Abstract

|
|
Purpose: Granular products were prepared after fermentation of a mixture of rice bran and germinated barley using Lactobacillus and addition of mandarin, broccoli, cabbage, and carrot concentrates. The in vitro biological activities of water and 70% ethanol extracts of the granular products were investigated.
Methods: Total polyphenol and flavonoids contents, DPPH free radical scavenging activities, as well as xanthin oxidase and angiotensin converting enzyme (ACE) inhibitory activities were determined.
Results: Extraction yield after water or ethanol extraction was in the range of 22.9-35.4%, and total polyphenol and flavonoids contents were 10.1-24.6 mg GAE/g and 1.4-11.6 mg QE/g, respectively. The DPPH free radical scavenging activities of the ethanol extracts were greater than those of the water extracts. The xanthin oxidase inhibitory activities of ethanol extracts at 5,000 μg/mL decreased in the order of granular products containing carrot, cabbage, broccoli, and mandarin concentrates. Ethanol extract of the fermented rice bran and germinated barley mixture with mandarin concentrate showed the greatest ACE inhibition activity.
Conclusion: These results indicate that the health beneficial properties of fermented cereal products can be improved by the addition of mandarin, broccoli, cabbage, and carrot concentrates.
