Abstract
The influence of common home processing methods was investigated on the color characteristics, phenolic component, antioxidant activity (2,2-diphenyl-1-picrylhydrazyl [DPPH] and ferric-reducing antioxidant power [FRAP] activity) and the levels of γ-aminobutyric acid (GABA) in cowpea pods. The processing methods significantly increased the total phenolic content, total flavonoid content and the activity of antioxidant compounds (DPPH and FRAP). The GABA content sharply decreased in pods after boiling and drying treatment. However, it significantly increased after fermentation. The fermented cowpea pods displayed the highest content of phenolics, flavonoids, GABA and anthocyanin as well as antioxidant activity. Hence, these traditional domestic preparation methods could be recommended for the food industry.
期刊介绍：
"Italian Journal of Food Science" is an international journal publishing original, basic and applied papers, reviews, short communications, surveys and opinions on food science and technology with specific reference to the Mediterranean Region. Its expanded scope includes food production, food engineering, food management, food quality, shelf-life, consumer acceptance of foodstuffs, food safety and nutrition, energy and environmental aspects of food processing on the whole life cycle.
Reviews and surveys on specific topics relevant to the advance of the Mediterranean food industry are particularly welcome.
