Abstract
|
|
|
This study aimed to investigate the physicochemical characteristics and antioxidant activity of cereal bars containingvarious concentrations (0, 10, 20, or 30%) of apple pomace (AP). Highest vitamin B1 and C contents were observed in 30%AP-containing bars, but vitamin B2 and B3 contents were highest in the control (0.347 and 3.566 mg/100 g, respectively).
Cutting strength decreased significantly in an AP concentration-dependent manner. Total polyphenol and flavonoid contentsin 10% AP bars were 2.949±0.157 mg of GAE/g and 1.001±0.009 mg of CE/g, respectively. Antioxidant activities wereassessed by measuring free radical scavenging activities, and 10% AP bars had the highest activities, as determined by ABTS(2,2'azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) and DPPH (α-α-diphenyl-β-picrylhydrazyl) assays (0.412±0.008and 0.492±0.021 mg GAE/g, respectively). These results suggested that apple pomace should be regarded a potentialnutritional and antioxidant source.
