초록
The aim of this study was to evaluate the product quality and function properties of hot pepper (green and red) fruits cultivated by organic and conventional agricultural practices. Organic and conventional hot peppers were analyzed their product quality with respect to pH, soluble solid, hardness, and color values. The soluble solid contents of organic hot peppers were 2.6~10% higher but their hardness was slightly lower than those of conventional hot peppers. Hot peppers were further analyzed their functional properties on chlorophyll contents, ASTA (American Spice Trade Association) value, total phenolics, and SEM ultrastructure. In case of green pepper, organic hot pepper showed higher (-)a value and the significantly (p<0.001) higher amounts of chlorophyll a and b than conventional hot pepper. Interestingly, organic red hot pepper showed higher (+)a value than that of conventional one. The ASTA value of organic red hot pepper was 28% higher than that of conventional one. Regardless of the fruits color, total phenolics content of organic hot peppers was more enriched than those of conventional ones. These results suggest that organic hot peppers exhibited more excellent color quality and functional properties than conventional hot peppers regardless of fruit color.
