The content
of phenols increased from 5.99 to 17.57 mg/g and total flavonoid content increased from 49.36
to 104.63 mg/g of crackers incorporated with 5% HSR. DPPH radical scavenging activity
increased two fold by increasing HSR up to 5%. HSR containing crackers exhibited darker
L values than none/less HSR containing ones. In sensory ranking tests, acceptable crackers with
pleasant flavor were obtained by incorporating up to 3.75% HSR into the cracker’s formula
