproduct of the fruit juice industry, is a rich source of nutrients and bioactive components. The study explored chemical composition and bioactive potential of pomace from selected fruits. Results revealed that fruit pomace was rich in dietary fiber (insoluble fiber: 24.15–31.83%; soluble fiber: 0.43–19.71%). Both orange and sweet lemon pomace were good sources of calcium (303 mg/100 g and 581 mg/100 g). Extract yield was high in blue grapes (45.88 mg/100 g). Free radical scavenging activity was highest in blue grape pomace in methanol and aqueous extracts (78.88% and 85.99% per 4-mg extract), respectively. Thus, these pomace could be natural sources of phenolic components.
